Just came across this engine and this information was very helpful, thank you… the engine was not utilizing vtec with the ecu in this vehicle. It was in derby and endurance race; the engine overheated multiple times. Will find out soon what needs replaced to bring back to life.

The 3 stage has 5 lobes per cylinder on the cam shaft 2 lobes for the exhaust and 3 lobes for the intake. One small, one medium and the high lift lobe, your schematic at the start of the video was of a 3 stage system with two locking pins. Stage 1 only opens one valve just off the seat to prevent pooling of fuel on the back of the valve and the other valve runs of the medium lift lobe, Stage 2 joins with a pin locking the 2 intake rockers together actuating both valves off the medium lift cam lobe and Stage 3 has another pin that locks the rocker arms to the large centre roller rocker that is running on the high lift lobe. Your engine only had 4 lobes 1 solenoid and 1 pin per cylinder so 2 stage .

In your video it has only one vtec solenoid. 😃😃 How can be 3 stage ?. This is vtec e. 3 stage setup totally different.

Correct me if I'm wrong but I think this is vtec e, those two camlobes that were aligned was for exhaust valve. Vtec e always uses the vtec lobe, the only difference is that when in low rpm, the head only works with 12 valves, 4 intake and 8 exhaust. Now when on higher rpm's the rocker arm locks all the valve and now it operates on 16 valves, 8intake and 8 exhaust. The round camlobes was used to open the valves slightly on low rpm's. This is how vtec-e works compared to traditional vtec... Nice explanation btw 👌

At first I thought that this was NOT the 3 Stage VTEC engine because I have a 1998 JDM D15B OBD2A VTEC swapped in my 1990 Civic and mine has 2 VTEC solenoids. But after doing some research the one in this video looks like the 2001-newer D16W7 VTEC-E or the D16W9 3-Stage VTEC. I found two websites that say the D16W9 has 3-Stage VTEC. However it looks like it only has 1 VTEC solenoid valve. As someone who understands electronics well enough, you can use one solenoid valve to control two separate positions if you reverse the polarity (-neg and +pos) So it is possible that this is actually a 3-stage VTEC engine. I'd have to look into it more. Does anyone else know more about the D16W9 engine?
