Damn! Now I understand what you mean by saying your brain hurts..
But how did Jimmy do that with only 7 wires?.... Oh well, seems like I will go with whichever manufacture that bothers to make me one at least 50% PnP

Although I am not building my internal for the first stage, I couldn't help but search about building BMW machines and found this:

I know it is an S85 not M54, but both are Al-Si materials.. They talked about how you need to take extra care when boring these machines.. Is it a secret? A well-known fact that most machine shops know? or some pure commercial BS?
Did you take care of this??
I might even just do drop in piston if it is that hard to bore an M54 and I have not found anyone I can trust back in China..
