Any intestererest in a used STS Turbo kit? I know a guy who's selling his '02 SS and might sell the turbo kit seperate. I'm sure he'd be more that willing to give you a ride in it if you were interested.
Turn it into a YJ.
My YJ is fun as hell to drive around town. Make sure it's got a manual trans and a fuel injected engine, otherwise you're wasting your time.
Keep in mind you'll need to multiply your static loads 10 fold if you plan on the design holding up on a jeep thats bashing around over rocks and such.
