Hi all hope somebody knows weather this set up will work or will the ratios be too low in top gear to work,
Its my old series 3 109 currently undergoing restoration/rebuild what I've broke on it number 2.
A few years ago i did a 200tdi transplant into it and it went well, but a bit too revvy, so i fitted a stage 1 V8 rear axle and range rover front diff so 3.54 ratio with series 3 gearbox and transfer box, kept off roading and decided i needed bigger tyres so fitted 255/85/16 well you can guess what happened next and bang goodbye gearbox. it lasted well and i knew i was asking a lot of it.
so this time i want to fit a R380 with series transfer box from ash crofts and I've done some calculations and the best i can get it too pull in 5th is 2404 does anyone know if this is too low and will struggle to pull this.
to run through the above clearly it is 200tdi + R380 +series 3 transfer box + 3.54 diffs + 255 85 16 tyres will it work or not.
Everyone likes pictures so heres she is
