RB gearbox/Navara Gearbox

[BASHERnissan]

Hi everyone

 

I've seen/ heard a few things about the Nissan Navara Gearbox being the same or similar to the RB25DET and rb30et gearbox. Is this true and is it worth the effort trying to bolt one up ?!?! Sounds like a cool trick haha found a 2wd 6spd manual for 1k on trademe... 

 

Anyone know any solid info about this ? Cheers

RB30ET = VL Turbo gearbox. Yeah but single synchro per gear IIRC

I don't know about Navara

It's not the same or similar if it's a 6 speed

What about the 5 speed RWD box ??

Anyone know anyone who done this

There is a 5 speed but by the time you found one and then swapped the font half of the casing or made an adapter it would've been easier just to get a 25 box

The d22 navara have similar internals. Unfortunately the input shaft is longer so you would have to space it back by use of an adaptar plate which also means modifying driveshaft, clutch line and shifter. 

You can't machine the input shaft to suit as cutting it down resplining isn't possible with the smaller od, as shaft tapers down past the spline.

Yeah the qd32 box has a longer input, it's not that easy to come by & usually not cheap
