I wouldn't trust that guy, he doesn't even know much about his car! First of all the B18C1 is the motor from the Integra GSR, and it has 170HP, not 180HP. And there is no "special" JDM B18C1, actually in Japan its called the B18C without the 1, the 1 is only for USDM markets. So dunno what the heck is talking about there. Obviously he built it just for show...but a 4dr civic with a B18C1 ain't that fast at all and juicing it with a 75hp NOS without any bottom-end work is dangerous. I wouldn't buy this thing if I was you!
