Between any of the 6 cylinder engines that came in a e36, relatively speaking, no. Going from a 4 cyl to 6 cylinder is a little more complicated, but really, it's still fairly straight forward.
That said, keep the 2.8. What you can do though is get a intake manifold from a 2.5 and bolt that on -- should be good for at least 15 horsepower, even without an engine remap.
