When shopping for an engine, there is a lot you can choose. Based on personal experience,  most people go for VTEC engines. VTEC (Variable Valve Timing and Lift Electronic Control) is a valve train system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine. Basically it makes your car go faster. There is a short list of engines that have VTEC which are D, E, F, H, K, L and R Series.

Besides speed, horsepower and torque there is another factor that you have to take into account when shopping for an engine, where it’s available and legal. A lot of these engines are only available to be in Japan, where Honda is from.

In my own personal vehicle i used a K series engine. the reason was why was that the K-Series engines have two different types of i-VTEC systems implemented. The first is for the performance engines like in the RSX Type S or the Civic Si, this is the one that i chose for my 2nd track car.  The other is for economy engines found in the CR-V or Accord. The performance i-VTEC system is basically the same as the DOHC VTEC system of the B16A’s; both intake and exhaust have 3 cam lobes per cylinder. However the valvetrain has the added benefit of roller rockers and continuously variable intake cam timing. Performance i-VTEC is a combination of conventional DOHC VTEC with VTC.
