long time lurker here--rebuilding 1.6L NA to turbo for 2 door MK1. Lightweight car with objective of MPG and some performance. Am thinking of having transaxle rebuilt with taller 5th gear for reduction of eng. revs and subsequent increase (hopefully) in MPG. Does anyone know what the tallest 5th gear that can be easily swapped into a 82-84 transaxle. I think its an 02A but am not certain. Thanks!
should be an 020 tranny. however you can install an 02A with some mods if you want some really tall ratio's
tallest final is 3.67. tallest 5 is .71, found in ff and fn boxes .
Thanks for the assist! It is much appreciated. Now to find a .71 fifth gear and a shop to do the work. Really do appreciate your help--this site is an addiction...
