Last two months of development on DKG conversion. From 3d modeling to production.




















Mechanically need to fabricate connection joint on the driveshaft and it is ready to go. It will be controlled with HTG GCU ( standalone Gearbox Control Unit) which will communicate to the Haltech ECU via CAN bus. BMW M4 shifter will be used both with some steering wheel shifter pads.

 

Gearbox is from M3/M4 F80/F82 model, GS7d36sg. It is good for 700 Nm from factory, but it can hold much much more. Raising oil pressure on clutch packs to a 17 bar and it holds 1000 Nm. After that there are upgrade clutch packs and it will hold even more.

 

That is awesome! How much more expensive and readily available is the DSG? Are you going to going to put paddle shifters on the steering column?

 

This. Is hot rodding/building to a need at its finest!

And not once is it mentioned “Help, my car won’t start!” 😈

Great work!

 

I like it...I like it a lot.

 

Finally chop out that 2nd / false firewall??

 

Actually M3/M4 gearboxes are cheaper and easier to find than 350z gearboxes over here. Bought one with very low mileage (2000 only) for 1400 usd, while 350z gearboxes sales typically for 2000 usd at least.
Yes, I will put paddle shifters on the steering column. HTG GCU can accept virtually every paddle shifter (analog or digital). It can work as a sequential gearbox, on engine start it automatically goes into the neutral, and pulling shifter for target amount of time (software adjustable) it shifts into the first (or reverse). In addition, you can have functional clutch pedal too (e-clutch) for clutch kicks (drifters will love this), by putting 0-5V pot on a clutch pedal.

Thank you Sir for your kind words! But yea, my car won't start at the moment .

Thanks, thanks a lot!

As a matter of fact I will probably, but absolutely not needed for DKG, it fits perfectly without any chassis modification.
However, mid mount turbo doesn't have enough room anymore because DKG gearbox is wider at the bottom, so I'm thinking to move turbo into the engine bay.

 

Some rewiring of gearbox electronic is needed too.

 

So much props!! Cant wait to see this thing in action

 

cool project

 

So for a little bit of money the G/Z can finally have the automatic transmission it has always needed.

 

Yes! Although, it isn't that cheap, but much cheaper than sequential alternatives.

 

I was thinking in the end it would cost 3-4K.
Tranny-1200-1300
Tranny ECU- 1100
I'm thinking adapter would be 700-1200 depending on demand. (If you do sale it.)
Then you need to find a tuner for the tranny. Thats the big X variable but I'm thinking 500-700.

 

Tranny - OK
GCU - OK
Adapter plate, pricing is in a ball park, but you need a new flywheel and flywheel to input shaft adapter too. You could probably modify aftermarket 350Z flywheel (like JWT) and still need FW to input shaft adapter. Also, do not forget driveshaft, you might need a custom made one too. I still believe that OEM carbon can be used. Oh well, soon we will know for sure, probably in a next week or two.

With HTG GCU you will receive base map, so you will be ready for drive, but need fine tune to accommodate your setup. I've looked into the GCU software, there are no too much tables, it should be doable by yourself.

 

Also, there is wiring harness. If you buy it, it cost another 500 or so.

 

You should consider offering this kit when you've completed yours. You already have the files, so why not? Especially if you can pull a 'Plug and Play' kit together. Don't go crazy on mass producing it but.. 30-40% up front (none refundable) and the rest when ready to ship? I would. Customers can source their own f80/82 transmission. They go for about 850-1200 in the US. Compared to a sequential setup, this is definitely a good alternative. This would be savage at the track!

 

I didn't even think of fly wheel or stuff. So well add another $2500 so thats what $7K. Sequential's are what 10k+ I've never looked into them since they don't appear to be that strong until you invest a TON of money into them.

 

Sure thing, why not, already doing 3 kits for local guys. Mechanically it should be pretty much PnP, except driveshaft modification, which shouldn't be difficult if all goes as planned.
Not Z, but DKG with HTG GCU in action:

Not that much, for small series like 5 to 10 kits I would expect more like $4-5K plus DKG. Yes, sequential gearboxes are expensive, weak and having short maintenance intervals, which are again expensive.

 

This transmission would be brilliant for a circuit Z, I hate manuals.

 

i hate you
