carries them last time I checked.

I wouldnt cahnge the motor at all out of it. I think the 1st gen DSM motors have the most potential of any. Something else you cna look into if finding a wrecked AWD car at the junk yard, (head on collision) and take the tranny and rear out of it to convert your car.

If your car is working right now with that problem or you have another beater car. But a 2.0 Turbo motor and build the shit out of the engine. Do everything you can to it with you income and then plant that baby into the car.

I want my 1st gen back stupid ass non DSM 3rd gens
