Hi there, I'm just wondering if any body 100% sure if the crank pulley of GSR (B18C1 engine) is the same with other B18B engine off the integra same generation??? Are they the same? And also, is the GSR (B18C1 engine) crank pulley is the same with civic SiR (B16A2 engine)?? Please let me know ASAP, I need to clarify it. Thanks a lot guys.
