Can some please explain this (tranny differences)...
Why does a TII tranny fits on NA engine but not an NA tranny to a TII engine? I know that the NA tranny is weak for a TII but I'm asking about the fitment. Or does a TII tranny fits on NA?

The NA tranny will bolt up to the T2 engine just fine. Maybe there will be a bolt in a different place on one but it will still bolt up. I think no one bothers because they are supposedly weak.

wow, that's good to know. Well, maybe just for a project, I'll try to drop in a TII engine on my NA. I'm just wondering how long the tranny will hold up.

the bolt pattern is different at the rear end. its not a bolt on situation.
this info is assuming you are just swapping the tranny. my swap to a turbo tranny involved extending the bolt pattern and reinforcing the flange. simple job.

This is the deal. The bellhousing bolt pattern for all rotary transmissions is the same. However the crossmember mounting position, crossmember itself, driveshaft yoke diameter, driveshaft length, rear driveshaft flange diameter, etc. are all different depending on year and model.
SO technically an NA tranny will bolt to a turbo engine, but it could not be installed in a turbo car. A turbo tranny will bolt to an NA engine, but it will also not work in an NA car. This is why you hear of people doing driveline conversions...everything from the flywheel back is different between a turbo adn nonturbo model...all the turbo stuff is larger.
You can use a turbo engine in your NA car using the NA drivetrain, but your clutch will slip like MAD. www.rotaryresurrection.com tech section under stage 1 turbo conversion.

Depends on the clutch, the driving style, and the engine mods. I did the swap once with a stock t2 engien and stock na clutch, and it slipped like mad. It would break loose in any gear after 4krpm, even if I eased the clutch out at takeoff/shifts before applying any throttle.
I'd say something like an act HD PP and 6 puck clutch would handle the powre just fine, until your tranny broke. IF youre gonna mod the t2 engine for 300hp though, even that might not hold.

I'd be safe and go TII the whole route. If your gonna Turbo the motor, might want to stick with the TII tranny and a TII rear diff. Aaroncake is the guy to talk to on this one... If I'm not mistaken his NA/TurboII Swap is stickied somewhere.

ok, just for me to understand it completely, I can just drop a TII engine on my NA without modifying the drivetrain right? I have an ACT HD SS clutch right now and that should do it ok I guess for now.

Check the weights of the flywheels because the have the counterweights integrated in them. I am not certain so hopefully someone else will see this for the answer If the weights are the same then knock yourself out

Thus, if you have an S5 TII engine, you need an S5 NA flywheel. Tranny series doesn't matter, only the engine and the flywheel series must match.
