Transmission Upgrade/change
If you are starting from scratch with a 5 or 6 speed box, you should
be able to get both a lower first gear and a taller top gear. This would/should prevent the need to change the final drive ratio. Best of luck. I'm sure many will be interested in how the conversion turns out.
