hey guys i just picked up my turbo from a friend and he told me it was a t3/t4 but i know it has a t3 flange but the compressor i am unsure of...how can i figure out which it is to order the rebuild kit...or will the t3 and t3/t4 kits be the same?? It came of a nissan 280z it is a .63ar and i am unsure of the trim but it is believed that it is a .50
