i got 517hp on my 3076 .63 a/r at 23psi. stock fuel rail,regulator lines and a walbro 255 pump, tuned on an old hondata stage 2bd. block is sleeved(83mm) with pistons and rods the head(factory type r),cams,intake are stock.
having a/c in they car makes everything really really tight and isnt worth the hassle . sammy(itr41) wanted to just say he had it but it was melting all his lines.
