intake manifold

[eulalia]

i was curious if the rb25 intake manifold could fit on a rb20?

My first guess is yes, but I would suggest checking with aftermarket (Greddy) manufactuers, and see what their application list is for the RB's.. meaning see if they have different part numbers for RB20 and RB25 manis. That's tell ya they're probably not the same.

you would have to call greddy and ask them if it is interchangable. there is no manifold for the rb20 on their site.

i have both manifolds and the bolt patterns are the same . the runners on the are just a larger diameter hole for the rb25 , so you would have to port the head to match .
