What Old Mech said in the previous post. And also, a 1992-1995 vx/cx transmission would essentially shift your current rpms in 5th to 4th, and 4th to 3rd (almost exactly). Downshift and you'll get the same acceleration characteristics, but then you have 5th gear down near 2000 rpms at 60mph for cruising. This is my setup right now in my DX civic. At times I cruise at 60 mph getting over 70 mpg, but on average in mild weather I top 60mpg at steady 60 mph without even trying. I should run a test, using my current 4th gear and 5th gear in an ABA pattern experiment to show the difference in mpg the gearing makes.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
