VTec+Turbo? A good match?

I'm not 100% sure on this one to tell you the truth. I see your point too.

Turbo kits are all different. My GReddy T25 powered D16Z6 was fully spooled by 2,500rpm, where as my Rev Hard T3/T04E powered B16A started spooling around 4,200rpm. I, personally, would stick with turbo then VTEC, but it may work otherwise. Bottom line, just make sure they hit at DIFFERENT times.

So this means that if the when the turbo and VTEC starts at a closer RPM that means that you get better throttle right?
eg. Turbo starts at 2,000 and VTEC starts at 2,500 is better than Turbo starting at 2,000 and VTEC starting at 3,000.

Technically, yeah. A ball bearing T3, or a T25, or comparable turbo, will spool very low like that. I would suggest marking where your turbo hits FULL spool, and setting your VTEC maybe, 100rpm later. One right after the other, just to be safe, will give you the best results most likely. I'm not 100% here, the only way to find out would to strap your car on a dyno, but I would stand behind it, one after the other.

The Apexi Vtec controller only goes down to 3000 rpm
