how to identify a JDM or AUDM engine :D

[Lex_EG93]

so when checking out jdm b18c's, you'll have to spot the cosmetic differences when identifying the type r and the standard sir engine (like intake manifold - assuming it's still stock)

so what ur sayin is that there are two different jdm b18c's? a jdm ITR and an SIR?
