1988 Chrysler Conquest tsi

Real clean, rust free, original paint. Runs great. Rear tires have about 1000 miles, front tires are about 60%. Clear coat is coming off on driver front fender and header panel. All instruments work including steering wheel radio control. A/c belt is off although compressor spins, heater works. Driver shoulder harness motor runs when door is opened but does't move on track and harness belt is missing. Engine run nice and trans shifts fine. I bought this to do a V8 swap but have changed courses. It had what I thought was a turbo whine so I bought a repair kit. When I took it apart it looked fine although I did install the new bushings. After putting it back together I realized that the noise I was hearing was the exhaust manifold gasket at the rear of the #4 cylinder.When it warms up it goes away. The motor doesn't make boost and I think the problem is a clogged catalytic converter right behind the exhaust manifold... motor doesn't seem to want to go over 4000rpm which is about 80mph. Runs down the freeway just fine, actually was driven about 1000 miles from northern Ca to kingman Az in the spring. Great looking and handling car.
