VTEC Engine and the 4-stroke engine. There are four strokes in a 4-stroke engine. These are intake, compression, power, and exhaust. The piston works downwards in the intake stroke, and the air gets into the cylinder compartment of the engine. In the compression stroke, the piston works upwards and compresses the mixture of air in the cylinder. VTEC stands for Variable Valve Timing and Lift Electronic Control. It’s a proprietary system developed by Honda to make a four-cylinder engine more efficient. VTEC engines get better gas mileage at low rpms and deliver better performance at high rpms. In this article, we’ll try to explain what a VTEC engine is in layman’s terms. MrClean228. New Member. Sep 8, 2012. #7. I actually did the same swap myself. I had F22b2 and Coverted to F22b1. I found that the distributors are different. The coil is built outside of the distributor on the b2 and on the b1 it is built internally into the distributor. Use your old distributor and coil from the b2. q0up.
