I just got this crank from a guy since mine was bent . he told me it is a JDM B18C TypeR crank. but i have no way of tellin.

I do notice that :-

there is a "S" on the second weight from the pulley side.
The weights in the middle are thicker and dont have the concave shape like the GSR.
and there is a "h" on the last weight by the flywheel side.

please help me figure out if it is indeed a TypeR crank or a B16A crank or LS or what ever

the pics are here:

well, i will tell you that whether it is a "jdm itr b18c" crank or a us itr or a gsr or a usdm gsr makes no difference. so, most individuals that know what they are talking about would say its a "87.2mm" crank. its called character analysis my friend. you can usually tell what a person is all about before the 5th word flies out of their **** holster (mouth).

 

ITR cranks have a "R" stamped on them.
