Hi all

Couple of questions really.

1) is the 944 gear box any good??
2) any good online resources for info on ratios, power handling etc?
3) possible to connect to a 2ltr duratec ST150?

cheers tilly

Isn't the 944 gearbox at the rear of the car?

yeh its a transaxle, in the 944 its driven from a front engine and in the 924 its a conventional longitudinally mounted mid engine but most of the gear box is behind the drive shafts

I thought all the 924/944/928/968 etc etc used a F/R transaxle layout. Pretty sure none were M/R?

As Leggyboy says, 924, 944, 968 are all front engine, rear gearbox. Not sure about the 928.

Drive from the engine is via an engine speed prop shaft within a torque tube.

I think you would need to shorten the torque tube to be able to use the bell housing which is at the engine end.

Of course, you could adapt other bell housings to fit the torque tube. However, some of the Audi engines fit the Porsche bell housing including some of the 5 cylinder ones.

I reckon that even with a shortened torque tube the combined engine and gearbox would still be too long to be a practical solution.

With regard to power. The turbo made good power for its day without any transmission problems. The race cars made silly power, but not sure if they used uprated box's.

928 is also transaxle, ZF 5 speed or merc auto, very powerful v8's for the day 320bhp for 5litre but you want to junk the bosche injection.

you are right about the 924 sorry, i was planning something more like this




it apears that the front of the gearbox is a 2 peice bell housing and once yo take the front off its a convectional transaxle

^^^^^
think that is actually a audi 5000 box but it appears to be very similar to the 944 box

yeah , theyre a conventional transaxle , which you 'could' bolt an engine too .

if you have a 944 engine , why would you bolt a duratec engine too it ?

^

Im currently in the opposite situation, i have the duratec and want a transaxle for it without it costing the earth, i have a facility to make an adapter plate, my plan was if its possible to use the original 944 clutch then manufacture an adapter plate and flywheel to suit.

audi transaxle not suitable? used on most of their range, should be cheap enough from a breakers i would have thought and a range of ratios as they have 4 cyl diesels and petrols to big V6/V8s to choose from

just been looking it up i had no idea that audi mounted there FWD longitudinally with a transaxle, i just assumed they were transverse like ford..... ooohhh this opens up a whole new world of possibility

Im currently looking at the VW passat boxes, the devil fuel ones are quite high geared since they only rev to about 5K,

Problem is finding the gear ratios from the box codes, found a big table of codes, about 100 codes with ratios but iv only found two boxes with matching codes lol

audis will almost ceratinly use larger rolling radius tyres than you intend to use though, so often the gearings not as far out as youd think.
