Hey just a quick question..

I know its probably going to be no but an RB20 head gasket cant be used on an RB25 can it??

Also in my old blown RB20 i dug out the pistons this arvo and ended up being 50thou oversized as i was told they where.... Can i use these an an RB25 if its bored out...?

Cheers

Head gasket - don't think so.

Pistons - definitely not (RB25 is 8mm bigger bore, your RB20 pistons are only 1.25 mm bigger than standard).

And the RB20 pistons are flat-topped, while the RB25's are domed. So even if they fitted, you would have much reduced compression ratio.

oh fair enough thanks.... just asking coz i pulled apart my old motor today and got the copper head gasket from it and also pulled out eh pistons and am thinking of building up a RB25 but guess i cant use those parts any more..

Anyone might be interested in them at all?? Ill have to sus out the condition of the pistons but the head gasket is 100% :huh:
