I've had my built/turbocharged LS/VTEC running for a couple months now and I'm looking to upgrade to better cams. Right now I'm running GSR cams because a friend was selling them at the time for a decent price so I figured they'd be a decent improvement over the B16 cams that came with my head.

I've done a lot of research on the characteristics of certain cam combinations but it seems that there are only two directions to follow: turbo cams or N/A cams. By "turbo" I mean high lift/short duration vtec lobes and "N/A" I mean high lift/long duration vtec lobes. What I was wondering is if there is a cam set out there that sort of combines the two and would allow me to take advantage of the fact that I'm running a Full-Race-style exhaust manifold and cam gears. Right now my spool-up absolutely blows before VTEC (which is set at 4400) with a t3/t4 57 trim. This is because of the low lift non-vtec lobes. When I was running a straight turbo LS, the spoolup in that rpm range wasn't bad at all because of the much higher lift of the LS cams. I'd like to improve the VTEC lobes as well, and was thinking about getting type r cams, but those have the exact same non-vtec lobes so the spoolup would be the same.

So put simply, is there a turbo cam out there that has higher lift/shorter duration non-VTEC lobes (similar to an LS profile) and basically Type R (or slightly better) VTEC lobes?

CTR cams + adjustable cam gears

That's what I'm gonna be doing, although using N/A cams on boosted apps is really starting to gain popularity. If you check out the sponsored forced induction market place there is a company called mazworks or something like that. They just released a cam combonation that has crazy power. It's basically a JUN Stage 2 intake cam and a Skunk 2 Stage 1 exhaust cam. They gained up to 96 whp on some of their cars. The only thing is, the pair of cams costs like $500, but if you have the cash I'd say go for it (keep in mind you'll need to upgrade your valve springs and retainers as well).

CTR's don't take care of the wussy nonvtec lobe issue though.

I'll look into those Mazworks cams. I'm more concerned with spoolup on the nonvtec lobes and good topend on the vtec lobe. I would be perfectly happy with ITRs or CTRs if it weren't for the lack of good spoolup pre-vtec.
