1999 Patrol GU Y61 Diffs

[Engism]

OK .... I have fitted the 5.13 crown and pinion gears (Nitro) in place of my original 4.625 ratio,s in my Y61 RD28 with BFG All-Terrain T/A 265/70 R16 Tyres and couldn,t be happier with how the truck now performs. For anyone interested the speeds and revs now in 5th gear 2WD are as follows:
60 Kph (Gps) = 1800 rpm = 68 Kph on original speedo
70 Kph (Gps) = 2100 rpm = 80 Kph on original speedo
80 Kph (Gps) = 2400 rpm = 92 Kph on original speedo
90 Kph (Gps) = 2700 rpm = 103 Kph on original speedo
100 Kph (Gps) = 3000 rpm = 116 Kph on original speedo
110 Kph (Gps) = 3300 rpm = 128 Kph on original speedo
Now in 4WD Low the truck is a delight in the bush .... I also placed a stiff sponge under the throttle pedal after another posters suggestion to fix the sensitivity of the Fly By Wire throttle pedal system and it has completly stopped any of the normal sensitivity that caused the jerky throttle response in the rough .... over all the machine is exactly how I feel Nissan should have set it up from the factory ... very happy camper.
