what flywheel to use on t2 motor with n/a rotors

Gonna build a high compression s4 motor

s4 n/a rotors,and front counter weight

can i use the s4 t2 flywheel? or do i need to use the n/a one? i have counterweights for both

also if i need the n/a flywheel can i use a t2 clutch since its a t2 tranny or do i need a good n/a type clutch

thanks guys

n/a one.

you also need an s4 non turbo eccentric shaft to keep it all balanced, if I'm not mistaken.

well 13b eccentric shafts are all the same right? the counterweights are what keep it balanced

that being said can you bolt a t2 clutch to a n/a flywheel? or would we need a n/a clutch?

keep in mind this is on a t2 tranny

you will need the t2 clutch and flywheel to use a t2 transmission. The splines on the input shaft are different as well as the starter location.

To answer the original question you need to keep the same flywheel within series. Use the S4 T2 flywheel with your S4 N/A rotors and counterweight.

Why is the front counterweight for an N/A a different weight than the Turbo counterweight? Is it just the front counterweight and the rotor (N/A vs Turbo) that need to be matched? If so, then why is there a weight on the flywheel?
