... but how many 1994 Nissan KA24E, 2.4-liter, water-cooled, fuel-injected engine, 4-cylinder in-line, overhead camshaft with 2 intake valves, and 1 exhaust valve per cylinder engines are there in the world?
I think they just mock up the cam box, not the whole engine. Nissan parts distributors must be saying to Corporate, "gee we got a problem with these cams! Better make them harder so they wear 4x better!"
