I have an '87 na car, and a '90 turbo lightweight flywheel, center force clutch and turbo tranny with driveshaft sitting around. My car has a worn clutch, and the synchros are shot. Can I bolt in this set up?
Tried searching this, and couldn't find anything that helped. Thank you in advance.

 

Unfortunately you will not be able to use the '90 turbo transmission, clutch, and flywheel in your '87 N/A.

 

What's diffrent? And where can I research this?

 

I'm not 100% sure but my thought is that the transmission will bolt up but, you would need a custom drive shaft or swap in a TII rear. I hope this helps.

I have the t2 driveshaft. I guess my main concern is the counter weight with the flywheel. How would I know if its the correct one? I have read that it needs to be from an automatic car from the same gen, but cannot find the weights to varify if I have the right counter balance.
And thank you for your help.

 

You don't need a TII driveshaft, you need a custom driveshaft if you intend on keeping the NA rear.

 

Ahh. I assumed that since I had the five lug, and an LSD, that it would be the same as the t2 diff. :/

 

Nope. NAs all had NA diffs, and NAs were both 4 and 5 lug. Only the TII got the bigger TII diff. And just because someone else will say it, no, the GTUs does not have the TII drivetrain.

 

Correct, counterweight needs to match engine series. Identification is a little tricky if you don't have them both in front of you. Check this out.

Edit: They also have the "custom" driveshaft for sale. http://www.mazdatrix.com/g9.htm
