Might consider a 2.2L Turbo. If you find a parts car, get complete engine w/accessories, radiator, fuel tank with pump, wiring harness, logic and power modules,and transmission linkages. I did a conversion on an Omni and it was all bolt-in. The turbo will give about 50% more horsepower, but it feels like double due to the increased torque over a large rpm range.
