APS Stage III car fited with T56 6 speed

[cuspub]

Frank if they use the Getrag it will make the T56 look and feel prehistoric........the Getrag is standard in the Nissan GTR 33/34 and the Toyota TT supra and BMW M5.

The Supra has been drag raced on slick tyres in the states for a decade at Torque levels far in excess of curently modified T engines.............this transmission is a work of art...........virtually industructible............and this is one quick shifting manual trans...........unlike the T56. :lol:

Nizpro, I guess like everyone involved in supplying parts for the XR6 Turbo, has investigated a myriad of alternatives as far as both manual and auto transmissions is concerned. I mean, when selling a product that increases torque output (Noting that toque is how transmissions are rated, not horsepower) to in excess of 800Nm, you are or can potentially be faced with a hand granade.

So we all start looking around at the various options from that used in the Supra, yada yada. At the end of the day we all simply want something that holds together under duress, and from what I have been able to decipher, the Mal Wood conversion has worked well behind Bcl's engine (which I would say is delivering closer to 850Nm).

The Getrag used by BMW for their awesome M5 is Model 226, a 'box that is rated by Getrag as their strongest of the series, however it is rated at 'to 500Nm', which I would have to say is a very long way from the 800 + NM produced by the Nizpro Stage 3.

This being the case Peter, why do you think it would be a better option than the T56? (besides shift quality).

Peter - thanks for that... I think.  :lol:

Perhaps my brain isn't firing today, but I still don't get it.

Is that a typo or are you saying you have the T5 (OEM) box in one of your cars, yet its been reported in various places as having a 6 speed box fitted. Not only that, but the guy who bolts the modded T56s together recognised it firsthand - fitted to the car. Surely if that was false, you would have cleared it up earlier?

I won't discuss all of the engineering parts that have been fitted and tested in the APS XR6T over the last 20 months, though let me make this crystal clear for you guys,the APS XR6T HAS a 5 speed manual T5 transmission and this is not a TYPO. :lol:

Thanks

I'm sorry folks, I neglected to add the URL pertaining to Getrag's specifications.

:lol: Greg that's easy to answer, the Getrag is easily the better gear box (in fact this is not even a sensible comparison).The T56 versions being used in the Holdens and by Mal is rated to approx 540Nm.

Now which do you think is the better trans...........the magnificant German built Getrag or the mexican built T56? :lol:

Now the M5 Getrag is rated for 500 Nm and M5 weighs in excess of 1800 Kg, the XR6T weighs around 1670 kG......... so the Getrag would easily cope with the Torque far better than the T56 currently being used by Mal which is rated for approx 540Nm. :lol:

To finish I was not suggesting that the specific Getrag in the M5 was the trans that Ford.......... or APS would utilise in the XR6T.

Peter, I appreciate that the specific Getrag mentioned as fitted to the M5 may not be your choice, however it is – as far as I can decipher – the strongest RWD transmission available from the Getrag stable. The alternative I suppose could be that recommended for the Nissan Skyline GTR, Toyota Supra, and Supra Turbo, the 233, however it is only rated at 490Nm.

Model 448 appears to be the strongest in the Getrag range, suffice to say it is a transaxle type and with 540Nm rating is supplied for the Porsche Turbo and GT3 (amongst others).

I didn’t realise it wasn’t a sensible comparison between the T56 and Getrag, certainly given that the same T56 is used in the US on cars weighing in excess of 1800kgs.

But okay, if this is the case, which model Getrag are you considering?

I will of course understand if you won’t tell me for commercial reasons.

Finally, I know it’s not my place, but having read the other posts about you running the Mal Wood trans in your car at Queensland, I am quite interested to know how it held up. I ask because of the success Bcl has been having with his, and was wondering whether you were as happy with it as Brian?

Cheers.

Peter, excellent.. thanks for clearing that up. My brain might not be firing much this arvo, but its firing enough to notice not only what you have said, but what you haven't. Why you don't want to say that it *had* a T56 in it is not really my business I guess, but its certainly makes for entertaining reading :lol:

You obviously have your reasons for preferring the Getrag over the T56 and we may never know what they are. Suffice to say that your reasoning that a 500Nm rated gearbox should easily be stronger than one rated 540Nm defies any logic that I can rub together - the weight of the vehicle is irrelevant (as both boxes are pushing it albeit one is rated stronger than the other).

Greg as a matter of interest what specific CAR is this model T56 trans utilised in.......... that weighs over 1800 kG.

There are over 20 specific tremac gearbox models and certainly some of the T56 gearboxes are rated for very high Torque...........though the T56 trans we are discussing here (what Mal uses is rated for 540 Nm and is out of a mid weight car)is rated for 540Nm and is out of a car weighing much less than 1800 KG.

No your missing the point............the Torque rating of the gearbox which is specified by the OEM manufacturer and it's drive train engineers (in this case BMW) is relevant to both engine torque and the vehicle mass.

Well I must be mistaken then.

Reading the company info - the unit has a single rating, yet is fitted to vehicles ranging from the M3 to the 540i. I would have thought they tipped the scales somewhat differently.

The T56 versions being used in the Holdens and by Mal is rated to approx 540Nm....

NO T56 is rated at 540Nm, they are all either higher or lower. The six different versions used by Expensive Daewoo have all been rated at 474Nm. Our std box is rated at 610Nm. Ben.
