JDM B18C Type R and SIR Block markings??
I need to know if the JDM Type R block and the JDM SIR block have the same P72 casting mark on the back of the engine block. I know both will have B18C stamped on the front; unlike the USDM blocks which differentiate between the Type R (B18C5) and the GSR (B18C1).

GSR and ITR share the same casting. The only thing I can really think of different in the block are the pistons. All the differences are in the head.
