Are you gonna boost it? It's going to be 8.3:1 CR with the Ej22e bottom end. I would use the Ej25 headgaskets on it. This way the coolant passages on the heads will get maximum flow into the heads. Because the Ej22e is open deck, you really just want to make sure the head gasket does not interfere with it, and the Ej22e HG is marginally offset for the Ej25 coolant passages.

where did that thread go anyways. ive been looking for that infoMatt Monson wrote:The compression ratio is more like 7.3:1 Check the stick compilation thread to find the exact numbers with the math.Impregacy wrote:with the 2.5RS heads what compression ratio do people end up with? I heard it was like 7.1:1 and is the engine still non-interference? does the turbo coolent return adapter bolt on to the back of the right side one?
