Anyone know any ways to get more power out of an '81 Datsun 210. I sold it to my brother and he wants to autocross it. We're going to stiffen the suspension and put wider wheels(possibly 280Z wheels with low profile tires, they fit, but the tires don't clear). Stock it is only around 65hp I think, and I did fairly well at autocross with it. Needs more power. The engine is reliable. I would like to beat some of the VW's there.
