Becuase we in the east is where YU guys get yur JDM parts frum when yu want them so badlly, were the middle person persay, yu read a little question and fact sheet and yu think yu know it, but no yu dont, yu need to read a diffrant book.And i would kno this because we dont have last alphanumeric as US hondas do on engines. Real JDM is such as H22A no 1 or 4 or K20A B16A B18A/B/C
F20C G25A J35A i could go on and on, when we have these engines we have to completelly kno about the engine, bot by if it has a 1 as the last digit or 5 (B18C5) cause our engines dont have thatits solelly B18C rather in an R or a GSR
we go by bearing codding and indext coding on the decked part of the block, Oh yeah yur american conterparts arent decked
