You can't just slap a turbo on a naturally aspirated motor. It'll disenigrate the pistons in no time flat! You need to find a turbo motor. Your best bet would be to find a donor car. '83-'88 Thunderbird Turbo Coupe or '85-'89 Merkur XR4ti. The only difference between N/A and turbo motors are the oil drainback hole in the block for the turbo and most importantly, forged/dished pistons. With a donor car you also get the computer, VAM, bigger injectors, wiring harness, transmission, beefier rearend and a bazillion other parts you can either use or sell to recoupe some of your investment!
