Paul, could you possibly document the geometry and coordinates for the sensor mounts of the crank angle sensors with respect to the front seal or some landmark that could be transfered to a gen 3 or
gen 2 cover?
Thanks, Chrissi

Lets see what I have on this.
This is good info on the RX8. If you blow this up
and use it as a pattern to plasma cut a replica and use the RX8 sensor
everything will work with Tracy's computer.
I am sure Tracy is using this on his current RX8 engine.

Thanks Paul, thats good information. Does anyone have part numbers (and prices?) for the front cover, crank angle sensor, and interrupter plate?

I am not sure a RX8 front cover will fit a 3rd gen.
You might have to fab a steel bracket to hold the sensor
and use the front cover you have now. Pretty simple to do.
Pick up some pan bolts. should take about half an hour.

BTW one does not have to use a Mazda RX8 sensor. Mazda will probably charge
and arm and a leg for it anyway. There are a zillion sensors out there.
A nail with a few turns of wire would probably work. A couple of buck hall
effect sensor will work fine. Contact Tracy (if you can get him to answer his email :))
and ask him for his recommendations.

     Good luck Chrissi. My guess is a sensor bracket would be far easier than adapting
     the RX8 front cover to a 2nd or 3rd gen rotary. the RX8 ignition sensor/trigger is
     a major advance over a 2nd gen crankangle sensor and a minor advance over a 3rd gen.

My response was more in line with not necessarily making something like the interrupter plate and winding wire around a nail for sensors when these are available, we are going to stick with the nice
cover we already have.

I think the problem is the interrupter plate could be welded to the RX8
front pulley. In that case you have to change the belt system. There is
probably a market for low cost RX8 interrupter plates that will fit 2nd and
3rd gen engines.

I was kidding about the nail. Sensors are cheap cheap. Just a few bucks.
Mazda charges about $300 as I recall.
