well my buddy has a b16 with gsr tranny, his first gear sorta bogs(slow pick up) compared to mine b16 w/ b16 tranny. the rest seem to be fine. his crusing rpm(100kph) is about the same 3.5k+/- 300. he can chirp 2nd and third. with my setup 50% chirp third but then my clutch is worn. hope this helps.
