300-350 whp garrett t04e 57 trim????
I need to order a turbo tonight, I have a t4 flange on my manifold. 13bt with a street port, my goal is 300 hp at 10 psi or so and 350 or higher at 15 psi or so - hp to the wheel. I was told a t04 60-1 is a bit overkill for my goals and from what I have found in the past few days searching and learning this is what i came up with-let me know what you know- tell if im off here. I need to order a turbo tonight to get my car out again- THANKS!

A Guide To Garrett’s "GT" Model Numbers
GTxxyyzz:
Positions "xx" refers to the frame size of the turbine wheel inducer.
-For example the "GT28" in "GT2860RS" refers to its turbine wheel frame size family. All GT28 units use a turbine wheel with 53.85mm inducer diameter
-As a rule of thumb, the larger the number, the larger the turbine wheel.
Positions "yy" designate the compressor wheel exducer (major) diameter in millimeters
-The "60" in the GT2860RS example above has a 60mm compressor wheel exducer diameter.
-Note: Wheel sizes 100mm and over omit the "1" (hundreds digit)
-Example: the 02 in a GT4202 refers to its 102mm compressor wheel exducer diameter
Positions "zz" may be used to designate special features of a particular turbocharger where applicable
-Example: GT2860RS
-"R" = this is a Ball Bearing unit
-"S" = used for units which require some differentiation from units in the same family
Compare a GT2860R to a GT2860RS. While both are ball bearing and externally similar, the GT2860RS is better suited for higher-flow applications than the GT2860R. In this case, the S reflects the higher-flowing nature of the GT2860RS

That's the short answer.
The long answer is that there is just too many variables to consider when talking about boost characteristics, and unless you can replicate someone else's exact set-up, it's next to impossible to give you answer.

You've probably already seen these, but just in case...
