I'm close to purchasing this:

T3/T04E Turbocharger w/ wet floating ball bearings
hot side: .63 A/R, Stage 3 turbine wheel
cold side: .50 A/R, .57T compressor wheel, 3"in/2"out

I'd be setting the boost controller to 15-18 psi and using a spearco race core IC. I'm using 2.25" IC pipes and 2.5" to 3.0" open exhaust. I have a 5-speed w/ 7200 rev limit.

Anyone running this or anything similar? What are your boost conditions? How does the turbo "act"... and does it make good power? How does it feel on the streets?

why the 57 trim compressor? its not the most effecient of the larger t4 compressors?

You can have it cheap, fast or good. Pick any two.

If you want it cheap and fast, it's not going to be good.
