im putting together an ls-v and i was wondering outta the oem b series cams which is the best, i know my buddy had an itr intake cam and gsr exht cam. he said the only cam of the itr that was diffrent was the intake. but anyway i have a set of jdm b16 cam and a set of jdm gsr cams. which would be better???

 

The GSRs are larger and will alow more airflow. I figure it's a no brainer since you have the larger displacement and higher compression to support the bigger cams.
