TRD Compressor .

Hi Meverik1.
I think the supercharged 2GR FE was only available in the TRD Aurion in Australia.
I think Toyota Australia were reluctant to sell the parts to anyone except genuine owners of TRD Aurion cars.
Those parts may not be available any longer after such a long period of time.
You may be able to authorize someone in Australia to purchase a second hand TRD Aurion for you and have those parts removed and shipped to you. 
I think the parts you require would be the complete inlet manifold, pulley system, injectors and supercharger.
Someone more knowledgeable may be able to give you a better understanding of what is required.
This engine in the MR2 is absolutely brilliant. 
I hope this is of some help to you.
