Actually there are some pretty sweet engine jobs you can do to an Acclaim, I'm in the same position as you (but with a 1992 Acclaim 4cyl) and want to fix it up because its a solid car. Check the net for a guy called Gus Mahon, he tuned a plymouth acclaim to get the quarter mile in 12.27 seconds! That's corvette territory, although the car would handle pretty rough. Just look for an engine swap from a Spirit R/T with the turbo, factory with over 200 horsepower, and get a turbo upgrade, exhaust, tranny job, intercooler, brakes, and as far as you want to go. But there's probably cheaper ways to get a fast car. As far as exterior upgrades, you gotta do it yourself! Fiberglass bodykits were available on the Spirit R/T that might fit the Acclaim. Other than that, just drop it and give it some rims and an exhaust. That's my plan!
