If it's the larger cooler, it is likely a 3.2 (though some have updated 2.7s with the larger cooler).

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

A friend of mine got a 2000 Boxster base as a part of real estate deal. He got the house on auction and the car was included. It's a 2000 Boxster base 5 sp manual (just like mine.. only yellow), however he's been told that the engine was replaced with a 3.2 from S version. There are no receipts or any other proof of that. I helped him change belt and clean the MAF on weekend and we didn't see anything that would say 3.2 when looking at the engine (there was alot of oil.. so AOS might be going bad). He has a newer MAf though it's ending in 125.01 and considering his car was manufactored in 99 I expected him to have 124.00 MAF Is there a way to tell what engine is in his car short of going to a mechanic? We did a series of short drag races over the weekend and he didn't do that good and by short drag races I mean a couple hunded yards we both drive like pansies Thanks Sasha

POST 2Original post

A quick way, though not 100% accurate, would be to have a look at the oil cooler on the driver's side of the engine. If it's the larger cooler, it is likely a 3.2 (though some have updated 2.7s with the larger cooler). You can also look for the engine type code near the crank...I believe the 3.2 is type M96.21. 2.7L (M96/22, M96/23), and the 3.2L (M96/21, M96/24)

POST 3Original post

Jack the car up and crawl under it...on the bottom of the engine is a ID number. Write it down and use Porsche's ID number checker and that should tell you what engine it is.
