Gen 1 Montero / 2.6L G54b Turbo Swap Tech
« on: May 23, 2018, 06:17:58 AM »
Starting this thread as a resource for G54B turbocharger installation onto a stock 2.6L Gen 1, focusing on directly swapping over turbo TBI G54B parts for a "low boost" build.  A high boost forged bottom end, port injection manifold, etc. would be the ticket, but this is a budget build list.

Please post any info, tips, or issues you ran into the way during a turbo install. Will update this first post as info comes in!

Gen 2 Montero / Gen 2 Engine Swaps - Knowledge Dump
« on: September 12, 2017, 05:13:50 AM »
In trying to determine all the various engine swap possibilites for a Gen 2, I didn't find a single thread that compiled all the info for all the various swaps possible (unless I missed it!) Making this thread for a knowledge dump of resources and experiences on engine swaps into Gen 2 vehicles. 

General Engine Info

Gen 2 Montero / SR Fender Flares on LS
« on: August 29, 2017, 07:25:04 AM »
Is it possible to swap the SR fender flares, bumpers, and ground effects onto an LS model?  Or are they integrated into the actual fender?

Looking into buying an LS but I just love the SR body lines!

Gen 1 Montero / Gen 1 Shifter Refresh - Seals & Springs
« on: August 24, 2017, 04:57:20 AM »
My new to me 1985 SWB Montero has some play and slop in the shifter assembly that I'm looking to address.

The seals that fit from the shifter and transfer case lever are loose and I believe dirt and water was getting into the gearboxes, based on the fluid color. 

Looking for info on how to "refresh" the shifter so it has less play, returns to neutral consistently, and shifts crisper.

I found in CAPS the following parts, but I'm having difficulty finding any for sale.  Are these all the parts that are needed to refresh the shifter assembly?

I've been owning (more wrenching than driving) Mitsubishis since I was 15, and I still have my first car in the garage, a 1990 Eagle Talon TSi. 

Over the years I have owned:
-1995 Eclipse GST
-1992 Eagle Talon non-turbo
-1999 Eclipse GSX
-1999 Eclipse GSX #2 (http://bringatrailer.com/listing/1999-mitsubishi-eclipse-gsx-2/)

And still own:
-1990 Eagle Talon TSi (My first car)

-1992 Galant VR4 #367/1000


After getting suckered into the Mitsubishi offroad scene by the Auto-Offtopic podcast crew my girlfriend and I are now addicted to all things Montero (damn you!) .  Brad and Andrew promptly got me up to speed on what to look for, and ADD helped give a little push as well! 

Browsing craigslist nationally, I happened to find this beauty https://saginaw.craigslist.org/cto/d/1985-mitsubishi-montero-2dr/6215049037.html and promptly picked it up.  It is a 1985 2.6L 5-speed with 132k miles and no body rust. 

The person selling the car still lived in Oregon, but his cousin was keeping the vehicle for him in Bay City, MI.  Long story short, the seller was up in the mountains without service, but we somehow worked out a deal with his brother and cousin, and drove away with the truck and title!  The ride home was interesting, as this was both our first time driving a montero.  Upon getting it home, I noticed the throttle return spring was binding and not allowing the weber carb to fully open to WOT, only two of the plates were opening.  Fixed that up and now it drives quite nice!

It appears to have only been in OR from 2011+, and before that only in CA.  It is nearly rust free, only surface rust on some subframe components.  It has a weber carb that needs tuning, and some toyota 15x7 wheels and 31x10.5x15 tires, other than that it is bone stock.  I will be working with my new-to-mitsubishi-wrenching girlfriend to restore this beauty to its true glory.

Plans are:
-Maintenence catcup: all fluids, belts, plugs, wires, brakes, etc.
-New KYB shocks (can't beat the price)
-Newer 31x10.5x15 tires (current ones are very very old)
-Exhaust needs to be replaced, maybe a header is in the cards from DG headers in CA...
-Keep it stock appearing and drive it!

Check out my IG @engiekev for pictures and videos of the truck! 

Hope to keep this truck alive and maybe get another Gen 1 or two ;)
