usdm & jdm b18c5

[bago'ong billy]

I know someone selling type r motor, and wanted to know how can you tell if its jdm or usdm. All i know is its a 2001 B18c5. I was interested in buying it but dont know how to tell the difference just by looking at it.

its usdm, jdm engines dont have the numbers on the end. so if it was jdm it would just be b18c. b18c5=usdm
