Hey guys just curious if anyone's ever tried a pre-OBD B16A dizzy on their SOHC VTEC engine in an EF in order to remain pre-OBD without having to ghettofy a stock A6 dizzy by hacking off a leg and drimmeling out the timing adjustment slots.

Also I wonder if a PR3 ECU would run a SOHC VTEC engine nicely in an EF as well? I figure gettting a fuel pressure regulator and trimming fuel back so as to not run rich might be better than a V-AFC and A6 ECU.

Thoughts?

I might be trying this in my 1990 STD hatch with it's current 11:1CR D16A6. I've got a free D16Z6 head complete and my shop has a spare pre-OBD dizzy (rare I know) and PR3 ECU. Problem is my Z6 head is in another town right now and I cannot check to see if the dizzy fits.

TIA!

 

If you use a Y8 head you don't have to cut or modify the distributor at all.
You only need to modify the D16A6 distributor if you bolt it to a D16Z6 head.

The PR3 will run the SOHC VTEC, but you will get a knock sensor code and you will most likely will have to run 2 separate O2 sensors to make it run smoothly.
I would not do it.

"cut or modify" makes it sound like there is real work involved. I have a 1990 CRX SI with a 1994 D16Z6 in it. I used the crx dizzy, honestly, i just dremeled out the top tab and if fit right on. We used the top tab, the other two have bolts that aren't connected but are just holding it in place (not in the dizzy). it's fine with one tab IMO. i say go with the y8.. it'll be much easier.

also, i'd like to know more about this 2 o2 sensors you speak off? what are the conditions of that?

 

PR3, PWO B16 dizzy, the 90-92 integra dizzys, 88-91 civic/crx Si dizzys are all the same

u can use them on ea / other engine and it will work

u can use a PR3 or PWO ecu on a SOHC VTEC but u would have to chip it to reduce the 8200 redline to avoid any over rev and fix the codes away for second O2 and other xtrra sensors

Well I know for a fact that they are not all the same or else you would not have to cut an ear off and drimmel the D16A6 dizzy and 90-91 Integra dizzy to get them to bolt up to a B16A head. The VTEC solenoid sits directly in the way of one of the ears on the non-VTEC distributors.

That's why I'm asking in the first place if the first-gen B16A dizzy will bolt to the SOHC VTEC head. If I do that and it does fit then there will be no modding of any distributor such as when you use a non-VTEC dizzy on a VTEC head.

Oh well I guess I'll just have to go and get my VTEC head and test fit it since nobody else knows.

u just didnt get it

all those dizzys are electronically the same
u can miss and match them on motors... because they are OBDO and work on each others cars due to being same OBD

now , the fact that the legs are different and wont actually bolt every leg to ea others head, is the fact of course that they are different motors.........
bottom line: u want a dizzy that will bolt directly to a Z6 and u dnt have to rig anything, go OBDI and get a P28 Dizzy......
if u just worry about making the engine run, u will ghetto rig any of the distribuitors to the Z6... i have a Si dizzy in my Z6 with a leg and half and i have no problems....
