welcome! Good story, more and more people are buying the 3sge to use as a track motor. Are you going to be staying the n/a way or turbo? n/a will be clutch, flywheel, headers and the rest of the exhaust... maybe some more aggressive cams and ecu. There's a guy on here that is using his n/a on the track, you can find his build here
not much about the figures he's putting out though but it's looking promising! But one thing.. tuning these engines is $$$$$ haha.. suspension will be the usual, coilovers, braces etc... good luck and keep us posted!!
