HAHAHAHAHAHA.. From TRD.. Toyota Racing Development.. A California firm, maned by experienced American NASCAR techs, specialists, engineers, and engine builders.. Employed by Toyota to supply engines, and other racing equipment to NASCAR teams.. So unless your name is MWR, or JGR I don't think you'll be on the list of approved customers..
You see when Toyota was invited into the NASCAR family, they couldn't meet the requirement of using a factory supplied cast iron block.. No foundry in Japan was equipped to make one.. So NASCAR said to forget it, and don't worry about the casting.. Also here are the specs for our next generation engine.. We'll give you a head start on that, so you won't have to develop two engines.. Good luck getting the engine.. My guess is passing emission tests will cost you as much as the engine, if you get it..
Edit: Nope, it takes more than a NASCAR license.. Hendrick Motor Sports ain't gettin' their hands on one of these babies..
