How to Blueprint a 930 Trans..

[doozer]

I have receive a lot of varying quotes on a high performance 930 transaxle and I am just wondering if it would not be more fun to do it myself and document it with photos.

What is involved with blueprinting a 930 trans?
I know I can send the case / shaft to be shortened.
Where do I get specs to compare parts to?

I just have had a lot of different people try to scare me into buying a trans from them because they say that there are people out there who fill them with used parts instead of using new parts in the rebuild.

I think I would sleep better at night if I just built it myself.

Where do you start? With just any used 930 tranny, or is there a better way?

Thanks

Anyone?

Unless it's the last 2 years of 930, shortening the case isn't advisable.

[doozer]

Because of the flange thickness?

What years ar ok for shortening??

[Geary]

'87 & '88 have enough case material for shortening without "bandaid" addition of case alloy.

[doozer]

Wow, I did not know it was limited to two years??

Thanks for the info...

Ok aren't the 87-88 trans a G50and not the regular 4 speed 930?

1989 was the first year of the G50 in the Turbo. The regular 911 got the G50 starting in '87.
