VTEC is an intelligent design that produces better gas mileage, more power, a smoother graph, and more efficiency. It is not like a bolton...it is a characteristic of an engine that gives great benefits, which are greatly expolited with significant modifications. Look at a graph of a heavily modified NA motor, or FI for that matter. Disable VTEC, and examine the same graph. More than a few HP. Granted some loss will be due to the different af characteristics, but the power is lost, regardless.
BMW's VANOS, Toyotas VTTi, etc etc...every car manufacturer has a "VTEC."

Vtec is great, but a lot of people make it seem like its the greatest thing out there. Honostly, its more like a bolt on. Like if I was to put an aftermarket TB on the car and help it breath a bit better and in turn gaining like 5hp. Vtec is the same. Think of it like an aftermarket head that help get you an extra 30hp (for the integra). And just like every other mod, do you get sucked into your seat when you put a header and exaust on? No. Can you hear it? Yes. Can you feel there's a difference? Yes. But its not gonna be so noticable that your eyeballs get sucked into their sockets.

Thanx for the input guys.
The general idea (or myth?) that a lot of people gave me about VTEC was that it acted like some kind of turbo. The first VTEC ride I ever got was on a S2000, and believe me, the car flies past 6000 RPM. Also, a lot of thread about RSXer at www.clubrsx.com describe VTEC like a surge of power and noise when VTEC engages. They also describe the VTEC of a GS-R being more severe than a RSX type-s:/ My assumption was based on that.

Rsx's have The i-VTEC system (the "i" stands for "intelligent") combines Honda's patented VTEC system (Variable Valve Timing and Electronic Lift Control) with Honda's cam position-adjusting VTC system (Variable Timing Control) to enhance low rpm torque while extending high rpm horsepower. i-VTEC = VTEC + VTC
Since the GSR has a less refined v-tec system the "surge" of power engages in a smaller power band of 5300-7900 Rpms, unlike the RSX with a much wider power band whereas the vtec is distributed almost throughout the entire rpm range.
The reason for this "surge" of power or quick transition/ activation of vtec is because it kicks in at such higher Rpms. While the Rsx's vtec has been activated much earlier and because of the VTC it is smoother throughout the rpm range, which makes it a lot less noticeable.
I can definitely feel my v-tec. The point where Ican feel it really kick in is around 6000Rpms.

and vtec kicks in at 4400 on gsr's. intake secondaries are at 5800.
