MkIII T04 Turbo Installation

This summer I'm going to do alot of work on my 1988 Supra Turbo. Is it hard to put a T04 Turbo in? I know it needs a adaptator and a wastegate. What a kit for the T04 should I buy? I did all the work to it so far but I'm wondering if I should just get the CT-26 upgrade. How much pounds of Turbo can a T04 give and the CT-26 upgrade give of?

Thanks, Here are my mods

K&N FI Pk
HKS blowoff valve
Magna spark plug wires
550cc Injectors
15 pounds on turbo on a Ct-26
Spearco intercooler
Turbo elbow
Hks exhaust & test pipe and Down pipe
No cats
fuel pump and manual pressure regulator
Lexus/REMI air fuel management system
Clutch Master stage 3
Fluidine radiator
Greddy boost controler
Gauges to monitor everything

right now i got the 60-1 trim ct-26 upgrade, i'm running 23psi.
Yeah if you want the ct-26 upgrade would be a step up.
What do you mean by T04 upgrade, To4e or To4b?
It shouldn't be that hard, oil line from earl's performance, a turbonetic wastegate, and a suprasport.com flange..
The T04E would support to 450hp.
