IMHO, the starion turbo swap is the way to go for ease of installation. Nobody that I was able to find builds a kit for the S/C install, so you would need to fab the mounting brackets, drive system, intake plumbing, fi system (unless you use the Starion intake - I have been advised that the Mikuni won't operate under boost). All the Starquest stuff fits in the engine bay, There are at least 4 of us who have been there-done that, and are ready to advise. The a/t is a better choice for either a turbo or s/c install, as it handles more torque than the m/t (blown a relatively new m/t before in a turbo D-50 - weak in the input shaft bearings and layshaft gears). The best way to do this is find a complete donor car. The best models are the 88-89 Starion/Conquests (best fuel system and can run 10psi boost stock). Even in my 85 Starquest system, boost starts under 2500rpm, and you can build 200+hp easy, vs 109 stock. 5.0 Rustangs are dogmeat against a turbo Monty. My turbo Raider runs fairly well on 87 regular, and gets 16mpg+ around town. Best performing vs. easy engine swap I've ever done. Email me and I'll give you the parts list and tips. BTW, I agree on the bad chain guide diagnosis. Loosen the pan all around to avoid tearing the pan gasket. Use RTV liberally on install of the timing cover or you'll get leaks.<P>------------------<BR>Fasteddy - "born under the Stars and Bars"<BR>87 turbo Raider (it'll never be done)<BR>A/T 30-9.50-15s, lsd, Rolling Rock
