So I'm going to do the intake manifold machining myself to fit OBD2 injectors. I need to swap is the oil pump, crank sensor, crank pulley, egr, purge solenoid, bypass solenoid and p5m. I know there's a thread but it is unclear. Does it sound like I missed anything? Will I have an issue with the head (different cams) and no secondary butterfly/IAB?
