Schumi
I do not know the Part Number. I gt mine from the junkyard and from ebay. In a pinch I have several (3-4) on the shelf. I looked up the part on several parts store sites and did not find them. They are actually sold as pairs wired together back to the wiring harness. I also suspect that you may have to purchase the entire eccentric shaft position unit for mazda.
I was looking at the cam position sensors from the 94-98 ford 3.8 V6. I assume that it is a VR sensor but I have not looked at it closely. There are several in the junkyard locally and I should pull one the next time i am there to play with and see.
One of my next improvements / better design will be to use a smaller trigger wheel. Tested and proven installation have used 30 mm 72-2 wheels. I would then fabricate it so it would mount the same way that the stock rotor mounts (suing the same hardware) I would then fabricate a cover that incorporated the VR sensor that used the stock distributor cap mounting. This would be a neat clean install that would then be easy reversible. I also think that it would be much more appealing to 944 owners if installing the trigger and sensor was not more difficult than installing a new cap and rotor.
I am going to put this into Autocad and see what I come up with, Now that I know the principal works I am going to re design and toss a little more $$$ at it. I have access to a machine shop. That has a completely computer controlled 5 axis mill. So once I have it in cad they just make it. We can then see how it works. First I need to find a gear that fits the needs. We could make one but of the shelf is so much better.
