i just bought some cams out of a 97gsr there is a small, medium, and large lobe...? Is there a way to tell if these are infact GSR cams? Thanks

 

... they're probably gsr or b16 cams if you didn't pay much for them. I hope you have a vtec motor to put them into.

edit: it's not 3 stage vtec. the small and medium lobes are for low-rpm driving to improve swirl in the chamber for improved gas milage. Then, oil pressure builds and allows the rocker arms to lock together and the big cam lobe then controls the valve actuation.

 

vtec cams have 3 lobes
