VTEC engines can control their valve timings differently depending on the driving conditions. the timings can vary

are you asking what's the difference in the ENGINE between the Honda VTEC Vs. Acura VTEC and Honda Non- VTEC Vs. Acura Non- VTEC.or BODY style difference in Honda/Acura VTEC Vs Honda/Acura Non-Vtec?or just VTEC Vs. Non-Vtech? vtec is an electronic variable timing control . the computer decides whether you are driving fast or just crusing. if you are driving fast than it will help preform, if not than it will help with MPG improvement./

There is a difference in the camshaft and how the lobes open the valves.

Vtec stands for Variable Timing Electronic Control. It is where the engine can increase/decrease valve timing at certain RPM points pre set in the engine. If it is i-VTEC ten it has timing gears instead of a timing bellt and has adjustable torque as well as adjustable horsepower.

a vtec engine has a more advanced computer onboard for the vtec system, now the vtec works like so, you know how muscle cars idle low, you know blugh blugh blugh thats cause the cam is offset or retard,now on a honda vtec it offsets it selve by movemnt of the cam it can be for high rpm or low.a non-vtec only has one cam position therefor non-vtec,plus vtec would be on the engine or decaled on the car somwere
