I just got a call from my auto repair shop, and was informed that the engine in my car was toast. I was just wondering what a SPI engine would run, or if I would be better off to just try to sell the thing. Its got 96k miles on it right now. Trade-in value is 3500 on it. I hate to put the bucks into an engine that would cost more than the car. Any ideas? I had also thought if I do go with replacing the engine, putting a DOHC in. What would this involve?
