For the 2002 3.2L into a 2000 S replacement that I'm hoping to wrap up soon, I just swapped the whole wire harness (sensor), intake, and fuel rail/ injectors from the engine that was being replaced.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello All, I have a 2001 Base 986 that has a cylinder with low compression (bad intake valve). I really dont feel like going thru the hassle of having the engine rebuilt, and since I am fairly mechanically inclined I was considering just swapping in a new engine. There is a local salvage yard with a 2.7L with 50k miles on it that is in good shape, but I figured if I was going thru the trouble of doing a swap, why not put a 3.2L from the S model in.**** Heres my question: if I get a 3.2L from a 2000-2002 S, is it a direct swap into the base model outside of reflashing the DME? I have been searching the forums and Pelican Parts DIY articles and could not come to a conclusive answer. I was planning on doing the clutch/IMS while I was at it.**** Thanks!

2000 and 2001, yes. 2002 is a little different. There was a thread about the coolant temp sensor that came up recently that discusses the 2 pin connector vs the 4 pin connector and how to re-wire it. The 2002 model has a non-return fuel system vs a return system in the 2000 and 2001 - 2002 has the fuel pressure regulator inside the sending unit in the tank. For the 2002 3.2L into a 2000 S replacement that I'm hoping to wrap up soon, I just swapped the whole wire harness (sensor), intake, and fuel rail/ injectors from the engine that was being replaced. There will be a few other things to swap over if the engine you install is from a Tiptronic, but no compatibility issues other than parts from the old engine.

POST 3Original post

If I get it right, the same MY is fine, right? So if my 2.7 is 2003 it would take a 2003 3.2 engine?
