Can you tell me (and everyone else that has made it this far) what your current set up is and why you chose the options you did? Engine/trans/ecu/tires/etc? You may have to dumb it down a bit for guys like me though.

Also,and this may get answered in the responses from above, is the HX trans the "new" VX? What is the ratio in each gear? What is your final drive ratio and are there any more options to improve on that or are you "mechanically" as good as it gets? Or at least as good as it gets for being a practical daily driver.

This has been one of the most interesting threads (for me at least) and I don't even know anything about Hondas. I wonder if this could all be put into an early CRX. 85-88 HF's seem to be really light and, not having ever put them into the template, I wonder if the CRX is better or worse than the DX in the aero arena.

I know this would be a long reply (if you even have the time) so I'll just keep checking back. I can't wait to see what your numbers can be after some aero mods. Absolutely great swap and pictures and write-up. Congrats! I'll be watching this one for a long time.
I'll just answer the VX/HX question. The HX is the sixth generation successor to the fifth gen VX, and it has lean burn, vtec-e, and all the other goodies, besides also being OBD2 (the engine control computer type). But the HX had somewhat shorter gearing, a 3.75 final drive and some shorter gears, except 5 I think. Here are listings of D-series honda engine transmission gear ratios.

Also, search this site for VX engine swaps into the CRX... one or two people have done it. Though I would think a better option would be the 99-00 HX engine with a 92-95 VX or CX tranny, swapped into the CRX body. The engine would be newer, OBD2, modestly more power, and super tall gearing.

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.
