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 !!

Good point from Steve:
"I switched to the latest 915 trans because the 914 trans drove me up the wall with my 3.2 motor on the street. I felt like I was shifting all the time. Because my 915 gearing was designed for the 3.2, all the gears are taller and now its like driving a stock 911. It’s also much nicer on the freeway."

My car has 245-45-16 Toyo RA1 all around and is turning 3000 rpm to make 60 mph so it is not optimal for long trips, but it suits my purposes of a once per month C&C or canyon drive. This is with an AFNSY gear set. Using a ZD top gear can get me to 70 mph at 3000 rpm with this size tire. My track tire used to be a Hoosier 274-45-16 which was a little bit taller.
