For most applications the water manifold above is what works best in rear engine sandcar applications. This is a modified manifold that bolts into place using the OEM orientation. Outfront's re-engineered water manifold (shown above) routes the exit hose to the area just above the clutch arm on the bell housing. Modified water manifolds on a Subaru can bolt onto the block two different ways, one of which is turned around 180 degrees from stock orientation. Although this fits OK mechanically, the thermal characteristic of a reverse orientation has never been studied at length to confirm equal water flow between heads. If you study where the water is pumped from on the right side of the engine, it's questionable whether the reverse orientation provides equal water flow of water on the left side head bank. Because of this Outfront recommends keeping the manifold oriented in the stock orientation. This insures the engineering that was done in Japan is taken advantage of to keep both banks of cylinders equal in water flow and temperature. Below is a picture of a stock water manifold, best suited for most mid-engine applications. This stock manifold only works when bolted on in the OEM orientation, it cannot be turned around 180 degrees because the exit pipe will hit the head intake port. This manifold dumps the water near the power steering pump to the front of the engine (opposite bell housing).
