I drive now an NA turbo-ed engine, because I miss shifted my other engine, and over revved it to 8800RPM, what killed it ofcourse... So i have put al the GTD parts on an NA solid lifter engine I had laying around.1.25 Bar 20PSI k24 turbogovernor mod, aneriod,...fmicwithout oil scuirters.109Hp @ 5400RPMdrive it like ***ing hell... rev it to the max always and everywhere... :roll: still goes wel after 3months now.only had to change head gasket. But that was already leaking when it was an NA..also a couple of exhaust manifold gaskets and studs, because I never warm it up. I rev to 6000rpm with ice cold engine.Don't care. Engine didnt cost a thing, except the head gasket.
