Build Threads / Re: Frankenstein- montero to monstero. LS swap
« Last post by tyeler18 on January 13, 2021, 09:24:05 PM »Fuel upgrades involved swapping what appears to be the original factory pump with a walbro 450. The sock on this pump was non-existent, im mildy suprised it even still worked. All the rubber had turned to goo.

Catching up to current, the truck was hit by a drunk driver while parked in front of my house at night. The rear axle was shoved into the front of the wheel well, trailing arm mount ripped off the frame, axle bent, suspension bent, and amazingly very minimal damage to the body. The rear bumper end was bent in and there was some small impact areas on the body, but the wide tires actually saved most of the truck.

As of this post I still haven't settled with insurance on this. While the truck is down it was time for some upgrades. The 76/65 turbo i've been using is way too small for a 6.0, I've been wanting a 78/75 since the start of the build. Christmas this year the gen 2.5 billet 78/75 went on sale, so I grabbed one. Going from a .80 A/R turbo to a 1.25 A/R will greatly help as well as gaining 10mm of turbine wheel size. This turbo has made over 900whp on multiple 6.0 setups as it is, which is more than I plan on making.

Out with the old, the compressors look similar since ones 76mm and the new 78mm. The exhaust housing is signifacantly larger.

I ended up trading the old turbo for a 5.3L swap for a buddies international traveall. I sold it with the 44mm wastegate planning to upgrade to a 50mm instead. I wasn't expecting the size difference of the 50mm to the 44mm. Space was already a concern and the height difference wouldn't allow me to fit this and close the hood easily, so I ordered a new 44mm gate and will be welding this to the new turbo hotside just like the previous turbo. 44mm left, 50mm center, tial BOV right.

Next was to fix the rear diff. Mine was beyond what I wanted to spend on saving, I wanted disc brakes ideally too. Gen 2 montero's are normally fairly common in the local yard, naturally when I need something there's none to be found. I contemplated buying a full truck just for the diff and any other upgrades I could scavenge. After some research it seemed the montero sport diff had potential to work, we pulled a 9.5" sport rear axle with 4.63LSD only to figure out why they wont work. The montero trailing arm mounts toe inwards as the trailing arms mount on the inside of the frame rails, the sport mounts have zero toe as the arms mount under the frame. There's enough difference that it won't bolt in, looks like the mighty max gets a coil spring rear upgrade and a 9.5" LSD. Over christmas I found a salvage yard in Colorado with a 96 SR being parted. 9.5" rear, disc brakes, 4.63 gears and a factory air locker, perfect for my truck. I paid just under $600 shipped and they included the e-brake cables, track bar, and gen 2 trailing arms to upgrade from my gen 1's.

We swapped the diff in over New years, now I'm just waiting to fix the trailing arm mount. I'm building a new 4" exhaust as the 3" that I built for the old turbo is too restrictive. 3" was a big enough pain to fit, this 4" is going to be even more fun. Luckily I made accomodations while building the 3" for up to a 5" exhaust so I have some work cut out for me.
