A SC dream come true???

[kregg]

So a guy I go to church with has a SC'd Tacoma, 3.4L, 5 speed and hates the SC... I offered to buy it from him and give him my intake manifold etc... I'm clueless about tuning and have drooled over all of the tech talk in SC threads all over the web. Someone help me out and point me in the direction of what it would take to get these things swapped... I beleive his was a factory installed SC, (has badges)... And my truck is an automatic... I get lost in tons of the fuel upgrades, valve body talk, and piggy back ECU jargon... Help me make this dream come true!

:clap:

My Boy is getting a SUPERCHARGER!!!!!!!!!

I recall you will probably need the larger injectors, fuel pump, 7th injector kit, tuner maybe.

URD iirc has everything you need.

[RunnerUp]

be prepped to spend an extra 1600-2k above what you pay for the supercharger, unless you can find the stuff used (not likely) ive been looking myself, and cant find it used often for much less than it is new

[Nuthuts96]

swap engines, perhaps? it's an expensive investment for sure. one i certainly have "drooled over" but am not in any place to actually bite the bullet... yet :)

[kregg]

I want to grab his 5 speed transmission too... But he won't let go of it!

So I'm pretty much convinced on the URD 7th injector kit. Still lost with the valve body upgrade and anything that we'll need to do to his truck to get it running right after we take off th sc.

[CJM]

IPT trans in hackensack or wayne NJ (i forget now) does the valve body upgrade, if gadget recommends it then I would do it.

Install instructions just to give you an idea of what you're getting into, but it's pretty straightforward:

You'll also need spark plugs and probably some of the plumbing pieces that you can't swap over. I'd recommend a boost gauge too. You can run it without the fuel mods and it will be okay, it's generally not recommended though. As for the valve body mods, I wouldn't worry too much about it.
Congrats :thumbup:

First- Don't bother with a valve body upgrade unless you drive like a maniac. I would get a large transmission cooler (Hayden 1678), a tranny temp gauge, tighten up your kickdown cable, and shim your accumulators if the shifts are still sloppy. Make sure and run good-quality synthetic transmission fluid too.

Next- good choice on the URD 7th injector kit. You'll want to get a wideband kit in addition to it (I'd recommend the Innovate Motorsports one (http://www.urdusa.com/product_info.php?cPath=66_77_20&products_id=1260518542)), a URD 2.2" pulley (might as well), an OBD-II reader, and Denso Iridium IK-22 spark plugs. Probably around $1500 in stuff total.

In addition you'll want to make sure you have control of your fuel in closed-loop operation. If you have a 99+ 4Runner with an AFR sensor, you can get the AFR sensor calibrator built-in to your 7th injector controller. If you have a pre-99 with the narrowband O2 sensor, I'd recommend going the route I did with a pressure switch (as long as you have the Innovate Motorsports wideband kit). http://www.ultimateyota.com/index.php?option=com_smf&Itemid=26&topic=8547.0

Don't forget to read the pertinent Wiki's as well: TRD Supercharger Wiki (http://www.ultimateyota.com/index.php?option=com_openwiki&Itemid=60&id=wiki:trd_3.4l_supercharger), Piggyback Fuel/Timing Calibrators (http://www.ultimateyota.com/index.php?option=com_openwiki&Itemid=60&id=wiki:piggyback_fuel_timing_calibrators), Oxygen Sensor Calibrators (http://www.ultimateyota.com/index.php?option=com_openwiki&Itemid=60&id=wiki:oxygen_sensor_calibrators)

*I forget what year you have, something to look up is the deal with the crank/pulley wobble on some years being an issue.

IIRC it's the 95.5-97's that have the issue to be wary of.

[kregg]

Thanks for the links Brian. I may be getting up with you some more thru the process, as you seem to know a bunch!

[mastacox]

So, what year 4Runner do you have? Details man! :ban:

its a 97 limited Brian

[kregg]

96 Limited
:)

[mastacox]

Well that makes overriding your oxygen sensor's signal both easier and harder, lol.

A '96 means you have a narrow-band sensor like me, so your cheapest option is probably to go the route I went with a pressure switch and utilizing the programmable analog outputs on an Innovate Motorsports LC-1 wideband controller (which you would need anyway for tuning). Otherwise, URD has an O2 Sensor Calibrator (http://www.urdusa.com/product_info.php?cPath=66_72&products_id=1260518747) that achieves the same thing (allows you to richen the mixture in closed loop), but costs $265. Whatever you do, don't get the ESC1 (http://www.urdusa.com/product_info.php?cPath=66_72&products_id=1120100003), it doesn't work.

[kregg]

So when you flying in to help me install it?

[mastacox]

Haha, I don't think I'll be able to fly out... but I will do what I can here on UY :D

[kregg]

I think I can manage the mechanical install of the SC, but the wiring, pressure switches, and computer stuff has me pretty confused. I'm still reading and looking up definitions of words I've never heard before... Tuning is another animal too... No idea what to adjust or where to do it... I'm waiting until I have a good little nest of spare cash before I take the plunge. I don't have to worry about the SC going anywhere any time soon. Reading and shopping and saving right now. The Wiki really helped a ton. Thanks!

Tuning isn't too bad, all you need to do is follow Gadget's step-by-step guide: http://www.gadgetonline.com/U-Tune.pdf
