it probably adds the vtec lag to the turbo lag... so when it kicks in you are like wow crazy shit
are you stupid? there is no turbo lag on a stock sr, there is a boost threshhold but there is no lag. theres no such thing as vtec lag either.

eat a dick you asshole, why are you calling me stupid you fuck?

vtec does "lag", why do you think people get vtec controllers? I'll tell you why, its to make the "vtec" start at an earlier rpm and to smoothen out their powerband.

Boost threshhold vs. lag? OK!
 
^ your so freaking agro! Chillout damn. And there is no Vtec lag. Vtev controls valve lift and duration. Vtec lag would be like the computer lagging, and computer are pretty fast haha. Way faster than your POS s13 and bmw m3 hahahaha j/k (it was a joke, do you understand?)

NVCS is better for midrange power. It actually diminishes the effect of lag by flattening the torque curve before boost kicks in. If you ever drive an s13sr equiped car vs an s14 sr equiped car you will notice that the s13 sr will pull more dramatically because the nvcs gives the s14sr a more linear torque curve.

great point/very informative, i have never driven a car with the NVCS.

However, with what i have seen with the vtec on the h22 motor is that it is set by the factory to start pretty late. I have seen the before and afters on the dyno in person.

- maybe nissan was able to do a better job than honda?

IMO Honda has the best Variable Valve Timing out there. Just because VTEC kicks in "late" as you call it, does not mean its "lagging". VTEC does not lag nor have I seen it "lag". They do tests to find out where the VTEC engagement point should be. As in the Integra GSR's VTEC engages at 4400 RPM while the B16 Engagement is somewhere between 5600-5800. The GSR even runs a bigger VTEC lobe at that. So its not "lagging" its just the way its setup. You can change the engagement point for a different powerband. For example you replace the dual stage intake manfold and switch to a single runner intake manifold you have to up the VTEC engagement point. It should be moved from 4400 to around 5500ish. If you dont change the engagement point on that setup You'll loose torque.

Sorry about the explanation, but I feel I had to.
 
Im not sure about VVT-i as I dont know that much about it. i-VTEC adjusts the phasing of the intake cam continuously to better the powerband. The "intelligent" part of it was designed to reduce emissions and help out gas mileage. It does improve power also. You'll notice that some of the cams for the K series motors that come with i-VTEC say that VTC is removed. VTC is the "i" part of it. The VVT-i works similar to Hondas VTC.
