It would be a lot of money and time.....think about it, EVERYTHING HAS TO BE CHANGED. Axles, shift linkage, radiator, halfshaft, motormounts, cutting the engine harness and adding/repinning the ECU. Understeering is a HUGE problem. Your easily looking at 4k just for all this stuff and in some cases, you haven't even touched what needs to be replaced on the donor engine.
If I was you, I would look into a K20A. With that kind of time and money spent, the K20a isn't too far from home with the H series. And it would smoke anything.
