I apologize for English, I can translate if you'd prefer in the future. Sorry for my late reply, I forgot to check this page.
I only know of 5 other Mitsubishi Jeep owners.たぶん at least a few dozen exist. But that is a guess. They come up for sale on ewillys.com every month or so. I am trying to make a network for non-Japanese owners to help each other, and perhaps reach our fellow Japanese owners.
What would you like to know about Jeep culture in the US? I bought my Jeep 1 year ago, but I've wanted a Jeep since high school (I am now 31 years old). I always thought that it'd be fun to have a car that I could wash the inside of with a hose when it got dirty. :)
The J54 is well liked by Americans who see it. I take it to antique car shows and drive it offroad with my local Jeep club (http://novajeepers.net). In fact, this weekend I had it offroad. I've attached some photographs.
Most are very impressed with its offroad capabilities. Many wonder how to buy one. Nostalgia と思い増す。
I have modified some things in my 1976 J54 (named Sergeant Betty because it loosely rhymes with CJ-3B). It has a secondary heated fuel tank and supply lines to run "straight vegetable oil." I installed disc brakes on the front axle and 11 inch drum brakes on the rear. I added vintage Warn lockout hubs. Also, my front axle has a heavy duty cast iron military differential cover, from an American MB or M38. It has a Bestop Tiger Top. I created a small circuit to use US style taillights (combined the turn signal and brake). I found a K&N air filter that fits with only a small modification.
I like my J54 very much. I hope to keep it a very long time.
I do have three problems though. I need to convert the oil filter from a canister type to a spin-on type. That way I can buy oil filters. Do you know of a kit to do this?
I broke a small dipstick on my injection pump, and am not sure how to find a replacement.
Also, my engine is sick. It revs very high and blows black smoke for 5 to 10 seconds when I first start it. Then the RPMs drop very low and almost stalls. If I lightly touch the gas pedal, then the engine overreacts and it revs too high, then lingers high a few seconds, then drops down too low again. It does this until the engine warms up. I worry that I have a governor or injection pump issue. Do these symptoms sound like a common problem for 4DR5 engines?
Sorry to trouble you with my problems. Sgt. Betty runs fantastic otherwise. Cheers to Mitsubishi for keeping the flatfender design so much longer than the US! Cheers for putting a diesel engine in it!
