I myself would not feel comfortable spinning the Kubota that amount of RPM's for any length of time. But from what I looked at today a Bobcat with the Kubota V2203 are turning them at 2700-2800 RPM and the Skid Steer has a Governor of 3000 RPM. What was interesting to me though is that for the Bobcat and the Kubota V2203 they were only rated in the35 - 45HP Range but TQ was in the 150-200 Range naturally aspirated. So as you can tell they are TQ Engines not RPM Engines.http://www.bobcat.eu/assets/imported...rochure_EN.pdf

Just as a personal side note I was amazed at the advertized TQ numbers given for the little Kubota V2203 naturally aspirated. And with people adding a Turbo my gosh the TQ must be in the 200 to 250 range or better.

FTE and I have talked about this to some extent and FTE came to the conclusion that the 2000-2200 rpm range is pretty ideal. To get the information you need you can use this Gear Ratio to Speed Calculator Gear Ratio Speed Calculator.

 

My ranger is 2450 at 75mph. Honestly I wouldn't run my truck at that rpm for an extended period of time, if I had to slow down to get 10mpg better fuel economy I would. To me it just feels like I am really winding it out at that rpm, but that's just my opinion.

 

on some of our highways if you run 75 you are not keeping up with traffic. Sounds like the 3.08 should be a very good ratio. With my current tire size. We will see in a few weeks. I hope to come out at about 2250 at close to 80mph

 

That would great! Where I live I only have two miles of 75mph speed limit and then it goes down to 60mph, so I couldn't justify re-gearing to get rpms like that. How much does that cherokee weigh?

 

My nicest Cherokee weighs about 3500, with me in the cab I am going to try and put it on a diet. This is for 2wd base line model, no electric windows. My Dakota is another story at about 4100 or 4300 with the camper shell I can't remember
I was wondering if you have a # for Lenards diesel? I can not find a Lenards. I found lots of Leonards diesel. or what specific city in CA he is in?? I would like to get the oil pan coming. Does Lenard know what part # to get? What about oil pan bolts, do you have to change those as well?

thanks

 

Sent you the information needed. And yes you will need new bolts but do not worry they have them.

 

I talked to Sam today, we just bought two more motors. hes not sure he has any used pans left, just new ones.

 

Hey Gaines12 well if it has to be new so be it. If you don't mind my asking how much is he charging for an engine? and what do you get. I saw some for sale, with no starters, alternators etc. etc.

thanks

 

I didn't know sam was selling engines... although I just got him in touch with some good sources so he can buy more motors. what are you looking for? theres lots of small Kubota motors and some that are a little bigger than the v2203 more like a 4bt

And diesel Xj if your looking for an adapter I have one left. Jestergrin is buying one of the 2 extras we made.

 

Also Sam does have a site its :https://parts-barn.com/index.php/ If you call him, mention my name, I talk to him quite often and we trade information about these swaps a lot. He tried to keep his website up to date with all parts that he has but their not always up there because hes still new to it
