Blew the head gasket. Buy Nissan only. It's time for the next level. Engine and transmission are getting a nice over haul with some new seals and gaskets, T3, light weight flywheel, aluminum drive-shaft and 6 puck clutch. Also added some new poly parts thanks to Z31parts.com. I have the second version of my mini itx CarPC in the works, and will be starting on a direct port nitrous setup soon. The best part will be the addition of NISTUNE programmable ECU thanks to Mark at NISTUNE, courtesy of Gregmatic.
