Awww crud - mystery heads, can anyone help identify these? Options

[Tdskip]

So I pulled the turbo intake and single Weber off the red car yesterday, that was discussed here Removing turbo set up

I went to put the dual Weber’s back on and there is no way it will bolt up. The bolt holes and spacing don’t line up. Looks like the heads on there have a significantly larger intake port and bolt spacing is different.

Blue is what I took off.

Red is standard 2.0 intake.

So in the next episode of my ongoing series entitled “this might be a bad idea but...” what if I bypassed the turbo altogether and just connected the Weber to the intake Y manifold as shown in the red scribble?

That would have it set up like the more common (but admittedly not ideal) single carb set up.

I’d get rid of the unnecessary S shape, and since this set up isn’t worth anything to anyone else (unique to put it mildly) so I really have Inc to loose? The Weber wouldn’t be altered.

One last time, before i remove myself from this thread.

From the looks of it this was a custom build that included changes to the internals of the engine itself. Those heads are obviously not your typical T4 heads.

Chances are this engine was purpose build for the turbo. If that is the case, removing the turbo and running it off a single carb will give you horrible performance.
