This is what has been taking up all of my guitar buying/playing/enjoying time/money/energy. I blew the original Datsun motor and replaced it with a BMW 2.5L engine and transmission. It should be all done in a week or 2. With a mild tune, it will make 230hp, a stout improvement over the stock motor. Should be a blast in a 2400 lb. car! I could post this on a BMW or Datsun forum but I like the people here better... Anybody else working on anything fun?
