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.

I think the old phenolic spacers may be homemade or induction system specific. No telling what was done to the heads to make the manifolds fit. Try a set of CB tall manifolds and see if they fit.

Can you take
A picture of the head? Intake ports, I mean.

Also, your engine tins might have been modified .

forget the bolt hole spacing, the ports are much closer together. Not sure how you could modify heads that much ???

Here you go - some funkiness on either side of these ports I hadn’t noticed before (first time taking the fuel system off).

They look a little like Okrasa T1 heads, but hard to be sure from that close up shot and I haven't seen any of those heads in years.

Perhaps a pic showing more of the engine would help us identify what you have there.

Never head of Okrasa before, interesting.

It's a Type 4 2.0 case, but heads are different (obviously).

There was some discussion of this earlie - @McMark thinks they may be aircraft heads.

Prior discussion of these heads

I'm inclined to agree with this. Clean it up good, put the turbo back on and run it ...

CBs aren't going to work. The fin distortion on the right side behind the 1/2 of a threaded hole is odd. Is that melted aluminum?

First of all - you guys are awesome.

It's always been temperamental - shocker - to a point where it is a pain to live with. Love-love-love the suspension and brakes (all 911 stuff) so I think I am going to pull it out and put a 2.0 in for now.

Eventually this will get the 3.2 when I'm ready for that.

Once this thing is out I may fool around with getting the intake set up for regular induction after I get a better sense of what the hell it is.

Thanks for all the responses - hope everyone has had a good Sunday so far.

From the looks of it, someone put some work into this motor to make it work with a turbo.

Chances are, regular induction won't work well on it.

Looks like the original spark plug holes in the tin are covered with a piece of metal which is riveted in. There are rivets just above each spark plug as the spark plugs exit the tin right with the intake.

Looking at the image of the heads, it looks like at one time there were 5 studs, or at least the 2 studs on the ends were used at a different time, and is no longer the case?
