i bought a auto ke70 for like 450 bucks with 8 months rego, i came across a company selling a 4age silver top for 1200 in brisbane, first of all I'm sure i could get one cheaper , but my main question is, if i was to spend money upgrading to a 4age, id obviously want to switch to a manual - what gearbox would suit this application? also what is there in the way of lsd's for ke70's? I'm assuming there isnt such thing , but worth a try :)
