sr20det or the sr20? what do you want to know? www.phase2motortrend.com has some real technical info on the motor i think. www.nissaninfiniticlub.com has a real good sr20det forum. www.heavythrottle.com sells swaps, so does flashoptions.com. it really depends on what motor you are talking about and what kind of car you are talking about swapping it into. there are a few shops that'll do the swap for a real good price around here.
