It will hurt you on a NA car. They dont keep the valves open long enough for the air to be pulled in.

FI cams have it setup with very little overlap, so that you don't leak boost right out of the exhaust.
the VT "stage 2 FI" cams have a 220/230 duration while the "
stage 2 n/a" cams have a 225/235... not much difference there. The duration on the FI cam is 112LSA though compared to a 108 LSA on the n/a cams.
FI cams generally also have a lower intakelift, at least the VT ones do compared to each other. but its really the combo of the LSA and intake lift that would kill you on a n/a car, not the duration.
In any case, its a bad idea. in this case, nitrous will simply not act the same way FI would.

RE: what is a good cam to run
when they say f/i they mean boost normally...
although they do make nitrous cams as well i believe... atleast for imports, so they should make em or make some custom grinds for you for a nitrous setup car.

its not nessicarrly the duration that hurts a N/A car running a FI cam... its the overlap of the intake/exhaust valve that is either severly cut (time) or hardly present at all.
