Gen4 pajero LS1 V8 conversion

[smccask]

If anyone has an NS transfer out of a car, it'd be super useful if i can get some good pics of it! I'd need some side-on views of where it connects to the gbox and also some front-on shots. Also would be good to get a count of number of teeth in spline plus major and minor diameter of the shaft input.

I've ordered a CAN adaptor so i can start to reverse engineer the mitsi comms. Hopefully i can restore the ASC and TC and also the factory dash functions

Will definitely be watching this with great interest Simon. Was hoping to see the NS transfer case used and keeping the superselect system but either way can't wait to see how it all fits.
Whats your opinions on just doing a bell housing swap onto the paj transmission? I've seen it done with BMW v8s and straight 6's in Europe this way? Or would an LS kill it too quick? Even if you had to spend money getting the tranny rebuilt HD to cope, it might be worth it to keep all the shifters and mounts and shafts stock. Then either trick stock oem driveline ecu with tach signal and tps from LS or use an aftermarket transmission controller.

Given the amount of gen 4 transfer cases that get destroyed with a dirty diesel I can’t imagine one lasting well with a LS driven with any sympathy....

Looks like a fun project!

Its possible, but both cars run a PCM covering engine and gbox so i think they are inextricably linked. Using the manual paj box might be a good option instead.

What breaks on them?

Got the paj in the shed today and with help.from a couple of mates we pulled the transfer off to see what's between that and gbox...and have a general look around underneath. Crazy luck... the NS transfer has the same input spline as the NH auto transfer! So I'll be able to use the NS transfer and mate up the LS1 and 4L60e. Nice! Also generally lots of room under there compared to NH..no chassis rails helps!

Paj going in tomorrow for new airbags and indicator controls recalls

Simon, you may be better off sticking with the NH transfer case, there are some examples on this forum of Gen 4 transfer cases failing.

What are the differences between Gen 2, 3, 4 transfer cases though?

From my limited research, mainly around Gen 2.5 manual transfer cases and Gen 3 manual cases I was left with the impression the only differences were electronic activation of the transfer case in place of mechanical linkages.

I have assumed the failures in the Gen 4 transfer cases are more due to the huge increase in torque from the CRD engine compared to the older super select cases, and more spirited driving.

I will have to have another look under my NX and NJ to compare external differences. I have assumed they are identical enough that the lower low range gears available for the Gen 2 and 3 manual transfer cases will fit in the Gen 4.

[Ian Sharpe]

Not sure what the differences are but you could be right in that is is a torque problem given that the NT diesel was upgraded to 440nm. However AFAIK Simon has never had a problem either with the NH auto case that he is using behind the LS motor, so who knows?

Designed the adaptor plate last night base don the measurements we did on Sunday. I reckon it'll work out pretty sweet made from 40mm ali plate. The front half with 6 bolt pattern is from Advance Adaptors (part of 50-0430 kit) and then the rear half with the crazy bolt pattern is the part that needs to be made. It should result in the bell-housing face and transfer in the original Pajero position.

Simon, another blown Gen 4 transfer case , might be better to stick with the one you have , at least its proven!.

[smccask]

Hrmmm, damn hey!? I'm still leaning towards kerping the ns transfer... mainly for the vehicle speed sensor, no driveshaft mods, no console or electrics mods. I guess I'll store the nh one somewhere as a fallback plan.

Spoke to the engineer (Terry Southam) Jake and i used for our NH and NL conversions today. We spoke through the details and he reckons no real dramas. Won't matter that the engine predates the car over those years as they have the same emissions tech and requirements. Will need to sort out the ASC tho, which could be a challenge.

I'm sure you are up to it mate! That was good news to hear
