ls-gsr swap, guage cluster question

i'm planning on swapping a b18c1 into my 93 rs integra, for the guages.. what could i do to make sure the tach is accurate and giving me the proper redline readings. once i swap the motor in with the new ecu, will it make the needle move like stock (4500rpm@4500rpm) or will it read like the tach on the gsr where it would look like to me that it's at 4500 rpm where it's actually at like 5400 or something... what would i have to do to get the tach to read the correct numbers? completely new guage cluster or would i just have to replace the faces on the guages to the gsr spec ones. also.. are there faces that are made in kph rather than mph readily available(i'm in canada so everything is in kph)
thanks

no suggestions from anyone?
