S-10 Kubota Diesel Conversion
Joined Diesel Bomber today. Because of this thread. Thanks to one and all.
Bumped by here a few times when searching things diesel.
But until today when reading how this topic has real legs.
Count me in.
I have a 2006 Econoline super duty with a 6.0. And love it. Have gotten 22.7MPG as a best.
But I know there is real economy out there – and you guys are on to something!
My plan
Just purchased a Kubota D1402-DI-AE engine off E-bay. That was removed from of a Tractor.
At 1.4 liters it is smaller than what you guys have done. But after taking your advice and working on the Injection pump. And adding boost. I am planning a nice DD.
I am a bit a worried about having enough power to be a highway cruzer.
But I am going for it.
Will need to keep it light! Thinking standard cab short box 1998 & up Ranger body.
Attempting to go low buck simple. With real world every day usage.
Using a T-50 Toyota 5-speed (I already have 3 of them, and they are cool).
And thinking about a roots super charger (like the one I have on my MR2). To maximize what diesels do best. Low RPM Torque.

You're probably going to have a hard time getting a 1402 to produce enough HP to make a little truck drivable, it's just too small. If you want to put the time and effort into a swap (mine has been very much worth the effort) don't go any smaller than a 2203. Just my thoughts, hope it helps.
That's ambitious. It does seem a bit small but I guess so did the 2203 before anybody did it. Its already bought and it seems like you're taking the plunge on it so good luck. You should definitely start a build thread. I'd think the only feasable way would be to maybe run a splitter so you will always be able to run in the powerband. If you commute.and never need to go over 45-50mph I bet it'll work, I don't think freeway speeds will be possible

If you can get that kind of mileage out of a 6.0 it seems like you don't mind driving gingerly, it may work

YES YES
But after driving this new group of today’s gasoline powered economy cars.
That run and are tuned like a diesel.
The Chevy Cruze, Ford Fusion and Dodge dart.
All have 1.4L direct injection turbo engines. The have peak torque around 2000 RPM.
There auto gearboxes all short **** to keep them in the heart of the torque.
Get great mileage (for a gas engine). And are fun to drive!
Sounds like the car makers have been looking at whet the truck guys already know.
I have been testing this kind of gas engine for a few years at work.
And I feel confedent about a small Diesel doing the work.
If you get a chance to drive a New Ford Fusion. With the 1.4 engine – do it.
Its impressive Little beast.

I think this is what you're looking for... I don't have any other formats, but my machinist friend would probably save it to a different one if you need a specific file type.

Yep! Retaining the Jeep starter and clutch parts were the reasons why I kept the Jeep flywheel.

Thanks Red

For helping us define our trans adaptors.
I have 2 questions.
#1
I opened your drawing of the engine side. And noticed the bolt pattern on the engine side is not symmetric.
So when I view you’re drawing. Am I looking at the engine view?
Or is it as viewed from the Adaptor front face?
Not being critical at all. You did a ton of work here. Just to give it to us is more than required, Thanks.
I would hate to see someone make a mirror image of what the adaptor should be.
#2
How did you measure the bolt pattern with that level of accuracy?
Thanks again

The drawing is definitely the Kubota engine side.
Here's a picture of the back of both engines

And here are the adapters
Yes I will use the GT17 turbo on the DI engine, it should work fine on either.
Ok guys, got my truck up and running today. Runs pretty well but I have a few issues. First is a water leak that shouldn't be too bad to fix. Next problem is my idle. I started it and the idle.was a little high so I backed off the bolt that sets the idle and that slowed it down. It was idling several minutes and all of the sudden the idle slowly climbed to what I imagine to be about 1000 rpm. I revved it and let idle and it returned to idling slow. It did it again and revving didn't work. I put it in gear and lugged it and it idled right again. But then it'll randomly idle higher. Anybody experience this?
