thalj, hello in Dubai.
I recently started a thread asking for comments concerning supercharging or twin turbocharging for the 1UZ that I have installed in a new Toyota truck. For my driving and personal preference I decided to go with Twin Turbos. I have a stock engine, '97 Celsior, and it will be a daily driver. For me, the best is low boost, twin turbos, intercooler, Autronics ECU, oil cooler, manual transmission (R151) and dual exhaust. My goal was the best throttle response possible, reliability and some good torque. I spent a lot of time sorting out what I wanted as well as what I needed. My humble advice to you would be decide how you will be driving your vehicle and what you want it to do.
P.S. I lived in Jebel Ali for some years.
Good luck and hope to see your completed project here.
