I actually went with the GT3076R. It's definitely more laggy than the T518z but pulls a little harder up top with the same amount of boost. Tune is not finalized yet as my fuel pump isn't here so I'm still running at 1 bar (wastegate/actuator pressure) same as before. Will be tunning for +20 psi later.
Clearance is VERY tight with the Greddy kit. I ordered a low profile fan kit for a cleaner look later but for now it works perfectly.
The videos aren't a very good comparison as it spun considerably more with the GT3076R and I had to let off. But from 120-160 you can tell the GT30 is pulling slightly quicker at the same boost.
