Sequential shifter

[porsche 930twin]

Hi all just enquiring if anyone has or knows of a sequential shifter system for a G50 transmission.... I am after something a little different then the ones on offer...

That shifter would be worth every penny. I did the money shift going from near redline in 3rd to 2nd instead of 4th.

From what I have seen, the cable set ups would not fit between my torsion tube and the box. I would assume that a sequential linkage would be similar.

Sequential shifting via steering wheel paddles is becoming a popular conversion on Tiptronic 964's. I'm not aware of any conversion for 930/G50 transmissions.

having worked on a lot of Motorcycle transmissions and Porsche transmissions

you would have to change the the whole trans or guts or change from syncros to dogs in order to get

True instant shift with cut of the ignition -

Don't the Cup GT3's pre-PDK have sequential shifters?

And up-shifting without clutching, too (you were probably talking about that). Probably not much use for that technique on the street, but for the track, super fun and useful. I roadraced motorcycles for 10 years, was scared to do clutchless up-shifting at first, but once I tried it, there was no going back.

A sequential shift transmission conversion is something I would do if I had the bookoo resources of some that post here - really luvs me some of that!

and the POP every shift is way Cool

I am using this sequential system by SQS on my 996gt2 turbo Trans.
It does require the clutch, which saves wear+tear on the syncros , etc.
Shifting is now linear movement on the stick : forward or back
Check SQS website for 930 Trans compatability.

have the SQS shifTer on my GT3 CLUBSPORT BRILLIANT

Sequentials are amazing. The H pattern has got to be the most time and energy wasting method of shifting ever. (Don't harrass me for not being a purist, I'm just being realistic. I've been H shifting for 45 years, and have raced with traditional Porsche transaxles, Hewlands, and Top Loaders).

Creds.......you have 'em.

The old 930 transaxle synchro units are too slow acting for a sequential shifter. It would kill them.
Borg Warner synchro units in the G50 are much faster acting.

The SQS shifter is brutal even on the G50/G96 synchros. On cars with them installed we see them needing service much more quickly. All of us can already shift faster than the synchros can synchronize. The sequential shifters make that every more of an issue.

We have done both the 930 and the G50 gearboxes as dogboxes, but left them as an h-pattern. The G50/20 6spd was the first one we did as a true sequential. Eventually that gearbox evolved into what is today the GT3 Cup Car sequential in the 997 chassis cars form 2005-1013.
