I was having the local shop do a valve adjustment last week. Well when they were done they asked me why i had diffrent cams. I guess my motor came from japan with b17 GSR cams in it. I was just wondering if i should get the B16 cams or if i should leave it be. the motor is stock as of this moment. I have my turbo set up just need to get it on. what cams will be better for turbo?
