I have a 1st gen b16 with the trany in my 90 teg i was wondering if there is a way to swap out the fith gear so i can keep the first 4 gears for speed but have a longer 5th for freeway driving. It killing me on gas to be running around the freway on the verge or in vtec for an hour at a time, so if it can be done what gear should I/would I be looking for thanks.
