James,

If you already have the 38's, then by all means run them. I don't think anyone argues that external isn't the better option because you can properly size them and achieve greater flows and you have to assume a $400 WG is better than an internal in a $800 turbo. To make a blanket statement that internal won't vent off at high boosts is probably over simplifying and I would suggest its going to depend on the independent turbo design. Size is the issue and port flow in an internal WG with possibility of more turbulence in the exh housing.

And as you suggest, few of us are running "high" boost. Have you mapped out the piping, because ext. WG certainly makes things a lot tighter back there unless you plan to vent to atmosphere and HEAH why not

Your going to run an electronic boost controller anyway to improve boost control and help hold that gate shut without leakage in any case, correct?
