If u put a t2 flywheel and starter on an n/a u can use the t2 tranny and rear end right?

i dont beleive you can use the t2 flywheel on an na because the counterweights are different. you would have to have t2 rotors also. but i do think you can use a t2 tranny with an na flywheel. i dont know why you would want to though. try doing a search to find out more

All counterwieghts are the same as long as your stay in your series..

i dont believe thats right because the turbo and non turbo cars have different compression which can only be achieved by different rotors. im not positive about this but it is what i have heard

I'm gonna sound kinad dumb here, but say i had a gtus. could i just change the driveshaft and be set for over 200 hp, or would have i have to swap out the 4.30 rear end?

Ahem....The rear end.....

As the man said. As long as you stay with int the series, you can swap flywheels no matter the compression ratio unless the rotors have been modified.
