Hi stan911.
It looks like a very nice car to drive
Regarding brakes, rear 944T fits nicely, P'N'P.
You need the early 951 rotor though.
What I did for my 931 is front calipers from 997 C4S ... |

Thanks Ciprian, what I’m afraid is the courier losing the package
Currently I can live without the scan. I got the STP file though. But I only have a viewer. Can this step file be converted to s ... |

Ballast resistor is just a wire with resistance, don't look for a regular resistor
What I would do, I'd just put a new wire from the fuse box, or anywhere else close in the engine bay (+12V whe ... |

Would be nice to scan these in 3D and try to arrange one on the other in CAD software to see where the differences are. Unfortunately I don't have access to a 3D scanner and none anywhere nearby comme ... |

I did take the mold of the CNC'ed port.
From top to down:
- stock
- hand ported

Good tools make your life easier. Buy some more material and practise a bit.
I did change in my 931 the awkward X setup (left front / right rear and vice versa) to a regular front and rear setup, fol ... |

Again, nicely done!
Thanks Mike!

Yeah, it was 6 times already ha ha.
I think I will make a mold of this CNC’ed port to compare with the one I have from my hand ported port.

Hmmm... Let me think. The most important thing in CIS is the WUR. This is the gremlin that changes the fuel pressure during the engine run (other than idle). Either cold or warm or part warm or whatev ... |
