Hey guys! I have a W5M33 NRBE gearbox in my gsr, wondering if i can replace it with a W5M33 NRWE gearbox? i know nrbe has no lsd and nrwe has viscous lsd.. needing to replace my gearbox as synchros are gone.

Thanks!

I think the shafts are different for viscous lsd.

I think so too ^

So i will need both cv chafts to match the lsd?

rh shaft only will work with a viscous

See pic.
For the front viscous LSD you need the longer cv cup shaft that goes on the driver's side of the gearbox (Aussie RHD vehicles). The LSD CV cups are hard to find!!!
For the other side (the engine side) you can use a normal jackshaft that goes into the gearbox and bolts to the back of the engine block.
As a sanity check, make sure you do actually have a front viscous LSD. Look into the guts of your gearbox where the CV shafts go in and you should be able to see straight through it like in the pic I posted. If there is a silver pin inside blocking your view, then its not got a front LSD.
Both are GSR AWD gearbox codes so the gear ratios will be compatible. It's just the CV cup shaft that you need to sort out.

Thank you all for your help, i really appreciate that, so i will need a drivers side lsd cup shaft for the NRWE.. And if i was to get the NQBE gearbox which is the non lsd version of the NRWE, could i use the same cv cup shafts off my original gearbox?

Thanks again.

You need the long cv cup for a front viscous LSD.
Do not use the long cv cup for a non LSD gearbox.
The oem normal cv cup should only be used for an open front diff or a mechanical front LSD.

The reason why viscous LSD cups are hard to find is because guys forget to sell them with their front viscous LSD's.
They viscous LSD's are basically useless without the long cv cup to go with it. Unless you can get another aftermarket one from somewhere which is going to cost an extra $200-$400 from what I've seen.
