I have a 00 Si, my friend is selling his H22 kit that comes with a drag T2/3 turbo, Greddy intercooler, some custom BOV, and who knows what wastegate. He hardly used the turbo before his car was stolen. I have a busted drag kit for a GS-R and I was wondering two things: FIRST, would the exhaust manifold from the GS-R kit bolt onto my head and SECONDLY, would it be worth $900 for my friends kit. Thanks for the info.
