Kubota V2203DI rebuild. Has anyone done this?
Just wondering if anyone has torn down one of these Kubota V2203DI Engines and done a rebuild? And if so how was the cost in doing so?
Thank You. :) |
I guess that is really a very complicated thing to do.

Hey Jester do you need a rebuild on your runner already? Or are you working on the second engine? I see rebuild kits on ebay for 6-900$ depends on if you get sleeves or not.
At the price we are paying for the engines I am not sure a rebuild is worth it. For me I would want to work out all the bugs of the conversion first, and if it is really an excellent complete vehicle, that I would want to drive for a long long time, then and only then would I consider a rebuild on an engine. Just a guess but a shop would probably charge $1k to $2k for the labor |

Just a guess but a shop would probably charge $1k to $2k for the labor But no I have not blown anything up YET lol. I will probably use one the turbo chargers that are recommended here turbo is a kkk k03 from a 1999 vw passat 1.8t gas 4cyl and try and keep my HP Hungry friend away from it lol. For some odd reason he thinks since it is a turbo and we can make a better intake then we can push 30+ LBS of Turbo pressure in the little engine and make better than 300 HP lol. So every time he mentions it I say no I will be happy with 20 LBS or so boost and about 100HP and 160 LBS of TQ as to what has been mentioned on this forum for the above given boost pressures. From what I have read on this forum if you start pushing boost pressures too high on the Kubota then you can crack or lift the head. I am not worried about the labor only parts and machine work that might be needed. As I can tear the engine down and re-assemble. I was just thinking about maybe having a fresh short block just in case of a major disaster lol. |
I've built a bunch of Kubota's over the years, they're not bad to build. I have not used the after market parts yet, they have just begun to produce those kit so I don't know about the quality. Kubota parts are very high, but like everything else you get what you pay for, build it right and it will last a long time. Note, Kubota does not use wet sleeves, they must be bored, last time I built one they only offered one over-sized piston, V2203 kits run about $1200.00.......

I wish they had removable sleeves but they do not so I guess it if it was too far out of spec it would have to be bored over and a sleeve installed. |

From what little information I have found it stated that they should not be bored more than .020 over?

I have never ran into one that had to be sleeved, they just don't wear that bad. I'm sure you could find one but I never have. They are well build tough engines! Even the way they have their crankshafts configured is an art. Most engine have main caps that hold the crankshafts in place, on a Kubota you attach the main to the crankshaft and then it slot loads through the rear of the block. You've always heard "4 bolt main" well Kubota engines are like having a that X100. :pca1:
I would have to do it myself as it looks like you remove the crankshaft as one would a cam shaft from a Chevy? |

I just remember reading it on one of the forums. Something about the Kubota that comes with a Turbo as standard equipment has a thicker head. I have no idea though. But to be honest it made no sense to me as to have two separate design heads on the same engine. That is from a manufacturing stand point.
And how how do you keep your EGT low enough when running so much Boost? As the most I have seen people on this forum run is right around the 20 PSI range for a very limited amount of time due to the EGT. All this Diesel stuff is New to me. Even FTE told me to forget everything I know about Gas engines and HP as it will not equate to a Diesel Engine. |
More air equals lower temps with a diesel.
One of my twins went bad, so I pulled that setup, and I'm now running the same turbo as FTE. The only time that I need to keep an eye on the heat is under 1800RPM. The turbo doesn't get into the efficiency zone on mine until a bit over 2000RPM. I'm working on a setup to address that. |
Hey RED, have you tried that larger I/C yet?
|
No, it's going to require all new I/C plumbing. I'm replacing my radiator next weekend, so I might get to it then.

What is the weight of a Kubota V2203 dry? What is the weight after all of the accessory brackets have been installed? I am wondering if this would be an option is something a little more aerodynamic like an F Body Camaro or even a Vette?

Welcome to Diesel Bombers.
But it would be nice if you would go here and Introduce yourself. Diesel Bombers Introduction - Diesel Bombers Then pay attention to what the thread is about and post helpful information or ask a question. Otherwise please by all means start a new thread. Thank You and enjoy the forum. |
I think the advertised weight from Kubota is 396lbs. I think that is alternator only. NOT the Carrier configuration. And that is the newest model year. I will have a weight on mine in the next day or two I will let you all know

sorry I put the weight up on my thread " Kubota into a cherokee" my engine weighed 462 pounds. That is sort of a not finished half accessories weight but full of oil.
