I've talked about the csrt4 in other threads before and it comes out to be a great motor in a crap box worse than a neon. The cars make 40 more whp stock than a nsrt but run the same times. High 13s at 100 ish. There 300lbs heavier at almost 3300lbs compared to a neon. There down fall in a strait line is there braking lsd that ruins 60fts and brakes to large for anything smaller than 18s. But the stock turbo supports 400whp and the stock fuel system 500 ish making them awesome from highway speeds.
