I know the US G20 comes stock with the sr20de and I know alot of people turbo the de and put sr20det's in the car. I have been reading some posts and have heard that there are sr20ve's. The posts have said that the V stands for Vtech. If it does what's the difference. Why do they put Vtech engines only in Japan models. Is there more power than the sr20de. If so how much. Im assuming the det and the turboed de are better though. I just want some clarifaction on this subject.
