V6 Navara Gearbox

[DJRIFT]

hi all

i was talking to a bit of a nissan guru the other day about what gearbox to run in my R32 when i do the conversion. he said that rb20 turbo and rb30 NA gearboxes are exactly the same apart from the ribbing on the box housings. so they are week. he then said that i should get a R33 box as they are the strongest. he said that the r33, rb30 turbo box and the navara V6 manual gear boxes are exactly the same.

has anyone ever tryed to fit a manual gearbox out of a navara? or have they ever seen one and been able to say that they are the same box?

i know this is a big ask but any help would be grately apreciated

even if they were the same gearbox you still have to get rid of the transfer case. that alone would cost more than a R33 GTSt gearbox.

mmm... i think your guru is having a bad day

I believe it's the VG30E (ie SOHC) in the Navara, and yes the 2WD version uses a gearbox which is similar in size and strength to the R33/VL turbo types BUT the bell-housing bolt pattern is very different and it won't bolt up to an RB block without an adaptor plate (or changing the bellhousing - if possible).

thanks for the HELPFULL posts.

the 2WD version behind the VG30E is the one i ment sorry i didnt expand my question.

so same box on the inside but wont bolt up to an RB without some work

would the gears drop into a VL turbo or R33 gearbox casing?

the reason i am asking is because a mate of mine needs a V6 navara engine and i need a box so we are maybe going to get the engine and box together.

thanks

The gearbox really wont be a cost viable option i dont think... if you get it for $100, then maybe. But even then...

By the time you dick around as SteveL said, with either the bellhousing... i know around the $1500 mark as a mate had a R33-t box modified to suit a 240z... or adapter plate, less $$$ but still a mission

The R33 box could be had for less of an overall cost, and also less time spent working it all out.

As for the internals interchangeable... not sure

does anyone know what ratios the navara box runs?? i figure they would be different to skyline since its an NA V6 3L work truck, not a straight6 2.5L turbo sports car.

Pretty similar probably, the diff is usually where utilities get their short gearing from.

We took the internals of a Navara box and used them in a VL Turbo gearbox once. Can't find the MX7 anywhere, ridiculously rare. For this reason, converting to a VL turbo box is a pretty silly idea.
