i heard that motor trend or some other car magazine tested the greddy turbo with more options that it usually doesnt come with like an intercooler, bov, etc and a jrsc (with nothing else) on an integra. the integra w/ just the jrsc ran faster from 0-60 and in the 1/4 mile than the greddy turbo. i dont remember which greddy turbo, but it says this on the jackson racing website.
