High Ian From Oz.
I have a Westie SEi Aus version. (now called an Arrow)
It uses and english escort diff in the alloy carrier. (as I think the early cars did there)
I am looking to repower the car with a Busa.
The problem I have is the tallest diff ratio I can find for that centre is 3.56. (If you know of others let me know)
As you are no doubt aware I will need something in the region of 2.9- 3:1
I am currently getting quotes to make said gears.
Just wondering if there is any interest in this over there.
Not trying to make a buck but if I can reduce my costs by increasing the numbers then all good.
Cheers Ian
The tallest English diff is a 3.54 as you say. Iirc someone looked into having bespoke ones made over in the U.K. and they were about £1500 each. If
you have an SEI doesn't the "I" stand for independent so it should have a Sierra diff which has a 3.14 available (but rare and
expensive). Has you chassis been modified to take the solid axle and so can be put back to independent?
This guy does a 3.3:1. http://ntgear.k.b2test.co.uk/product/english-7-axle/
Old thread here. Looks like the same people but the web address has changed. http://www.locostbuilders.co.uk/viewthread.php?tid=1975

It is independent. But it uses the English centre in a cast alloy housing.
I thought this was how your early SEi's were done before the Sierra. I could be very wrong on this though.
We never got the Sierra here so if you think those diffs are rare there....
I could of course re engineer the rear to take a Freelander or BMW diff.
But. There is no guarantee of getting rego. Becs are near non existent on the roads here.
I need to be able to put if back to how it is now if I fail.
Noise will be the hard one. It will need to meet the same noise rules as a brand new car did in 2004 (when it was originally built)
Hope to have a rough idea of price back in the next few days so will update then.
BTW thanks for the link to NT Gear they may be worth a quote if a local here can't do it.
Interesting, found this link to the diff in question. Not heard of that before.
