The N21R went to a local Austin racer. He was excited to get it. He has only ran GO Engines, and didnt have a 086 pipe. He also won a $50 Gift Certificate for the local Austin Hobby Town. So, he was going to go get a Ofna 086 Pipeset. Told him the plug to use, and to take you rtime breaking it in. People were amazed at my little Stock N21R, Ran flawless all day.
