i just want to know what the diffrence between vtec and i-vtec and which one is better to have?

 

VTC - Variable Timing Control. This is a mechanism attached to the end of the intake camshaft only which acts as a continuously variable cam gear - it automatically adjusts the overlap between the intake and exhaust cams, effectively allowing the engine to have the most ideal amount of valve overlap in all RPM ranges. VTC is active at all RPMs.

i-VTEC - intelligent Variable valve Timing and lift Electronic Control. This is a combination of both the VTEC and the VTC technologies - in other words, i-VTEC = VTEC + VTC. Currently, the only engines that use the i-VTEC system are the DOHC K-series engines.

 

so which one is better?

 

Ahaha nice cencoring. Ummm i don't know... I'd say vtec becuase i-vtec sounds too complicated hahaha

 

I-Vtec is more powerful but still retains efficiency. And the engine bay looks shweet!

 

Take it easy on me misha, I am aware of your hatred towards me...

 

I-Vtec is just the new generation of VTEC. its basically like Pete said. its a continuously variable (timing only) system, instead of having to dial in cam gears, it does it on the fly as you drive. though for most higher power setups, they delete the VTC, and hell, for race-only setups, some people delete the whole VTEC function, but for a normal street car, I-VTEC is hard to beat.
