T2\NA FC Drivetrain, can you identify this drivetrain?
 
ok, so i noticed the tranny that i thought was a NA tranny having ribs on it, and i recall being told the ones that has ### on it are t2 tranny, so could i get a confirmation on them by some of you guys that knows for sure?

Trans is turbo.
See all the raised cross ribs?

Hard to tell the diff, but if the parts all fit together nicely, it's most likely all turbo stuff.

wow that's a relieve. looks like i can make the drift showoff with a proper lsd in the end

is there anyway to tell the diff? the driveshaft doesn't look much like it's aftermarket

and are u 100% sure on it reted? cuz i've heard both sides of turbo having ribs, and a friend recall seeing ribs on his gxl......
i hate it when tha thappens :mad:

Okay, I'm sure it's a turbo trans cause of the drain and fill positions.
I believe the non-turbo trans has different drain and fill plugs.
Pop the transmission off and look at the clutch.
The turbo trans uses a 1" input shaft, and the non-turbo uses a 7/8" input shaft.
The clutches are totally different looking also - the turbo flywheel uses a "flat face" to mate with the pressure plate; the non-turbo uses "raised pedestals" to mount the pressure plate.

And, just to throw another wrench in your theory, I've seen - with my own eyes - smooth case turbo transmissions that come in with J-spec engines.
So, in Japan, not all turbo 5-speed manual transmissions are "ribbed". :)

Hard to tell what LSD is in there, but a quickie test is to spin one side and check which way the other side rotates.
If they rotate in the same direction, it's a clutch-type.
If the other side doesn't spin, it's either a viscous-type or a dead clutch-type - you really don't want either. :(
If the other side spins the other way, there is no LSD in it. :(

hm. isn't the turbo tranny a lil shorter or something like that too? popping the tranny off would be quite a bit of work, since it's not on a hoist and stuff heh...


what type of diff won't matter :) i'm going with a 1.5 or 2way, i just gotta make sure i have a turbo diff to know which to order. The diff right now in the car is as good as useless, cuz it clinks aroudn...
