Outer Limits 4x4 Board

i have a 84 pajero with dead 2.6 is it possable to fit a TR magna 2.6 motor and what mods need to be done, has anyone done this conversion i know sigma motors fit but are getting hard to come by in WA now, any help would be appreciated

Are you including the Magna EFI in your transplant?

Magna & Sigma have different inlet manifold stud patterns, and I'm not sure which pattern you would have on your Paj. Other than that, I think you'll have to swap sumps, oil pickups and do some work with the alternator drive - from memory, the Magna drives from the rear of the camshaft. Typical solution is to cut the drive off the camshaft and seal the gap - seems to work OK.

thanks for the reply i would like to do the efi i have seen how the its done on the internet , not to sure on the wireing that me be to big for me, also the magna motor bolts up to the pag gearbox okay do i need a auto or manual doner moter or are they all the same.
Cheers

would the magna 2.6 even have enough power, i just no the 2.6 is such a lemon of an engine.

You would have to use the head from the Pajero because the Magna head has the water pump driven from a pulley at the clutch end of the head. I cannot remember where the water pump is for the Pajero, but I am sure that it isn't there. Using the Pajero head will mean using a carburettor, thereby avoiding the need for an injection computer etc.

I have a spare 2.6 from a '92 Triton if your interested. Only thing is I'm 3000k away

thank all, i have a magna motor at friends thats why i looked at doing it as a freebie its a good start the whole pag isn't worth that much so i hesitant to spend to much as i would rather update to a later model if it came to that, i still like the old girl but you need to keep realistic.
Cheers

Please explain to us what makes the 2.6 such a lemon of an engine.

And yes, the magna 2.6 produces more power and torque than the Pajero 2.6, so that's not an issue.

my parents owed one and had nothing but dramas kept cracking heads after getting rebuild just was a piece of crap. maybe we got the only lemon

m8 i used to race a scorpion at speedway here for years, always used a 2.6 wide block found in the magna/pajero/canter and gj sigma on, all engines are interchangeable with a lil work, magna was the only one to use injection tho, id be using your pajero head to keep it easier and leave the carb on there, as for 2.6's being a lemon, i have never had a problem with cracking heads, only drama i have had is 1 or 2 blown head gaskets due to running 12.5:1 compression and getting it hot from racing and a few bent rods here and there, and its pretty easy to get 150hp atw out of them if u kno what u r doin, my 2cents, i hope this ramble helps lol

Mitsubishi 2.6 engines in early Magnas did have problems. We had the first model Magna (a TM) and it had a welsh plug problem and also eventually cracked the head. The head problem occurred much later and was not related to the welsh plug (which was due to thin walls on the cast iron block). CJ engines in Mitcham Vic repaired the head for a very reasonable price and we never had a problem after that.

I think the later models were OK, although you can always get a lemon. We also had the balance chain tensioner bolt break (again modified later) but other than that, had no problems. The TP models had a hydraulic balance chain tensioner and I think they would be quite reliable. When we sold the car it had 345000 km on it and last seen it had 375000 and still going. I put standard rings in it at 235000, but only because I had the head off at the time. Regular oild changes will ensure a long engine life. Reliability is fairly well proven

Suffice to say that we bought 2 mitubishis to replace the one we had before and to date have had similar reliability from them, albeit they are totally different vehicles to the TM Magna.

thanks all i will proceeded and see how i go hopefully with out to many glitches, it will be good to get the old girl off road again , cheers Gatzk

Putting the efi into a pajero I think is a good idea, was going to do it myself recently but a cheap reco engine came up so I went with that. I did a bit of research on it and came across a fella who has documented his conversion in a different forum so if your gona go that way it would be well worth a read.

Hope this help.

hi thanks heaps i read the thread and should be able to tackle it pretty confidantly, starting in a couple of weeks i will get back to you guys if i run in to any trouble thanks for all your help
Cheers Gatzk

Slightly off topic but....
I see mention of a different form of timing chain tensioner on the Magna. I have a '92 2.6 Paj and tried to tighen the chain as per Haynes manual, however it looks totally different inside (no chain guide or "special bolt B"). Instead there's just a pozidrive screw head.

It's pretty hard to see so I took a pic (below...)

Does anyone know what I need to do (if anything) to set the chain tension?

cheers

My recollection of TP Magnas is that they had a hydraulic tensioner for the balance chain, so this is probably it. It certainly looks like a hydraulic or spring type tensioner - nothing like the earlier TM Magna tensioner adjustment.
