Okay, So I am looking into a k04 retrofit on an LE5 if you haven't read any of my previous threads. The main concern with bolting the LNF manifold to the LE5 is the coolant outlet pipe from the water pump to the thermostat housing. So to resolve this issue, one would need to swap the outlet pipes between an LNF and LE5. So my question is, the waterpumps in both engines are he same, but the outlet pipes and thermostat housings are different. Could I swap an LNF outlet pipe into an LE5 without changing to an LNF thermostat housing, and if I did have to convert to an LNF thermostat housing, would it bolt up to the LE5 block? They look similiar but are obviously not the same. PLEASE EXPERIENCED ECOTECERS HELP ME!!!
