No this one with the nice engine is in an E Production racecar. IT engines are little more than cleaned up, optimized street engines, less power less money and more relaible. After many years of racing IT, I stupidly decided to sell a perfectly good racecar and build a money pit racecar. If I get smart, I may go back to IT as I have most of the parts needed to build another car.
