Anyone know what this manifolds off

same flange as a14/a15 but ports are huge, from wikipedia the only thing i can find that comes close is the a14 gx but gx ports are still a bit smaller than these.

cant see where they have honed it out stil has casting marks showing, went in to the turbo shop today and guy in their reckoned it was from a15 gx thought their was only a12 gx and a14 gx,

asked guy on trademe what size his ports are, same as mine. http://www.trademe.co.nz/Browse/Listing ... =268012663" onclick="window.open(this.href);return false;

I'd say it's for an A12GX motor. They have bigger ports than the standard A14/15 heads.

a12 gx have 30 x 35-36mm ports their would be a lip using this manifold. bit of a bugger if it is. cheers.

that guy on trademe auction reckons his manifold is for a15, kind of went back around on my question, this looks like the only one redline make for a14/a15

and trademe guys manifold has 30 x 40mm ports, maybe you can put these on, thought atomised fuel would pool if ports were not exact match.

thanks for your pictures, do all the a15 heads have the multi stud pattern to fit both types of manifolds?

found a picture on an a15 h89 head with 36mm ports,

I'm not usre that ALL a15 heads do, but it's not a mission impossible to drill and tap the extra hole.........
