The guy selling those is a misleading crook. The people that leave the postive feedbacks don't know they were had till it's too late. They are the same "T70" (61mm) turbos that SS autochrome sells. He angles them so you cannot see the square tag area on the compressor housing. You can get the same turbo for a 1/4 of what his sells for. The is another guy or maybe even the same POS that shows a pic of a polished one, but in small print says polished is extra. He has GT35 in his title too, or did. Those turbos DO NOT have ball bearing center sections. I bought a kit and sold off everything but the WG. Ended up getting a basically free WG out of it.
