Just wondering if anyone out there have stuck a pair of itr cams in a b20z vtec, gsr head and stock internals before or heard of it done. A guy told me before that he had done it and ran with out issue. Lots of people told me itr cams is too big for my stock z piston but they never done it before. So if any one out there have this mod, please give me info. 95 4 dr gsr with b20z gsr head, intake, header, open cat and fpr. email@example.com mph and thats cheap street tires and a slow shifter.
