Went and got me a V2203-DI today, time to get started on finding a 5 speed ranger (or possibly another small truck) to put it in. If anyone knows the best way to go about making an adapter plate easy, do tell. Sorry for hi jacking the thread, figured yall might be interested in what you've inspired

 

Hi gang, I've been busy for a bit with other projects but here's an update. Everything is still good to go, no failures or other issues. It is my daily driver, if I go somewhere I'm driving it! I have noticed, or I'm going crazy one, that the summer blend fuel is producing more power, it's a noticeable difference. I have also hooked up my A/C since my last post, yes it knocks the power down but nothing unexpected. It's a similar power loss as with any 4 cylinder engine, good cold air though. As for the computer, mine is powered up and functioning because I need it to make the speedometer work. I've probably driven it 5-6K miles now and really enjoy the little truck. I get 31 MPG religiously, that's at 70+ driving the crap out of it too! I am building a V2203DI for it, that engine should take the turbo better and get better MPG. More updates when they come..

Aaron in Deer Lodge, TN is putting the finishing touches on his 2203 powered ****** truck. Look him up or send me a PM for contact info.

Wow, those numbers are great. FYI, the 3.45 rear end ratio and 29" tires is close to a 3.08 gear on stock sized tires. That's what I'm going to use.


Don't forget the other thread on here covered the Kubota-Ranger conversion. He converted a 2003 Ranger, and he mentioned everything works, including cruise control. Well, I think the oil pressure gauge didn't work.

BTW, what did you pay for your 2203DI? I am about to pull the trigger on one up north for $850 shipped. Seems like a very good buy.




usedkubotaman, when I was studying the HP charts, the DI models made similar HP and torque, but used about 10-15% less fuel. That, and the lower compression ratio suggested it would be great for boost and MPG.

I am still searching for a clean extended cab manual truck after 1998. My brother decided he needed a Kubota Ranger, so he just bought a 1990 Ranger. We're about to start converting it. I already have the adapter plate, modded oil pan, and a Garrett GT1544 turbo. We're scratching our heads on the best approach for running the a/c compressor, power steering pump, and alternator. I'm also waffling on whether to use a more efficient, compact water-air intercooler, or keep things simple with a less efficient front mount air-air intercooler.

 

Turbo6bar,
Since the little Kubota's were only designed to have an alternator, a belt system to power all the accessories is perplexing! I came up with the serpentine set up and it works great. The only thing I would change (and will change) is the tensioner, the engine produces some type of low speed frequency that causes the tensioner to jump too much. I would use a fixed tensioner of some type.

Fuel MPG: The DI engines are built like the 5.9 cummins or most any other turbo charged diesel engine. The DI's have a pocket in the piston and the head is completely flat. The IDI engine have a pocket (pre-combustion) chamber in the head and the pistons are flat, bad design for turbocharging though it does make a huge difference when you add a turbo.

 

Having just found and registered with this sight, I chanced along this Bad *** conversation...
I Had no clue anyone eals did this swap other than that fellow at kinetic industry's..
I have a V2203 that I fit with a toyota trans... I went about it a lill different.. I Rea indexed the Toyota fly wheal to fit the kabota.. machined an adapter to center the flywheel to the crank shaft and hold the piolet bearing.. the adapter plate is laser cut.. .325 steel and the area for the starter milled down .125.. now it fit togather great.. the things that suck are stock Toyota starters can turn the kabota.. and i Feer the Rea indexed flywheel may be to week and fail in the future... so I am going to start all over and follow the rout of y'all...
My question is on the fly wheel..
is there a pressure plate that bolts up to the kabota fly wheel or must I mill it down and index holes for the pressure plate?

 

Hi, welcome to the "club"! I am not aware of a pressure plate that fits, I had to turn the diameter down to fit the Ranger bell, so indexing for the Ranger pp and clutch was easy.

 

Found a whole set up today that is bolt on... But at 600+ its a bit more than Id like two dump... I like the Idea of turning down the fly wheel, better hp Performance I am willing to bet... will be working on that now... What 5 speed trans is it yall are using.. and how do you like the spread of gear ratios with the kubota?

 

Welcome Ranchwest! Turning down the Kubota flywheel, depending on which on you have, is pretty straight forward. The one I'm using is heavy, real heavy, would be better if it was thinner so the engine would build RPM's faster, but works just fine. I'm using the original GM 5 speed trans and indexed the GM pressure plate to the Kubota Flywheel. I believe there are pics early in the thread of the flywheel and transmission.

 

Awesome work!!

 

Figure Ill share some pictures of my set up.. Also I am just going to get a Hightork starter and go with what I have.. If the re-indexed Toyota flywheel cracks Ill go back to the drawing board..
