Kubota Ranger swap update
 
I now have 11,000 miles since I did the conversion and have had no problems to date. Fuel mileage averages about 28 on my oilfield route which involves 2.5 hours on the highway at 60 and 2.5 hours chugging around the oilfield with lots of stops and starts, about 15 miles. I never shut it off as I am never stoppped for more then 5 minutes. I made one road trip of 485 miles and got 30.1 mpg but the winds were not too favorable. Nearly all of my driving is in hilly terrain with the cruise and I'm sure that doesn't help. I did pep up the boost from 8# to 10#. Just shimmed the boost controller can with a couple of 5/16 washers on each side. Each washer worth one more pound of boost. I get to 10# at about 2300 rpm and it goes no higher. This has made a noticeable increase in power and dropped egt by about 75 degrees. I could turn up the fuel now and make more power but don't know how and don't much care as I have all the power I really need for my purposes. I think it may have made me one more mile to the gallon but it hard to say for sure. This little engine has steadily gained in power every since I started, even before the boost increase and the fuel mileage has come along commensurately. Haven't had a day yet that got to 80 degrees but it don't look like there will be overheating problems, the fan never comes on as long it is moving. I did put the hammer down one day and ran out of revs at 78 mph on my gps. No wind and no grade, it damned sure won't do it going uphill. I wrote this in the hope that someone might be interest in how this deal worked out. Probably not for everybody but I am well satisfied with the whole deal.:c:

i wish i lived next door to you jakebilt, your the man!

There is a clickable link with pics earlier in the thread. Not too good, but all I've got. I have been using Walmart TC-W3 2 cycle oil for fuel lubricity, think it works real good, but who knows? Does seem a little quieter and it has to help for lubricity. It is made to be burned so should not leave any deposits. That's the plan anyway. Thanks for your interest, I'm happy to reply to any comments or questions.:c:

Kubota Ranger swap update
 
The latest word on my Kubanger, I now have 17500 miles with no problems to date. Mileage is now consistently over 28 mpg on petro-diesel. I have been using home made bio-diesel, 50% most of the summer and that drops the mileage to about 27. The egt is a little bit cooler and I have just a tiny bit less power. Boost is still maxed out at 10# and with 50% bd I have a hard time to ever get over 900 degrees on pyro. I still don't know how to turn up the fuel, but am not too worried about it, I can pretty much go with the flow now and it is nice not to have to worry about burning it down. The cooling fan has yet to come on when I am going down the road and we have had a few days in the 90's so heating is not a problem. I plan on driving it indefinitely and it will be paying out at around 75000 miles at the rate I am going. Fuel cost on diesel is around 7.5 cents a mile and about 5 cents on 50% bd. After 3 years struggle I am now making good bd, 850 gallons so far this year. I have held off on running 100% bd since fuel cost isn't that big a deal but will give it a try one of these days. I hate to give up any power as I have just enough to get by good now. It is amazing though how much more power it has now then when I first got it running, it really isn't too bad now, I was little concerned to begin with, but determined to drive the damned thing regardless. "Never holler whoa in a bog hole." :w2: I have never yet went on a good road trip with good conditions, mostly just chugging around the oil patch with a lot of idling. I hope some of you find this interesting, I am really pleased with it and like to hear any commentary, pro or con. :c:

What a great project... too bad I don't have the capability to do this kind of work otherwise, I'd be giving it a try myself.

Great job!

jakebilt 08-09-2009 07:36 PM

It isn't any extraordinary capability that allows a person to do things like this. Just get a wild idea, start right in like you knew it couldn't go wrong, find your self in way over your head, then just slog along with grim determination for a few months and presto, there it is. Just a little re-engineering anjd your ready to go. Right now I am hellbent to build a steel guitar. Just can't help myself. I believe that anyone can do anything if they want to bad enough. May not be a good idea but what the hell. Some people spend their money on boats, motorcycles, golf carts, etc. It's just whatever trips your trigger. Charge ahead,:c:

jake, when i get my diesel jeep done im going to start on a diesel motorcycle. thanks for posting. i think when someone im the middle of a swap hits a point that they could give up, reading the things you post get them back in the shop and busting the tools out. thanks jake

I've been scanning the net the last couple of weeks looking for a good Ranger swap and yours is the best yet. I sure wish somebody would come out with a kit for a standard Ranger diesel install. There are lots of great swaps out there but no two are alike.

Have you given any thought to installing an intercooler on your engine? I imagine that would give you a substantial power increase.
