some more info 🙂
the 58mm standard z22se tb bolts straight on 😃
the usa guys use the standard tb, probably due to the 2.4 tb being too big for a standard engine dunno..
if you don't have cams, head work, etc you don't need the 2.4 tb cheers..
the inlet runners are massive compared to the 2.2 inlet :shock:
so much better designed, no wonder the usa guys love it 😃
