To what 01E boxes are you all referring?
The boxes used in the Audi's or 968's?

They are talking about the audi box. Its supposed to be pretty strong too. The 968 transmission is just too rare and expensive.

On that note, looks like I'll be in the market for either a turbo transmission or finding some way to beef up my NA trans to take some abuse.... And the only option I've heard of is to machine the housing and install a billet steel spacer plate to replace the weak cast steel portion for the pinion bearing, which, I guess is an okay idea to support a future 5 cylinder turbo build, however I haven't been able to find documentation on the limits of that modification.

I have driven the open differential n/a trans and you definitely want lsd with anything over 180 hp I would say. Turbo s transmissions are a good deal if you plan on launching your car due to the first 2 gears being hardened compared to the turbo or s2 transmission. If your road racing not spending much time in 1st or 2nd gear both the s2 and turbo should be as strong as the turbo s. The S2 transmission is geared for n/a applications but if you change the ring and pinion to a turbo one I believe, all your gear ratios become the same as the turbo transmission + - 1-5% in all gears.

s2 is the cheapest transmission to buy that can be converted to turbo gearing or remain in n/a gearing and should be as strong as a turbo s transmission from gears 3-5.

if your drag racing on slicks the aparent limit of the turbo s transmission is 425 foot pounds of torque. Apparently this is the limit where the stock chassis bends too. If on street tires or track tires apparently a guy has had his transmission live at 700hp for 2 years until he replaced it so he could have paddle shifters. I have no proof of this i just read this on another forum

Dont Quote me on all of this but this is what i learned from research when choosing what transmission to put into my 1983 n/a 944

I think a lot of people are going to need a new trans . The current stock NA tune on the PE ECU will have you at the 190rwhp range .

how are the ECUs coming? Shipping out soon?

I would love to see what these engines can do both n/a and turbo with new cams and springs to raise the rev limit to from 7000 to 8500rpm

Hey mike, so i am also running Audi box, though not an 01E, i chose the different cheaper rout of running an 01X. for my diesel build. perfect gearing.. and tons of options, i might test the waters with an 01E later on, as now that i have it adapted to my car its pretty much a bolt in swap from my 01X. which is basically a 6 speed boxster s box/ or audi 3.0... mine is out of a 2.0l TDi from europe though.

i made my own adaptors and custom crossmember but could easily be adapted to the stock bar etc,

im willing to share some info if needed, as i got my info from i believe the first guy mentioned... NOT WIDERSTANFEIGDKJGH...

he started talking about his sway kits.. they werent cheap... in my opinion... i think he wanted something like 350 for the coupler which wasnt a great design in my opinion and his trans adaptor(mount) was like another 300,,, for a piece of steel...

Okay, so dipped my toes into the 01E rabbit hole a bit and was intimidated by just how much content there was, so perhaps I ask here...

Is there such thing as a DSG 2WD 01E transaxle?

A "944 if they had paddles back then" restomod could be cool... Perhaps too ambitious with no existing literature, but somebody has to be the first, right?

I already thought about this . If you have deep enough pockets ,, the PDK from the Porsche Cayman would be a possible choice .

I think the residing issue is that the 01e swap has been 100% custom, and no one steadily produces the components needed to put it into a 944 chassis. There's also a supply issue for the trans itself, so we'd have to either import them, or find a used one and rebuild it, which is the track I'd be taking since I know a friend who has one with syncro issues.. if I had the capital I would invest in the machines needed to do it myself in a heartbeat.... But until then I guess us NA guys are restricted to a safe power level. gg Porsche.

Edit: that being said, my NA has a 40% LSD diff, & when the stock engine was running I definitely wasn't very nice to it, so I'm not too worried about my driving style being impeded, it would just be nice to have reassurance and peace of mind someday.

The market is obviously begging for a solution. Some day we will investigate it further and hopefully come up with something for everyone. Unfortunately we just don’t have time right now with all
of our other commitments.

It's a shame that the swap kit that projectnine was working on was never made commercially available. I was looking forward to purchasing one when I saw their posts about the SEMA build. Also to jump on what dmnted said, which you might've missed a few posts up... any updates? Just curious to know whats been going on with the harnesses and ecu development/production. Any news is good news, as long as it isn't about one of Alan's pistons visiting the ISS

And if so, I would like to request on behalf of the thread: video evidence with power numbers and supporting data
