Hey Sean K,
Yes, you could install a after market supercharger for your Aurion, because TRD has creased production for this car. I have mine installed with a Rotrex supercharger with a transfer rod from TRD.
1) Rotrex supercharger for 3.5L and above kit
2) Transfer rod from TRD and enhance / reinforced for rigidity in mounting
3) Water cooled intercooler for compressed air before in-take into the throttler
4) Oil intercooler for gear box
5) K&N filter
6) Sub-ECU for control over gasoline & air-take
I have yet to have mine on the Dyno machine to see the HP figures!
Stay tune, as my mechanic's Dyno machine system is down, having to re-install the software!
