Edit: this thread now also contains the ECM diagrams I have for your use. I also have the entire sections so far available if you want them, though not sure of pricing yet, which are separate files to make engine swap info for the wiring easier. It's over 3500 pages, so if you want to be a beta tester for the disc, let me know.

**There are more manuals going up so check it out and see if your vehicle is in there.


What engine, transmission, gearbox, etc do I have in my Toyota?

Here ya go, courtesy of: http://members.iinet.net.au/~stepho/engcodes.htm


Engine codes.

*Most of these codes came from Matti's site: http://www.geocities.com/MotorCity/P.../tm_index.html
Toyota uses the same option codes across most of its engines.

The first letter is the engine family (T or R for 1970-1977 Celicas).
The numbers before the first letter is the version number of the engine
(i.e. version 1, version 2, ... , version 18 ...).
After the dash we have the options as follows:

B Dual standard carbs (only used on non-twin cam engines, obsolete code)
C Californian pollution control (also most of the world)
D Uses leaded fuel (Super) when base engine uses regular
E Electronic Fuel Injection
F Twin Cam (economy)
G Twin Cam (sports) with multiple sidedraft carbs (unless EFI)
H Unknown but never combined with -B or -C
i Single point fuel injection
II Unknown - possibly denotes L.A.S.R.E
J Unknown, possibly autochoke, possibly another anti-pollution control
L Transverse mounted engine (only used around 1985 when transverse was new)
LPG LPG fuel
M Phillipines market (details unknown)
P LPG fuel
R Low compression for regular (not super or premium) fuel.
S Swirl intake ports (only a few made in mid '80s)
S Direct injection & swirl pot pistons (starting from '97/98)
T Turbocharged
U Japanese pollution control (introduction of "U"nleaded?).
Engine uses TTC-C, TTC-L or TTC-V.
Z Supercharged
So ...
18R-C is an 2000cc R series engine, 18th version, with Californian emmisions control
18R-GUE is a 2000cc R series engine, 18th version, with twin cam head, Japanese emmisions control and EFI
3T-GTE is a 1800cc T series engine, 3rd version, with twin cam head, turbo and EFI
2T is a 1600cc T series engine, 2nd version, with no special options
12T-U is a 1600cc T series engine, with TTC-C pollution control
13T-U is a 1800cc T series engine, with TTC-L pollution control

Note: pitch is the distance between bore centres.

Cross members


A Distance between chassis-crossmember front bolts
B Distance between chassis-crossmember rear bolts
C Distance between front and rear chassis-crossmember bolts
D Distance between centres of top strut bearings
E Distance between lower arm pivot points

Note, spring height depends on so many things and is so hard to measure that I have left it out.

The same gearbox can have different length rear extensions in different cars.
The same gearbox can have different bellhousings in different cars.
However, the central part can still be swapped.
Exception is late AE70 T50 rear extension will not fit earlier T50 core.

Every entry in the above table requires a unique bellhousing.
The A40 column includes the A20/A30/A40/A40D .
The W50 column includes the W40/W42/W50/W52/P51 .
The W55 column includes the W45/W55/W56/W57/W58 .
The T50 column includes the T40/T50 .
The T and G series engines have different bellhousings (clutch cylinder on other side) but are otherwise interchangeable.

W series gearboxes have a separate bellhousing.
Different bellhousings are used to connect a W50 gearbox to an R or M series engine.
Different bellhousings are used to connect a W55 gearbox to an R or T series engine.
Alloy W5# gearboxes are interchangeable with each other.
Alloy and steel W5# gearboxes are not interchangeable with each other.
W50 bellhousings do not fit the W55 gearbox and vice versa.
W55 bellhousings do fit the W56 and W57 gearboxes and vice versa.
W58 bellhousings are only compatible with W58 gearboxes.
All W## gearboxes after 1970 had the same output spline as the A## automatic gearboxes.
Some cars such as the MX13 Mark II came only with a W40 that had a unique rear extension and no W50 option.
It might be possible to use a W50 core combined with the old W40 bellhousing and rear extension.
All members of an engine family (eg 4R and 18R) can share gearboxes.
Input shaft splines may differ.
Flywheels and clutch diaphrams usually differ.
Some Celicas, Corollas and Coronas from around 1982 had the 3T-GTE engine with the alloy W55 gearbox.
Around this time the 18R-G was also available with the W55.
Different bellhousings were used.
Bellhousings for T and G engines seem to be compatible.
The Japanese GX51 Cresta has a 1G with W50 gearbox.
Any W50 and this rare Cresta bellhousing could be used behind a 3T-GTE.
The 3T-GTE normally has a bellhousing for a W55 but can use a 1G bellhousing (clutch slave on other side).

I have heard rumours that bellhousings for C engines are the same for either S or A engines.
One of these rumuors must be false.
Being compatible with A engines is more likely to be true.
The ST141 Corona uses a 2S engine mounted north-south.
Use this gearbox to put a 3S engine into older cars.
You will probably still have problems with the distributor hitting the firewall but you can use a crank angle sensor with an aftermarket computer.
Newer gearboxes have codes at the end.
