The two engines are generally the same but there might be some fine details you will only find out during the swap.

The 95 will have electronic injection, the 93 might still have CIS, I'm not sure. The two systems are wildly different and it would take much work to convert the car. It should be easier to retain the fuel system that came with the car and look for a 95 280 computer.

If the 280 has electronic fuel injection, it is likely the same as the 95 making a computer swap more likely to work.

Have a look at the site 190REV , some have swapped out 2.6 engines for 3.2 and would have a better read on what will work. in any event, be sure to update this thread to help others.
