Okay here is my situation. Im really leaning toward getting the HKS step 1 cams for my 96 nissan 200sx ser. However im a bit confused as to which ones to get because information seems contradictory in the forums. I'm assuming ill need the s13 cams but im not sure, are the s13 cams the correct application? Also, in regards to shortening the pin on the exhaust cam, how is this done? can that be done at home with a grinder or will a machine shop's help be neccessary?
