Performance 2.6 Pajero

Has Anyone Played Around With Webbers And Exhaust's On Mid 80's 2.6 Pajero's ?



I Have Been Told The Webber Of Carbi Xf Falcons Are Good With A Free Flowing Exhaust Makes A Huge Difference/?

The best info available on the Mitsu 2.6 is 4x4Wire

Those guys can tell you all you need to know.

Hi Mate,

I had one years ago when I was working for Mitsubishi and we machined out the standard carburettor (the aluminium bodied one is better for this), fitted a twin pipe exhaust manifold from a 2.6L Sigma and 2 1/4 inch exhaust plus what we then called a Ralliart Safari cam. This was a similar setup to what the very first Ralliart Pajero's ran in the original Australian Safaris. With thses mods the 2.6L goes pretty well. It is possible to get them to put out as much and more low down torque than the early V6 did.

Mal from Crockenberg Motors in Perth would know more exact details if he's still around.

Hope this helps.

picking up a falcon carby cheap shouldn't be too much of an issue...getting rid of the free falcon that came with it might be though :)

from what i understand...there's plenty of gain to be had from these motors with an aftermarket camshaft....brother-in-law was talking about doing that to his pajero, but my sister wasn't so keen....

I was looking at going down the turbo path with the triton but I found it cheaper to go for the commy 3.8 v6. I'm half way there.

Can't remember the place (its in Perth) but for around $1400 the have cam, carby, exhaust packages. Nice big cam, modified carby. Can get an exhaust done locally though which cuts down freight expenses.

yeah the 2.6 is a good old motor.

4wdm ran an article a while back on how to get more grunt outta petrol engines, it pretty much mentioned what you blokes have said

exhaust-cam-bit more compression(a bit machined off the head)-bigger carby



i just rebuilt my 2.6-took a bit off the head, got rid of the balance shafts(chains were bouncing around)and got extractors(hitech headers) and 2" exhasuht the whole way through, now im looking for a cam that will help with down low power(not crazy revving stuff like the crow cams' one).


there is also also a thread a while back which talks in more detail about the types of carbies people have used- i think it was called 2.6 performance webbers or something simmilar


and for those wanting even more grunt :D :D you can even work on an efi system from a magna or something simillar- there is a thread on outerlimits4x4.com which goes into great detail with this and has pics

EFI I say yes.
Shaving the head I say no.

As good as these motors can be the alloy heads are rather susceptable to warping...easy. I know, I done it. Apart from that if you can get a good strong aftermarket head it is pretty well bulletproof.

the 2.6 is a tough motor, i had one in a 76 galant that was good for 12secs on th quarter. it had a blue printed and balanced motor magna head that was flowed and match ported custom split pulse turbo manifold and a garret T04 running 15 psi. if i was to do a 4x4 motor i would remove the balance shaft flow the head , match port it and put larger injectors with after market computer and a good free flowing exhaust , no turbo though

I used to do this for a living.
Mate you're spot on with the XE/F Ford carby they work a treat and run well
off road even on steep hills.

I found it better to run a full flow air cleaner on them with big bore extractors
and 2.25 or 2.5 inch exhaust then advance the timing a tad.

Just done this to the young blokes 2.6 Triton 4x2 work ute and it goes VERY well and have managed to get 27.3 mpg out of it.
Could only get approx 22 mpg before !

Hope this helps bms

PS: The carby will need to be rejetted .
