Mr. Adair

Enjoyed. Thx.

So he is claiming the Mezger started with the 996 ??

Surely this is total BS ? My understanding is that what we call the Mezger is the flat six engine which started way back and was used on the 70s and 80s 911s. My 1981 911SC had a Mezger engine as did my 3,2 Carrera and 965 Turbo and 993 Turbo and 997 GT2 the were all based on Mezgers flat six design with only small differences.
When Porsche brought out the brand new chocolate engines for the boxster/996 to save money they kept on calling them the 911 flat 6 boxer engine etc and it was enthusiasts who started using the term Mezger to differentiate these with the old expensive dry sump engine which continued to be used for the Turbos and GT models. The 996GT3 had 964 crankcases for a while.

I believe that the author's point was that the 996 / M96 engine turned out to be insufficiently robust for turbo and motorsports applications which created the need for the 3.6 4-cam Mezger which later morphed into the 3.8 and 4.0 liter versions.

Interestingly, the Mezger engine was still used in the 991 GT3 RSR race cars until, I believe, 2017. It is a pretty impressive powerplant.

This short article from Total 911 may clear up any confusion. The GT3 (and GT2) Mezger is a true dry sump engine:
