I am trying to get my schedule to match, I'd say right now it is 80% probable that I will be. I think they moved the show up a week early. Planning on attending?
I came across this thread after a search for pictures for sunroof alignment of all things .
i saw this image below, posted about it, then Rob Edwards replied with the link here. Just spent the morning reading all 57 pages.
Just amazing....And more so as its done with no blankets or covers over the car protecting that paint. my car is an cocoon of covers and plastic while I put it back together. In the end I always get some “hangar rash” no matter how careful i am though.
Captain Obvious here ....but...the amount of focus and drive in this project is off the charts....so glad it is on a 928. And more so that carl takes the time to take pictures, document and share what he is doing. Thats the true gift.
Fascinating project and exactly what I want to do to a 928. Unfortunately I don't think I have the patience to do all that Carl has accomplished. However I do intend to utilise the same engine and transmission as Carl, specifically an LS3 with 6L80E and have a couple of questions I was hoping Carl or anyone else could answer.
What Torque Tube are you using and what modifications were required?
Does the modified rear crossmember come from 928 motorsports and does it suit the 6L80 transmission and/or what mods were required?
What engine ECU are you using and does that interface directly to the transmission controller (internal in the 6L80E I believe)?
Presumably the OEM 928 ECU becomes redundant, or is it still required to control other parts of the car?

Talk about a delayed response, my apologies both to you and Tony for not seeing these posts sooner. But as they say, life happened and took all my free time....
The plan was to use the torque tube from the automatic Corvette equipped with the LS3 style engine. Can't remember the exact years they were produced but 2013 was one of those years I recall.
The torque tube and transmission was test fitted and fits, when paired to the LS3 mockup block. Torque tube just needs to have the wire harness tabs cut (shortened) to fit in the torque tube tunnel. The rear area where the rear bell housing sits would need some slight massaging where the mounting ears are located.
The 6-speed automatic would need the stock mounting ears removed (cut off) and a modified rear cross-member (like the 928 Motorsports one).
The ECU would have been the stock GM ECU for the LS3, and the stock transmission harness.
That WAS the plan, and I am certain it would have worked fine. However due an extreme work schedule and other projects (JP) my project has been sitting idle for a very long time so no work has been done on the 6-speed conversion. Technology and options have also evolved, so changes to the plan have occurred
Now that JP is about to leave for her new home, and my move westward to Arizona will commence later this month, I will begin working on my project again later this summer. Pictures to follow, right now we are busy packing up the house and cleaning out 18 years of storage....

If I'm not mistaken, that's a Tesla Large Drive Unit sitting under the back of that S4. What's the plan there? That is my other project I've been thinking about as I reckon it would fit in place of the rear transaxle. Tell me more.
Thanks for the response though. I'm just rather more excited by the Tesla project currently.
Carl, I think you should work with Tuomo on the Corvette transmission install. The Twin Turbo 928 terrorizing the street has way too much torque for the standard gearbox. https://rennlist.com/forums/928-foru...reets-174.html

It is a 1:1 scale 3D printed version of the large Tesla unit. Stock power is around 450 HP, with the sport version going up to over 560 HP. Yes it fits very well once the gas tank is removed. The battery box needs some trimming but it is huge and very deep, so there is plenty of room still for a 12V Lithium accessory battery.
Having been driving a Tesla for the last 4 years made me realize there is no way I am going to put a gas engine back into this 928 project. No oil changes, no maintenance, no drips or leaks. All sealed systems, just get in and go for a drive. "Fill up" at home, always walk out to a "full tank" every day if required.
The swap technology for these conversions has come a long way so I will utilize one of several companies out west, a couple in CA and one in AZ. Haven't discussed the details with them yet.
But I'd say that is the direction I'm taking this project. In addition, Tucson AZ is an emissions city, so the only way to do the Corvette conversion would be to have 4 catalytic converters installed which there simply isn't enough room for in order to make it neat. More cities and states will eventually have to follow the CARB requirements, so this will make it future proof in that regard.
I know some folks will be pulling their hair out and have a cow, but that's OK, it's not going to be for everyone. I for one prefer the instant torque and insanely quick acceleration in near silence
The non-drivetrain modifications such as electrical etc can be utilized in any 928 so that information might come in handy for some folks down the road.

Hej Åke!
Does he need a Corvette transmission or is he working on a stronger transmission for his twin turbo? I seem to recall someone in the UK made a custom high strength sequential gearbox for the 928 but can't remember the user name, Perhaps that would solve Tuomo's dilemma? If he needs a 6-speed auto and torque tube, I'd be happy to let go of mine at a inexpensive price
Hej Carl,
I do not really know of Tuomo´s plans. He has mentioned going from the 5-speed to an automatic transmission.
Best if you contact him directly - I have PM you the email address.
Why buy a Tesla? Should one not wait until the real car manufacturers get their models on the market? I have said when someone (prefer Porsche) can offer a minimum of 1000 hp, a range exceeding 1000 km and a top speed not electronically limited, I may be interested.
Happy summer.

Thanks, I will send him a note.
Why buy an Audi? Or Porsche or BMW? Why not a Tesla, if it has proven to be superior in ownership, performance, reliability and cost of ownership and maintenance? In my 52 years, I have never owned a better car, subjective opinion, sure, but nevertheless that has been my experience. I have owned BMWs, Audis, Porsches, VWs, Twin Turbo Nissans, etc, and none of them came close. Every BMW and Audi spent more time at the dealership than my Tesla has. None of them had better acceleration, passing capacity or cargo capacity. I can fit more stuff in my Model S than I could in my Audi Allroad (Station wagon). My Tesla handles better than my BMW 530i M-Package did.
What people seem to get hung up over is range anxiety....and sure in a Nissan Leaf or Chevy Bolt with their substandard charging networks it is an issue. Not so for the Tesla. There are charging stations everywhere basically. In 4 years of ownership I have not had to settle or alter my routines in anyway. I drive it exactly the same as did all my other cars. In fact, every morning my "tank is full" if I desire it to be, without having to go somewhere first to fill up. All for a monthly cost of $35, compared to $120-$150 a month in gas. In 4 years the maintenance has been a cabin filter and a brake flush for a total of $280...
As far as the 1000 Km (621 miles) of range wish, who wants to drive for almost 9 hours without stopping (70mph)? I sure don't. At my age, 3-4 hours is as long as I want to drive before stretching my legs and getting some food or coffee. Younger ages may vary....and the 2021 Model S has over 400 miles of range, which should arrive in my garage next month I hope
Carl, this is not the right forum for us to discuss electric cars.
Do not tell me to buy an Audi, I cannot imagine that, it is out of my world.
I have enough cars for the rest of my life, I will not buy any more cars, at least an electric car that does not have an internal combustion engine to work on.
Well, we drove a trip of about 700 km the other day down to the west coast of Sweden as we have some graves down there to take care of. I did not see any charging stations down there in the villages and small roads by the sea.
I do not think you drive an electric car to save money, it must be something else. I can buy plenty of petrol for the price of a Tesla.
As I spend most of my time in the workshop I am not consuming much gas so I am almost a green guy.
I'm really looking forward that you will complete your 928 project, it would be fun to follow.

IMO, an electric 928 would definitely be a cool car!
Have been quoted $25K for rebuilding my GTS motor. Could I go electric for that?
My apologies for a super late reply. Figure around $8Kfor a drive unit,and controller box, a 928 Motorsports rear cross member (or similar setup) and some minor welding on that cross member and rear body to install the mounting ears/brackets for the drive unit. Add cost for a couple of custom drive shafts. Don't have a price on a battery pack as that would depend on what size (Kwh) you want and what type of pack modules (Tesla, LG etc).
EV West, Mountain Pass Performance, HSR Motors etc all have drive units and battery modules for sale. And most do conversions as well. I'm guessing yes, the cost of a GTS motor rebuild would get you in the ballpark if you do some or most of the work yourself. If you have to farm out the labor I'm guessing a bit higher.

my car is an cocoon of covers and plastic while I put it back together. In the end I always get some “hangar rash” no matter how careful i am though.
