The turbo was kind of a payment/gift/barter from a co worker of mine who needed some parts fabricated for his brothers SRT-4 (very very very fast little car) so beings how it was free I can totally feel free to spend money on modifying it to work. I tried to give him $100 for it but he would not take it, instead gave me the wastegate too. So if I tell him I need a different one he might go buy it for me (kidding). I do not know any other specs on this turbo aside from p/n 456159 on compressor which is a t4 .60 ar on compressor, .63 ar on exhaust and was told it is a 50 trim.
