Dont get me wrong,i love the feel of my cvh coming on boost even though im running a mere 18psi for 213bhp but im hearing of more and more cvh heads ripping rocker studs out every day...i knhow the engines are getting on a bit now and you've got to expect it.but when i build this next engine,i want good power,but i want it to last and be reliable.I just dont know what to do.im just scared that i will invest my money in a zetec,and not feel that turbo punch in at 3500rpm.i know the zetec is smooth throughout,but i want it to scare the hell out of me.
