hey guys

just wondering what type of divorced transfer cases are out there. i know of mq but i would really like something that can be geared up.

thanks

mike

There are zuk cases then new process 205 its an american case way strong .You can also get an adaptor to bolt onto the front of a hilux case to make it divorced from OTT industries in the states

The Atlas II is available in a divorced version.

Lada niva, NP 200 truck case, and as above.

Steve

how would a zook transfer go behind a nissan turbo 6 and an auto in an mq???

i think it may break.

np 205 what are they out of and a rough price? can u put gears in them??

np200 what vehicles are these out of??

an atlas is out of my price range

Lada Niva, has reduction in 'high' as well as in low to compensate for those big tyres... not as strong as some but stronger than a zuk one i think.

Probably wouldn't set you back more than a hundred bucks used.

can you get gears for them??

what sort of reduction do they offer???

I don't know if you can get gears for them or not - maybe OS you can - but they come stock with 1.2:1 high, and 2.135:1 low. The low is not that good I guess.

He's looking for a case to go into a turbo'd 6cyl petrol MQ patrol.

Not sure if the Lada case would be strong enough.

The NP 205 was used in various fullsize pickups in the 70's and 80's. I think the divorced ones were used in australian spec "highboy" f250s, 1978-1979. the divorced versions are the hardest to find, and are the weakest as they have a smaller input shaft or something.

PS the F250 versions are LHS drop (front diff centre on the left)
I am not sure there was a RHS drop divorced version.

Ratios are 1.1 high, 1.96:1 low from memory
They weigh about 90kg.... cast iron case.

reduction gears - the lowmax kit is available in the US @ 3.5 :1, but that's basically a whole new case. It is quite expensive. Most US guys double them up, but this requires an NP203 low range box and does not work divorced.

I don't think a zuk or lada case would be suitable.

Steve.

Wasn't the nissan 720 divorced as well?
Peter.

mq l28 wagons had a devorced version of the stock transfer.
yes a 720 transfer is also devorced

There are a couple of people who have converted the Land Rover LT230 to run divorced. Stock low ratio is 3.32:1 - which is already lower than most. Maxidrive make 2 lower sets - 4.3:1 and 4.6:1 (?).

At least 4 different high ratios are available stock as well.

I think it was a chevy or dodge Np205 that was a divorced Right hand drop transfer

datto 720 are divorced and i think have the same gears in them as a MQ Patrol.

Some people in the states are running 200kw through them with out probs

Im either going divorced hilux with the adaptor from the states or spending big and going for an Atlas with 5 to 1 ratios

By the time you add up:

Cost of donor transfer case
Cost of gears
Cost of divorced adaptor
Cost of rebuild kit
Cost of disconnect

You might as well just buy an atlas.

Given that there's a Marks kit for making two GQ transfers into dual transfers, it seems like a GQ transfer should be amenable to being converted to divorced operation as well.

Bolt a G60 three speed with G60 transfer case onto the back of your automatic, that'll give you some interesting gearing! A lowest gear of 6.6:1

Might be a little bit bulky though.

If I go Hilux it will be one adpator to make the case divorced then one set of low range gears 4.7 and bying a hilux case so not that expensive.But would realy like an atlas with either 5 to 1 or 6 to1 gears almost unbrakable

if you want run a turbo 6 in the mq i guess its going to go fast with a lots of rpm and a remote transfer may suffer some bad vibrations in this set up if you are using a nissan rb25/26/30det why not use the gq rb30 5sp geabox/transfer around $500 complete bolt up to your engine turbo'd if you insist on auto id use a jatco from the vl rb30 commodore easier to work on, much cheaper to buy, plenty strong for thrashing.
then again i might be way off you may have a nissan vg20/30det in which case you could use navara manual or auto with transfer as one, as it all bolts up too
then again it could ba a turbo'd L20b?????

or you could tell us what you are planning and we might give you an alternitive or pat you on your back

I have seen a green land rover hybrid that adapted a jeep under drive onto his pto out-put on the transfer , i think suzuki made a pto unit to go onto the remote transfer case, you could look into mounting an under drive unit onto the back of your nissan remote transfer ?

my 2 cents

Tim

i have a under drive for a trimatic for sale if that is of any use trimatic included

oh it has a sierra wt or hilux flange on the rear for a remote transfer i should of added that

alrite

i currently have an mq l28 turbo. engine makes 135kw at the wheels atm should make a bit more soon. its a manual but i am looking at going for an auto. i would like to use a different transfer case so hopefully i can get something i can get more reduction in as i am using big tyres. the mq transfer is not low enough for what i am after and you cannot put gears in it. the truck is a shorty to but i will be going MWB in the not to distant future but i still dont think it will be enough room for dual cases.


that is why i was looking at what other divorced cases were out there. something that can handle the power but also can get gears for or has good standard reduction ratios.

Why not just run a T700 into a GQ transfer with gears?

IMHO you will have plenty of length for duals...

An auto+tailshaft housing+jackshaft+ transfer is generally as long as duals. It is certainly longer than a mated transfer like a GQ or Hilux.

As per the earlier post, with high power you will have more problems with vibration and more potential for failure with two extra unis.

Steve.

on this subject.
i saw a 150mm wide 20mm thick rag joint used between the flanges of a ca18de and nissan box a sierra transfer case hole thing less than 100mm long never seen anything like it very simple and neat i dont know how much power it would handle but a standed ca18 would be some where around 140 hp and its being flogged for 2 years on road so far.
I know the guy who made it I might try one in my 230hp ca18det powerd sierra as my gearbox transfer shaft is to long for my liking, mine is basicly a double cardenol joint at 220mm and it has vibration around 5000 rpm it goes to 8000rpm so yes its a issue

Dont quote me on it but i think the patrol GQ rd2.8t gearbox bolts up to the L28 engine Has the good transfer that is fixed hanging off it and has the ability to add lower gears. Worth looking into anyway

would be awesome if that gq box would fit.

i would go that then.

i just dont know of anything else that has the same bellhousing or something that could even be adapted to the l28.

dont know if this helps but when i did have a RD2.8t in my GQ i was told by someone who did know his nissans/datsuns damn well that the 2.8t was based off a L2.8 and had the same bolt up for a gearbox also there are a few skyline boxes that would fit up as well. I used a skyline performance clutch in my GQ as so i could slip it a bit off the line in order to get the bag of crap to take off from a standstill a bit quicker.
Might be a thought to try get ahold of one at a wreckers to try fit to the l28 if they have both there If it fits then buy it. I would go for the GQ one over the GU one as i have herd of GU 2.8 boxs throwing 5th gear. But then it maywell have been driven wrong aswell.
The 2.8t and the 4.2t use the same transfer case so no worries with bolting one up to the 2.8 box. They do use diffrent shifters for the low range though( or was it the selecter bracket mmm)
Hope this helps
