Here is a photo of a Toyota Sera Engine Bay. It is a 5EFHE engine. Every 5EFHE I have seen so far has no 5EFE or 5EFHE markings. The 5EFHE can also be found in the infamous Toyota Cynos which is the JDM version of the Paseo. Its distinguishing feature is the much sought after ACIS Inlet Manifold with additional intake runners. The main differences between the 5EFE and the 5EFHE are actually the internals (rods, pistons and cams). They both share the same head, block and crank. The JDM versions also run on higher octane fuel. Please guys if you dont have any idea or have not dealt w
