I am very interested to see this aswell, I currently have an s14 sr head being ported as we speak and the typical gains from the engine builders experiance are 10 to 15 percent better flow increase, and all around more efficiancy… I can not see this generating 100 more crank hp… The amount of boost would have to increase at least 2 or 3 psi to generate that kind of power from a stock motor with headwork and now other modifications… I have never seen such gains but if this is possible, post up some pictures and dyno results of your work, I’m sure many guys on here would be interested!
