hey guys I am almost done putting a zc motor in am 89 crx si. I cannot find the nipple on the manifold for the brake booster. Is there one? or do I need to tap a hole and put one there? any info wold be great thanks.

 

It's there on mine, maybe your's was broken in shipping? Should be on the lower part of the drivers side of the manifold, little 90 degree bend. If it's not there, you may be able to extract one from an Si manifold and reuse it with a bit of sealant. Here's pics of my install.
