you can use an LS computer just as well as the B20 and the LS are more readily available, Just get an OBDII P75 or OBDI P74/75 and conversion harness (Thats what I reccomend), I also reccomend a Hasport Mount kit and you can use axles from any 94+ Integra (LS/RS/GSR/whatever) or 99-00 Si axles.... Good luck with your project and if you need anymore help just post....
