Sorry guys I've been busy at the shop. Another option would be a Rotrex supercharger set up. It is easy to install and very compact. We have successfully fabricated a kit for a Lexus GS400 and can be easily adapted into the VX. I anticipate the kit for the VX to be around $5800.
Here are some pics to get an idea how the setup looks like:
