'95 awd guts fit in '90 case?

[BoostedPhoenix]

I tried searching and only found discussions about swapping the entire transmission between years. The only differences i have been able to read about are external, Im looking for details on the internals.

I destroyed the front differential support bearings in the '90 trans a few months back (dont ask why i have a '90 trans in a '94...its a long story) and im now getting time to work on the car. I have a '95 AWD transmission and transfer case, from a parted out car, sitting in the garage, i plan on rebuilding one of them as i have read that the 2g trans will fit in a 1g if you really want it to . I know the '90's are different than all others and the newer you get the better they get.

I need the whats hot / whats not info on fitting the internals of a '95 AWD transmission into a '90 case for my '94 talon. Also while i have got it apart, im looking to make the best of the best OEM parts AWD transmission, so is there any thing i could order from the EVO, Gallant, etc that would improve the '95 parts?

Alright since no one seems to know anything perhaps i could get at least some insight as to what to upgrade on the rebuild?

I would stay stock just order all new syncros and such. If you start going with different gears then your rear diff gets all messed up. Order evo double syncros 1-4 if you want it bullet proof.

That is exactly what i was looking for things like that, that make it better than what it is, im not going to admit a horsepower number because i dont really have a goal yet all i know is the parts im putting on the engine and what they are capable of. Im a firm believer in over building the mechanials in favor of durability and longevity. I also belive in using OEM parts where ever possible for driveability purposes and making the car as pleasant as possible to drive on the street. I want the best of the best that mitsu put into a similar car or combination of the parts to make the quickest/smoothest/reliable street driveable car i can. (its ok you can laugh at the that "reliable" part now)

I used a 90 FWD case a while back for ~92 internals. The internals are certainly different (gear diameters mostly), but the cases are interchangable (shafts are still in same place, same height). You can/must swap out the shift boot from your 91-94 to make it work (91-94 has shorter to work with larger diameter gears). This way you dont need to worry about shift cables either. Sorry I dont have 95/2g info, but I thought it may help a bit. Good luck and let us know if you try!

You can't just put double-syncros in where single's were without having machining done. The 95 parts will have a double-syncro 2nd gear.

I have all 90 parts inside my 2g transmission. Some of the gears have a different pitch to them so use all the gears including the diffs. The only thing you will need to keep is there is a short shaft with an end on it that a bolt goes through the case into which holds a gear for reverse that runs off the input shaft. The bolt hole is in a slightly different spot in the newer case.

You my friend, are a GOD this is what i needed to know specifically. I want to use the '90 case because its the only first gen trans i have, but i knew the newer internals had better synchros and what not, just didnt know if the rails were the same or if they would change over.

Isnt there something about a Gallant VR-4 1st gear being better for some reason, EVO Shift forks, and the double synchro idea would it fit with the EVO gears ?

Shep sells all the internals and the kits - as little or as much as you want. Check out their website. If nothing else it'll give you some ideas.

As it sits, its not even up to par with stock even if the transmission would work right .

Long story short, i wrecked my '90 GSX last winter (damn neon drivers cant drive for shit)and transplanted the engine and transmission into this '94 shell i bought to replace it. Only plans i have in the immediate future are the ones that involve fixing the things the previous owner did wrong:

-removed aftermarket alarm (some of the worst wiring mess ive ever seen)
-removed ABS (the pump had already been removed for me )
-replaced tornCV boots on the rear axles
-put a stock fuel pump back in and am saving the walboro 255
-aquirred all stock dark grey pillar trims to replace the "painted" junk thats in right now
-replaced select bushings with urethane
-yada yada yada

I figure i'll fix the car to the point of deserving power before i let it try to tear itself apart. So im building a transmission that will handle what i can throw at it any time i want to, the parts i have so far for the engine are:

-6 bolt block/rotating assembley
-2g pistons (havent gotten rods machined yet)
-2g head (or maybe 1g, i havent decided yet)
-ported 2g exhaust manifold
-E3 16g
-hks 264 intake 272 exhaust cams

Those are the major parts i have stacked up right now, but since i moved into my house in november i really havent gotten anything done on the car
