howzit julian, jon c-w, etal,
just arrived back in the uk and thought i'd pose a question to take my mind
off things:
i have a 1994 uk 4runner (model: kzn130r gkmsxw) (frame: 8001855) with the,
non ecu, 3.0 l turbo diesel engine (engine model: 1kz-t) (engine no. 1kz
0453393) and manual transmission and separate (2h, 4h, n, 4l) manual
transfer box. it came with 265/70 r15 tyres, ifs, add on the front axle and
a lsd on the rear. vin: jt111gnd008001855
info plate: c/tr/a/tm: 202 hy11 g285 r150 f
g = 8.0" rear diff (all us 4x4 4runners and pickups)
28 = 4.300 gearing (usual for us at, 225/75)
5 = 4 pinions (lsd)
a gear ratio of 4.300 is the "factory rated gearing" for 225/75 tyres, 4.556
is recommended for 31" tyres so i feel a little undergeared. currently i use
750 r16 michelin xzl's (i have also changed from 15" alloys to 16" steel lc
split-rims), so would you recommend re-gearing to: 4.56 and what
positive/negative effects would this have? would the fuel savings be made
primarily in long distance travel? i hardly ever reach speeds in excess of
110kmh (tar: most of the time: 60-80kmh, track etc: max 30kmh) as most of
the roads i use are full of potholes, so should i bother and is it a
financial reality? would re-gearing allow faster acceleration from a
standing start as my vehicle is very sluggish (it takes a lot to build up
some momentum as my wheels must be at least 40kg each) until it hits the
2000+ rpm band when the turbo kicks in?
