V6 with custom injection and adjustable boost control. I heard it is very 
poweful (well over 300hp)and properly done with custom intake manifold, 
intercoolers and low compression pistons. I don't know the costs envolved 
or wheather it can be used for street or why even bother building it for 
street use, but it exists and it ran a rally in Michigan this winter.
