You're gonna love my nuts, BAM, delicious -

[Osiris]

Well, I had to make one more trip down to VA this past Wednesday night. My son's 5th grade field trip to VA. Beach was Thursday and he's been looking forward to this for 3 years. One parent is supposed to go with each child and he wanted me to go. :D I left work at 5:30pm, changed clothes, packed a few clothes and then jumped in the old workhorse for the trip. 1/3 tank of gas--no problem, I'll wait 'til Jersey because it's 30 cents a gallon cheaper there....hear a little tick--no problem, been hearing it the whole motor's life and oil pressure is where it's been since forever, besides I put in a quart or so last week. Heading off down the road on I-84 west and cruising quite nicely, got my radio on and feeling good. Uh oh, there was a hiccup. I think I heard a clang that I hadn't heard before.....ohhh no, that's not supposed to sound like that. Was it a one time thing? What's that smell?? Is that just a belt burning or burnt oil smell? I don't know. BAM CLANG BANG!!!!! Ooooohhhhhhh, that's not good. Still running.....barely.....white smoke is all around me. It's coming from under the car and back in through the rear window that is down halfway, over the windshield from the openning in the hood and I think thru the vents! I can't tell, it's everywhere. I've made it a mile now, maybe I can turn around and get back home.......click-kunck.....RRRRRRRRRrrrrrrr....RPMs zero and coasting to a stop. Well, at that point I have stopped the white smoke from billowing out, so that was good!! Only problem is that the motor will not turn over and that is a problem for making power to drive.

When the motor goes KABLAMMO! then the 1UZ goes in! I'll start a rebuild thread as I move along. Yeah for summer project!

Well, it's 7:45pm, I'm 425 miles from home and my son is freaking out because I won't be able to make it home to go on the trip with him. Not so fast my friend!! I jump on Craigslist, find a '97 Jetta about 25 minutes away and buy it that night and leave CT at 11pm, drive all the way to VA and get in at 6:30am to go on the field with my son at 7:15am. He was so happy that I made it and I wouldn't have missed it for the world. We had a great time on the field trip.

[Crinale]

nice story. way to keep thinking on how to go.

and i look forward to readin another 1uz swap :-D

Don't they also come in the 100series land cruisers? Or is that the 4.7 2UZ that was shared with the tundra?

[DHC6twinotter]

Don't they also come in the 100series land cruisers? Or is that the 4.7 2UZ that was shared with the tundra?


Yup, the 100/105 series land cruisers had the 2uz, as well as the 4th gen 4Runner, GX470, Prado, and Tundra (until 2010). The 1uz was in the Lexus GS400, SC400, and LS400. The 3uz (4.3L) was in the LS430 and GS430. It is still used in the current SC430.

In Japan, the 1uz was used in the Soarer and Crown. Supposedly some of the ambulances in Japan had the 1uz too, but I dunno how true that is. Not sure what overseas models the 3uz was offered in (if any).

1uz and 3uz uses an aluminum block, and the 2uz uses an iron block.

And then there is the 1GZ-FE 5.0L V12 used in the Toyota Century... :drool:

the dream motor swap for most of us, and what everyone else said

[Osiris]

So the story goes on and I have been collecting parts....

I went to Buffalo in my '97 VW Jetta!! I came back with a trunk load!

Built a nice motor dolly with 2x8x10 board. Had them cut it into 4 equal lengths. Put on 2 1/2" - 175# rollers. Perfect fit for the motor.

http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/SSPX0272.jpg

Now I just have to get it out. Used my handy lift stand, cranked it up and out and drove the car away so I could lower it.

No I completely understand your reasoning..
I was just saying.. In the rocks, more power and more torque= breaking axles and junk, if you don't know how to drive.

Good luck with the swap, I've been wanting to do a 1UZ swap. Just don't have time and money.

What are you doing for a harness? I've read that Painlessperformance does harenesses for a good price..

[Seanz0rz]

good price for whom? you or painless. i looked into a basic universal one for my vw. it was going to be in the 700 dollar range. thats nearly what i paid for my fricken car!

[Osiris]

I am going to start with the 1UZ harness. I will have to think about that one alot. First thing will be getting it running and in the truck. Then I will determine what is necessary to blend in the wiring to make every thing work well. It's certainly not a weekend project.

[partsman93274]

This topic is one of the few things that make me not want to reside in California. Not having to deal with excessive amounts of emission parts and then go to a smog referee just to fail. California takes the fun out of almost everything. Of course I'm still living here and probably will for the next couples years. Anyway, good luck with your swap and I didn't know that a Jetta has so much trunk space.

[Osiris]

It's not like a Caddy, but I could get two bodies in there!

[Osiris]

I finally can work on my 4Runner. motor is getting ready to come out!

I also have a few suspension items coming from Crinale to give a better stance and slight lift.

[Osiris]

I am going to use the BJ spacers and LC coils to give a little lift. Is it worth it to get urethane bushings on everything now too or stay with the 15 year old stock rubber?

[YotaFun]

Change now, your already in there so why not?
Plus it will make everything feel solid again and help with the alignment later.

[Obi..]

3.0 swap or 3.4?

[Osiris]

I am swapping OUT the 3.0. :smokin:

[04 Rocko Taco]

Only a fool would ever swap IN a 3.0 - If one ever blows up, and you have to replace it, replace it with something else. I'd take my 22R over a 3.0 ANYday.

[DHC6twinotter]

Yeah, after seeing the 3.4 in my 3rd gen, I don't ever want to touch my 3.0 again.

[Obi..]

Had to ask, people swap in rebuilt's all the time. Now then, how are you addressing the transmission bit since your's is an auto? Going w/ the matching case and throwing on an inchworm, or you actually got a hold of a '95-'98 3.4'd T-100 drivetrain?

[Osiris]

Yea, I put in another 3.0 the last time it blew. It was DD and needed it running so paid to have it done. Now, it's not a DD and can work on it as I have time. So I can change it to what I want to do on my own.

I plan on using my drivetrain in the process. What are you talking about? When I get my camera back and there is more or any good progress, I will post up the work here as a build thread.

[Obi..]

For some reason I kept thinking it's an automatic??

[Osiris]

It is an automatic. But I plan on utilizing my drive train with the swap. I'll change internals and this and that, but from trainy/transfer case/drive line will still be the same as before.

I'll post up pics of my conversion as I move along. This will be my first trip inside a transmission so it should be fun.

[Obi..]

I will advise against throwing a supercharger on the '95 trans as well, the friction discs and solenoids simply cannot handle it and I've the pics to show it. :angel:..in fact he went to a 5-speed shortly after also.

**Don't take my feedback and suggestions as bashing b/c I'm not too far of from finally either doing my swap or getting a newer one to do a similar build on. I've done 4 3.4 swaps now and each had it's different quirks. I just need to finally decide to give my drivetrain to Lil'Bro and have some fun..I love my 2nd gen too much to see it go now. We need tech and threads like this in here and honestly I should contribute to it more but w/ customer's asking for privacy over theft concerns around here it's best for me to not disclose stuff or be sneaking pictures. Take plenty of good pictures, write down the electrical changes as like I said some quirks are there, every '95's wiring isn't exactly the same.


I.O.W. Post it up and make us jealous! :D :wrenchin:

[YotaFun]

Try to find the drive train from a T-100 that had a 3.4l, that would be your best bet and a lot more simple and it will be a significantly more reliable drive train.

[Osiris]

I'm not putting in a 3.4l, if that's why everyone keeps saying to put in a drivetrain from a 3.4l T-100. Keep you posted.....

[Obi..]

Gimme a "D"?

Gimme an "I"?

Gimme an "E"?

Gimme a "S"?

..??

[Crinale]

no they are saying get an auto transmission from a 3.4 t100 (a340f). It is passenger drop just like your stock autobox, but it is significantly stronger internally and will hold up much better to the torque of the 1uz than your stock autobox will. (the a340e that u have now barely holds up to the torque of the 3vz :P)

[Osiris]

Okay....I have the A340H tranny, probably worse than the "E", but I am swapping out my "H" valve body for the A341E valve body from a '92 LS400. I will see how well that does. So I am using my drive train, but the internals of the transmission are going to be switched out for the Lexus trans. Surely that is stronger than what I have.

[Obi..]

Seriously a 1uz, sweet! Thanks for clarifying it for me, I was still unsure of the swap..I took a guess at diesel first b/c he mentions Bob in his signature. IMHO I'd swap an entire trans before screwing with the harder option. Well, that and/or use an inchworm adapter and keep the Lexus trans.

[DHC6twinotter]

Have you guys read Cebby's swap thread? IIRC, he is using the stock 4Runner auto tranny with a few parts swapped over from the doner car. I don't remember exactly what was swapped (pump maybe?), but it didn't sound very involved.

[Obi..]

Have you guys read Cebby's swap thread? IIRC, he is using the stock 4Runner auto tranny...


:ban: Mike's build tech stuff's pure theory until I see his chit's finally brought out of storage dusted off finished and running. :rofl:

**Specifically note the continued harassment of Ceb's until we start hearing from him again, o'wonderful webhost that he is. C'mon Mike, chime in pal. :D

[Osiris]

:smokin: or :screwy:, I am putting Ceb's theory to test then. We will see how it goes and hopefully plan to document what is needed to make it work. Hope that it won't turn into a "never done" project like his or the "destined for greatness 3VZ Camry heads on 4runner block frankenstein motor."

I don't want to put the transfer case on the back end of the Lexus tranny. That entails going inside the transmission anyway and so I figure that switching valve bodies is an easier option.

[Osiris]

I am going to remove both the engine and the tranny. Should I take the tranny out first and then remove the engine or is it easier to remove the engine from the tranny in the car and then take the tranny out second?

[04 Rocko Taco]

If it were me (and it's not) if you have a good engine hoist, and a buddy or two, I'd pull it out as a whole. (drain the tranny and t-case, of course)

[Osiris]

Good hoist, for sure. I was worried about clearance with everything trying to take it all out the top because the tranny is so freaking long and the truck is on jack stands. I guess if I lower the front stands after I have fully disconnected the tranny from the drive train, then it would be an easier angle with the rig tilted down, no??

[Obi..]

Worst case you have to air down the front wheels to have enough room to tilt them, but last time we just left the front alone and put the rear axle on stands and it worked out fine w/ the shop hoist.

[Crinale]

"destined for greatness 3VZ Camry heads on 4runner block frankenstein motor."

i seriously researched this at one point, would have pulled the trigger on starting had i been able to figure out one issue, the distributor is on the backside of the passenger side head, which only has a little over an inch of clearance as it sits.

btw, as soon as payment clears i'll start shipping stuff

[04 Rocko Taco]

I guess if I lower the front stands after I have fully disconnected the tranny from the drive train, then it would be an easier angle with the rig tilted down, no??


I would lower the front just in case, BEFORE you start pulling it out. It gets harder and harder to do the further into the process you are. I would get it disconnected like you said, and then lower the front, and just pull it out.

Although, it isn't terribly hard to unbolt the trans/t-case combo and drop it out the bottom either, if you decide to go that route.

[Osiris]

I've never had so much problems getting stuff done. All the bolts are solid on the exhaust, no big whoop will just saw off the exhaust with the Dremel. I went thru two discs before I realized I was using the plastic blades and not metal. :loser: Got that done and everything seems to be unhooked. Even the drive shafts are marked and unbolted, but they are just staying right there. They don't want to let go. Will search for tricks later. I started thinking about taking the tranny off and it occured to me that my motor might be locked up. How am I going to spin it around to unbolt the six bolts holding the TC to the flywheel? I may have to unbolt the tranny from the bell housing and just slide it out from the TC and leave it connected. Actually, I can't do that because the bolts for the bell housing to Tranny connection are on the inside. I guess I have to break down the motor to free it and rotate it like you're supposed to. Damn........

We'll find out later as I am going on a trip for the 4th and won't get back to this until after then. Have a happy 4th everyone.

[Obi..]

Smack the driveshaft flanges w/ a rubber mallet. They've probably been on longer than your wheels. :D

I can honestly say though, I really want to see a 2nd-Gen 4Runner pulling this off. ;)
Toyota Truck Donut! (http://www.youtube.com/watch?v=xIlniA4X5zU#)

[DHC6twinotter]

:drool: :drool:

That pickup looks familiar. I think it was in last months 4WDTYO magazine.

[Seanz0rz]

soak every bolt in PB blaster, at least once a day, until you work on it again. works wonders for your rustbelt shenanigans

[Osiris]

I have all the nuts & bolts off the rear drive shaft. It just doesn't want to pop off easily I guess. Rubber mallet time.

The front one, I undid the bolts on the transfercase side and the bolts won't come off.

So I'll hit both parts with PB blaster and let it soak while I'm away.

That's all that needs doing to yank it out. Then it's on to working with the tranny and the rest of the bit to fit it in there.

[Osiris]

I can tell that the TB is not the cause of this so maybe the topend is okay. Somebody was looking for some heads so I am going to take them off to see if they are good.

Next up will be creating a hybrid tranny which they look identical on the outside and will post up what swaps I did between them.

[DHC6twinotter]

Interesting....was your motor swapped out before? That motor looks like a pre '93 3.0. :headscratch:

Also, just out of curiosity, what year Lexus did your 1uz come out of?

[Osiris]

Yeah, this motor is the 2nd one that blew on me. Hence, the more reliable beast going in. The 1UZ is possibly a '93-94 model. I have a '92 ECU and it does not match the motor wiring connectors. They changed from '92 to '93. I am going to the yard on Saturday and getting a new ECU or new motor wiring plus some other things for the motor. They have several LS400s in the yard and I can run around pull what I want.

[Obi..]

Aww, c'mon man, a little J/B weld, a couple of rags, and some Mother's and that'll buff right out of that block? ;)

Filter'd be the #1 culprit I'd name, then there's always redlining your stuff, but w/ the auto, although not impossible, it isn't as likely to happen.

[CJM]

You ran a fram filter???? WTF is wrong with you???

[Osiris]

http://i498.photobucket.com/albums/rr341/LuZZifer/DoubleFacepalmRickerPicard.jpg

I know.....now....Didn't know back then. It has been over a year since implosion.

[CJM]

I know, Im just busting your balls.

[04 Rocko Taco]

I run a FRAM filter, flame away.
I run the larger Taurus filter on my Taco, but it doesnt clear the exhaust on my '84 22R, so I run the regular toyota filter, still a fram though.
I have, on occasion, run a strong hard drive magnet on the end of the filter to help out holding in any metal.
Almost 200K on the Taco, no issues.
:alert: :alert:Don't worry, I got my fire suit on. :alert: :alert:

Cool...if you have one older than '95, you have the stronger connecting rods. :thumbup:

BTW, did you get the package I sent?

[CJM]

Chris, FWIW I ran a fram once and the engine was so absolutely noisy. Changed back to supertech walmart brand and it went away. The ant-drainback (or lack thereof) on fram doesnt exist so it starves the engine for oil when it starts up for about 30 secs.

[Osiris]

DHC - Yea, I got your package. Thanks.

Now as for the trans. I have decided that I should actually look at taking the transfercase off my transmission and installing it on the LS400 transmission. Both transmissions have the same gearing internally, but the LS tranny is stronger than my glass transmission. The cases are the same. I will need to look at the outputs of each transmission to see, but if the internals are the same, then the output shafts of each transmission should be the same. That would alleviate transfering all the crap over from a perfectly good transmission.

The next thing to think about with the transfer case is how to double up on some information so that the current ECU can control 4WD because the 1UZ doesn't know it.

[Crinale]

Aww, c'mon man, a little J/B weld, a couple of rags, and some Mother's and that'll buff right out of that block? ;)
Sounds like a Bill Caswell answer :P

btw Osiris, did you get the box from me yet? too lazy to find the tracking number and look it up.. lol

[Osiris]

Crinale, it's supposed to be here tomorrow. :clap:

Then I'll have to start trying to get this all together!

[Osiris]

I am going to have to stick with my tranny. The TC and the transmission are 'married' and work as one complete unit.

http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00965.jpg
The green circles show the difference in the "married" tranny/TC vs. the non-married versions. Those openings allow the transmission fluid to flow between the two. In two wheel drive versions and other 4WD, those would be blocked off.

Like so...below is the Lexus trans
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00966.jpg

I decided to swap the valvebodies from the lexus trans to my trans.
A340H TRANS
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00962.jpg

This is after the filter is removed. This is the valve body. There are ~19 bolts holding it down.
IMAGE REMOVED-----IT WAS A PICTURE OF THE LEXUS VB IN THE TOYO TRANS AS SHOWN BELOW. NO PIC OF ORIGINAL VALVE BODY IN TOYOTA A340H TRANSMISSION. Sorry.

Here is the trans with the VB removed. Notice the three green circles. Those are the three items that you need to move from the Lexus tranny to the 4Runner tranny.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00967-1.jpg

Here is the Lexus valve body removed from its transmission.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00964.jpg

This is the Lexus transmission. Notice the green circles as these are the things to move over to the Toyota tranny when you swap the VB. They are from left to right, the electrical plugs that will tie into the ECU, the throttle cable and the cap that is built into the Toyota VB, but not the Lexus VB. Move those things over before you put the VB from the Lexus on the Toyota trans.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00968-1.jpg

Here are the two VBs side by side. The Lexus is on the left and the Toyota is on the right.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00971.jpg

It will just pop right in and fits without any modification other than noted. This is the Lexus Valve Body installed in the Toyota A340H transmission.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00972.jpg

My next part is going to be interesting. The input is slightly different. On the Toyo Tranny, there are 4 friction plates...
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00958.jpg

On the Lexus Tranny there are 5 friction plates...
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00960.jpg

Because of this, the Lexus tranny has a deeper basket. I don't think the input shafts are different sizes, only the baskets that go into the trans. I am going to work on that end tomorrow.

[Cebby]

You calling me out bish? Point taken (and deserved)...

Nowhere to work on it currently plus no time and less money (truth be told, the only things I have to buy are bends for fabbing headers though - maybe a few other things like e-fan & rad). The big ticket left is unrelated to the build - tires...

Hoping to get this thing under cover next month - should have a little time...

Sorry for the O/T. Good tech - nice work.

It got you to login and post didn't it, now help out in this thread so we can finally have a forum member here with one..that runs. :clap:

Osiris (don't even know your real name, I'm Shane) I was wondering how you were going to address the fluid port deal, there's always a dremel and drill bits? ;) Pretty cool how the shell's are so close in shape, etc, huh? I can't remember offhand if the pans are identical or not.. :D

Also since I can see the trans has had the pan dropped before take some experienced advise here, don't run another paper gasket, use only Toyota transmission fipg, or the grey stuff Marlin's been using. The guy's out here will tell you about the time I oil sealed my undercarriage and the fronts of their rigs coming home from MoonRocks a while back. :angel: Just clean everything down really good, including the inside of the trans, remove any oil film on the mating surfaces, lay down a bead of fipg and give it a little bit to just set up, then install the pan, but don't torque the bolts all the way, just halfway or so, let it cure, then go back and retighten it all. it's a little different procedure than on page AT2-62 (http://www.ncttora.com/fsm/1990-1995_4Rnr/Toyota.4Runner.1990.1995/FSM/95toypdf/95rmsour/1995/954runne/at2/valvebod.pdf) but I've found it prevents any pinhole leaks letting trans fluid spray all over down the road.

Hi Shane, Kevin et al. My name is Joe.

and here is today's activity.......

Gratuitous shot of new parts....Will be cleaned up to be "new"...thx Crinale

If anybody has worked on sportbike clutches, then you may recognize what you are seeing and the terminology I am using when I say "baskets" and "inner" and "outer." I find this to be similar to sportbike clutches even if they operate totally different.

When I said before that I thought the baskets are different sizes, I was not speaking about the part on the input shaft. The inner basket that is connected to the input shaft are the same sizes for each transmission. The input shaft itself is longer for the Lexus transmission vs. the Toyota. The size of the outer basket (which is what I call the part in the transmission vs. the part that is connected to the input shaft that slides into the outer basket, hence the name "inner basket" for that part) in whole is the same, but the components which make up the outer basket are different sizes

Okay, so anywho...the baskets are the same, but the Lexus has five friction plates and six drive plates.

Toyota has four friction plates and five drive plates.
http://i498.photobucket.com/albums/rr341/LuZZifer/4Runner/DSC00958.jpg
When you look at the two pics, you can see how the Lexus one has a shorter basket than the Toyota because it has one more friction plate and drive plate.

See the green points out the 5 friction plates and the c-clip that holds them all in. Use a screwdriver to pop it out to remove it from the housing. This will free the friction and drive plates. Keep them in their order at all times and know which one is front and which is back.

Don't mind the gloves...I just kept them on after I gave those free exams on the corner. :thumbup:

Well, to get the outer basket out I have to use a circlip removal tool which I do not have one that is large enough. I will have to forego the weekly $15 hand job from the corner meth head and get said tool.

Here is a pic of the circlip. the ends are about 4 inches apart. The ends are up in the shaded part up top.

Tomorrow is another day....

[DHC6twinotter]

Very cool...I'm loving this thread. :thumbup:

[04 Rocko Taco]

Indeed, good tech, and a great posting!

[Obi..]

Ohhh-oohhhh!! Advanced fluid propulsion dynamics!! :D

Lexus uses more drive and friction plates why class?

Now correlate that into why there are different valve bodies. ;)

[Osiris]

to handle more power and smoother shifting :headscratch:

I am not an engineer, but I did stay at a Holiday Inn one time! :D

[Osiris]

Okay, so the transmission is complete. I've never been inside a transmission before so I hope it works. All the parts fit and interchange for what I did so those that know about transmissions can hopefully help out if there are problems to begin with.

I will pick up another tranny to have as a back up if there is a need to upgrade because this fails horribly.

I'll post picks of the final piece that I changed out. It was actually very quick when I did the second one (my A340H) and the parts just fit perfectly. Now I have one extra friction and drive plate, but that is the only part that I changed other than the valve body. We'll see.

[Crinale]

good to see that all the parts got there in good shape :D

are the D and P still ledgible on the lower links? i forgot to check. but they are labeled for driver and passenger. The tabs in the middle of the links were added by the guy i bought them from to add limit straps.

[Osiris]

I'll check on the D & P. Didn't know to look for it.

So you fixed your sig and Yota-less.....put in the E30. You should lemonize that e30! Already lowered, race it, biotch! I'm going to build my lemons project after this one and finish my Z's.

Well, on to this one. Broke down the 3.0. It was destroyed in there. I didn't even see a connecting rod in the first cylinder! Didn't look like any top end damage, but the heads look and smell like ass. They are virgin heads that are mechanically sound so would they be good to sell as a set for rebuilding and using? How much, $100-$200 for the pair? I'll post up pictures so you guys can let me know. Anything else worth selling on the motor?

[Obi..]

..Anything else worth selling on the motor?


Post it as "Genuine Toyota Factory Boat Anchor! FREE!"? :D

[Osiris]

Crinale - I see the D & P on the lower links. Thanks.

Here's pics of the destruction.

The one on the right is the one that busted the rod end.

Pile o' busted parts that were left still inside the motor.

Here's the heads. They're nasty, but should be good. What do you guys think?

Here's my 1UZ attached to my A340H auto tranny. It all buttoned up nicely. I hope they play nice.

[DHC6twinotter]

Fantastic! Thanks for the updates!

[Obi..]

Joe it looks really good so far. :thumbup: I just noticed you went back a few pages and edited the posts to reflect the topic better. :D FWIW if you run into any ?'s, Rob Alanis has been doing the swaps into 1stGen Runners with wiring and functional A/C and cruise control, even custom dashboard inserts. He'd be a good reference source if it came to it and you can't get the answer through lextreme.com ~I won't say where you can view his builds but here's his channel on youtube: http://www.youtube.com/user/rmalanis

[Osiris]

Thanks guys. I've been sick all week even though I went to work and then this weekend I was too sick to work on it except for freshening up the rear links I got from Crinale.

First couple of coats on. Might do a clear over it.

[Crinale]

def look better.. if u couldnt guess, i was more of a function > form guy with them :P

[Osiris]

I usually am too, but I am trying to keep it as protected as I can in this NE rust haven area!

[^VooDoo^]

Came across this thred searching for a340 info, Great write up.
Im jelouse.

Somone mentioned that the a340 can barely handle the the 3vz but in alot of articals I came across during my search this is the same trans used in the Supra of the same years And Im seeing alot of 400+hp builds and no problems.
Albiet there not trying to turn big tires and the jolting impacts of rocks.

[slosurfer]

Any updates???

My headgasket blew on mine, so I need updates!!!!

[Crinale]

The a340 in itself is not a problem, its actually the same auto thats behind the first gen tundra with the 4.7 v8... the problem is the VERSION of the a340 that is behind the 3slow. The a340h i believe it is, with the integrated transfercase, has a comparatively weak valvebody and smaller torque converter.. the later a340 (f?) that they put behind the 3.4, and other engines was a VERY nice transmission

[Obi..]

^That and honestly IMHO Aisin never intended the pre-1996 A-series to push anything bigger than say 28's. Heck they were originally drawn up for Volvo's use. Maybe someone ought to look into integrating Volvo control boxes and valve bodies and see if it works better b/c up until the Tundra's started blowing clutch packs Toyota still held onto the belief everything was all honkey-dorey.

[Obi..]

O/T.. @Stover, FWIW I know of someone with a 3.4/Auto combo and know that both Marlin (Marlin Crawler) and Jim (Inchworm) have started considering a transfer case like the lefty but for earlier gens instead to stay off the shortage of RF1-A's*. Complete body and engine harness too. Would make a sick drop and swap for yours. I'd do it if not flooded with bills right now.

That or buy my 3.0/5-speed so I can lay out a down payment on the stuff? :fishing:

*Depending on your auto you can always just swap on your case too.

[slosurfer]

If I swap something in, it's not going to be another v6....go big or go home, or just do the rebuild. Financially the rebuild is the way to go, but I'm just looking at options.


That's why we need updates here :laugh:

[Crinale]

Its been a year since we last heard from Joe, wonder how the rest of this went? Or if it's sitting in his yard like Cebby's :chair:

[DHC6twinotter]

I'd like a bit more power in my 3rd gen, and I'm thinking a 3uz would be really nice. :D

[Crinale]

I'd like a bit more power in my 3rd gen, and I'm thinking a 3uz would be really nice. :D


XD The jump from 3vz to 5vz has you power hungry I think, haha

[DHC6twinotter]

LOL...yeah. The 5vz is definitely an improvement over the 3vz, but the 3rd gen isn't that quick either. I don't see building this 4runner up the way I'd like unless I have more power. Who knows, maybe I'll just wait till I can get a 4th gen, 5th gen, Taco, or 100 series to build up. I dunno...we'll see.

[YotaFun]

Supercharger makes the 5vz go a long way...
I think the 3.4l is plenty power for the truck, even when I have the 35s on with the 4.30 gears (soon to be 4.88) I can still cruise comfortably at 70 and still after a very long run on flat land make it too 100..

What your really missing is the torque, something the 3.4l does not have, the 4.0 on the other hand, that would be a motor I would love to have in my Runner.

[DHC6twinotter]

Part of me wants to add a supercharger, but part of me is concerned about reliability once a supercharger is added. I haven't run across any fuel solutions that I like either.

[Seanz0rz]

i am starting to seriously look into the 1gr-fe swap.

[Crinale]

Sean - Swapping a 1gr is incredibly difficult... from what I've seen a 1uz swap is easier than 1gr. Mainly because EVERYTHING is computerized, and you basically need an entire donor truck to rip all the control modules and crap out to make it work

[Seanz0rz]

kevin, that's pretty much the plan. i want an auto, at least 5spd (does toyota offer the 6spd auto?) so the easiest way is to get an entire drivetrain from an FJC, Taco, or 4Runner and swap it in, all the computers and everything. basically all i have to worry about from that point is getting it all to fit, brackets and mounts, and dshafts.

[YotaFun]

Kevin, if he can pick up a drive train from a FJ cruiser, it will be a hell of a lot easier to swap in then a 4Runner or Taco, due to the fact it still has a J-Shift t-case, he would also want one that doesn't have the diff lock, so the 4wd ecu won't go crazy.

You will need to get a accelerator pedal out of a 01-02 since they switch to TBW in 01 and the FJ is also TBW.

I have actually started thinking about the swap more and more as I extend my time at a Toyota dealer

[DHC6twinotter]

I'd want a 1gr with a 6spd manual if I was going to do it. :D

Would the gauges have to be swapped as well?

[Seanz0rz]

probably. id be willing to tackle that as well.

[YotaFun]

Yes the gauges would have to be swapped, if you want to stick with the 3rd gen look you could get away with an 01-02 cluster just for the digital ODO, vsc and trac lights.

The FJs do have the main light but you can avoid that, it wont make the engine run different if its on.
