The plan was to tear down the BMW’s M54B25 and rebuild it.
The teardown had other plans. 😂
Once I got far enough into it, I found out this engine was junk — which meant the B25 rebuild was officially dead and I had to find an M54B30 instead.
Not exactly the plan… but the B30 was a slight upgrade anyway, so I can’t complain too much. 😂 More displacement, better starting point, and ultimately a better foundation for what came next.
Sometimes tearing an engine apart tells you exactly what you didn’t want to know — and sends the build in a better direction anyway.
