I was curious where I could buy one, or buy the kit. I remember there was a company out in australia that built them. Anyone remember the webpage name?

from this page:

"Engine building starts with the intended application, owner expectaions, and budget. Pineapple Racing is capable of building almost anything you can dream up, from a tame, non-turbo street engine to a high-boost, nitrous injected drag racing motor to a 4-rotor monster (yes, one is in stock and ready to build to your specs). For racing applications, Rob can build engines to the limits of the rules for all of the popular classes. For street use, Rob helps clients get the most bang for their buck by offering proven packages of upgrades to suit almost any application and budget. "
