Reason is that 95% of the questions asked have already been covered or someone doesn't know the answer lol. There are a few regualrs and MOD's that frequent the tech forums though.

Most of what you need to know is located right here:

Jeff Evans is a tuner in PA, i've heard NOTHING but great things about him. I was going to him last yr for my supercharged gsr but unfortunately had to sell it before I could make the appointment. He tunes ALOT of cars but primarily deals with hondas/acuras. If you want to know how to PROPERLY build your b18c1, do exactly what he says.
