Need help with Engine Mitsubishi L300 4x4

Sigma also ran a 2.6 as well as the Mazda 2600 tray top utes.

Hello thank you so so much for your reply! Yes the bearings has being the issue and this week they were going to check what it needs to be done for it,if it needed a crankshaft! But I didnt see them really enthusiastic of doing the job so thats why I wanna ask because if there is a chance I wanna give it a try and maybe take it somewhere else!

Do you know if a lot of things around needed to be changed?

I don't know someone who has done an engine swap on here would have an idea what's involved. Maybe Mitsubishi have a suitable turbo diesel.

In the late 80's a mate ofmine had the 1.8Ltr 1983 model it got 13 - 14mpg my 4.2Ltr FJ40 got 16 - 17mpg don't know how a small 4 cylinder could possible use that much on road but it did. Also as most know not that good off road and 4wd disengaged when you select reverse he didn't keep it long but they were pretty fancy inside would have made a good off road camper with limitations though even after a few mods and a better motor.

RMD correct ..all the Sigma 2 L and 2.6 in all have the balance shafts and chains.. we used to do many rebuilds on these engines back in the day and as you mentioned as a must all chains and guides would be replaced ,who would forget the Sigma chain rattles lol.

Looks like a happy camper, and to his credit restored it well, just hard to get spares for.

Interesting.
I could easily be wrong as there were a lot of misconceptions in the Aussie motor industry back then but I do know the first sigma models were released with an 1850 and 2000 options. I learned to drive in the 2 litre version, later with the as claimed by Mitsubishi, an Australian engineered 2600.
Father owned a 2.6 wagon as well.
Never got to drive an 1850 but the 2 larger versions were crap, the heavy ballance shafts made revving a very slow process.
Not sure what engine they were running in the Australian release of the gallant but it was a lot more fun to drive, made the sigma feel like a slug. NZ had both versions of the gallant, one being a sigma with gallant badges.

Qld the balance shafts were meant to stop vibration but were easily removed modification but I couldn't really say that there was a noticeable difference either way . the biggest problem was when people didn't tighten up the nut properly on the balance shaft in the oil pump and it would unscrew and come out through the front of the timing cover. The imported 2.6 had a far better cylinder head with bigger valves and ports making it a lot better motor when modifying it . Like the engines that David"Dinnta" Officer would build ..The gallants were a 1600 engine and like most small engines would rev better .The later gallants had the sirius belt drive motor .

Another thing all the earlier ones suffered from was one of the chain guide bolts stepped down from an 8mm shaft to an M6 (i think, could have been 10 to 8) thread and would snap off, we were lucky ours didnt damage the timing cover but most did. Dont think they changed that till the magna engine.
Glad those days are long gone.

Remember the starter motor issues?
All of the 2000s suffered from it, we did everything to overcome it, 11 plate batteries and 2B&S cables direct to the starter.
Bosch released a bulliten that the starters were designed to mistubishis requested specs but were too small for the 2000, the specs given to Bosch were for the 1850.
I built a slightly more powerful but longer starter for ours but required the modification of an engine mount to fit it in, it worked a bit better but not viable for customers cars. Wasnt till the first generation of reduction denso and mitsubishis own M2T series starters started showing up on lo milage jap imports the problem was solved and then Bosch come out with their own planetry reduced starter for the magnas which come standard with its own faults.

Again, glad those days are behind us.

The 2.6 Motor was also used in the Pajero, in fact it was the standard motor in the Pajero for a number of years.

Macca.
