the turbo is different also, R32 is ball bearing ceffy is plain bearing. also slight differences in the exhaust side.
later ceffys run the rounder R32 style loom plugs, but most are early ones
AFM, coils, CAS and some other sensors are the same as R31 Redtop RB20DET. turbo is also the same as that of a redtop.
loom (bar the plugs), injectors, head is all the same as r32.
