Default Project 1996 SWB Pajero 3500 V6

Hey guys

Literally just bought this last week and there is a few mods I want to do.
Firstly Iíll be doing preventative maintenance cam belt and water pump, and other recommendations to do?

- Headers/extractors
Iíve seen these which are available, wildcat headers.
https://www.performanceexhaust.com.a...LDC/WILD247A-P

- Decating the V6 which is easily done.
- Fitting a free flowing muffler. (Recommendations)
- Snorkel and/or an air intake just a kn panel will that suffice?
- piggyback ecu tune
https://chiptorque.com.au/product/xede-processor/

From an aesthetic perspective could someone point me in the right direction for:
- Lift kit
- Suspension
- Size tyre
- Bull bars and front lighting
- Bonnet has struts

Thanks in advance guys

I genuinely dont think that the piggyback is going to net you $1000 worth of performance/economy/anystyle of gain the tunes in the later ones are as aggressive as any rally art or similar for the NA magna's and I pick that yours is not a lot different. also there is not that much gain to be had in a NA without doing supporting mods. The idea of a snorkel and exhaust is good and will gain you more than the ecu upgrade for about the same price.

other than that you list is a good start to have a fun swb . remember you are lookinga at a near on 200hp engine to start with

Full service unless you know do timing belt and water pump, do a compression test while you have access to the plugs, do plugs and leads. Replace all fuilds and I mean all. Then if you have some money left time to start on the other stuff.

While you are doing the timing belt, replace belt tensioner and the water pump with a full unit, not the cheaper half pumps you can buy on the internet, replace the camshaft oil seals and the front main oil seal. Replace the fan belts while you have them off.

As others as noted do the plugs and plug leads unless you know the service history. This will require replacement of the rocker cover seals and the seals around the plugs. Both go hard with age and leak. If you elect to do that I would pull the injectors and get them cleaned. Replace the injector seals that go hard/leak.

The rear camshaft oil seals also have a tendency to leak. Again go hard with age.

Full set of coolant hoses.

All of the above can be done with the engine in situ. However, you will have less scraped knuckles if you pull the engine. If you do that replace the clutch if necessary and rear main seal.

Then you should have a reliable engine.

Anything that is rubber and hasnít been replaced is prone to failure. What I have summarised is everything I have replaced on the last 2 years on an NL engine with only 140,000kms.

After that add the go faster and cosmetic bits. You may get better value from a front locker than a lift and larger tyres on a SWB.

The front can be lifted by tightening up the torsion bars, but if you more than 2Ē expect short service life from the CVs.

If you start doing lifts, changing shocks etc I would be carefully checking and replacing bushes, ball joints, tie rod ends etc as necessary, and particularly where you are pulling apart anyway.

My current project is replacing the boots on the gearshift and transfer shift. More rubber stuff that has failed with age resulting in oil leaks.... Where oil leaks dirt and water gets on to destroy the engine, gearbox, engine etc.

Welcome Benji.

I too, am in NZ with a 3.5 shorty. Iíd suggest driving it before you plan on to many engine upgrades. Spend your money on oils, and change the lot. Donít bother with a K & N, just put a normal paper filter in, they filter the best.

See if you can find an old set of Nissan GQ swb springs, they will give your Paj a nice lift for a nice price.

Try 4wdbits.co.nz for parts. Also Ironman etc.

Thanks everyone for your replies and advice.

From this I have made a list of preventative maintenance to do before I modify some what.

- Timing belt & water pump full unit.
- Compression test
- Plugs & leads
- Replace fluids
- Belt Tensioner
- Camshaft oil seals
- Front main oil seal
- Fan belts
- Rocker cover seals
- Seals around plugs
- Check injectors and seals
- Coolant hoses
- Check bushes/ball joints/tie rod ends
- Check all original rubber

Thats what is being done as we speak and I dropped the car off today.
I am also getting a custom exhaust into a free flow muffler and 3" tip done at the same time.

Do you have any recommendations on which headers to go for or would you go for those wildcat ones still available?
Which lift kits do you recommend?
Im also wanting 33" A/T tyres what's the widest I can fit without any modifications? its being used on the road and beach because i'll occasionally be towing.
I have changed my mind regarding to the piggyback tune, bag for buck a tuner here pretty much said the same as you guys minimal power gains 4-6KW max.
With regards to the bull bars there isn't big selection for the 96' SWB Paj. Tempted to just go for a nudge bar instead.

What headlight bulbs are in the paj because ill change them from being that yellow tint to a brighter white!

Another other recommendations would be much appreciated

After all your advice I did all the preventative maintenance mentioned.
Plus I’ll be doing the bushes too!

So far I’ve done a 2” lift kit with 33” fallen ATs
Muffler has been done but I plan to do headers too.
Having slight issue I’m not sure whether I’m the genie oval port or the normal wildcat headers..?
Been looking at tunes and a piggyback pnp is the easiest! AEM do a FIC6 where it can be tuned some what!

several of my mates here in WA have reported that they have not noticed any gain from headers on their own - some have fitted to stock exhaust others have fitted to and already modded exhaust - the only who have noticed were those who have fitted a whole system at once and that seems to be little different to those who have fitted a cat back system.

That said Mitsi v6 exhaust manifolds are reknown for cracking and causing bad O2 sensor readings.... extractors are useful just for this and I have had a few reportys that they do improve fuel economy due to this

Thanks for that mate.
Currently I am not sure which ones I need, oval port or regular.
What would you define as a whole system?
Currently running a custom 2.5” from the cat back to a muffler.
Would you suggest removing the cat? With a sports cat or a resonator..?
Appreciate your thoughts!
