Yeah, that does sound kinda complicated and a little out of my financial range right now. I mean the car runs so it's not imperative I get a new motor. But what about a more straightforward aproach to more horse power. How hard is it to just put in a larger Datsun motor like an A15, or something that is easily available in the States. With the car's weight, I'm not going for something too off the wall, just at least 100 hp.
