im currently running a t3/t4 57 trim turbo right now in my teg. but im probably going to build a hatch. how our the T3 super 60 with a .48 a/r compressor and a .63 a/r turbine?
Any turbo can be a "good turbo"...its a matter of having the correct supporting modifications to promote the turbo and the tuning time and quality that make it happen.
How much power are you looking to make?
Where do you want your powerband to be?
What are you going to use to tune?
Is this car for street or track use?
How is the compression of the motor in the hatch?
What motor are you building in the hatch?
Just a few questions you need to answer before asking if things are "good"
