Anyone ever done this ? Only qualm I have with the imports is the short ratio box which is fine on long jouneys power wise (obviously I guess) - but just feels painful.

Could you just stick a UK box in there or is the final drive ratio different as well ?

Cheeers

As long as you change the box and diff for a matching pair, all will be fine.
Jap boxes have different diff ratios, and a different transfer box.

 

OK cheers Steve. Is that the limited slip diff at the back you're talking about ? Probably not...!

 

All turbos have a LSD at the rear anyway, but this has nothing to do with the diff ratio.

 

No didn't think so !

OK so basically I need both parts the gearbox and the main diff then.

Anyone ever done this by the way ? I haven't heard of people doing this which is surprising really cos the ratios are a wee bit too close for cruises I reckon.

 

Plenty have done it...You need the gear box, and rear diff...
Not sure what you mean by the main diff

The gearbox houses the Centre diff/Transfer box, and front diff, whilst the rear dif is a seperate item.
