I ran a 16 flat with a 94 xe with a 35 wet shot. Had done a head polish and port match on the head myself, JWT ecu, port matched sr20 tb to intake manifold header, intake and exhaust. I was really pissed because I wanted to break into the fifteens and had I had one more run at the track I could of done it as I was dropping about .1 secs a run. Unfourtanetly about a week later the little GA succombed to blow by... still drove it for another 4000 miles before I bought my 200sx. It was fun with the 35 shot I still want to get another ga and turbo it for personal satisfaction. I'm not sure the N2O was responsible for the piston rings going as it was the first motor I ever rebuilt(for absoulutley no reason, the thing was spotless when i took it apart, AMSOIL FTW). And had ran without oil for ohhh a good 2 years(it was the first motor i ever rebuilt... you really should take the motor out and never get your oil changed at a shell lube, they like to forget to tighten the oil filter)
