I was looking for info on tapping oil lines for turbo install and i came across an article for an oil pressure guage install on an H22. The guy used a port somewhere under his distributor on the h22 head. A hex wrench is needed to open it up and he tapped it for the sending unit. Now I read the turbo guide (several times) and know how to tap the sending unit on the back of the block.
I looked under the distributor of my G2 and I saw the same ports. we have 2 infact, and I was wondering if these can be used for turbo oil feed as well or is it only good to drive an oil sending unit or maybe use both ports.
I was just wondering if anyone know what ports I am talking about and has anyone tried using it for turbo oil feed? Also anyone know what size that port is?
