i have an 05 cavalier 2.2 ecotec that i want to turbocharge, i was wondering what people think of the turbo kits on ebay, yea i know they are cheap (400-800) with intercooler and all, but what i wanna know are can you use a "universal" turbo on the ecotec, i know there will have to be some fabrication, bending, welding cutting and all that on a "universal kit but what i want to know is would the setup be effeicent/effective once installed. also what does t3/t4 mean? and what does .63 a/r mean, sorry if im asking old questions just cant find the exact answer i want to mine, any and all input is appreciated thanks guys.
