While I agree that GT30's are certainly capable of making great power, I think that for minimal lag you can't beat the performance of VTG. With just our 65mm Billet VTG's we were able to produce 690 Wheel HP on a 997 GT2, and currently have a build going on in-house with our 68mm Billet VTG's on a 997TT. Remember, the whole purpose of VTG is to minimize lag, so by eliminating it, you have to compromise somewhere, either low end or top end power. Using the standard 20-20% drivetrain loss formula, you could say our 65mm Billets produced over 800 CHP. Are you looking for more? Beyond that, you'll definitely want to consider some engine work, so that power level is what most would consider "safe" without upgraded internals.

With our IC's, there's no cutting required. They are designed to fit right into the factory location. We previously used Bell cores, which seem to the be industry standard, but with our new proprietary cores, we've found there is absolutely no need to go bigger. Efficiency is key..

 

Not sure if u get my PM

Aftermarket intake system is a must with GT30/A30 kit since stock intake is restrictive

Proto/TPC coolers use stock hoses which is very good
