- Never Far From Nowhere
Introduction:
When I bought my Trooper six and a half years ago, I got it for the primary purpose of getting out to explore the vast backcountry of Utah. In that time I have traveled thousands of miles of dirt with it, never doubting it would get me to my destination and back. I've done some mild modifications, lift, transfer case gears, and a few other odds and ends; but other than that it is completely stock. So when I noticed an odd noise coming from the engine a bit ago I was more sad than anything. At 234,000 miles, only around 50,000 of those being mine, I was hoping that the engine would last a bit longer. But, not knowing its maintenance history before I got it, I suppose I can't be too surprised. I diagnosed the issue as a rod bearing, so not an easy fix. I was looking at the prospect of either rebuilding the motor or getting something new to replace the Trooper as my primary exploration vehicle.
How it was when I bought it.

I spent some time thinking about it. The Trooper is nearly 25 years old; but it has been the perfect vehicle for me. It has plenty of power, capability, space, and comfort. And even looking down the barrel at spending around $3,000 to rebuild the motor; there isn't another vehicle out there that matches it for the cost. I'd dreamed of one day replacing the Trooper with a Mercedes Gelandewagen or a Nissan Y62 Patrol; but at this juncture they are a bit out of my price bracket. I could find an 80-series Land Cruiser for around what I'd be willing to spend, but in so many ways they're a downgrade from a Trooper. A 100-series is more in line with the Trooper, but people think they are gold.
At the end of the day, it really was a no brainer for me to dive in on rebuilding the engine. But by committing to that path, I'm also committing to having this vehicle for another five to ten years. That means it cannot be simply rebuilding the engine, this needs to be a comprehensive refresh of the vehicle. I will do this in the following phases:
Phase I: Engine Rebuild
The Isuzu 6V1D engine is a solid motor, particularly when mated to a manual transmission. Making 175hp and 188lb-ft of torque I've never felt that it was lacking. But, if I'm going to rebuild it may as well make some improvements. After reading through some very excellent posts discussing DOHC swaps and using the SOHC single chamber to gain a little bit better airflow and low end power I figured that'd be a pretty good upgrade to pursue. While reading about that setup, I also came across the idea of swapping the stock Multec-1 injectors with Multec-2 injectors from later model 3.2L and 3.5L Isuzu engines. This is supposed to increase efficiency and again, gain a little bit of power. With these small upgrades, I should be getting closer to 200hp and 200lb-ft of torque; not an insignificant increase! All the while, keeping the engine efficient and reliable.
While I have the engine out, I'll also be replacing the AC, power steering pump, alternator, clutch and all the associated wear components so that everything is as fresh and new as possible. I'm also going to be adding a secondary fuse block for all my add on accessories like the fridge and HAM.
Phase II: Exterior
What's the point of having a car drive like new if it doesn't look new? I don't have a lot of rust, but I will be eliminating what I have. With the rust gone, I think the Trooper would look excellent in Toyota Quicksand with black along the lower quarter. I also will be tinting the windows and replacing all the exterior lights with LED's.

For armor, I'll be building custom front and rear bumpers and modifying some Rocky-Road Outfitter rockrails I've been sitting on for years. Since I rerouted my exhaust last year, I'm also going to be building a new skidplate to protect the tranny and t-case.
I've enjoyed the Scepter can holder Carl built for me a few years ago, but I want to make some improvements to it and maybe build one that holds two cans. That way I can carry 10 gallons of extra fuel or five of fuel and five of water. I'm also toying with the idea of getting a 35 gallon Long Range Automotive fuel tank.
Finally, new badges. I figure I'll make some new slightly more modern looking "Trooper" and "Isuzu" badges. Because I have access to a vinyl cutter and why not?
Phase III: Interior
All interior lights will be changed to LED. I have a BlueTooth stereo at the moment, but I'm not too happy with it; so I'm going to find a better one. I have a iPad Mini mounted up for GPS duty, but I'll be plugging that directly into the new stereo via a rear USB port and using it more like a full "infotainment" center. I never use my CB anymore, so that's going away and I'll be upgrading my 25-watt HAM with a 50-watt unit. I'll be adding another 12-volt power outlet in the lower part of the dash and a few USB ports in the center console for charging devices.
In the rear I already have two 12-volt outlets on the passenger side, one of which is a dedicated port for my fridge. I'm going to put another outlet and a couple USB ports on the driver's side.
Finally, I'm going to put sound deadening everywhere. Every piece of carpet and panel that can come up will get sound deadening underneath or behind it.
Conclusion:
What's in a name? Everyone calls their Trooper a "Super Trooper", so I couldn't do that. I got to thinking; there was the "Fortress", the "Superfortress" and finally the "Stratofortress" in Boeings line of large strategic bombers. Additionally, the B-52 Stratofortress is the longest serving aircraft in the USAF inventory, and over its long history has gone through many modifications and upgrades to keep it relevant. And now it looks like it will be serving well into the 2050's, 100 years after it first flew.
This project will take time, but I hope to have the vast majority of it completed by next fall. And once complete, much like its namesake, the refreshed Stratotrooper should serve me well for years to come.
