you might check out Magnum turbos they have a polished compressor housing, and almost the same specs as master power , i bought a master power t76 here recently

 

Thats probably wat I will go with if or when this one goes out on me. I hope to make my first pass at the track this friday with the mp76. Need to find out how easy it will spool on a 4.8

 

im pretty sure magnum is running a special this month a 76 ptrim ball bearing for the same price as the journal bearing 76ptrim

 

Yeah my brother bought one last week for $800 shipped!

 

Stay away from On3performance. There is a good reason why their stuff is so cheap. Its Junk!

I ordered a T70 .68ar for a customers 400hp B18. Once the turbo came in it received a full inspection like normal, and we found casting flash throughout the exhaust housing. Not just a little piece floating around. I'm talking china special 3/16-1/4" chunks not even deburred. ( I send a baggy with flash and debris) I contacted them and they claimed that this was a fluke and they inspect every turbo but there was no way anyone looked at this turbo they sent. I returned the turbo (at my cost) and purchased a T70 magnum and he couldn't be happier.
