not interested in swapping... I want to keep my carrera GT original & i really like the dog leg 1st layout.
spending a small fortune on it at the moment...  but the car is worth it!

Yeah. But it's how often you have to replace the bastards!

Pez,
speak to a company called Hollinger Engineering, in Australia (Google it) They are a transmission specialist, and make the GT3 sequential boxes. They might know what would be involved in getting these made/modified to suit.

I never said that I want to use 930 box in 931, I'm not that stupid not to understand that they're not interchangeable.
As for G50, you should have your information updated, because 930 gearbox is one of the strongest Porsche ever produced for street cars.
G50's only advantages are that it has shorter gearing and better shifting= better for racing.
And as for drag-racing, no, if gearbox can withstand 1 hour race, IT DOESN'T mean that it can hold together hard launches. It's obvious that you have less dragracing experience than circuit racing. And I'm not saying that you have little or something. Just sometimes THE GREAT WAYNE doesn't know everything.
You should bring some hard facts and statements rather insulting me (btw, you're great at it too, insulting people). |
Haa, haa, the great raceboy!
let me say it more slowly
G50/50 race boy , better than 930 trans,
also you brought up the 930 gearbox i did not .
A trans will handle drag racing easier than full power for 1 hr and i repeat that most of the damage drag racing is caused by the tire and clutch shock and you are right i have only been involved with 18 or 19 different drag racing customers over the years so i'm rather limited there 
i'm not so sure i'm in your league, when it comes to insulting as you level a serious whallop when you are ready. 
Bring hard facts raceboy, i made myself clear in the last 2 post , take it as it is, but remember regardless of the situation, i'm always right , even when i'm wrong

PEZ, try PowerHaus they might have the gears you are looking for .

Yes, that's what I was trying to say. And I think that is the main problem of yours. You should sometimes open your eyes, it may come in handy and not just get stuck in one place (=opinion). I personally consider your statement purely as an opinion (951 box vs G31) because you gave me no serious proof.
The fact that you have raced it for xxx years and nothing happened yet doesn't prove anything.

Look that was a joke, i'm never wrong ! 
i do not know how much more proof you need for the obvious , but i will make it easier for you , go to porsche AG and have them provide you with the proof you crave as to why they switch from G31 to 951 audi box and then i will give you mine, this is about as big as my eyes can get
But instead of throwing all this Negative stuff around i would be interested in seeing your proof and i guess everone else here too, who is tried of repairing the g31, 
I can understand Pez` wanting to repair his box if he has a 924 carrera, etc, so as to maintain the originality of the car in the way he wants .

Sequential, Porsche swapped the transmissions mostly for the cost. Why produce a box, that has more potential than the car needs and have problematic syncros when there was an Audi box that they could just buy cheap? Most of the things manufacturers are doing is just to cut costs, didn't that ever occur to you? And even Porsche does this.
And I've seen a drag-car (not Porsche though) with 400+hp and G31 box, that holds up very well.

one question I have,
if the 951 unit was SOOOOOO great why would they not have used it in the 928?
The G31 was imo a much better box for racing but maybe not for the street use.
and if the 951 unit was really that great, why did the CGT, or GTS not get it to start with? And what unit did the GTR get?

Personally speaking im a fan of the dogleg box.I like the shift patten more than the audi based units. unfortunaly of the 6 boxes ive tried over the years only one has been semi-respectable with only early syncro wear making shifting from 1st to 2nd and back again only possible at slowish speeds. i opted for the audi conversion route. i dont know for sure whether the GT got LSD as standard but i would be loathed to downgade to a non LSD equipped audi box.
As for the strengh,at 220bhp who gives a fu*K? all the options available will handle this sort of power whether its 944,931,944S,951 ect....
For a conversion to the audi setup,its purely a bolt on affair.but bear in mind that the fuel tank will have to be swapped out too.Incedently,all my 932's have had the 937 part # fuel tanks and are not audi compatable.
The CGT is a rare classic and as such it would be nice to maintain its originality,having said that to source all the parts nessassary including an LSD audi unit might well be the best way to go but only if you are carrying out all the work yourself. |

1. I will say it again, the box will holdup better for drag racing , than 1 hr at sebring.
2. Yes the audi box was used because of cost , the god damn cost of constantly repairing the porsche box, was putting everyone out of buss.
3. CGT, GTR, etc made way less power than later 944 gtr in trans-am which ran with Audi gearbox by the factory.
4. I can't comment on the 928 decision making , but there was and is no 928 race car. I have never work with or on one so i have no knowledge of it's potential on the track. i just know from talking to works people it was
not viable.
5. The GTR are cars that i have worked with in the past ( 2 yrs ago the last time ) and while i have written details on the mechanicals , i have never committed them to memory that of the gearbox, but i can say it is way different from standard box, But the biggest issues are reliabilty of the engine which it very rarely finish's a race when run in it's original setup. I have worked on 2 conversions to 951 motors with efi while the original stuff go into boxes
to preserve the setup. I was there to see the original cars run back in the early eighties , i have always loved the cars , but understand the fragility of the 931 all too well in it's original setup. 951 box does not have the better shift pattern , does not shift as well ( none of them does ) but is the stronger more reliable gearbox, if you are going racing at today's competitive power levels and choose to use a CGT gearbox you will change after the 3rd or so race.
the 951 box shifts a lot better with a good shift kit and solid mounts and will hold 600 plus HP ( with cooler ) for 3 hrs plus , i know , we have been there done that.
As i'm typing this , i have to ship out another conversion efi setup for a factory GTR that has gone over to 951 engine and trans ( have to beat that brumos car ) to be faster and more reliable for the 3 hr races .

Still waiting for hard proof as to the superiority of CGT box raceboy, what proof do you have that the 951 box is weaker.
