Without going to a stroker, which in practical terms means a rebuild every two years, the 292 cam and a good tune (harder to get than one might think...) is probably enough.

Thanks for this post. It's what I feared and probably explains why I don't see a lot of posts regarding seriously tracked prepared supercharged E9X M3s (Schirmer N'Ring rumors not withstanding). And even if there are a few I agree that heat soak could cause timing to be pulled after a few hard 10/10ths laps. This possibly explains why BMW went with a factory style "stroker kit" in the simply awesome and incredibly rare E92 M3 GTS.

A car which in its day the Car Mags raved over. I see nowadays various companies are making stroker kits such as Lang Racing (just a few miles southeast of Huntington Beach, CA) as well as VAC.
