i have a 1995 acura integra gsr and i have a couple of bolt-ons but they really didnt give m the power i tought it would give me.should i get it dynoed and tuned or what? and also my snd gear is going out and i wanted to know if i sould just swap it for a jdm b18c motor? and is their a big difference in between the b18c1 and the b18c in hp/torque?
