Build journal: special series

Rattles that bite.

The S54 is a flawed Ironman, with potentially catastrophic internal failure points.

It introduced M owners to rod bearings nightmares and the joy of VANOS rattling the S54 into probable implosion.

Fortunately, it can be permanently fixed.

In this Special Series, I document the bulletproofing of my S54 with a slight detour in internal performance upgrades: let's cam it!

Enjoy,
