Quite the first post. Welcome to the forum, you've got a long road ahead of you with this build.

I would swap all of the Sport steering and suspension minus torsions (they should be too long, get 93-93 Monty torsions). The rear springs are military wrap and much better but they take a little work to make them fit the old front hanger. They will rub slightly on the bottom but you can stretch the opening with a crescent wrench or trim with a grinder, you'll see what I mean it's obvious.
 Charlie has a post here with all the bellhousing part numbers, he doesn't have many threads here so it should be an easy find. As for the crossmember I would try both and if neither work just combine them to fit.
 Personally I'd rock 4.63's but that's coming from the Montero world and L200's are significantly lighter and more aerodynamic so 4.27 gears might be better (4.22's are 2WD rears or so i recall).

 Are you buying a new crate engine?

Your build sounds very similar to my 90 Mighty Max 4x4 build except for one thing. You are going diesel where I went for bigger cubes. 3.8l MIVEC.

The rear disc axle is a fairly straightforward swap. Tying in the ebrake will take some work and customization. Not fun. Pull the cables with your axle when you do. Pulled mine 9”  from a 97 sport. Keep in mind your axle will push out another 1.5” iirc on both sides. Doesn’t look bad though. I thought about locker too but no real good options out there and they inevitability fail at some point. The factory lsd is just as good, so I installed mine with the factory 4.22 gearing.

I also picked up the V5MT1 trans out of that sport. The only real gains I found in my research is that it is a little more robust and that they improved the syncros for high speed shifts and downshifting. Perfect for my application but probably not a deal breaker fo you.

Do the 2nd gen Montero front disc swap. Big improvement.

Ditch the exhaust idea. I have a cut out on mine and I see no difference when I switch between the two. Factory exhaust is more than adequate.

Wow. Very ambitious build. Welcome!

I've had the 4d56t in both a Pajero and a Strada (l200). The paj had 488s and I ran 33x1050s. The pickup had 462s and I found for highway use, running 31x1050s was about the best way to use the powerband. I'm glad you're sticking with a manual trans. This engine is anemic to the point of unusable behind an auto and torque converter in my opinion. I think with the tire you're looking at, the 462 is a much better choice. The low down Torque of  the diesel lets you stay in fifth on the highway even for moderate hills but I fear the 422s will have you lugging far too much and downshifting more than you want to. But it depends on how you intend to use it I guess.

In terms of fuel economy, mine was happiest right around 95 or 100km/h. Over that I found economy dropped off fairly quickly. Opinions are what they are and ultimately you need to look at your usage to determine best course. You're going about it the right way and will come up with a good plan by the sounds of it.

Look forward to seeing this come together.

Mike Warme is the guy that builds diesel Mighty Maxes, owns a ton of new old stock and a ton of used parts he is a very knowledgeable guy. He built the truck for Spence (4D55Performance).
 
 Charlie is CharlieN and he goes by OldColt on the other forums.

 Have you looked into used 4M40's at all? They can be had attached to a V5MT2 5 speed already. There's one for $1500 delivered but they don't say if it's an auto or manual, one with an auto for $2000 and one for $3000 with V5MT2 on eBay.

I agree on the new Hyundai engine being the way to go, for the price and being new and complete vs old unknowns. Just thought I'd throw those out there, the main advantage there being it coming with a trans.

 I found Charlie's post but he never posted back with the 4D56 V5MT1 bellhousing, just all the V6 stuff. Here it is, maybe you can re ask him.

On the left is beauty. On the right is a KM-145.

Surrounding these is my junk pile.

Slight correction: The one on the right is part of your junk pile. Just my opinion, of course. I don't like the KM-145 for longevity.

Rxin:

Thanks, in that case, I'm very familiar with many of his threads.


I just stumbled upon this article on the V5MT1 I've never seen referenced, despite doing some considerable research.

http://tcase.rsgear.com/articles/1997_06.pdf

After reading, it seems to jive with everything I've heard/read about the V5MT1 except for the mention that GL-5 fluid is ok to use.

I've read several posts directly contradicting that, stating GL-4 is the only fluid that should ever be put in a V5MT1, GL-5 should NEVER be used.

Maybe it'll prove valuable to someone else too. I've attached it here as a PDF in case the link dies.

Same is true of the KM-145, for that matter, but I think that was already pretty well known.

In which case, I hope it helps someone out. As long as they fill it with GL-4, unlike I did 15 years ago...3 times...

 We Montero guys typically just want the AWD 4.90 front axle assembly, they can be had for around $200. That rear is likely 9" and definitely coil sprung.

 I don't do a lot of Mighty Max stuff but that's the suspension and steering i would run, it will require work though.

How about Montero Sport 16" alloys?  There are a few varieties.

PLH:

Thanks, your numerous posts have been immensely informative; I anticipate having more than a few questions for you once I actually dive into this project....


Nothing too exciting to report, the funds I've been planning to use for this project were delayed for about a month, putting things on hold; they should be freed up later this month, enabling me to move ahead.

I was able to take advantage of the 40% sale at the semi local pick-n-pull yard over the weekend, scoring a non cracked dash I've been searching for in the same blue as my interior, a replacement front passenger turn signal, and 2x windshield wiper arms from a Volvo 740 for a grand total of $32, which I was pretty satisfied with.

I had seen Volvo windshield wiper arms mentioned as a simple bolt on upgrade with far more common/standard 'J' style blade mounts over on mightyram50, http://www.mightyram50.net/vbulletin/showthread.php/6425-Volvo-240-windshield-wiper-arms

Happy to report the info was accurate, they're a near perfect match; the set I pulled were from a Volvo 740 I believe.

Hoping to order my D4BF motor by the end of the month and praying S Korea isn't slapped with some obscene tariff before I can get it landed stateside.

I'm wondering if any of you can help me in tracking down a set of wheels... I'm hoping to find 'NATO' style steel rims in 16"x7" / 6x139.7mm / 108mm center bore with workable backspacing.

I incorrectly presumed there would be plenty of likely OEM choices from other vehicles fitting those specs but am coming up pretty dry....

As of now, the leading candidates are:

These Montero steel rims that check all my boxes, but at $95/ea, $475+shipping for the 5 I want, seems stupid high for such basic rims....
 [ You are not allowed to view attachments ]
https://www.finishlinewheels.com/MITSUBISHI/MONTERO/2002/S-65787U20/

These Toyota steel rims look promising, are pretty affordable at $55/ea, $275 shipped for 5, but having the centers bored from 106mm to 108mm adds to the cost and I'm not certain the center bores would be conducive to a machinist's boring bar due to the fact that they're stamped. Being lugcentric, tt shouldn't really matter though.... Can anyone confirm?

The only other semi viable choice I've come across would be these stock Toyota Tacoma alloy rims. They're the only alloy rims I've found with aesthetics I like, they can be found pretty cheap on CL, but having the centers bored from 106mm to 108mm adds to the cost before bead/sand blasting/painting them.
 [ You are not allowed to view attachments ]

This however is all academic/research at this point as I'm not certain what backspacing I'll want after swapping in the wider MS rear axle and front suspension/steering as well as what front fender well clearances I'll need to contend with after the modest +/-2" lift I'm hoping to gain from the UCAs/HD Torsion bars and 235/85r16 tires.

Any educated insights/advice is appreciated.

I had to clearance my aluminum Trooper wheels to clear the larger axle center diameter of the Montero axle. A router with rabbiting bit made quick work of it.

More power for sure! I gained about 5-6 psi of boost and the EGT's are down about 100 degrees on the average. I haven't checked the mileage.

Post by: cdalejef on February 06, 2019, 07:56:38 PM
It's pretty much all across the board.

Not sure if it comes on sooner as it spooled up pretty quick before, it just pulls hard all the way up to about 3000rpm

Yeah, 2.5" straight pipe.

It is in the EGR block off plate.

Ok,has anyone done this swap yet. I haven't made it to the transmission part of my swap. I am in the process of wiring it now. I hope I done have any problems, the 89 ram 50 was automatic already, I bought a 4d56 with the automatic transmission already attached. I'm hoping its plug and play.
