6 speed manual verses 6 speed auto

I maybe missing something, but why, other than for the bragging rights, would anyone but a dedicated racer add more manual or auto gears to a 928? More gears are what small engines with narrow torque bands need. Like the 17 or so speed 125cc Honda racing bikes of the 70's. But with a torquey 928 mated to a 6 speed manual most would use 1, 3 and 5 or 2, 4 and 6 for everyday driving I reckon. And the stock auto seems plenty fine for both strength and purpose. Sure a bit of a gap between 2nd and 3rd but if not working ok why not just fix it / replace it with an oem transmission?
Or simply do it 'cos you can and it's fun and it's a hobby that keeps you sane when stuff gets hard and it's your car and you can do whatever you damn well please. And all power to you.
But I still don't think it's needed in a normal technical sense.
Just my thoughts...

Have you driven a modern car with 6 speed auto? I am not saying everyone should convert their 928 since it is a classics, but for people who want to hotrod their 928, the 6 sp auto is lightyear ahead of the ancient MB unit. Try a MB E350 or a Lexus IS350. My 1987 S4 drives like a brick compare to those.

Good morning all - great replies to my post. Yes, Dinsdale, you're right. I should be 'driving' my car rather than just sitting in it. But you see that's what caused the problem in the 1st place and now I have but one point left on my licence!! One more infringement and I won't even be sitting in it, I'll be on the 'loser cruiser' (i.e. bus).
If I were to make the change I'd go for the 6-speed auto. From a business perspective I also think the auto 3 / 4 speed to auto 6 speed is a bigger market segment. But from a gearbox strength etc perspective I'd think manual 5 speed to manual 6 speed to be more 'necessary'.
Cheers all

Most of the modern 6 speed transmissions feels as if the PCM cuts the throttle between shifts. If this is wrong, I aplologise. I'm guessing this is to smooth the shifts and to reduce the shock on the transmission. If this is the case, how will a transmission react/last with a non throttle by wire engine?

Imo000 , Good question. It would react harshly and would not last long. The auto 6 speed conversion would include a drive by wire throttle and updated engine management. The mechanical end of the automatic conversion was fairly easy. It's the computer interface that's whoopin my *** on this swap. I've been talking [ begging for help] with some enginerd's from Bosch,GM and lotus about this problem. We currently have a team of technicians/ enginerds working on a solution. We will prevail !

Elite Racing Transmissions in the UK builds Sequential Transaxles for all types of cars and builds and i think this one could be adapted to the 928:
TXL300 6S – Trans Axle 6 Speed Sequential
Six speed sequential motorsport gear box with various ratio options available: This gearbox is used in high torque, mid engine, rear wheel drive set up applications such as GT40 builds, kit cars, time attack builds etc
ASequential 6 speed would be pretty awesome in a 928.

What do you guys want?
Do you want a 6 speed manual trans or a 6 speed auto with paddle shift or slap stick?
Piranha Bros has already done the 6 speed manual, now we are in the process of our first 6 speed auto swap. We would like to know what our potential market is so we can design the best product for you all.
Manual or Auto?
PS: What would you guys think is a fair price?

planet would pay that much to install it in a 928.

Go to the their site, 7995 UK,(most expensive unit ) adapter plates and other sundries very reasonable, another grand. Very High Quality stuff, already talking to them will update when they figure something out.
handle 500 lb ft torque, good fit. Beautifully made racing transmissions.
Been around a long time. Have capability to work with you on fitment.
They have in line 6 speed sequentials that handle 550 pound feet for $4995. They do Porsche LSDs
I've been thinking there must be some way to adapt one of their racing transmissions, it's what they do for vintage car owners.
The English are very into Motorsport and Gearbox Manufacture.
You'd feel like Derek Bell in a 962 with one of these installed.
