Rolls Posted May 5, 2009 Share Posted May 5, 2009 Hey guys I bought a 2nd hand rb20det gearbox out of a turbo r32 skyline and a brand new exeddy clutch. Now I got my old flywheel from my redtop (HR31) rb20det machined but the bolt holes don't line up on the flywheel. Is a silvertop rb20det flywheel different to a redtop rb20det? If so can I just buy an r32 flywheel and it should bolt up, or do I need to send the entire clutch back ? Also the gearbox I pulled out was a RP71c not a RB71c which I believe is the non turbo box, could this be the reason for the mismatch?

Rolls Posted May 6, 2009 Author Share Posted May 6, 2009 I've been told the rb30 or rb20 240mm one should bolt up and work fine, guess I will find out.
