Although, I dont think there is much HP to be gained in the intake manifold on a stock motor.

PBJ ported out my intake runners to match the ported heads. Joe has been talking about opening a stock intake up to do a full port job, thru and thru. If that interests you, you might talk to him about it.:dontknow:
I'm not really looking for HP gains. I'm still trying to make the STS system work. Some have said that the airflow on the GEN 3's is not the best. That is why the #3 seems to be the first one to go when someone loses an engine. I was thinking of something to make the air flow better for the turbo.

I spoke to Rick many years ago about my TA and back then he said headers wouldn't help the situation much. . . . Wouldn't hurt it also.
May be different for our trucks though.
FAQ off their site.
Do I need to put headers on to optimize the turbo system?
No, the extra expense and work to install aftermarket headers isn't necessary. Headers are designed to eliminate backpressure in the exhaust system and facilitate exhaust scavenging and flow on normally aspirated engines. Turbocharged engines work on slightly different principles. Namely, there is exhaust "Pressure" between the cylinder heads and the turbocharger because the turbocharger is the smallest diameter orifice in the exhaust system. The turbine housing gets smaller in diameter to increase the velocity of the exhaust gasses before they hit the turbine wheel. This is how you get 100,000 rpm wheel speeds.
Turbocharged exhaust gas pressures can see as high as 30+ psi on high boost applications. So spending money on higher flowing exhaust components designed to lower exhaust backpressure is usually a waste of money. This money would be better spent on an upgraded turbocharger which would produce more efficient boost with less backpressure or just spending the money on upgrading the engine and fuel system to handle more boost.

Maybe I'm not being clear. I'm not talking about headers. I'm talking about the intake manifold that is on the very top of the engine.
