My 4x4 cossie turbo has arrived and my adapter to fit my S2 should be here in 2 days or so, so i would like to know what max boost i can put thru it? Turbo is mint no play done 60k, engine also done 60k.

I am curious as how much boost my engine can handle it is a case of getting it set up (fueling etc) so it can handle whatever boost the turbo can handle till it blows?
