Gsr?

could someone explain to me what GSR actually stands for. And why does everyone want one in their honda?

GSR is a trim level for the Integra like EX/LX/SI/DX for the Civic. The GSR is the only other Integra other than the Type R that has a DOHC VTEC engine (B18C1 1.8L) which lays 170hp (USDM) and 180hp (JDM B18C).
The reason that the GSR is the preffered weapon of choice is because the trq numbers are higher than the B16A (USDM Delsol VTEC, and JDM Civic SiRI/II) and at the same time is significantly cheaper than the Type R engine.

thanks for shedding some light on that
