The first gen crx bible is redpepperracing.
You're better off sticking with motor mods or a first gen integra brown top engine.
It came carbed, and came in their crx. Otherwise you'll need a pressurized fuel system, oh and theirs not the same ecu as most cars today in the dx(unlabeled) and hf. It's more like a conglomeration of pessure valves hooked up to a lil ecu. That means an ECU plus a whole lot of wiring. It can be done, but is few and far between, check out YouTube to find a dx with a b16 in it, all new fuel sys, insane power for ~1750lbs of car.
