The engine doesn't have potential, so get a swap, like he said. Vtec controllers don't give you more power, the timing is already pretty close to as good as it can be. 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. This type of design is worse in terms of fuel economy. But lower in complexity when it comes to implementing the VTEC system. As we noted previously this type of V-TEC is using two profiles and hydraulically selects the profiles based on the engine RPM. Similar to any variable valve timing system. Overhead cams are designed with the camshaft placed over the cylinders. The term "single overhead cam (SOHC)" refers to a bank of cylinders, implying that the SOHC uses only one camshaft on the in-line engines. Two-cylinder banks are available on V pattern engine blocks, making it possible for the engine to feature a total number of two VTEC ® was the first commercially successful variable valve timing and lift technology used in a production car. VTEC has evolved over the past 30+ years to provide multiple benefits, including increasing horsepower and torque, and improving fuel efficiency. The technology remains a key component to Honda’s enthusiast appeal. Now you will need to convert your existing harness to plug into this new OBDI distributor. You can do this one of two ways, either put OBD0 plugs on your new distributor, or put OBD1 plugs on your engine harness. We prefer the second option, as that leaves your new distributor stock and resellable should you decide to go that route. If so, look at the 8th gen dyno from hondata. Look at the massive spike. The 9th gen doesn't have that. The 8th gen didn't have an integrated exhaust header into the head, and it also had vtec cam lobes on the intake and exhaust side. The 9th doesn't. Mar 29, 2015. Staff. #3. 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. .
