I lowered the car first, got suspension all set up then I did on my motor, intake, exhaust, headers on my old engine(2.2 sohc) then I did my jdm h22a engine tranny ecu swap its best thing ever, so if you really want power just do the intake/headers/exhaust for now and save some $$ for a swap. If you want some cheap headers I have some used dc sports headers email me!
