RB20 and RB25 Difference.

[contreasjun27]

can a RB25 parts or performance parts be used on a RB20 Engine?
coz I know that for turbo header can be use just plug and play.
What about intake manifold? is it plug and play as well?

Bro the rb25 intake ports are slightly bigger, so you can port and polish the rb20 head.
You have to do a bit of machine works for the studs.
And then the other difference is the injectors. 25 is top feed and 20 is side feed if i am not mistaken
