hey guys was just wondering if anyone could clear this up for me, im gettin a turbo off of a R33 and i need to kno if the RB25 exhaust manifold will bolt up to my RB30 ?? ive been told that the RB20 and RB30 are the same but the RB25 holes dont line up or something, im confused though as when i was at autobarn today was havin alook around and they had an aftermarket manifold and it said 20/25 manifold.. anyone that knows for sure please let us kno. cheers whoops just realised posted in wrong section could someone please move it to tech exhaust thread, cheers

cheers mate

Im 99% sure 20/25 manifolds are the same and dont suit rb30 can i get a +1? lol

^^^^^ +1 no it will not fit. rb20/25 are the same, rb26 is different and rb30 is different again.

oh ok then thanks for that guys. i was told that rb20 fit straight up, guess not

Twin cam manifolds have a totally different exit point for the gases into the turbo too.
