Why do you want Hydraulic tranny??? its just more of a hassle. and if you do, depending on what engine you drop in they make the hydraulic to cable conversion im pretty sure. check out hasports site. I would deffidently go with a b18a and turbo it. I did the same swap in my 90 crx si, and its great. lots of torque. Drag turbo kits make a custom kit to fit the crx with the b18a swap check them out too. I am about to buy one they are around $3g's but should be well worth it. I will let you know
