Can someone please confirm if the R180 diff is available as a 4.1? If so what was it fitted to and does anyone know who might have one to sell. Thanks.

 

Someone must know?

 

As far as I am aware the 180 came in the Type R coupes from 1998 My on and is only available as a standard fit as a 4.4:1 Maybe there is a different ratio available from STi [ the company not the car] I don't know.

As for the diff in a New age car I have no opinion at all.

Thanks for that, had heard exactly the same myself but reading through another thread on the electric centre diff someone made mention of a 4.1 as an R180, hence the question.

Edit:

Just found the post, by Adam M:

"my car was and is a jap.

the final drive is now 3.9 which is common to neither 22B since the jap was 4.44 and the UK was 4.11.

The UK 22B still has an R180 but crown wheel and pinions for R180s in anything other than 4.11 are an absolute pig to find, and if I strip thse, the likelihood is I will have to revert to 4.44 which might be a touch manic!

The centre diff does just bolt on, but even if you can get hold of one (rare but possible) you need the diff controller, and these arent quite so common.

If you need help with such things, then the best people to speak to on this are moray mackenzie and pat. "
