I would like to acheive the 400+ level of hp with the combination of components that I am going to compile. I need to do head work with the amount of fuel that I am going to be flowing through, unless anyone knows other wise, but I would like some feedback from anyone who has head work done to their sr20det, I want to know whether it is beneficial or not on the sr motor

who is enthalpy and how do I get ahold of him?

thanks guys
