the japanese engine codes have alot more information about the engineering of the engine than the american displacement numbers do. dont get me wrong; i love all things fast, but i prefer imports for mainly the gas mileage and the light weight. i love classic cars, but something, lets use as an example, the nissan sr20det, has alot more information than, let say, the chevy sb 350

lets look:
nissan:
sr=engine family, kinda useless
20=displacement in liters, 2.0 liters
d=dual overhead cam
e=electronic ignition
t=turbo

sbc:
350= 350 cubic inches....

cams? valves? carbuerated? pistons? anything else? nope.
i only know the answers because i pay attention to all of types of engines, domestic and imports both.


its not that difficult to educate yourself on these engine codes, they really arent that complex and you only make yourself look ignorant by calling the engine codes unsimple.
