necessary for a custom-made driveshaft?

[sweettom]

HI!

 

 

I'ld have a important question , cause bougth a w58 gearbox with driveshaft and diffusor(A01B) etc., and thought what should do if i want to keep my TT diff(A02B). Is that possible need a custom-made driveshaft or i can solve with the TT driveshaft to fit? I know TT diffusor bigger than NA diff and hold more torque. Thanks for your help.

I would imagine that the W58 will be scrap long before the engine produces enough torque to wreck the A01B differential.

 

Anyway, isn't the A02B the same as the A01B, just a different ratio? The big diff is the B03B.

It's a differential, not a diffuser

Pretty sure the diffs go by the letter as to what size it is, so an A01A is the same size as an A01B. B**A/B is bigger than the previous.

A01B (N/A 4.083 Torsen) and A02B (T.T. auto 3.769 Torsen) are both small case diffs and the same strength, yet the A02B has a larger diameter prop flange.

 

Fit a diff flange from an N/A to the T.T. diff and you're sorted.

If you have an (A) size diff, regardless of its ratio number 01,02,03,04 ect and regardless of wether its an open or LSD A=open B=LSD

If the letter at the beginning is an A it's a small case

So your A01B and A02B are both the same size diffs

The B01B ect would be a big diff and require different flange ect

Really Sure one's my mind was on a spec diffuser

Thanks lot of advice!

 

Yeah i checked other forums and enlightened If i would use my car on the track, stick with the A01B, if lower rpm cruising on the street then get the A02B. To me will be perfect if i stay at the TT diff.

But It's not so clear yet that possible to match simply the W58 driveshaft with the TT diff, or need a little conversion?

 

Here is a full guide to transmission conversion. Check this site:

and found a other that's only in pics:

And really what about the auto ECU?

[Chris Wilson]

The pinion bearing preload is set by the flange securing nut torque. Just "swapping flanges" is not as straightforward as David makes it sound.

Ok! understand. thx.

it would be also my question yet to need to the propeller shaft(W58) any conversion to match the TT auto Diff(A02B) and gearbox(W58)?
