Good to know.
So what about the M8270? TD06-20g 10cm? or 25g?
BTW if the M7960 really is a TD06-20g, then that's great. You honestly can't go wrong with either GT2871r or M7960, but the M7960 has one huge advantage. It's rebuild-able, so it will last virtually forever, where as with the GT2871r you would have to buy a new turbo basically. Either way though, they are both great choices. I think I would go with the M7960 personally. If you look at the old Tomei Arms turbos they were made by Garrett and were identical to the GT2871r. They had the .64 a/r and the .86 a/r. They were called the B7652 and B8446. Now they have these ones, which are supposedly "better" according to Tomei's R&D, so I can't argue with that.
