G50/52 starter motor

[GT40Lee]

Forgive me for asking a question to do with GT40s here but hopefully someone out there can give me the answers I can't find elsewhere.
What I'm ideally looking for is an uprated starter motor for a 91 Turbo Porsche transmission - G50/52. Does such a beast exist - if so who makes it (Tilton don't)?
I know about converting the clutch back to the 89 version but I don't want to go that route.
Alternatively is there somewhere that can rebuild my starter motor to a higher spec?
I have a 96460410400 which I believe is off the Non Turbo motor. Can anyone tell me what the difference is between this and the Turbo starter 96560410400.
The reason I want an uprated starter is because I will be joining it to a high compression Ford V8.

Are you sure about the IMI 101 N. It doesn't appear to have the reach needed? I think the 101N is for the earlier clutch with the ring gear near the diff. The 91 Turbo has the ring gear near the engine - which is where I would prefer to leave it.

I have found 2 starters which appear to fit. As I understand they are
96560410400 for the Turbo and
96460410400 for the Non-Turbo
I've been told (by Kennedy) that these 2 starters for the later box are identical. They spoke to Bosch who could not tell any difference between the two.
I think Bosch also use two different numbers for the rebuilt versions of each.
Kennedy are not aware of any other starters to fit this box with ring gear in standard position ...... but I'm still looking. I have another couple of leads.

Thanks for the Bosch info. Very useful.
The only other option I've discovered is a Tilton starter with an unfinished shaft which can be cut, chamfered and hardened to suit.
I'll try one of the normal starters before going down that route.
