No matter what you do make sure you replace items with new gaskets.
Also any engine with an 3l or 2.5liter with a respectable turbo will give u mass tq gains. Look at the adc turbo kit. Gives alot more low end tq then the voretec supercharger. The story of turbos only building power up top isn't always true. And yes the vortec is linear so boost is created later but the turbo spools sooner for our application therfore boost is sooner which equals more power at low rpms.
There for 6-8 psi will still cause you traction issues. with a 2.5 of 3l liter.
