If so do you have an example of what type of machining would be needed to adapt one of these to a 930 4-speed to use with this flywheel {link}
No, we replace the factory magnetic sensors with more accurate hall-effect sensors. Even Motec recommends replacing the mag pickups with hall-effect when possible to avoid high speed timing errors.

That's a stock factory bracket (cheap), with a little billet adapter we make & sell, and a common Honeywell sensor (also inexpensive).

For your 930:
All 1984-98 engine cases are machined for the factory crank angle (ref) sensor bracket. So you can bolt on the bracket and a stock 964/993 sensor if running a Motronic computer.
Your stock 930 or 911 steel flywheel can be machined for the Motronic 60-2 timing pattern. We offer this service, very economical -- much less than a new flywheel.
If you then want it lightened like an RSR, we can do that at the same time.
If you are running aftermarket EFI, most computers mathematically convert the 60-2 trigger pattern into a 12-tooth pattern, so we recommend machining the flywheel for a 12-tooth pattern from the beginning.
