well right now im trying to gather as much info as i can right now and the lsd must of had a brain fart.....i got the crx for a steal i think but not sure on the motor i want to put in it.....i think what made me buy the crx was that i found a kit for that model black widow for 88-91 crx .but i was figuring if i could get it close to 450 hp it would be perfect for power to weight ratio. it be like having 600- 800 hp in a musle so any help on the best builder friendly engine would be greatful
