What turbo would give me the most power at 6-8psi

[Toyotafanatic]

Im not sure about the ct-26 on the supra but I know on the ct-26 on the mr2 it can boost up to 17 psi, but you definetly dont want to take the stock turbo past that, now would that apply to the supra ct-26? and about which one supplies more power, voloume is the key, so the size of a turbo and the trim all has different effects on the power, so go I would suggest a good combination of a big turbo and a trim size so you dont have to spool that thing for an hour lol.
