i have a ls vtec with b16a1 head with pr-3 ecu.
vtec at 5300. gov at 120 mph.
is ur vtec wires run correct?
is ur vtec oil line 4an or bigger. im using a 6 line.
someone put a 2an line on my shit and vtec would never hit.
i also had a stock ls b-4 i went vtec. now it seems a little faster before vtec but not much more than before but after 5300
hehe. fuk dat ls bullshit valvetrain. i also have 11:1 comp ratio
so you should be fuckin flexing out hardcore with that setup. if ur doggin something is wrong. u got vtec oil pump to right? and all other shit to i hope.
