Flywheel Weights?
Ok, I'm rebuilding 87 TII and I got some flywheel problems. What does the stock S4 TII flywheel weight?
I have 3 flywheels that I removed from S4 TII cores:
1) 27.6 lbs
2) 27.6 lbs
3) 22.2 lbs
Which one is of the correct weight? I know these came for S4s cause I remove the engines myself.

ok, so I got 2 S4 and 1 s5. I was kinda thinking that the lighter one was an s5, damn. that would explain why that motor had more rear bearing wear than usual. Thanks

you have to use the S4 flywheel with S4 rotors. S5 flywheel with S5 rotors. they're all matched sets. the only time you can use a lightweight flywheel is if you use the couterweight for the automatic trans. the aftermarket flywheels are designed with the couterweight in mind, so everything will still be balanced.

he's gonna take that comment and think that using the 22lb flywheel is better when it's not.

Thanks everyone on your input.
