There are lots of breakers out there specialising in BMW.. just have a look in BMW Car or similar mags.

I would buy one of those rather than a recon one.. it may not need doing.. but if it does you could take it to a transmission specialist of your choice and have it set up as stiff as you want.

Hi there, regarding the bumper swap etc. I was told by a specialist that it's not really possible to do anything with the rear end in terms of changing over - he said it'd be easier to cut the back off and use that of another car! Although you can apparently fit all the parts to the front end.
If you're after more torque a "rally cam" is not the way to go, they're usually designed to work properly from say 4000-8000rpm on 4 cyl engines.

Hmmm... would you be better off with a 318iS for autotesting? You can pick up a good 318iS for £1200 and it looks as if you are going to spend a third of that on a diff... the last LSD I saw advertised was £425 (standard diffs are much cheaper).
I love my 325i Sport but a 318iS has to be better balanced. Enjoy, anyway ---

Better balance but the engine will be rubbish for what you plan to do, the torque and power is all up the top end so you'll need to rev the hell out of it to get it to break traction.

Paul, point taken. BTW, I used to have an Alpina C2 2.5 with the 4.1 diff factory-fitted (well, Alpina-fitted) and the result, with a factory dogleg box, was 0-60 in 6.7 and a top speed limited by the gearing to 141mph. All from 190bhp.

The gearing did not feel too low at the time, but today it would, because we are used to higher gearing in more recent cars. The only problem was that the dogleg box had a conspicuous gap between 2nd and 3rd and the engine fell out of the power band unless you were somewhere near the red line in 2nd.

PS - It occurs to me to ask: B858JRD, are you out there?

For track use the 4.1 would be fine, but like you say i was thinking of it in a practical road application where it would have made the car a pain to drive on motorways etc. 

Good luck with the search.
