If your after one then speak to
http://www.aet-turbos.co.uk/ they do a decent deal - they also do the one you want - .82 rear end - their seems to be many different variety of these turbo's so i've read on various Jap and Ford sites and it seems, again from what i read the 6 blade version is better for pickup over the 7 blade but speak to them - mine was on a M.A.D car and was purchased through AET. Mines a 3076r with internal gate
