The guy just sent me this in a E-mail
>>>>>Tom,
          It is a T3 with a 45 trim compressor with a .42 A/R, a 69 trim turbine witha .48 A/R compressor. It has an internal wastegate with the standard T3 4 bolt in, 3 bolt out. It comes complete with flanges and gaskets which most people don't sell with theirs.
          This is a turbo I actually ordered for a 2.8lt engine I was working on. This project was put on the back burner pending the completion of a another much more powerful project! It's on the smallish side but will deliver the power you are looking for efficently and still spool rapidly. I've also tried to price it well and including the flanges and gaskets, I believe it is an excellent buy.<<<<<
He also sent me a link to turbonetics compressor map for it
