just the obvious and some random wierd stuff like the 2.3 has the fuel pump in the carb and the 2.6 has it in the tank some lines go different places and the 2.6 can have the impulse turbo exhaust manifold bolted up. but if you wanna get froggy the heads off the 2.3 will bolt up to the 2.6 and will still work right and raise the compression of the motor check out isuzupup.com/forum they have a whole section on pup performance and wierd little motor tricks
