you should pe able to change the gearset to one from another 71c easy enough, plenty of silvia boxes and stuff around

Anyone know if the 1st gear is interchangeable in a navara box with any of the other box's listed here?

thats not bad 1:1 fourth is just what it should be
but compared to the other boxes 3rd is also fine
on the navara box the problem is 1st gear is as good
as a T50 toyota box the other gears are fine or very
close to the other 71c series boxes.

180B SSS - 3.382 - 2.013 - 1.312 - 1.000 - 0.854

Stanza ss dogleg - 3.321 - 1.902 - 1.258 - 1.000 - 0.864

Ratios for 720 / Navara are wider at 3.592, 2.057, 1.361, 1.00, .852.


link from ozdat- some one take the info and sticky in the wiki.

would be good to have all the gearbox ratios listed somewhere so you could see which ones have decent ratios

4th is long, it is 1:1

Navara boxes have a long 3rd or 4th then? In third its not an issue with a torquer but in 4th well thats another story.

so much like an R30 box with 3rd

Just watch the ratios on the navara boxes close ratio on 1 2 3 then 4 is a big step. Less notable with boosted engine then 5th.
Baz told me in na l series forget 4. Its like there's a gear missing.
