I am looking at purchasing a larger turbo for my 87 TII. I have gone through the calculations (with a T3-50), but I do not know what the numbers mean?

From some reading (and correct me if I am wrong please), the T3 is a flange style, and the 50 the trim? I am not sure how to do so. I am looking to be in the 300 to 350 hp range, and going through the calcs, the T3-50 seems to work so that I am not surging the turbo. It shows that I will have full boost of 12psi at 3500rpm and hold until 7000rpm. Any thoughts on this? Thanks.

Here is the image for you to look at for the turbo.

Would a T04B with a 49 trim, 1.32 A/R exhaust, and .6 A/R compressor work? What I am looking for is a fast spooling turbo (fully around 3500 to 4000) of 12 psi, and around 300-350 hp. Thanks again.
