thats what people always say but a gnarly turbo cam has profiles like an all motor cam. if you run a nice blower with a good amount of boost you can make good use of a bigger cam. i beleive you want a cam with alot of duration and little overlap

Re: (quicksilver1689)
JDogg and I have actually tried this on the dyno with different cams and a supercharged motor.
Boost cams don't have a lot of duration, they just have a lot of lift, duration at .050 is similar to GSR intake and ITR exhaust, which is what you want for a boosted motor.
Dialing out overlap with high-duration NA cams causes other problems. Don't use them for boost, they suck at it. If you've got some S2S2 cams, then sell them to a N/A person and buy something better for boost.

Re: turbo cams? gsr and itr? (Pr0j3ctxH@tchx90)
Look at the specs:
<U>CAMS______________Lift (I/E)_________DURATION (I/E)</U>
GSR___________________.423/.378______________236/224
GSR-I/ITR-E :___________.423/.416______________236/232
Skunk 2 Turbo 1:_________.409/.394_____________223/227
Skunk 2 Turbo 2:_________.433/.417_____________231/236
Crower Stage 2 Turbo_____.466/.445_____________233/235
Now look at some N/A cam specs:
S2S2___________________.485/.466_____________266/262
S2Pro2_________________.504/.473______________270/276
Buddy Club Spec III Plus___.449/.465_____________296/290
Do you see the difference?
I think that almost $600 is a bit pricey for a set of cams that's so close to the GSR/ITR combo. I like the specs on the Crowers, but I don't know if they would be appropriate for a B16 and they do have a lot more lift than any stock cam, so I don't know about using an OEM valvetrain with them (Crower recommends against it).
