I've come all the way over here to ask a question that my learned friends in Aus dont seem to be able to agree on. I have searched your forum to no avail, so I thought I'd be rude and ask a question on my first visit.
I have an Astra G SRi Turbo, It's the Z20LET 200hp version, I have a 2 1/2" cat-back system only and I am sourcing an EBC (GReddy profec spec II) at the moment. I am also getting an electronically adjustable Fuel cut defender to limit the spiking and to avoid limp mode.
Seeing as though there are only 300 Astra Turbo's in Australia, my resources are limited, even tuning shops have no idea.
My question is; how much boost can I safely run on the standard engine, and what spike limit should I set?
Also, does anyone know what the factory boost settings are for these engines?
Your advice and experiences would be greatley appriciated.
Thankyou in advance,
