1992 Mazda MX-3 GS V6 1.8-Milage=141,000...Hi, I have a question about an engine swap. I want to have changed my 1.8 V6 engine, for the JDM 2.5 V6 engine for my Mazda. I reserched that the JDM 2.5 V6 fits my car, and also is the one that fits the Ford Probe V6 and the Mazda 626. I wanted to know if I need anything else to put the engine to run, for example different motor mounts, or ECU's or something like that kind. Thanks guys

You need everything that goes with the V-6. I wonder why the swap, the 4cyl is a much better engine.

YEs you will need to make some changes when going from the 1.8L [b:43973f386b]V6[/b:43973f386b] to the 2.5L V6. The first and obvious is the intake. You will need to change the intake from the 1.8L onto the 2.5L. Don't worry there will still be a very good power gain in the motor. Changing the intake is the first of your worries. I think you may have some exhaust manifold issues too and make sure you have the correct egr valve on before installing the engine.
