1. I do not have much fabrication skill
No better time to learn than on a cheap car. Go for the SHO swap (94 and up, though to keep it legal across state lines). Me, I'd look for the 94/95 3.2L. The 96+ 3.4L V8 were known for the cam losing the sprocket at about 50k miles. You could have them welded, but if the shop doesn't balance them right, you're back at square one with a big Cosworth/Yamaha paper weight. Also to keep things easy, I'd look for a centrifugal supercharger to simplify the exhaust routing. Building headers is a lot easier than you might think if you take your time and use your head but mounting a turbo in the way brings teh suck.
Sweet. You could run the pipes as "experimental" and get away with whatever you wanted to run so long as they met emissions (equipment) and noise standards. That leaves the field way
4.I am pretty dead set on a tempo i have one that i want to make it a sleeper..i want the most UNEXPECTED car to beat you on the highway thats it
And that's the root of all that is custom and the soul of hot rodding. I wouldn't do it that way, but if I were
to build a Tempo, the way I'd do it is above. Don't screw around with nitrous oxide as it's way too hard on the cylinders. Yeah, yeah, it runs cooler and generates a ton of power but you can blow the plugs out of the heads if you get too heavy with the injector. Go with water/methanol injection. It's got its roots in fighter aircraft and tanks. Any asshat who says it's not all it's cracked up to be doesn't know jack about it. Tell them to go check out a Saab 99 Turbo S or try and race a B-52- which can carry 488,000 lb at 650 mph. Water/methanol injected engines are usually tuned with a narrower margin of safety allowing for greater compression ratios and largely eliminating the problem of detonation. This would be a very good idea if you plan on using the factory block without significant reinforcement.
Don't waste your time on a Tempo.
1994 Tempo Coupe = 2511lbs
1994 Tempo Sedan = 2723lbs
1994 Taurus SHO = 3,472lbs
I smell a coupe getting built.
