looking at this site the older vtir box the YS1 has similar 1st, 2nd and 3rd as the 98+ type r box and better 4th and 5th
i wanted to swap these into my 99 vtir S80 box and at the same time getting LSD and 4.9 Final drive
thanx for your help
You basically are saying you want a hydro B16A gearbox with 4.9 final drive and LSD. B16A 5TH with a 4.9 final drive will suck on the motorway. Stick with your Vti-r 5th.
