I do need a new belt really as as far as I know its never been changed, but if yours is nearly new I may be interested.
I've put off buying one from the states as I thought I might get a smaller pulley and then change it anyway.
I was thinking of the 3.12 as I think I would be a little nervous about reliability on the 2.87.
Let me know what you do, as if I don't have your belt I may order a new one and we can save on postage.
I have used http://superchargeronline.com/index.asp before for getting a new oil jet. They are very good and helpful on the phone/email.
It might be worth checking your Oil jet/nozzle to see if its brass, if it is it's worth while getting one of the new stainless ones while your ordering stuff. The brass ones are known to crack (as mine did) and it took 4 weeks to get a new one!
