HX would have the same gearing and FD as an LX/DX hatch (FD= 3.722:1)
Your LX Sedan has the same gear ratios, but a lower FD (FD=4.058:1)
For all the work you are putting into this car, I think leaving in your LX tranny is being shortsighted. The HX would give you about an 8% drop in RPMs, 5th gen CX/VX tranny would be about 20% drop. |
It really depends on driving style. If this is a long commuter all highway miles very few stops he would see more benefit from the taller gearing and steelies with disc covers
If this is a mixed city and highway driving there really is not much point. City driving you would want shorter gears and the light weight wheels from a hx or vx to require less effort to accelerate.
With my d15b s40 lsd trans on my hx this winter I'm getting 36.8 mpg all city driving. Lean burn kicks in at 52mph and with 45mph speed limits I can usually hit a clean lean burn atleast once on my trips for a few minutes
There is also a thread back in the depths of this forum where a hx member did install a vx trans into his car, I believe he was hoping to turn 2k rpms at 60mph similar to a vx model but noticed he was still turning close to 2200 rpms. He concluded that the trans swap which he intended as an upgrade was more work than it was worth and didn't really net him any benefit.
Lean burn is rpm and speed sensitive on the hx ecu. It only engages in final gear during certain conditions above 2300 rpm or 55mph-78mph. There was also a member who did install a few resistors into his vss sensor to trick the ecu but again I don't recall him updating his posts or fuel log after that
Now if his factory lx trans is on the way out then I would say yes to swap them but he hasn't mentioned that
