I'd like to know if eco-modder members are interested in custom 5th gear ratios and for which vehicle?
There is a possibility that custom gears could be machined if we can get enough interest in a particular transmission and get a group buy kinda thing going.
My first vote would be for honda D-series transmissions, should work for 1992-2000 years and maybe 1988-91 depending on which trans. Maybe shoot for ratio's in the high .5XX's?
I know there's gotta be some Miata and Protege5/Mazda 3 owners out there that would be game, which may also cross over to Ford products as well.....
I'm sure this place could make them:
