I Finally found custom gears and r&p for the 968 tranny!
I've been away for a while, I know. It's because I broke second gear in my tranny on the street taking out some modded whatever. It's been so long I don't remember anymore. Broke my tranny and still took him. Anyway, that was about 4 years ago.
I REFUSE to pay 911 prices for 951 parts. I've spoken EXTENSIVELY with Eric at Carquip, and Roger at CMS, since he AND Eric were at PowerhausII. A long time. I have finally found an economical solution.
Scott Dewitt. A mechanical engineer who owns and operates Advanced Automotion in Corpus Chriti Texas builds extremely strong Audi O1E Gearboxes for Audi's putting down 800whp + cars for a while now. I met him personally, knows his Audi's and lucky for us, I've got him to not only rebuild my tranny, but I've convinced him to get into the 951/968 game.
Prices are way cheaper than both before mentioned places
In the past, if you wanted a custom ring and pinion, at least ten of us had to put an order into Abins down under, wait 3 months, and pay out the nose. North of $3500
Right now, If you guys with bigger hp want to go with a ring and pinion for the 968 box, he can get a 3.4, like the Turbo S or a 3.1, for even better time spent in your power band. It depends on how many orders he gets for each. And they're made locally for a company in the middle of nowhere in Texas who makes gears for race teams. So we'll get them quick.
MOST IMPORTANTLY, WE CAN BUY THEM FOR $1800!!!!!!!!!!!!!!!!!!!!!!!!!
All I've done for the past 4 years is research on which tranny to go with. The 968 is stronger. Period.
you can get more parts for it. Which makes it cheaper.
My order is already to go. Looking to see if enough Porsche guys order the 3.4 or the GTM guys running the Factory Five Racing all american supercar are going to place enough orders for the 3.1. I'm in for either.
I've been working with this guy for over two years now. I've met him and we spoke in depth. the prices people want to charge us for parts for our cars is ridiculous. If I wanted to do that, I'd already have a 997T. Stupid. So, I've managed to make a deal with this guy. Wait till you see this tranny. I'm going to jump as soon as he gets enough orders in. With my power and future upgrades, I need a bigger ring and pinion. But if it doesn't happen, I'm still going to get custom 4-6 gear sets. And it's going to be cheaper than all the others that try to over price our parts. No thanks.

Joe, don't get me wrong. I could be into this. I just want to wait to get the dyno charts back and then decide what looks the best combination. For a track oriented car I have to be careful and not go for gearing that will induce too much of a rpm drop after each shift.
Thanks for following this all up and posting.

This looks very interesting, very promising. I don't know whether I'm going to stick with stock gearing after my turbo project, only way (that I trust) to find out whether the stock gearing still works for me is to actually drive it, on the street and the track. No amount of calculating and number crunching will answer that to my satisfaction. But once I've completed the project and driven it enough, if I decide that I want to go taller, this sounds like the perfect way to do it, and $1800 sounds quite reasonable.

Mr. Defastest....
i have been looking to do the same for my spare transmission box for some time...... in early December i too, discovered Scott's shop as i was looking for a conformation that the 5th and 6th gears i had sourced from a 01e would fit my 968 transmission.... he had already done most of the research, and set a few matters straight, (including that my ambitious purchase was indeed, a NO GO). however, he was helpful in explaining that the gears from the 2wd diesel box (europe) would be the correct box to source either new or used gears..... then he was nice enough to offer to buy the other 01e S4 parts from me. and i posted about it back in December on my car's thread:
968 stock 6 speed manual:
1st; 3.182 :1
2nd; 2.000 :1
3rd; 1.435 :1
4th; 1.111 :1
5th; 0.912 :1
6th. 0.778 :1
final ratio 3.778
968 Turbo S 6 speed manual: with help from Raj:
1st; 3.182 :1
2nd; 2.000 :1
3rd; 1.435 :1
4th; 1.111 :1
5th; 0.882 :1
6th; 0.711 :1
final ratio; 3.455
your idea of a better rear ratio does one thing that our "other solution" doesn't do: making gears 1-4 more taller and more useful for all that horsepower you have on board. one more reason why the 968 Turbo S rear ratio makes a better gearbox. i found a less-effetive solution of just swapping out 5th and 6th gears to be good enough for my needs.
i imagine you already know that the 968 Turbo S box has the taller final drive, but also has taller 5th and 6th gears. on page 4 of my thread i did a few calculations on gear changes (from normal to spirited driving to racing) with the new ratios: see post # 49.

one of the most difficult parts to source is the correct transmission for high top end at 300+ horsepower... Porsche sold the last 968 Turbo S transmission for the street with 180 mph 6th gears a few years ago. i've been researching for some time how to set 968 transmissions up for more top end without breaking the bank.... first, i sourced a spare transmission with low miles, so the first problem was solved...
at the time i was under the assumption that any and all Audi 01e 5th and 6th gearsets were interchangable with the 968. apparently, not so... Scott at Advanced Automotion set the matter straight.
everyone seems to overlook 5th gear. the stock 968 5th is way too low for 40-55 mph on the secondary roads without beating up the LS motor. 5th and 6th gear swapping:
as it turns out, the 968 guys are stuck with either having maybe, like a .810 gearset made, or running the stock 5th .912 gear (which is too low), or running a .729 5th gear available from the (Audi A4 01e box, FPN FRL) which drops the rpm down somewhat lower than would be ideal after coming out of the crappy, stock 4th gear, but this is what i will run.
the .729 5th will make about 160 mph @ 6,000 rpm (running a 25.6 inch tire).... the .600 6th gear will make 195 mph @ 6,000 rpm, or about 188 mph running a 25 inch tire... and the gearsets will bolt right into a 968 box.... a .680 is also available making a perfect top gear for turbo and supercharged 968s.

Standard heat treatment processes, which is harder than factory.
Pricing in this business is never firm, they go up and down (mostly up), so any price quoted is not set in stone until the gear grinders are fired up.
A lot of developments have transpired since me and Joe talked in depth about a ring and pinion, namely that the ring and pinions from the Audi 01E to Porsche 01E box are the same, which they aren't, meaning the possible market for this is exclusive to the Porsche 01E crowd which is much smaller market than the mid engine conversion people using the Audi 01E.
Also the dollar has deprecated significantly over the past several months meaning higher prices since some of this stuff is source overseas, and oil has gone up meaning freight costs have gone up as well.
However I did find a Porsche Motorsports ring and pinion supplier who will make 5 for 4500 euro each which is almost $7000 usd each!

yes, indeed. but, me already has a 968. not a 951. i also fixed the post to specify that i was talking about the extremely rare, 968 Turbo S box.
sorry for not making that clear.

Wait, now I'm confused. I'll have to get on the phone with Scott again. I was told $1800 for a ring and pinion. That was from a local Texas manufacturer. Call me if you read this Scott

Joe, what is wrong with the 951 turbo tranny? What are you trying to get out of the 6 speed that you cant achieve with the 5 speed? Im curious because I am having a full tilt 3 liter built and the only thing that I have not changed is the tranny because I thought with the 6 speed I would be shifting all the time.

Blitz, i would want the 968 box if it could handle more torque than the '44 box. but you also have more gears to stay in peak power all the way to 190 mph. problem for Joe is that after getting the taller ring and pinion, he STILL needs to install the taller 5th and 6th gears to go really fast. i'm doing that without touching the ring and pinion such that gears 1-4 stay all stock, and then dealing with the inconvenience of a lot of the huge rpm drop after changing from 4th to 5th.
for more top end on a shorter pavement, like the (texas mile), then you want something close to the stock 5th and 6th of the Turbo S box. for me, i just wish to reach 190 during a single, long pass of about 6~8 miles.
