Try this...Now alot of people doing mini me swaps or attempting to get a dizzy that is off a 1.5/1.6 non vtec injected thinking its got the same plugs so it should work on the vtec 1.6 d16z6/d15b/y8... at first I knew the mounting was different but a drill or a angle grinder can fix that. Just modifying the top notch would do the trick mounting a non vtec dizzy to a z6 head. But I was wrong. Sure it ran and sounded like it was working great, but my check engine light didn’t think so. It detected a cyp error. So I went on a mission to find a cheap z6 dizzy., once found I decided to take them both apart cause no one ever has any documentation about the dizzys compared.
Now a non vtec dizzy can be converted over to a vtec dizzy, just see the pictures below.
Now as u can see in the first picture, the top notch is in a different place, that really means shit cause most dizzys hold by 1 or two bolts on most engines, but you can get out the grinder and modify it to fit.
now comes the serious part, as you can see the cyp which looks like a snail shell is the same but in a different location, when the dizzy is in the opposite direction to the vtec one, the snail hits the sensor,
For the bright people, the snail is 180 degrees out. To convert it to vtec specs, you will need to remove the pin, and regrind the snail, fitting it to 180 degrees (opposite position) once done the cyp will accept the signal, and it will be a vtec dizzy.
