Another Swap Question?, Need some info on exact parts Options

If you go with a 2nd gen you will beable to get alot of after market parts & stock parts because the 2nd gen came to the U.S. on the mr2...

1st and 2nd gens also came in the celica all-trac.

I'd go with 3rd gen. The engines all share the same "Essential" parts, such as waterpump, timing belt, gaskets, etc... The Only major differences is the intercooler, turbo, and ECU (MAP)...

so your saying the 2nd and 3rd gen both fit with no problems

Have your researched this at all? A 3sgte is a 3sgte, they both mount the same way. The wiring is going to be different from year to year. There are a few suttle differences between generations, types of turbo's etc.. You really should take the time and search.

Alrighty then,,, this is what i mean by the silly arguments. This whole web site is about what everyone has done, correct? Ive done a lot of research, and searching on here, read all the forums, and this would be called researching also.
The only way to know if something is a sure thing when it comes to swapping is to talk to people that have already did it. The things im trieing to find out is like the wiring, you say on certain years the wiring is different. Well those are the things i want to know. As for rushing into things, i have not bought anything yet. And im not purchasing in till i have all the facts.

Here is a list of differences:

- MAP sensor instead of AFM
- Bosch D-Jetronic (Gen III) vs. L-Jetronic (relatively primitive) engine management
- CT20b turbo replaces CT26
- Boost raised from 10psi to 13psi
- Fuel cut raised from 12 psi to 18 psi
- Different ECU
- 4 wire O2 sensor
- Shim under bucket valve shims
- slightly more aggressive cams
- Revised internals (pistons, con-rods etc.)
- Revised cylinder head cooling passages/water jackets
- Revised intake manifold (8 'independent long ports' reduced to 4)
- intake manifold inlet air temperature sensor added. i.e. after turbo and intercooler.
- lower compression ratio
- stainless steel head gasket
- factory 540cc injectors replace 440cc injectors
- revised fuel rail with bigger bore and relocated pressure regulator
- TVIS eliminated
- EGR eliminated
- throttle body increased from 55mm to 60mm
- inlet valve lift increased from 8.2 to 8.7
- intake manifold inlet air temperature sensor added
- Less restrictive exhaust elbow
- Aluminum oil pan
- more rigid alloy sump and additional oil baffles
- Factory Catch can
- Better Oil Cooler and relocated oil filter (bottom)
- 4 Channel ABS coupled with Traction Control available
- No. 1 compression ring described as 'stainless steel' instead of just 'steel'. Oil ring is described as 'stainless steel' instead of 'a combination of steel and stainless steel'.
- The fuel pressure raised from 36 PSI (2.55 bar) to 41 PSI (2.9bar)
- air to air intercooler is replaced with air to water intercooler.

keep in mind, I doubt you wanna put a an OBOI engine into ur OBOII car. It can be done, but what a wiring headache.

Will they sell the odds and ends that one might need for the swap separately?

i dont believe so...

bboy

Not at all! I have tried in person, over the phone, internet, everything. I have a few parts I am looking for that came up missing during the swap and can't get them.

This is a good thread about some of the differences between the gen II and gen III motors:

Built Gen II or Built Gen III

Pay particular attention to the posts by RickyB and ChrisC. My synopsis if you don't want to read the whole thing is that if your goals are 330whp or under, the Gen III is the way to go (not taking into consideration parts availability issues). If your goals are more than that, both will do the job but there are some good reasons to go with the Gen II.

thanks for all the info, now i can make a decision here soon, i hope.. Rip Mods or 3rd Gen
