ya they made the 4wd wagons from 86-91. they were available with an auto, a 5spd, and a 6spd in later years. when driving around town only the front wheels drove the car, but if there was like 3% slippage in the front then there was a center viscous differential that would engage and power the rear wheels. pretty cool. my next project is to find a good clean one and turbocharge it. you think your crx is a sleeper? hahaha
