3000-3200 would be nice if for nothing else an Oh No RPM range. As in get out of the way speed. :scare2: But I am not sure if you can push the Kubota much over 3000 RPM even though I have seen 3000 RPM numbers for the Skid Steer. But look as I might I have not seen a Red Line RPM limit posted for the Kubota V2203 Engine.

I know redveloce is pushing 3500 if I remember right

3500 WOW Thats moving along :running:

But I am sure it hurts in the MPG department.

Well adapters are supposed to be done tomorrow hopefully! So maybe by this weekend, I think these motors are probably making more like 140 or so but the torque should be really high. That's whats so good about these motors. got my turbo all cleaned up and in the middle of reassembly now I took some detailed sideways pictures!

Well I have a testament to how strong these motors Are. I was playing around in the woods today a started to ford a creek I have a few times before and. I forgot about the rain we have been getting. Water went over the hood befor I could stop and it was too muddy to back out . I made it al the way through and and out the other side I opened the hood and the air filter had completely collapsed in on itself. I left the truck running while I removed the filter and I noticed the exhaust was steaming. I reved it a little and it started to miss I pulled the cold side inter cooler line and water flowed out :argh: I reved it with the line disconnected and blew about half a gallon out. Put it back together drove the 5 miles home and its perfect Pulled the intercooler and dumped another 1/2 to 3/4 of a gallon out.
That's real water injection lol who needs a pump

For a second there I thought you were going to say you turned the little Kubota 5000 RPM :scare2: . But good to hear. The main thing is you did not let the engine die. Then you could have been in real trouble. But if you keep a Diesel running they will amaze you. I went through about the same thing in my 93 Freightshaker with a little 3408 Kitty Kat 13 Speed 4.10 gear back in 93. :w2: And it had No Governor:hellox: That Truck would Run.:scare2:

They don't recommend that in the manual you know? haha hopefully it wasn't to hot you could still do some damage by the quick cool down of all the parts. glad you made it out though

Thank You for that information Rangmar. I went and picked up the Fram 3976A this evening. But I have no idea what the A stands for? And I removed the part that puts the oil filter along side the engine and moved it to the front. I will say this those machined parts on the Kubota are sure nice.

Sorry what I meant was please let us know what spring to get to achieve the 3000-3200 RPM of the Kubota?

Just wanted some input on what you all think the adapters are worth, a lot of people around here are saying 100 but that seems a little steep to me. Now of course I know you guys want the cheapest price possible. But id appreciate some honest input. Still not quite down maybe by this evening. They are one piece precision machined and will come pre drilled and tapped for an EGT gauge. :humm:

I actually think FTE is right. As I also feel 100-130 HP and 250-300 LB's TQ.

I think 100 is more that fair for the adaptors and hopefully I will get it on the roller next week before I leave for Georgia

to those of you running the ko3 turbo..... how did you connect the oil feedline to the block? I have the line from the Passat but it takes a weird fitting, can I change the one on the turbo or what did you all do? also the line I have is almost all steel and I need a flexible shorter one

I brazed a barbed brass fitting onto the steel line and then slipped my plastic air line onto that held with a hose clamp. I use air brake line, like off an 18 wheeler, for oil line. There are pics in my thread.

I used a 1/4 npt fitting to a 5/16th compression fitting ( hard brake line ) and then a compression fitting to the vw line. I'm using the plastic air lane with reinforced compression fittings for the vacuum pump oil feed

So that I can get the plumbing straight to start with Oil Feed is in the center back of the Vacuum Pump and what looks like the top bolt is the Oil Return to the Valve Cover and the other outlet on the bottom is the vacuum to the Brake Booster Correct?

On the Oil Feed on the Vacuum Pump did you use a Banjo fitting?


And FYI We are all on Pins and Needles waiting for the outcome on the Dyno?

i have been trying to find a machine shop to help me with some machine work for a swap. can you help ?

---AutoMerged DoublePost---

or know any ideas on who to ask?

Hello everybody,
I guess I am joining the club....
I just cant let you guys keep all the fun for yourselves.
I noticed that there are a number of you located near me.

Rangmar
I live on Whidbey and have been following your-and others-V2203 builds. I have been saving money and am about ready to buy the engine. I noticed you commute from Darrington and work in Lynnwood from your thread. I have a 2001 Ranger 4x4 5 speed, pretty much the same as your set up. I am planning on turning the kubota flywheel to fit the ford pressure plate and building the adaptor here in my shop. Is there any chance I could meet you and take a look at your setup? I dont mean to impose but it sure would be nice to see one completed. Let me know, if you are busy I can understand that, especially at this time of year.
Thanks,
Dimitri

Update

Finally got around to changing the gov spring , now I can rev 3000 rpm. And I can get 27 psi of boost at 2700 rpm. Egt won't go above 1100 degrees and its way more fun to drive

Here are some specs on the k03 turbos I've found on another site

"I'm going to list each turbo model, what its fitted to, and its compressor/turbine specs along with maximum power (although these figures are probably in silly nonsense US wheel power, or perhaps borg-warners recommended power output, its still useful for comparison)

K03-005 - Standard fit on ALL cable throttle B5 1.8T's INCLUDING the 180hp AJL engine.
K03-029 - Standard fit on Drive-by-wire B5's and most B6 1.8T's bar the "190" model. Similar in specifications to the normal K03 fitted to Golf/A3's
K03-073 - Standard fit on B6 190 model. Similar in specifications to the K03s fitted to Golf/A3's
K04-015 - Not standard fit, Borg Warner turbo designed to be a direct replacement upgrade for the longitudinal 1.8T.
K04-020 - Standard fit on the TT/S3
FrankenTurbo F4h-l - hybrid, see 'zine thread.

K03-005
Compressor Size: 36/50mm
Turbine Size: 36/45mm
Approx Power Rating: 150HP

K03-029
Compressor Size: 36/50mm
Turbine Size: 40/45mm
Approx Power Rating: 160HP

K03-073
Compressor Size: 38/51mm
Turbine Size: 40/45mm
Approx Power Rating: 190HP

K04-015
Compressor Size: 38/51mm
Turbine Size: 42/46mm
Approx Power Rating: 210HP

K04-020
Compressor Size: 42/56mm
Turbine Size: 42/50mm
Approx Power Rating: 260HP

Franken F4h-l
Compressor Size: 40/51mm
Turbine Size: 42/50mm
Approx Power Rating: 240hp


So there we have it. Shows us the reasonably readily available k03-073 turbo is a nice upgrade without going to the expense of a new k04-015 too."

We are all on pins and needles on the Dyno Report?

So at 3000RPM does it sound like it is going to EXPLODE or as others say the Gerble is trying to escape lol.

And Thank You for the information as always. :)

I tried to schedule one today but they were booked. Ill try next week when I get back.
At 3000 its still not bad but I wouldn't want much more than that. Fte reved his to 3800!!!!!! Today. Lol sounded like a airplane over the phone when he did. Lol

Did you hear the Sonic BOOM :scare2:

---AutoMerged DoublePost---

Rangmar I for one will look forward to the Dyno report. But I know that you will not keep your 3000 RPM Governor Spring now that you have heard the Plane lol.

Why do I keep thinking The Plane The Plane The Plane lol.

Hi guys, I'm new on here and wanted to tell you how awesome you guys are! :tu: After reading everything that I could find about swapping Kubotas into Rangers, my wife is allowing me to start the planning/saving phase to follow in your footsteps. Keep up the good work!

Rangmar, were you able to get the Ranger on the dyno? I'm really interested in hearing those results.

Im going to try to dyno in may, we have a diesel club in Missouri and it only costs $35

Did you get yours running correctly? And if so what did you nail the trouble down to?

Its running pretty good now! still think I could get a little more out of it, I changed my governer spring but I still think it could stand a little stiffer, wish I knew my RPMS I need to get that sensor going now that im in OKlahoma at school and always bored

" TINY TACH" for a quick easy accurate diesel tach, $125, and you can take it with you to your next project they work off injector line pressure pulse and 12vdc. MADE IN USA. I really like mine a lot. If I can get my OE dash tach to work that would be great, but for getting up and running quick and easy This little TinyTach is hard to beat.

Look at post #23, Rangemar used the crank sensor, I used a 2 wire ABS sensor in the same location with notches on the pulley wired to the factory tach. Ten bucks for the sensor and a little effort , save a lot of $$ and have a factory setup.

FTE where can one find the Sensor for $10.00?

My local discount parts store, autozone has it for 13.00 napa 16.00, or free in my case. it came out of the rear axle I swapped out.

Well today is the day. My appointment is at 1 for my dyno run

We are on Pins and Needles. :)

98 hp @ 2200-
278 ft lbs @ 1800 !!!!!!!
Hp peaks at 2200 and stays almost perfectly flat to3000
Tq peaks at 1810 and doesn't drop till 2700 and was at 263?@ 3000
[color=grey][size=-2]

---AutoMerged DoublePost---

That's fantastic! If it's 98 H.P. at the wheels I wonder what the actual crank H.P. would be? Thanks for putting up the video. :tu:

Muhahahaha!!! :jump::yeah:

Thanks, I think after seeing how flat the graph I think the limit was were the fuel screw was set it climed very fast and leveled off almost immediately and stayed flat till 3000 I still have a long way to go on the fuel screw. I hit 27 lbs of boost at 1150 egt

Rangmar that is GREAT. But for some odd reason the video does not work for me? Ok I got the 2nd vid to work. :). Ok it was me both vids are the same lol. But still GREAT WORK. Who would have thought with a little turbo and a bit of turning of the fuel screw they would work this well.

I Forgot to ask was this with the Nitrous Oxide or without? :)

That is awesome, getting very excited,if I can get those numbers or close that would be 22 more hp and 186 more ft lbs, then the current 1.8L gasser in my Ford Courier. Thank you for all your hard work

Good stuff. Congrats. I don't have the band width to watch the video until I get home. Are you planning any more adjustments, or changes?
Thanks for sharing your results

Great results! Now I need to do the same to see how my setup compares.

Thanks for all the input. I have to pull the exhaust manifold to replace the manifold gaskets. I'm planning on having the manifold and maybe the exhaust housing on the turbo ceramic coated.i just ordered the gaskets and a 90 degree t-stat housing for mine from Sam at Leonard's diesel I plan on having powerstreering soon and already planning the next truck
