I hoisted the RX8 today and took a couple of pictures.

The manual TX starter is very similar to what we are using now but
I would not be a bit surprised if it had slightly different
hole pattern. I don't want to take it off and find out.
It is definitely a little smaller.

Paul,
The bolt pattern looks like the standard TURBO starter as does the Solenoid
position.

The difference between the TURBO and the manual (apart from the bolt
pattern) is that the Turbo pinion gear sits 3mm deeper in the housing (at
60mm) that the Manual (at 57mm).

I'm assuming all RX8's are TURBO yes/no !!?

It sure would be helpful to know for bellhousing development -hint ! hint !

I will send a mounting face pattern to check against, you like?

All RX8's are normally aspirated.

I am not sure what you mean by turbo as I have two starters.
One has a 12 tooth pinion and the other a 13 tooth pinion so the
large pilot hole distance from e-shaft center line will vary.
As do the mounting holes BTW. The 12 tooth is far more popular
and is what Tracy designed into his adapter plate.
This one has a 2.625 pilot hole.
12 pinion teeth with a root diameter of roughly 1 inch
and a gear OD of roughly 1.43
Made by Mitsubishi with the following numbers.
70781  and 7107

It will be a few years before the RX8 starters are cost effective.
By that time we might be able to get the starter/alternator Bulent found.
