Your going to need parts from a Mx3 V6. You can put a ZE in, but you'll need to replace engine mounts, cv axles, fuel pump. If you use the straight neck IM, you'll need to move the brake canister a little. Or swap a curved neck IM from a Mazda Millenia. Probe and Mx3 GS trannys are the same. Mx6 has longer gears, but will fit and work. The I4 Mx is not a straight swap for a ze. It would be easier to sell your I4 and buy a V6 and do the swap. Good luck.
