Hi knowledgeable Patrol people!
I’m looking to upgrade my FS5R30a trans on my 1998 RD28 to a FS5R50b, can someone confirm if the new trans will work fine with my existing transfer?
And is this code the upgraded later type 50b; 32010VD200?

Sorry mate, i dont have a answer for you. have to called Patrolapart? they might know straight up. Otherwise if anyone has the answer chime in please.
I was told early on that the transfer cases are the same (Can't confirm that. As MR suggested, Patrolapart should be able to help), but you will need an adapter plate or different bell housing between the RD28 and the heavier transmission. I was also informed by @nissannewby that the heavier transmission will sap a lot of power from a stock RB or RD engine
Hi all, thanks, my findings seem to be theat the transfers and fitment are the same, but no concrete source to confirm it.
@mudnut thats an interesting point you make, this vehicle only does mild off road at best, mostly road touring, so the decreased weight and fuel saving of the 30a box may be better than the strength benefit of the 50b?
Is the 30a safe with 400lbft/540Nm on 32" tyres?
So you've had the engine modified? I've read that they only give 170 to 180 ftlb stock. It should go quite well with the 50a at 400ftlb.
Cheated soz... OM606
Well, that changes the scenario completely, that is a f*cking beast of an engine.
I would like to know if the 30a is comfortable with 400lb and 32”s as I would really appreciate the fuel saving if it can, bearing in mind the OM606 doesn’t make its torque like the V8 diesels, torque is comes in a lot later like a petrol.
I know that a mob in Bayswater do upgrades to the 30a. I rang them and apparently they try to strengthen areas where the boxes constantly wear out. I would definitely go with the 50B. The box itself has a stronger raised grid pattern cast into it for extra strength.
There was a fault with a run of the 50, where Nissan didn't machine deep enough splines for 4th or 5th (can't remember which gear) and they failed. Hopefully a knowledgeable member of the forum can tell you which series had that problem, And how it was fixed.
Do recall watching a Legend from the UK on Youtubey only a few weeks ago that had your wicked Merc diesel too in his Y61 wagon over there [emoji123][emoji123]
Cannot find the video again but seem to remember he mentioned exact engine power numbers versus the big box as his choice, worth trying to find that video I believe DG370 Mate [emoji106][emoji106]

Appreciate the info guys, will see if i can find that YT vid, i does seem that if common sense are to prevail i should just stick a 50b in for peace of mind.
For those interested, the transfer boxes are completely compatible - confirmed with a specialist here in the UK.
Also for reference the 30a and 50b both share the same input shaft too.
For what it’s worth too DG370 Mate, I stopped into a Melbourne (Dobinsons Springs) outlet only last week or two to pickup and whilst waiting learnt a shipload off the young Bloke Legend on the counter. Him and his knowledgeable genuinely overachieving friends were very experienced in converting cheaper Aussie GQ (Y60) 2.8L trucks to extremely higher powered Ford Barra/Chev type motors IIRC?
Young Legend straight up said their weaker boxes cannot handle their Shenanigan’s and his Mrs had laid down the laws of no more!!

Hi Guys n gals. Been a while and I trust you’ve all kept well.
DieselPumpUK on YT is a compendium of information on the OM606 into various cars. He bought a GU to match to a big turbo OM606 because of the strength of its drivetrain & the results seem too good to be true. Fully mechanical MASSIVE fuel pump & custom intake manifold and pulls 6000rpm’s.
The boxes in the RD28 are also used in the Skyline and the other Nissan sportscar - 300Z - perhaps they are up to the HP and torque? I know its a huge difference in size to the TD42 box. The transfers are the same, just the housings change - I have the same transfer in my V8 from the RD28 upgrade.
There are upgrades available from places like 360 Gearboxes & Diffs PTY LTD in Bayswater Victoria. I had a chat with them about it a few years ago. They listed a quite a few things they do to keep the boxes together under high loads. It comes with a fairly high bill too. Personally, I found that the bearings in the gear cluster tend to wear out when towing, I tend to nurse the unit.Quote:
