Hows the motor? Good compression? No problems? If the motor is stil good you could throw a turbo on it. Do you have a b17 or b18a1? A local here in texas named philip has an ls/vtec turbo setup using a b18a bottom end with 170k+ miles on it. He just ran 12.3 @ 116 last weekend. Any motor with boost is eventually going to blow. You might as well put the turbo on until it does instead of rebuilding before.
