Hi
I have the GTK650 on mine
it´s a nice unit mines spool well at arround 3500 rev (15 psi) but it is super stronger over 4000 rev (30 psi)
and it is capable of more than 37 psi !!!
if the GTK500 is a little smaller than the GTK650 on the hot side , you will be happy with it .
but upgrade the engine to hold 20-25 psi

so jos what kinda figures are you putting down are you dynoed? would running a GTK 650 with supporting mod's between 15 and 18psi make sence on a street driven 7MGTE Supra

uhmm the GTK650 is too big to use at only 15 psi ... that turbo is happy when bossting over 20 psi.

No I havent dynoyed it , the last time an spark plug broke and i will not take that risk again... with an GT35R my car dynoyed 540 HP at 20 psi
now with big exhaust and boosting at 30 psi I am thinking maybe 700 hp ???

I am happy anyway. jeje
