Casey Penn spent all of 2009 perfecting his SR20DET powered Nissan 240SX (S13).  Like most of us drawn to the exiliration of racing, you can never have enough power, so Casey decided to swap engines. Casey managed to fit the Nissan VQ35HR engine under the bay of his 1991 240SX, while gaining only 30lbs of weight!  I asked Casey if he could loose any weight, but he said that carbon fiber body panels just weren't in the budget at the time.  I guess he didn't get the joke.  Casey's car is quite obviously a THMotorsports favorite, being a race car and not a "dog and pony" show car.
