Outer Limits 4x4 Board

A bloke at work wants to put 35s on his mq short, pretty sure it is diesel and wants to keep / improve his low range gearing

He realy wants to do something along the lines of t-case gears but apprently you can't buy any.

What advice can i give him, we have already thought of adapting twin hilux transfers into the shorty

sell it and buy that $5500 GQ for sale on here?

low gearing wasn't that bad with the 35's, 33's didn't even notice it but up to the 35's you will be surprised... it's not that bad

I run 35" BFG MT's on mine and 1st is fine for crawling....will be a bit better when the 5spd goes in but !!!!

I thought all of the ratios were the same as a 4spd except 5th is obviously higher....?????

Two gearboxes were allicated to the MQ Patrol, the F4w81A ( 4 speed) or the FS5W81A (5 speed) ratios are as follows...
F4W81A
4th..........1.000:1
3rd..........1.449:1
2nd..........2.157:1
1st...........3.519:1
Reverse....4.181:1

FS5W81A
5th..........0.825:1
4th..........1.000:1
3rd..........1.440:1
2nd..........2.370:1
engine with turbo
1st..........3.897:1
Reverse...4.267:1
engine without turbo
1st..........4.222:1
reverse...4.622:1

Two transfers are also availiable, the T130A and the T100L
Ratios are......
T130A
High.........1.000:1
low...........2.220:1

T100L
high..........1000:1
low...........2.074:1

Is it possible to tell from the outside which 5 speed you have?

the numbers stamped on the front top edge of the G/box are a code as to what box it is ( right up near where the bellhousing bolts up), other than that pull the sparkplugs out and with a mate rotate the motor in 1st gear and count the revs the driveshaft turns ( put a mark on the shaft)... its the simplist way and gives a fairly accurate reading. or PM me the numbers and I'll check it against the book.

V8, what was the ratios for the 3spd

BTW i thought that the MK's only came in an SD33T but are you saying they still retained the SD33 with the 5spd box?

I dont know about the MK series motor/box combinations but the MQ series 1980 to 1987 ran a couple of different combinations in gearbox's and transfers to both the SD33 and SD33T aswell as different suspension setups/ interiors/seating capacities etc, multiply that by the LWB & SWB and petrol/diesel models and you can see where the confusion starts to set in !
Of my 3 MQ's alone there are 3 totally different combinations, ChevyMQ has 3 aswell and his are also different aswell, even the diff ratios are different in 2 of the 6 MQ's here and they are all SWB vehicles !!!
One I cant figure is the seating capacities of my 3... one compliance plate says 3 , next says 4 and the last says 5 !!!! go figure that one !
As for the 3 spd ???? the bible doesnt have any ratios listed but I will check out a bloke I know who has a full set of microfish on patrols and get back to you.

Thanks V8

Thanks V8Patrol

i will let my mate at work know, and he can work it

which nissan has a split transfer case in it

Gear ratios for the 3 spd box..

1st.....2.900 to 1
2nd....1.562 to 1
3rd.....1.000 to 1
REV....4.015 to 1

Typical transfer ratio(split case)
high....1.000 to 1
low.....2.264 to 1

ok, v8patrol

he already has a turbo diesel gearbox - but he realy wants to be like a hilux and run dual t-cases

is his turbo diesel 5 speed t-case a split type t-case or do they come in another model?
