I believe you are right, but would have to go back and look. Single row, double row, etc. So many ways to IMS...but there were a variety of other joys to be had with the last year of the 2.5, or so the naysayers said. I really liked the 2.5, and still do.

Keep the E92 M3, replace the rod bearings and add the 991 to the stable. You will soon realize that you enjoy both for different reasons.

Thank you all for your input! I really appreciate it, I am glad to hear that those engines are bulletproof.

I agree, but due to my job I usually change countries (in Europe) every 2-3 years, it's such a hassle to keep all the paperwork, inspections both compliant and up to date. But I will think about it :-).
