On the intake side right below where you put the 1/8pipe fitting that plugs the vtec oil passage, you will drill and install one of the dowel pins and do the same on the other side at the exact same point. 5. Timing belt. You will use the Ls timing belt if you use the Ls water pump and the gsr if you use a vtec B17/16 or B18c1/5. 6. Head studs. Once the VTEC solenoid in your Honda is activated, it uses oil pressure to push an engaging pin through your valvetrain. This activates the larger lobe of your camshaft, which increases duration and extends lift of your valves. Image courtesy ADPTraining. What this does is allows your Honda engine to run efficiently and with low emissions at Unlike Honda’s VTEC system, which produces noticeable changes in the engine’s power output, the advance or retardation of the valve timing on non-Honda engines occurs seamlessly, and most drivers are unable to detect the change in an engine’s power output if the oil control solenoids work as designed. How Does the Valve timing control go for P28 with Hondata S300. Hondata's a bit overkill depending on how built his engine is. If it's fairly stockish and he plans on keeping it that way, then a chipped P28 with a simple tune for a stockish B20/VTEC should work fine. OP, for some swaps and hybrid builds you can find a stock ECU that will be close enough, but for this setup you The Honda Element features an i-VTEC four-cylinder engine. How does the Honda R18A SOHC i-VTEC work? With the R18A SOHC i-VTEC mechanism, Honda’s R&D engineers introduced the idea of controlling the amount of air entering the combustion chamber via other means instead of the throttle butterfly. This is done via a combination of both valve In that case, the engine will get heated with a little acceleration. Apart from that, lack of coolant, bad radiator, broken water pump, etc., also increases the engine temperature. 4. Sudden Power Loss. If your vehicle is losing power while driving, then it’s probably the bad VTEC solenoid. Ktuner changed it based on ideal performance over the power band. Vtec is intended to account for power drop off at high RPMs, pushing the activation lower would net no benefit, or actually hamper performance. You can look at the power maps from their dyno and see they "did it right". OP. Unline B16, the D16 is relatively weak on the performance side, as the D-Series was designed to be the “economy” focused Honda engine of the time. Production Run: 1986 – 2006. Cylinder Block Material: Cast Aluminum. Cylinder Head Material: Cast Aluminum. Configuration: Inline 4-Cylinder. Once you turn on the engine, the ECU runs a check. If the ECU doesn’t detect a change in the engine’s function, it will know that VTech isn’t working, and it will set the Check Engine light on. So, if you turn on your engine and the check engine light comes on after a while. That could be a sign that VTech isn’t working. IBs7.
