Rb25 Clutch Problem

[r34gttneo]

so i have been doing some research on rb clutches everyone says they are all the same.

so my problem is i have an RB30/25 with a r33 rb25 gearbox, i have an rb20 clutch from a previous car(to save money i thought i would use this clutch). so gearbox was put on the engine and now it won't turn over, so i dropped the box and the engine now turns over. my question is can the rb20 clutch really be used with the rb25 gearbox.

i no people will say research this, and i have and it looks as if it works - but mine doesn't.

cheers

which fly wheel are you using? as the 30 and 25 is different so clutch is diff.
