Honda vehicles use a variable valve timing system known as VTEC, which stands for Variable Valve Timing with Electronic Control. Briefly, since this system uses pressurized engine oil to activate the valve timing system, the PCM (Powertrain Control Module) uses a control solenoid to control the flow of oil to the VTEC system. A ring terminal for ground (choose a 10mm bolt nearby and secure it) and 2 spade connectors that go into the distributor harness. You will disconnect your distributor from the engine harness and plug these spade connectors in to the distributor side. The plug will have a blue wire and a black/yellow wire. The i-VTEC in Honda vehicles and the VVT-i in Toyota vehicles are high-tech variable valve timing systems that help boost an engine’s power and efficiency. Honda’s i-VTEC system can automatically switch between low- and high-speed operation, allowing for greater efficiency and lower emissions at lower speeds while providing greater power at Here’s a step-by-step guide on how to do it: 1) Locate the VTEC solenoid on your engine. It should be located near the top of the engine, on the passenger side. 2) Unplug the electrical connector from the VTEC solenoid. 3) Using a pair of pliers, remove the two 10mm bolts that hold the VTEC solenoid in place. Stated from kpro help file: "Do not set the VTEC switch point too low as there will be insufficient oil pressure for the rest of the engine. As a guide do not go below 2000 rpm." "Do not set the VTEC switch point too high as the high speed rocker arm will float on the lost motion spring and damage the valve train. hondaburner95. Banned.

If you want to feel/hear the R18 VTEC kick it's pretty easy. While moving, lightly press on the gas until the engine revs up to 3500 rpm*, right after it revs past 3500, floor it. You will notice a slight pause and then the engine will sound much louder/aggressive and it will pull much harder, a.k.a. "VTEC kick". Vehicles:1992 Toyota MR2 turbo, 1995 Lexus sc300. Posted July 5, 2005. yea, that engine is just for economy, the vtec is just so its not really slow. 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. The VTEC valvetrain optimizes cylinder filling efficiency across the engine's entire operating range. The i-VTEC engine further extends fuel economy while maintaining the same power as the regular VTEC engines. Low-restriction intake and exhaust systems, a 10.0:1 compression ratio and roller-type rocker arms also aid efficiency. Engine Block 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. Stated from kpro help file: "Do not set the VTEC switch point too low as there will be insufficient oil pressure for the rest of the engine.

The VTEC engine was invented in the late 80s by a Honda engineer IKUO Kujitani. The VTEC engine is commonly known as Variable Valve Timing (VVTi). Honda seems to be the only car with VTEC engines, but you will see VVTi, and VVT in most Toyota engines. Nissan calls it Variable Valve Lift (VVL), and Mitsubishi calls it MIVEC. So, how does VTEC work?
