just get a blox manifold
i hear the B20vtec hybrids produce a pretty damn good bit of torque.. but thats jut what i hearRex_89 said:I agree, go with B20 bottom end and B16 head. Should give you more then the poormans (GSR block and B16 head) because of 2.0 over 1.8. Unless you plan on boring it out. Then it might be better to bore out the GSR bottom end to a 2.0 because it will have the better sleeves. Just my opinion.
