'88 is the M50 or M20? Either way, you can make anything fit. It won't bolt on as the 4 cyl engine is smaller and has different mounting points than the 6 cyl. You would have to relocate all the engine mounts. Aside from that, it's just a matter of obtaining all the parts, computer, suspension, clutch, tranny, exhaust, etc.

I think it's posible to swap engines. But... In europe it's illegal to do so. Our car papers tell the number of cylinders. When you crash and the police decide to perform technical research and find out youre driving a car with 2 more cylinders they can sue you. This is in europe I dont know if this is in the states as well.
