A Pajero GDI 6G74 that backfires but won't start could be experiencing issues related to fuel delivery, ignition timing, or air-fuel mixture. Common causes include a faulty fuel pump, clogged fuel filter, or malfunctioning injectors that disrupt proper fuel flow. Additionally, a problem with the ignition system, such as worn spark plugs or a faulty ignition coil, could lead to incorrect timing and backfiring. Checking these components systematically can help identify the root cause of the issue.
When looking at engine from front of vehicle it is first cylinder on left bank, cheers.

Yes. It's basically a straightforward swap for a non-turbo. Would suggest an upgraded (Walbro 255) fuel pump. http://www.3si.org/forum/f35/my-6g74-3-5l-swap-webpage-240131/
The Mitsubishi 6G74 engine in the Montero has a firing order of 1-4-2-5-3-6. This V6 engine features a 60-degree angle between its banks and is known for its smooth operation and reliability. Proper understanding of the firing order is crucial for maintenance and performance tuning.
The only engines that will fit in this car without significant modification to the car are the stock engine (6g72) or the Mitsubishi 3.5L 6g74.
In the Mitsubishi 6G74 engine, the oil holes in the connecting rods are typically positioned to align with the oil passages in the engine block. This design allows for proper lubrication of the rod bearings during operation. The oil is directed through these passages, ensuring that the connecting rods receive adequate oil flow to reduce friction and wear. Proper alignment is crucial for optimal engine performance and longevity.
It is possible to swap the engines, and the V6 gives a noticeable improvement over power and acceleration. Just make sure the transmission can handle the V6 or swap the transmission as necessary.
If you are looking at the engine bay from the front of the vehicle, it will be on the right-hand side, under the timing belt covers (must be removed), on the bottom side of the engine (must remove front driver tire to get at it with ease). It looks like a 3 point "ninja star". Included link to diagram: {http://www.3si.org/forum/f1/6g72-6g74-engine-diagram-measurements-440490/} (I own a 95 3kgt)
The 6g72 (3.0L v6) can be found in 3rd gen eclipse, Dodge mini vans, 3000gt's among a few other cars. You can also use any 6g block like a 6g74 from a galant or so on... but the one to go with would be your 3000gt engine from 94+ due to the block revisions and aftermarket support.. The answer if it can fit is yes... Do you want to? probably not.. Reasons being this. Engine mounts will have to be custom fit to your sub frame and side mounts for the engine.. you will have to source a 5Speed awd from a non turbo jdm GTO because the gear box is the same as the dsm, and it uses the same drive line after the bell housing basically.. easiest wire up will be stand alone OEM ecu and harness conversion.. Not easy unless you get a donar 3000gt for both, engine, and electrical due to the 3000gt's having like 4 different wire harness set ups and they came in 2 sections and several ecu's.... on top of all that.... only the non turbo block fits into the car easily.. you can do a supercharged turbo block or a remote turbo... But dont plan on fitting a turbo engine into a talon oh and it will be alot easier to do it to a 1g dsm vs a 2g... ALSO keep in mind that you will be doing the usual conversion stuff like power steering, ac, oil cooler lines, fuel lines, coolant lines.. the ups are the 6g72 dohc is built to be mod'd just like a 4g63 by design.. and the 94+ blocks use a nice main cap girdle to add durability to your bottom end... but really.... With all that customizing... id just as soon custom adapt a twin scroll 16g off an evo 8...
