I need to add a water/meth nozzle to my system and would prefer to drill and tap plenum just post boost hose.

Is there enough 'meat' to tap a 1/8NPT hole WITHOUT having to have a boss welded on?

Id rather NOT go down that road unless absolutely necessary!!



Anyone drilled/tapped the plenum and could advise or anyone know what the thickness of the plenum material is?


TT

I have a plenum already fitted with plugs for this very mod if you want to swap assuming yours is std and no painted or powder coated? Can send you pictures later
