think of a *relatively* small trim (46?) T04E with a .50 a/r compressor - emphasis on the relatively, T04E's are still BIG. This happens to be an extremely efficient compressor combination even at very low boost. The exhaust side has a T25 flange and that is the only thing that is T25 about it. Garrett ballistic 9-blade exhaust wheel which has a good response and is also very high flowing. BB is nice too.
Bryan, great to hear that you are up and running. Does the feeling you get when driving it outweigh all the time and money you spent? I hope so, for both of our sakes LOL! I am happy for you. We still might see a 10sec Z this year WOOHOOO!!!!
