I just picked up a 91 civic hb 5-speed, and the 90 or so horses it comes with is laughable. It seems like my best bet for a swap is a B16. but that'll only put me at 160.(2500 bucks later) How hard would it be to swap in a h22. price wise the h22's aren't that far away from the B16, and 200hp sounds a little better.
