OK well besides the R , i helped my girl get a 2k2 si a few months ago ,. i want to boost it and i know there is nothing out for it. But i think i remmeber seeing that there were kits for the RSX, will the kits be interchangalbe? its the same motor, just maybe the engine bay size decreased a bit with the si?
im really curious to know , the manifold is my biggest qustion , the other stuff im sure i could cram in there.

what you guys think .
