Well I just bought my motor... B20B with 70,000 Miles on it. Perfect shape, everything is in order. With a Stage 3 ACT Clutch, combined total to $550. Not bad, I'm pretty happy about it.

However, it doesn't come with a Flywheel. I would like to go lightweight, but I'm wondering: What Flywheels are compatible with a B20B motor, linked up to a B16A Transmission?

Thanks in advance,

 

I want to know too.. but B20B with GS-R tranny..

 

All b-series flywheels are the interchangeable.

Lemme correct myself before someone jumps in and says i'm wrong. The flywheels interchange, but the cable/hydro clutches are different.

 

any b-series flywheel is cool. go with ITR if you can.. oem quality and a little lighter.
