You will definitely need the engine wiring harness. But then you'll need a GTE head for the cam position sensor and the coil packs that go with it and because a GE engine has higher compression which is not what you want for turbocharging. Then you'll need a GTE upper intake chamber to fit the intercooling piping, throttle linkage, fuel rail, cold start injector, ISC valve and throttle body with all the sensors like ISC, TPS. Don't know what you'd do about the extra knock sensor you need for the GTE harness, GE's only have one. Oh did I mention you will need to tap and drill an oil return and feed line for the turbo? The return can go into the oil pan (not optimal) but the feed, good luck with that. You'll need a GTE oil filter housing for the feed for the oil cooler. Oh and you'll have to drill another hole in the oil pan for the oil cooler return line. You'll also need a GTE water outlet housing for the coolant feed and return lines for the turbo and all the sensors that go with it. Theres probably more I just can't remember right now.

Or you could be smart and just buy a whole GTE!!!
