Vince had a custom manifold done to fit the Laminova water to air intercooler. But I think it still based on cutting up and converting the factory manifold.
Ah OK sorry, I thought I had seen a photo of one that was welded into the manifold, thought it was yours, but maybe I'm dreaming of the TD42 version.No I didn't! It was made to replace the factory cooler and not touch anything else. Even uses the factory IC mounts to hold it.
Still for sale too
