    I'm not an expert on forced induction, but generally speaking you'll want a wider lobe separation angle to reduce overlap and keep your intake charge from blowing out the exhaust valve. Also, more duration on the exhaust should help evacuate the cylinder against the restriction of the turbo.

    Check out Thunder Racing to see what they have. The "Old Man" cam is a good starting point at 214/220 .600/.523 115 LSA.

    Up from there, the "CheaTR" cam offers a lot more exhaust duration at 214/230 .601/.578 117 LSA, but could be a little much for a turbo.

    They might also suggest a custom grind in the neighborhood of 218/224 or a 224/230 on 116 LSA.

    Good Luck!

    I agree with Hammertime.

    Another option that has reputedly worked well is the LS6 cam (204/218/118/.551/.547) and something along the lines of an LS7 cam would probably be reasonable also (211/230/118 .600ish/.600ish). A real LS7 cam won't work with your engine but a grind along those lines would work.

    You guys are recommending good supercharger cams, but a turbo is going to like a reverse split cam. You'll want to keep the overlap at a minimum like the cams above, only use a turbo grind with more intake vs. exhaust duration.

    will it work, yes. like most have said, best to get it on a 114 LSA. that way, you don't bleed off some of the added boost by letting it escape out the exhaust. along with getting a reverse split cam. most turbo applications benefit from it.
