There is one that comes out frequently. His name is Red Top on here and he's got a SR20DET swap and Silvia front end conversion, as well as other things. He is doing really well, but he is defeinetly not in stock class.
The cars do autox well and I don't know why we dont see more of them out and the torque defeinetly helps out autoxing. I've got a little bit myself.
Keep in mind you still can upgrade struts, air filter, exhaust, harnesses, and tires in the stock class. If you do come out there are plenty of Nissan guys out there like me! Hope to see you out there.
