I hate to say it, but our 3.5 V6 with it's body weight utilizing a turbo isnt worth the money. The boost lag involved with the turbo spooling up is going to be extended before you actually feel any power unless you decide to do some MAJOR modding. To get it to work right with the VX, you are looking at trully customising the vehicle. Lighter panels and whatever else you can throw out, complete header/turboback exhaust system (catless), complete street tune (our computer is not very friendly with custom tunes since it thinks on its own rather well), complete cooling and induction system, and fuel system upgrade. Thus, why the wealthier than God JDM owner was able to complete such a task and he eventually put it up for sale. Doesnt say much about his creation, heh.
The S/C is a much better choice for the instant power at your command at a reasonable price.
The only reason you see turbos on large trucks is because they are pushing diesel and/or a V8 or larger, and then they are still only powerful, not necessarily quick. Ah, the scary sound of a V10 turbo diesel though.
