The Mooncraft turbo kit is custom made by his racing team, if I am correct. Totally fabbed for HIS VX. I am sure that for the right price, he would be willing to mod you one, as well as his sweet cladding kit. Of course, if the cladding kit ran $5k, as it was stated, the turbo kit won't exactly be a penny from the ashtray either. 
I plan on going dual exhaust here as soon as I get off my butt and take my VX to my brother to do. No hp gain, and as I heard from others here, there may actually be an extremely slight loss in hp. Correct me if I am wrong, but I do believe that is what I heard.
