1/ cylinders, or torque? = 1.6 100kw

2/ Auto or Man = auto

3/ Tyer Size = 42

4/ Trans case gears = duel lux

5/ Diff ratio's = 4.5

6/ What you use it for? Touring, Winch events, Rockcrawling = all terian rock

7/ RPM @ 100klms in high range, (May not be applicable to some) = nope

8/ Anything else you think is relevent. Too low? Too High? Just right? Too much RPm at 100k's, etc. = crawl is 54.87 but may need to make lower eventualy.....

1/ 4cyl 3.4l Diesel (3B)

2/ 5 Spd Man (H55F)

3/ 33x12.5R15 Jungle Trekker ]['s

4/ 1.959 (STOCK)

5/ 4.11:1 (STOCK)

6/ Daily Driver, camping, moderate wheeling

7/ 2750RPM @ 100kph on 31" Cooper AT's. probably about 2800RPM @ 90kph on 33" JT2's.

8/ Could do with slightly lower low range gears. I can't use 2nd as much as I used to on the 31's when wheeling on 33's.

4.9 (H55F 1st) X 1.9 (low range) X 4.11 (diff gear) = 38.26 crawl

1/ cylinders, or torque? = 4 cylinders and a tightly wound rubber band
2/ Auto or Man = manual 5 speed

3/ Tyer Size = 31 road , 33 play

4/ Trans case gears = trail tough 6.4

5/ Diff ratio's = 3.9

6/ What you use it for? Touring, Winch events, Rockcrawling = crawling

7/ RPM @ 100klms in high range, (May not be applicable to some) = around 4000 ... (dont have a tacho)

8/ Anything else you think is relevent. Too low? Too High? Just right? Too much RPm at 100k's, etc. = ratio is good for the 31's need a little lower for 33's .... highway use is annoying as hell and most likely why it chews the gas (200K's for 40 litres)

its a zook thing
