Gearbox Ratios

Mods: Can we make this a Sticky?

I keep seeing lots of incorrect ratios flying about for various boxes, so it may be helpful for people to have a list that everyone can refer to:

This is my most up to date list at the moment.

Cheers,

Marc

This may help a little

Nice one Dino.

Is there a model in the Honda range with a higher final drive that we can swap to lower the gearing and increase acceleration?
M Factory 5.15 looks fantastic, but they go for $900!!!!!!

Cheers

Kai.
4.266 Fd is the highest that i know of. Otherwise its aftermarket Final drive or H2B conversion for a larger choice of ratios.

m factory final drives do not work with factory lsd's so you would have to install an aftermarket lsd as well

They dont work with viscous lsds that the prelude has or the ATTS boxes.
It will work with ATR U2Q7 box as this is a torsen type diff similar to Quaife LSD.
