When I selected the cam I chose to run, I contacted Ron at ISKY cams and explained the engine setup (turbocharged stock longblock with bolt-ons), the turbo I was using (T-66 p-trim with a .58 a/r turbing housing), the RPM band I was looking for (where I had full boost of 20 psi at roughly 4400 rpm's), where I was intending to rev the motor to (7000 ish rpm's), and that I wanted the power band of the cam to match the power band of the turbo (4400+ rpm's). I knew I wanted 114* lobe centers and a staggered intake/exhaust duration with a longer duration on the intake than the exhaust, to speed up the exhaust flow out of the engine to help aid in turbo spool (atleast that was my theory behind staggering the intake and exhaust lift/duration). I am certainly not advocating the cam I chose to everyone, as a turbo motor's power band is somewhat dictated by turbo size and exhaust a/r. I don't think that a stock size turbo would have benefitted from my cam choice, but the large frame turbo certainly did.
just my .02
