Think the lower powered engines had the 1.6 tfer box.theres either a 1.4 0r 1.6 in the Ninety as it is, thinking its 1.4 as thats (supposedly??) what the army / LR fitted in 2.5nad Nineties
have Disco sized 205r16 tyres now but did have 7.50 16's (MUCH BIGGER) when we first had it (& that was with the luggish 2.5nad)
it will happily 'pull' ~30mph in fifth gear up a hill now but the smaller tyres and 200tdi probably suit that
