And that you have a turbo guard instead of the K&N air filter to be able to make the 16.4 psi, since I'm not sure if everyone is running with a turbo guard or not.

The spacers you can get from 928 for less than $30.00. Those have nothing to do with boost levels as he was asking about.

My car made over 10 psi with the Si sc, 9lb pulley and stock filter. That's why I believe he will make over that with the 928 upgrade.

But yes, when I went to the 3.47/3.00 combo I went to the turbo guard.

My car also made 12.86 psi with the stock Si sc, 9lb pulley, stock 3.2 jackshaft pulley, upgraded 2.85 sc pulley and stock filter.
