915 transaxle question / info, a silly question... Options

[CCSmith58]

Hello 914world… Just renewed my Membership !! Now looking to get my moneys worth...

I’m having a ’75 914 built into a 914-6.
Maybe 10 or 20 years ago I might have tried to do (some of) it myself.
Now I’m more a “pay the money, turn the key” guy.
Here’s a “silly” question. Likely the first of many….
How does a 915 Transaxle work when converted to a mid engine application ??
Not looking for a “how to” just an overview for personal info.
I’ve searched for articles, webpages and / or videos and don't find much.
I find acknowledgements of the conversion but no detailed or even general description.
I see the term “flipped ring and pinion”.
Does the whole gear system run backwards ??
Does just the differential run backwards ??
How would a LSD work in a converted 915 ??
Are the available 916 Kits good ??
Etc...
Any info or links to info would be appreciated !!

My 914 build is "in process" although still a year out... (IMG:style_emoticons/default/wacko.gif)
I've already bought the '95 993 3.6 and a rebuilt / beefed up 915 transaxle.
The 915 was being built to use in a 400hp 911.
The Gentleman I bought it from decided to go to a G50 unit.
PMB is building the car.
I'm just trying to educate myself about crazy alterations and conversions all you 914ers
have been dreaming up and perfecting.

DD, thanks for your post. That's the kind of info i'm looking for...

So, How do you "flip" the ring gear ?? Do you replace the pinion shaft (gear) ??
Would an OS Giken lsd work in the 914 application ??
Again not looking for a how to, just info...

No need to replace any of the major parts. You literally pull out the pinion shaft, grab the ring gear and associated bits, and run them around so they are on the other side of the pinion gear. In the pic I posted, just imagine the "differential carrier/ring gear" part flipped around so that what was toward the top of the image is now toward the bottom of the image, and what was toward the bottom of the image is now toward the top.

Of course, there has to be room for the assembly on the other side of the housing that it lives in. And that's where some of the work comes in, because some trans designs don't really have room for it that way.
