No 2.3L unless it's a deisel.

The major mechanical differences between an 86 and 88 models are basically the carb and exhaust...non-feedback carb and a pre-cat in the exhaust manifold. There may be differences in the interior fabric and steering wheel, depending on build date. The gas cap door may or may not have a remote opener. Pretty much the same thing.

There are a few Gen I 2-doors on the Sac Craigslist. There's a real peach white 4-door on the San Francisco CL. You could now go with a Gen II or buy GhostRaider's 2-door V6 on the classifieds here.

Best of luck!
