well here's the deal- I'm currently rocking a 2000 Civic Si with a street JRSC kit (~6psi) on the stock B16A2. The problem is that the car has absolute dogshit for power right off the line until it starts building boost. There was already a 7.5lb flywheel and ITR cams in the car when I got it which I know aren't helping the matter, but I know going back to stock B16 stuff won't help much either. Looking for more off the line oomph plus more power overall would only be a plus. So basically I'm wondering if I should go with a GSR, LS or B20 bottom end. I know the GSR would pretty much bolt right up, would have the oil squirters, would be around ~9.8:1 comp with the B16 head, and would probably have decent off the line jump with the stock flywheel/etc. But I also know I'd get even more tq out of one of the other 2 choices, although that would involve running the external vtec lines and I'm not sure what else. Just for reference- the car is mostly used for autox, some track days and daily street driving. thoughts?
