It depends how much money you are willing to spend..and how fast you want the car. Do you want a 4,6 or 8 cylinder?
Personally i have a 89 CRX Si with a ZC DOHC conversion with a few mods such as: intake, headers, exhaust. The dyno test reported my car at about 160 horsepower....i am completely satisfied with it and consider it a fast, small, gas efficient and reliable car.
I guess a 90-94 Civic hatchback with a b18 swap also might make sense?
