Ive been lurking these forums for awhile, coming from a DSM background. I love my Montero (97 ES model, 5 speed), but it is rather underpowered for its weight.
After some research, this engine is very closey related to the 4g63, specifically, with the Evo 4-9 oriented models able having the same cast deck, just in wideblock RWD format. So 4g63 parts bolt right on.
Anywho, after more research, the electronics in the 4 cylinder Montero are very similar to th 2000-2005 3g Eclipse schematics. And those later model ECUs are flashable. The drivetrain also shares quite a bit with overseas Tritons and Pajeros, but the closest find here is the 94-96 Mighty Max which has a SOHC 2.4 wideblock and simpler ECU.
My idea is to swap in flashable 3g Eclipse Ecu and Maf, custom 20g turbo kit and tune for 8psi. I may be in over my head but I have:
-Evo T3 Cast Manifold and 38mm wastegate -Mitsu TD06h-20g turbo -Evo 8 Ecu and Maf( Will sell for 3g flashable Ecu and Maf) -Evo 8 fuel rail and FPR -Subaru 440cc Injectors- High Imp -SAFC2 (Will sell for water injection) -R35 GTR Mitsu BOV -FMIC
On top on that, I will need a stronger clutch. Any other suggestions? Anybody else with experience? I only see turbo 4g64 Tritons written over on the Thai forums...

... On top on that, I will need a stronger clutch. Any other suggestions? Anybody else with experience? I only see turbo 4g64 Tritons written over on the Thai forums... I'm not exactly sure what the point here is. If you want more power, get a Sport with a v6. This seems like a lot of trouble to go through to turn a REALLY slow overweight, top heavy vehicle into a moderately less slow overweight, top heavy vehicle. SUVs are not race cars. Anyway, if I remember correctly the 4-cylinder doesn't use the V5MT1 5-speed that the 6-cylinder does, I believe it uses the older 5-speed used in the Montero. If I'm correct, the older 5-speed was not a particularly strong transmission and I've gathered over the years isn't a good choice for anything FI. If I'm incorrect, and you actually do have the 2WD version of the V5MT1, that is a heavy, cast iron case transmission that doesn't shift very quickly. Honestly, if I were going to go through this much trouble and invest this much money, I'd start with a 2WD 6G72 with the AW3 A/T. Rodding trucks is not the same as rodding cars; there is NO SUBSTITUTE for displacement in big, heavy, not very aerodynamic vehicle. Edward

I suppose I did make it confusing. I already have a 97 Sport ES with 2.4 4g64 motor and 5 speed R5m21 transmission.
I love it but its slow. It cant get out of its own way. The 6g72 swap is not feasible and the common air intake and exhaust wont be worth it dollar/hp. This turbo setup is costing about $1000 (rough estimate) for what I will assume will be close to/above HP over the 6g72 configuration. What is that, 180tq/ 200hp to the wheels? I can do that on boost.
The 4g64 motor is a widely used motor and also is commonly turbocharged among 99-05 Galant and Eclipse enthusiasts. Parts from the factory 89-07 4g63t bolt on to the 4g64.
I know it can be done, and I have a good idea of what I need to do. Im inquiring as to whether or not any members on this Montero forum has done so. I would gladly accept advice...Ive seen it done on the V6 already.
The most racing I would do with this rig would be out in the dunes or desert flats. Or against V6 Monteros, ha.....kidding.

Im mainly using resources gleaned from 2000-2005 3G Eclipse 4g64 turbo conversions...and I dont mind the constructive criticism but I have no V6...and the trans for the V6 is even more rare. If I blow a trans on the 4g64, I can swap in a Mighty Max or Starion or Triton wideblock trans.
This Montero is a strange one for sure, with lots of potential.

That power figure is with a quarter tank, driver only, and when all the planets are aligned . Im only kidding. I have the 3.0 v6 and wouldn't mind a little more get up. Well power is power is regardless where it comes from. The issue however is when. Available torque on the v6 is low in the rpm range whereas max torque on those turbo 4g engines don't kick in until 3500-4000rpm. What about a 4G setup and use something like evoscan. Using a mivec head and reflashing with that as well could be the ticket. They do use the n/a version in the trucks and SUVs so it isn't unheard of or an impossible feat. Being a manual would have its benefits as well. You could probably find a heavy duty clutch overseas that would work. Im not familiar with these manual trans however.

Thanks for the replies...
Yes, people overseas have been and still do turbo the 4g64 truck engines in the Mitsubishi L200. Just joined a page on FB but its all in Thai...lot of pics tho.
I want to keep the stock motor, but a Evo 4-9 head will bolt on, but requires changing pulleys and building custom manifolds as the exhaust would now be on the driver side.
I absolutely want to use Evoscan to tune this truck, but not sure if the 97 computer is compatible. Have read that the late 99 models may be good, but what will definitely plug-and-play is the 2001-2005 Eclipse Ecu/ Maf and the Evo 8 Ecu/Maf. Ive decided SAFC2 wont cut it for drivability..
Even though I have the Evo 8 ecu, I decided to sell it and find a 2005 Eclipse ecu and Maf and use Evoscan from there. There are modified (turbo) ROMS for the Eclipse, which also uses a NA 2.4 4g64 engine.
Only issue I see so far is placement.... all the turbo 4g64 trucks Ive found are topmount tubular setup with the turbo on top, whereas mine is a cast manifold, bottom mount style like the Stock Evo...

Need to learn to speak Thai. J/K Some web browsers will translate for you, sorda.
I can't say about the 97-99 montys. What about ditching the stock ecu altogether. A completely customizable setup would be the way to go.
You worried about there being room or heat? There isn't an aftermarket manifold available?

I would recommend just getting a AEM EMS Version 2 if there is one avail for your application. There are a few 3000gt vr4 owners that are doing a 4g swap and that ecu along with a auto tranny are what some are using. There is a guy on the 3si website that is working on the 4g swap with a 5 speed that you may be able to hit up for info.His name is Josh. here is a link. www.3si.org/forum/f1/4g-swap-654617/ Clay

Clay I have two or three AEM FICs, BTW, so if you're interested in one .... One of them is brand new. Flashed it but never used it. A Boomslang harness for the ECM would also be helpful. I think I've been talking to Rustin there. A straight-through makes wiring the FIC in very easy and very simple. BTW, all of mine are FIC 8's. Edward

Jondoe, I went back through your original post. If you're going to do this, let me know before you start looking for electronics and I'll go through my boxes. I may have some of the stuff you'll need and you're welcome to it. I was going to dump a bunch of stuff on ebay, but ....

You sound just like me except I have a Nissan Xterra that is a 4 Cylinder 5speed and I am wanting to turbo it too lol. On topic I will say this, why not get a turbo kit for the motor you have. And if one is not out there just yet why not custom build​ one? It's easier than people think. And with it being a 4 banger that makes it easier. Also another vehicle to look into for parts and figure this out is the 1997-1999 Mitsubishi Eclipse GS Spyder they apparently also had this motor in those as well.

That would be something worth looking into.
