So this is the Turbo that I'll be getting with my engine buiild up, I tried looking over some of the turbo posts but I still don't get it, could someone give me a rundown on how good/bad this turbo will be: TO4E 57Trim with 360 Thrust bearing upgrade.



Thanks.

So no one's really got any help for me or able to point me in the right direction?

Yes that will work great on the street. Just make sure it has a t4 turbine footprint, and a P trim turbine wheel. Don't go too small on the turbine a/r either. No smaller than .84.



Thats a to4E 57trim on my workbench...

I do not like hotsides smaller then .96 but hey there hard to find in smaller turbos. It would be a nice turbo on the street but still fall off a little up at red line.

It depends on what your looking for and how you port your motor. Port timing and turbo sizes greatly affect the powerband and peak power. If your running stock ports, you should be good with that turbo. If you plan on even a milder streetport, I'd run it up a lil..maybe a .96 or more on the hotside.... def go w/ the T4 though as E said....
