I know there was just a post on where to buy an engine earlier, but im looking for the HF engine (d15?) I want to either rebuild one, or find one in decent condition (30-50k). Im looking for one to put in my CRX as a direct replacement because the engine I have is beat up and will soon need piston rings or valve stem seals (yay). Are there importers that sell the HF engine or would I have better luck calling up junkyards until I find one? then, how much should I pay for it? thanks in advance. I would upgrade, but this is my delivery vehicle and MPG is essential. The higher that number, the more money I put in my pocket instead.
