Well awhile ago I did a Y8 swap into my 91 Civic. I got out there yesterday to do the OBD1 conversion and I noticed that the "97 Civic EX" distributor I ordered off the internet wasn't going on. So after a lot of head scratching I looked at the serial number on the dizzy. Turns out it's a dizzy from a 99-00 SI.

So I'm all pissed and everything and said fauck it I'm going to the junkyard. Got a dizzy from the junkayd, well 3 by the time I found out what was going on, and non fit. So I'm like WTF! I look at the head and it says P2J-1....I previously thought it said 7, but I guess I was wrong. I got to looking into it and it's a motor made for the europe cars. It's a D15Z6, yes D15Z6. Well I figure a Z6 dizzy would fit on, well wrong.

My a6 dizzy bolts right up to it. I was driving it fine with it. Just can't use it for the OBD1 conversion. So my question is are the bolt patterns on the A6 dizzy and the OBD2 96-98 TD80U dizzy the same? I heard they were, but I want to make sure before I fork over another chunk of change.

Also can anyone help me figuring out my compresion ratio. It was a a D16Y8 with 10.5:1 c/r SRP's. Now with this new find, what is it. D16Y8 block with D15Z6 head.

Thanks

 

AFAIK no obd1 dizzy will bolt directly onto a y8 head.

 

...I didn't ask about a obd1 dizzy on Y8 head. I was asking if the A6 and Y8 dizzys had the same exact bolt pattern. I got a D15z6 head

 

You said you were doing an OBD1 conversion so i assumed you wanted an obd1 dizzy that would fit your y8 head. Yes, the a6 and y8 dizzys have the same bolt pattern.
