Its one of them days my minds just not with me.. I got a N/A motor, N/A trans. S4. there was a RB flywheel and counter weight on the motor. I sold the flywheel and the counter weight is still on there. Now i need a S4 flywheel and going to buy a stock one would everything be fine ya think? i just read something about no counter weight on a na.

 

If you are going to use the stock manual tranny flywheel, then you need to remove the rear counterweight that is on the engine now that you were using with the RB flywheel.

 

Ok and i wouldn't run a counter weight?

 

No, you don't need a separate rear counterweight with the stock flywheel.

 

its built in.

 

you need the Flywheel that Matches the Series of Engine(like S4 ,use an S4 Flywheel...S5 then you use an S5 Manual Flywheel).
the Light aftermarket Flywheels are good for s4 or 5..the Counterweight is what makes them Different.
so If the Light flywheel is on an S5 then the counterweight is for an S5 Engine.
it doesn't matter if the counterweight is used on a N/a or TII..it just has to be the same series.
