Im swapping s4 t2 drivetrain...
 

Im putting it on my s5 vert and need to know if i can use the s4 t2 flywheel or do i need a s5 t2 flywheel?

Thanks in advance

What engine is in the vert? You are gonna need a turbo flywheel to mate to the turbo starter and the counterweight needs to match the engines series(s4 or s5).

Its a s5 N/a. so ill need a s5 t2 flywheel and counter weight. and a t2 starter(does it matter what year?)

Yeah doesn't matter. The counterweight is cast into the stock flywheel so you will just need a s5 TII flywheel. The only time you need the rear counterweight is when you install a aftermarket flywheel then you would use the automatic counterweight.
