986 engine swap

[SchuttsR1]

Hello everyone!
I recently picked up a 2002 Boxster but found some serious bearing damage. The car came with a 2.7 and a 5 speed.
I have not found much info on engine compatibility between the years. I did see there was some came sensor location changes. I would like to install a 3.2 but even with a 2.7, wouldn’t I be able to swap the intake manifold and wiring harness over so it could run in my car?

There's a fairly exhaustive list of engine replacement options on Pelican Parts site.

The easiest engines to swap will be model year 2000 through 2002. The earlier and later engines will require more extensive modification.
In 2002 986s started using a non-return fuel system where the fuel pressure regulator is in the tank instead of on the fuel rail. If you install a 2000 - 2001 engine, keep the fuel hoses from the original engine. There may also be a different coolant temp sensor (2 wire vs 4 wire, I forget which engines have which). As you suggested, it keeps things simpler if you move your original harness, sensors and intake to the new engine.

Awesome! Thanks you for the help. I have an engine on the way. It’s out of a 2000 so I’ll be doing some parts swapping.
