Yeah I have more questions about the whole turbo deal.

First I was just wondering how you get more 'boost' or psi out of a turbo. I've seen setups for a B16A that ran a ridiculous 24psi out of a GT66, and if it's possible to even get 18psi for me, would be perfect. I already have the plans to replace my cams, cam gears, pistons and connecting rods. Everything else on the b-series stood up to 500+ with just those replaced and that turbo setup(the other stuff needed i dont remember them all), but i also plan to replace the valvesprings, retainers, and heatshieldng the turbo from the areas around it.

I just don't understand how to change the boost on a turbo or how i would know what to change! (dont worry as i will do alot of work and testing before i try any of this)
