Hi again there, I'm sorry, if you are running the gear at 8-10 Psi, standard wastegate should be fine. Are you referring to T04E or T04B. They are both relatively the same - High Output 550Hp @25 Psi, Drag event MAX 30Psi. Identical T04B GARRETT turbocharger was used by 1993 Rx7 owner. He ran 11.27 and 121Mph at Eastern Creek (Unsure if i got the figure right). Regards,

Hi there, Standard wastegate should do fine if you are going for T04E hybrids turbochargers. If you are going for 650Hp Super T70 turbocharger - should get external units at least 40Mm wastegate (pictured). Regards,
