I'm in the middle of swapping a b16a into my 91 civic Si! I got most of the simple stuff, intake, header, plug and plug wires, clutch and flywheel. I wanted to get about 20-40 hp more, but stay N/A. I would like to stay around a grand???? Is this possible and if so what would be the easiest way to do this!!!!!!! If anybody could help I would be eternally grateful?!?!?
