Re: 1989 Mazda MX-6 GT Turbo - Can it handle 12psi on stock internals?
 

My friend had a '90 Probe GT turbo, same thing basically, he had a 2.5" turboback no cat, zombie ecu, a cone filter, a Spec stage 3 clutch and a boost controller and he was running 16 psi running consistent low 14's (14.3@100 best) on street tires. He was running toluene in it and was ------- around with the timing like a dumbass and pretty much cracked a piston in half..but those motors are torque monsters..with that tiny ass turbo you could roll into second gear and smoke the tires.

Stock fuel cut is either 12 or 15 psi, I forget. There are a couple rednecks locally who put RFLs on stock ones, crank the boost, and drive around every day like real asshats.

It cuts out at roughly 12 psi, depending on actual airflow. Blow-off valves on Probes are a bad idea due to unmetered air ------- up the air/fuel mixture. :8
