Any body have any idea as to what motor this manifold is off of? The kid i got it from said it was a y8 mani but i know it's not. It almost looks like a d-15 or something. LMK what you think.

 

Its not from a d15b7. What makes you think that its not from a y8, cause it looks very similar to the ones Ive seen. but, after all, I have a b7 and not y8 so I couldnt tell you for sure.

 

Well I had a '98 EX with a y8 and the manifold looked like this.

 

looks like D15

 

try to look for some markings of some sort if you have it on hand. I know my Dohc Zc manifold has Pm7 written on it...

 

serial numbers or kick rocks!

 

I believe that is off of D16A6
and not: D16Z6/D15B7

Don't hold me to it though.

The d16y8 used it's own version with a larger and rounder plenum. I think one of the skunk2 aftermarket manifolds were modeled after the pgm-fi version except with longer runners, and kept the cylindrical chamber and larger ports.

 

Here we go see if this clears anything up. :-)

 

kinda looks like JDM D15B or USDM D16A6

 

I can not tell. Sorry
