The S14 water neck will have a place to bolt the turbo coolant return right where it bends 90*. Look at the pic of Mattback's car in the "S14 blah blah S13" thread. I'll bet it's the same one. The slope in the back is the tell-tail S14 sign. That and the intake plenum is on top, and there's a lump on the front of the head for the VVT.
