dude. cheap option. d16z6. it's obd1 so you don't have to fuss with much. It's a bolt in swap for that car. Vtec motor 1.6 liter. about 125 hp to the crank stock. Basically you would need the motor and the ecu. the tranny, axles, motor mounts, tranny mount, wiring harness pretty much everything works from your car. In fact there are a ton of people who have done this exact swap. Write ups are probably easy to find. The b18 is also a good cheap option, you could go jdm d15b about 130ish hp. I've seen everything from 1.5 liter motors, to 3.5 liter motors in these exact hatchbacks man you can pretty much find mount kits for any honda motor in this chassis.
