gearbox was designed to cutoff 1st gear at ard 7.3k rpm approx and not at 8k rpm as ratio were too short. for that you need a ecu along with a engine.
sergtr is right in his statement, ae-101 came with st20v. ae-111 had bt20v. rest i dont know how that engine got into ae-101,, only one answer, japanese are capable of good quality swaps.
anyway coming back to topic,,, good luck with sale.
