sound good man............I think ya have a keeper

I be someone knows how to hop up a Kobota

this summe I bet ya get better than 30 mpg

 

 

Man, that little truck is awesome. Nice work!
The Jakebilt looks pretty slick too!

 

looks graet man. wish i could do something like that.
i had an instructer in college that was in the process of swapping a 3 cylinder kubota into a geo metro, and making his own gearing for the tranny where it would top out around 65, while maintaining 70mpgs. but i dont know if he had ever got it built or not. im sure he has but dont know about milage.

 

I finally got the gauges installed after a mighty struggle. I have an autometer pyro and it looks like it is going to max out at about 950. I have the probe an inch or so down stream of the turbo, right after the exhaust flange. I know it would be better to have it before but this looked like the easiest way to do it and I am real big on easy. I think that 950 is probably plenty hot but should be alright since the fuel setting is right where Mr. Kubota put it. If anyone out there knows how to turn the fuel up on one of these I would like to hear about it just in case I get overenthused one of these days. The boost tops out at 8# at 1600 rpm and will not go any higher. Evidentally that is where the waste gate opens. It makes boost right off idle and when I am travelling down the road at 60 it pretty much just stays at 7.5 to 8# and the pyro a little below 800. I am thinking that if I adjust the actuating rod for the waste gate so it opens a little later I can get it up to 10# which might be a far as I should go. Starting out with 22 to Compression probably makes pretty high cylinder pressure. Turbo boost increases the fuel, it has a little pressure can on the pump which works a lever in the pump, I am hoping that fuel will increase at the same rate as boost and still keep me below the dreaded 950 degrees. It is not like some 400 HP Cummins where you can have high temperatures for short bursts. This thing is pretty close to doing it's best all the time so I don't think I had better get to carried away. Anyway if any of you wizards out there can give me any enlightenment on this deal I would sure appreciate it. Thanks much in advance.

 

shhot this sound pretty good actually........if ya go adjustin on the wastegate actuator do yerself a favor and get shop air hooked up to it and a gauge and adjust it that way so ya know for sure.....its easy to do

 

Sounds like a good plan . I have a good dial type tire gauge which I should be able to make work. It looks like the kind of project where I could lose parts, most of my projects are like that. Doing it that way you would think that you might get it right the first time and so cut down the amount of droppage and crawling around the shop floor. Thanks Jake

 

you will be suprised as to how little that actuator lickage move to give you full open

 

Good job, looks like a factory fit. and injoy the milage with!

 

Very nice work...
