so strictly mechanically speaking, which pre-981 engine do you like most?
As in 1999-2012.

I consider all M96/ M97 engines the same. At our level we consider them all an equal playing field that we can reconstruct.

When the DFI engines started in 2009 another set of challenges were conceived.

The absolute worst engines are from 01-05 model years.

so what makes a 2000 2.7 engine better than a 01-05

are you telling me that my 3.4 996 supercharged engine, project engine is better than a 3.6 996 engine :dance:

thanks

Yes, I would like to know too. I bought a 2003 model as everyone said these were the most sorted 2.7L engines.

Dont get an earlier car if possible they said!

The 2000 is better because it has a dualrow IMSB, the most durable IMSB made by Porsche. The 996 3.4 is the worst choice for forced induction because it has the thinnest cylinder walls of all M96 engines. The cylinders may be out of round already even before supercharging.

Why would Porsche replace the 2000 ims double the most durable they made with something less durable from 01-05

That's a good question, Porsche changed the crank to IMS chain & drive gears around the same time to quiet their operation.
