Turbo 3 cyl suzuki/geo engine with a 2wd geo tracker 5spd trans? They bolt together and it would be a rwd combo.
Give you lots of power(for a 3 cyl) with a good mileage engine that weighs like 200lbs total. No idea how easy it is to find a turbo 3 but it might not be hard to add a turbo to a normal 3 cyl. If you can get the car down to 1800lbs or so then it would still be plenty fast with a combo like that.
Might be a strange combo but at least nobody else would have a similar car
