1999 Boxster Engine Number

[flyingpenguin]

I recently picked up a 1999 Boxster 2.5 with 110K on the odo. It had a few fault codes but with a new oil filler tube they all disappeared and the engine runs strong and the car is a hoot to drive (and that's coming from a guy used to quite a bit more HP's) :clapping:

Today we pulled the tranny to take a look at clutch, RMS and IMS.

RMS has a slight leak and will be replaced. Will pull IMS flange to see if the bearing is in good shape. Looking at Jake Raby's stuff, I tried to correctly identify this engine but am a bit at a loss here. The number is (yes I verified) M962065X03247. I found a list of Boxster engine numbers on an Ausi forum (see below), and believe it should match (being a 1999) up with the M96/22 65X denomination.

So whence the difference of M96/20 65X vs. the M96/22 65X?
