The rbc is off the newer si. But if you install the rbc (or rrc) the radiator support has the be bent or cut in order to make it fit.
I have a k20a and mods are: buddyclub race header, mugen twin loop, password jdm intake, rrc manifold (from the 07 type r), and i just put blueprint stage 2 cams, supertech valve train and port/polished head. I havent been able to tune it since the new mods. But it ran really strong before. The rrc manifold made and instant difference without tuning.
