WTB navara/terrano td27 gearbox

[Trench_rat]

Manual ??

[Trench_rat]

oh yes manual sorry my bad

[wax]

d22 navara qd32 gearbox
just buy one of those. I actually have one here but shipping to you would be crazy priced. But if your interested then I will look into it

[Trench_rat]

whats the advantage of going with that gearbox? and what are they worth? were are you located im in palmerston north

[wax]

They are the bigger gearbox
Nissan has a few gearboxes

the one you have is the small gearbox
the d22 has the bigger series box that comes in the gtr.
then there is the td42 gearbox.
Im on the gold coast of australia

[Trench_rat]

ok i see , oh bugger that would be a bit extravagant

Sorry to drag up an old thread, Just wanting to know more about fitting the TD42 gearbox into a WD21 Terrano with a TD27t engine.
Will it be a straight swap??
Thought i read somewhere that you need to swap bellhousings to a V6 D21 can anyone confirm??
Is it going to be too big and heavy for the little TD27t??
Wanting to know as i am thinking of running this gearbox and transfer case with a SAS front end and GQ Patrol Diffs. If this all works (as it does in my head) i should be able to do a SAS without having to flip the diff to get the drop on the right side.

Thanks in Advance

No a TD42 box does not fit a TD27. A member here passengerpete put one in his but he made a custom bellhousing and with a 2 inch body lift he still had to cut the floor.
The Td42 box is a FS5R50a
A QD32, late Mistral or manual R50 terrano box is a FS5R30a box and so is a RB30 or RD28 powered safari/patrol. If you can find one of each of these you can swap the transfer case to get the front output on the drivers side and bolt onto a TD27.
Standard TD box is a FS5W71c and they suck.
V6 terranos also have an FS5R30a but the bellhousing is all wrong.

OK Cool Thanks, Will scratch the TD42 idea.
I have the QD32 gearbox in mine now (As you said the standard TD box Sucks ass)
So if i am reading right, i can just get a transfer case from a RB30 or RD28 Patrol to get the driver side drop?? Will they bolt staright up to the QD32 gearbox or will i have to modify??

[ChurchurDan]

If you get the FS5r30a box from an rd or rb powered patrol it should work. A few months ago there was one on trademe that had been done be he wanted good money for it.

[lax2wlg]

Iirc the R30 from the Patrol has taller gear ratios which would suck balls.

Would need to mod the oil pan if going down the opposite side drop SAS route.

I dont know for sure but knowing Nissan, I reckon a TX12 transfer from an RD28/RB30 patrol would bolt straight onto an R30a gearbox from a Td27 2nd gen terrano /QD32 Navara.

Dont quote me but all signs point to yes as its the same gearbox

[bochoda]

How do you guys know all these codes?? its like your talking another language im yet to learn lol,

How do i know what code my box would be?? It came out of a QD32 Navara, not sure what year it was though.

Would modifying the oil pan be better/Easier than flipping an axle??

TX12 Transfer are they standard in all RD28/RB30 patrols?? if i can get my hands on one cheap enough i will see if it bolts up.

Is there anyway you can move this to its own topic, or is it OK that I've high jacked this thread.

Give us the details on the build plate under the bonnet and one of us could probably figure exactly what components from what models ya need to make it work.

Nissan is one company that is very good at utilizing components across a range of models aswell as supplying complete vehicles for other brands for that matter, you can even find there drive line components in Subaru's, Holden, Suzuki, Ford, Mazda, Mitsubisi, renult and as far back as WW2 with contract's to supply parts for Austin.
When it comes to there bigger TD42 engine there UD division of heavy vehicles were even sold under the swedish Vovlo Brand of trucks, untill Vovlo brought the complete division from nissan.

they also have a marine division for anyone who has a boat.

Here is the info on my build plate

Nissan Arm Terrano Diesel 1989

Q-WBYD21
WBYD21-016924
726 R

TD27 2663
FS5W71C HG46

Keep in mind that i dont have the FS5W71C gearbox in any more, i dont know what code it is but it is from a QD32 not sure on year.


Its pretty cool how Nissan is so interchangeable, Hopefully i can work out what parts i need to do a SAS as easily and cheap as possible

[Crash bandicoot]

The FS5W71C was used in the 300zx v6 twin turbo and early 4wd skylines/ patrol etc.....was superceded by the RS5R30A in 1989/90 which is what you most likley have in there now.

So you'll be needing your current TD/QD bell housing and gearbox (assuming it is the RS5R30A) and a MQ Rb30/RD28 (TX12) transfer case, which will deposit your front output on the correct side for live axle conversion.

HG46 is the diff head and will be fitted to a H223b rear housing, (4.6:1 ratio)

[bochoda]

Hey Crash, Thanks for all the info.

I ended up finding the receipt for the gearbox\transfer and it is from a 2000 model Nissan Navara QD32 3.2ltr.

So the H233b rear housing is that the same width as a patrol?? and if so could i just use a front housing\Diff from a GQ\GU and not have to change my rear diff\Axle?? and what diff centre would i use for the front??

Sorry for all the questions it will be my last on this thread, i've sort of highjacked it

[sibainmud]

Old thread so no hijack. The right people will look at this title.
All the codes are a bit confusing at first but becomes second language after a while.
The rear h233 is narrower than a h233 Y60 front. if you were going to use the front Y60 then it makes sense to use rear also.
As for the gearbox, Y60 transfer won't bolt onto D21/22 boxes without extensive adaptation. Solution is a RD28 spirit/type II box and transfer and the same diff ratios (4.625:1), good luck finding those under $1k

If you get the FS5r30a box from an rd or rb powered patrol it should work. A few months ago there was one on trademe that had been done be he wanted good money for it.

I bought one of those boxes and the reason for the big $$ was it had been fitted with YD25 ratios with ALL new bearings and syncros. My theory was to get the right box and build a truck around it

[bochoda]

The codes certainly are confusing, but hopefully i will get the hang of them

I thought they would be wider just double checking, as both have the code H233. So if i need to get RD28 gearbox would this be the on i am after ( http://www.gumtree.com.au/s-ad/greenban ... 1074950730 )

Also am i able to get just the H233 diff housing\axles and use my diff centre as they are the 4.6 ratio??? i found some front and rear diffs with the 4.625 ratio.......$1500 man those suckers arent cheap lol

[Crash bandicoot]

The diff heads can be used. Which is where it counts. But you want to use the axle housing and axles to suit your truck. But if you do live axle front, might aswell go patrol rear aswell and just run 0.0 offset rims and gaurd flares

[bochoda]

Could i buy something like this (see link) and change diff centres around, the ones here are 3.9:1 where as mine are 4.6:1, Or will i have to get 4.625 housings??

Happy to run Both diffs even though they are wider, i can work with offset wheels and guard flares
