it depends on the end decision. if N/A b16 and type r have the same gears and a 4:40: final drive but the type r is lsd equipped and both have you banngin the gears and pullin hard. turboed now on the other hand gsr is an exellent choice, but an ls has longer gears and you can run it out further on the streets. i now have a type r and it is a nice tranny, but you better be on your game cause 1st,2nd, and sometimes 3rd are close together and if you spin and dont know how to baby it out tha hole it can fall on its face in second. so make sure its hooked a starts pullin b4 you shift.
