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?
Is there anyway to add on a device so that you can remove the exhaust piping as an when you need it (ie during racing) & when you want it to be quiet, u can install back the pipe?
