Didn't you ask the L4 question before? I believe Greg S had the answer for you, but again it's another way to say Inline 4 cylinder or InLine 4. Stock turbos were on the stock first gen GT models and the second gen did not have a stock turbo at all. There are aftermarket turbos and SC's for the second gens, most notable is Thomas Knight Turbos and SC's. Check out the 2nd Gen perf forum for more info. Who has them personally, I don't know.
