just wonderin' if the flywheel from a 92-95Si(z6) will work in a 91 EX(a6)...I have one I was thinking of getting lightened and resurfaced...what would be a good weight to go to if I was running 11-12psi of boost MAX?

 

it will work and the splines match but the clutch from a 92-95 is a bit larger in diameter so the smaller 91 wont just cover all of the area. id suggest using a 91. but thats just me. it does work though.

 

I thought all 90+ flywheels were 212mm
Anyways if the 92-95 is bigger use it and get a bigger ctuch more hold to

 

90+ flywheels are the same. 88 and 89 had 200 mm clutches, 90+ had 212mm. SO yes, it will work fine, I'm doing the same thing with a lighted 5g flywheel
