anyone use or know about these turbos? they any good to use for the 3rd gens? im shooting for around 420hp at the wheels reliably using one.. and im not sure if i wanna use one or not.. ive been lookin at the gt-k 550 and the gt-k 800, both have good a/r ratios but i dunno if they will support my goals or not and be able to do it using pump gas!

We have been using the GTK-550 on the Falken RX-8 this year, and it makes 500rwhp and 425tq at 21psi with zero split and only 8 degrees total timing. Really smooth power curve. I highly recommend that turbo. BTW, that is on a 13B-RE engine.

im looking to purchase this turbo and run it around 15-17psi on pump 93 octane and hopefully break around 400rwhp at that boost level and have quick spoolup.. im debating between that turbo and the usual gt35r.. cause im only lookin for 400rwhp and quick as heck spool! below 3500rpm..
