Honestly, most of the turbo VTEC people I know swear by GS-R cams. ITR/CTR's have lots over overlap that needs to be dialed out to make maximum power. GS-R cams are very easy to find and cheap to get in most cases. I'd stay away from the "turbo" cams for VTEC engines. Over GS-R cams I doubt you'll see that big of an improvement. $600 is a large chunk of change to drop just on cams. With the much you could buy rods and pistons.

I myself run turbo cams, but then again i've got an LS engine, the stock cams are ass on LS engines.
