1991 Low buck Montero build

[4D55 Performance]

I recently purchased a 1991 Montero LS with a 3.0 V6 and automatic transmission. The plan is to create an expedition vehicle on a limited budget. I will do my best to document all the repairs, upgrades and modifications along with the costs.

What I have to work with:

-1991 Mitsubishi Montero LS (LS was top of the line)

-3.0 V6 engine rated for 139 hp and 172 ft lbs torque.

-Aisin Warner A44DL 4 speed automatic transmission (Did you know this is same tranny that was Toyota vehicle so this tranny with bolt right up to NP231 and other jeep and toyota t-cases. So, bolting up a doubler or an Atlas would not be a big deal.)

-KM100 Transfer Case

-9" coil sprung, solid rear axle with LSD and 4.62 gears (ARB and Mitsubishi both have air lockers available for this axle, most 1992-2001 Montero were fitted with a rear locker which is a direct bolt-in third member.)

-8" independent suspension front axle with double A-arms, torsion bars and Aisin auto-locking hubs. (ARB makes a locker for this axle. Gearing solutions are available for both front and rear axles if needed through Mitsubishi.)

-Driver side suspension seat from the factory

-31x10.50R15 BFG KO's

-Power Sunroof, windows, A/C, inclinometer, new tires etc.

-Roof Rack

-No Rust


My Plans:

-Dual bouncy seats

-Airflow Snorkel

-Aisin manual locking hubs

-Camp Chef Stove/oven/grill combo

-Custom drawer system

-33x9.5r15 BFG KO tires and

-5.29 gears

-Mombossa Roof Top Tent

Here she is, she has the extremely rare 2 tone paint job and rare alloy wheels.

Build Costs
Vehicle $2000
Idler Arm $12
Roof Top Tent $300
