I got a ton of questions for this. I plan on doing the same exact thing plus more. My mower is a 1996 Kubota G1900S, the four wheel steer version. First off, before I tackled engine mods, I took the belt drive fan off and replaced it with a SPAL puller fan. And to my surprise, it made the mower run hotter. So, told a few people what I did, and they said that it was moving too much air. I was like ok, so I bought a fan speed controller with no luck. If you know what the problem is, please let me know. I'm willing to try anything. So this is my plan after I fix the overheating. I have a K03 turbo I got off Facebook marketplace for a really good price. I'd like to get that installed first. I have one very important question. Is the cast iron manifold strong enough to hold the weight of a somewhat heavy turbo (11lbs to exact). Will it maybe need some reinforcement? I plan to also get the injectors bored out by a friend that specializes in mechanical diesel pumps. I also plan to get bigger fuel plungers to add more fuel per stroke. I also plan to take the injection pump apart and remove the shims, thus advancing the ignition timing increasing the fuel. Second to last, I plan to make a custom dash with a boost gauge, EGT, water temp and oil pressure. Also will probably add a glow plug light, oil pressure light, etc. Lastly I want to cut a hole in the hood to route a 5 inch hood stack. I don't plan to make a ton of power, but just a little more than factory. And if not, I really just wanna enjoy the turbo whistle. Any help would be super appreciated. Thank you so much!
Tried all day to get my injection lines removed. Came off the injectors fine, but getting them off the injection pump has not worked so far. Like yours the valve holder wants to turn but not the lines. Soaked in penetrant and beat wrench with a mallet, nothing.
@@blackiron1325 I am working on turboing Kubota D650. I hope to get about 0.3 bar (4-5 psi) Very interesting what boost yours are getting. What size turbo do you use? I got TD02 style turbo made by Mitsubishi, which is used on 0.9L petrol engine, but it has weird oem flange, so some modifying will be needed. Forgot to measure cold side, but hot side wheel diameter is 35.5mm (1.4"). Turbo is really tiny, but kubota d650 is small engine. I really hope it will spool and produce boost.
@@Valtra103 Sounds like a great project. This is an RHF3 turbo. It actually came off of a much larger displacement engine (2.4L if memory serves) but it does spool and generates some boost. I'm estimating its somewhere in the 2-4 PSI range.
@@blackiron1325 Thanks, i will try to make it as nice as I can. And it is cool to hear that even 2.4L turbo can be spooled. Now I just need to mount mine on the engine and hope for good performance. Will share when done. And I am always waiting for your updates.
@@Valtra103 Not much to update yet. My next goal is to redo the pipe between the manifold and the turbo so it will clear the hood. The powered bagger idea had to be scrapped due to lack of compatibility.

5 days later, still won't budge. Think I'll have to cut the lines so I can get the injection pump out.
Do you plan to add boost gauge?
Yes I would like to add a boost gauge to know if its really producing much, if anything .
