As far as the turbo argument I have to agree with DH, you can do whatever you want on a Z1 motor and it doesn't remotely relate. Your never going to run 54 psi on a 3800 although if you do try video it so I can see. In the little research ive done about turbo **** for these 3800's its obvious, you need a much bigger turbo that can flow decent air at a lower pressure. Not like a 4g63 or z1 where you can just keep turning the boost controller up.
