Looking to upgrade my ST80 T4

Well the sickness is getting worse & worse I'm thinking about getting a slightly bigger ci and upgrading the turbo.

Maybe ERL 6bolt 370-400ci
Main problem is the turbo size I don't have much room in the engine bay.
I thought about the T4 91mm (Like Mighty Mouse's turbo)

Aneone have a any pics for similer turbo sizes next to each other I wanna see how much 91mm physically larger over ST80 ?

I know the turbo still have a lot more left in it (ST80 1.15ar 83turbo race cover) I'm still on 11.5psi 670rwhp but I'm sure turbo will be maxed out 900rwhp right ??

I'm looking for 800-900rwhp mid boost & 1100-1200rwhp on kill mode with the new setup.

Here is some pics

as you can see turbo is very close to the tensioner and clear the hood by 3-4fingers

Thanks in advance guys & waiting for some info.

I vote 390ci with some smaller twins if your keeping it a six speed.

I'm keeping the six speed for now

I thought about going twin but I don't want to replace the whole setup Corvettes Twin turbo kits are expensive.
