How can I tell the Vtec Engagement in a d16z6. Thread starter Dnguyen92 Start date Sep 23, Dnguyen92 New Member. Hello, I have aa 92 eg cx with a d16z6 swap. Why the guy went from a stock sohc to another sohc, I have no clue. But How can I tell if it's even engaging? When does vtec typically engage in a d16 and what possible problems could cause it not to work?

I know the easiest way to tell is from listening the header and exhaust when you're driving but I was red lining yesterday and I honestly couldn't really tell the difference.

I was reading in another thread that if you're going past then you're in vtec but that doesn't seem very high in my opinion. I was red lining at 8k's yesterday so any information will be greatly appreciated. Because it went from 90some hp to And the z6 is cheap and drops right in with stock mounts.

Three good reasons to swap. Solenoid might be bad, make sure the P28 ecu was swapped in with the motor, although if it's hitting 8k I would guess it is. Some VTECs crack harder than others too.

But yeah I was looking on like wiki and they said vtec for d16's is around There really isnt any different sounds when I'm around that area on the rpm tho. How do i make sure the correct ecu is with the car? I got it from some mexican guy, he said there's a gsr ecu and its mounted on the passenger side..

If your VTEC isn't working your car should throw a cel code once you hit higher rpms while driving it. You could just pop the hood and rev the car with the throttle body and have your finger on the vtec selanoid and when you rev up past a certain rpm the selanoid should click, if you feel it click then vtec is engaging.

FLounder power hungry VIP. I've seen vtec hooked up to a button and seen vtec engage at idle it is possible for it to engage while the car is not in gear but reved up to the rpm where it is supposed to engage at. Click to expand I'm not a hack i'm saying i've seen it before they just did it to see what would happen lol.

I really don't know y they decided to put it on a switch but they did and it worked. And mine deff did hit vtec in neutral it was a y7 block with a d15b head and a d15b ecu and it would hit vtec sitting still and my friend had a hatch with an obd0 ecu and it would hit vtec in park.

I had the d15b with the obd1 computer and it did have vtec in neutral and yea vtec won't engage at all if the car isn't warmed up or if it doesn't have oil in it.

But i meant vtec was on a button not a switch, so he could be driving and push the button and vtec would engage you could tell that vtec engaged too it got faster but only if you hit it at the right time if you hit it to early the car would like bog down.

I checked to make sure vtec worked on my car by simply reving it up and holding the vtec selanoid. Actually no it really doesn't matter i get negative repped doing the same thing other people do so i don't see the point in trying anymore.
