So, are they 3" diameter? Solo

So, looking at your intake/exhaust pipe routing, I am kind of shocked at the huge size of the main piping, versus the pipe size connecting to the turbo. It looks like 3" diameter? Is there much gain in performance with the bigger pipe, considering the necked-down size into/out of the turbo...

Absolutely! The one thing I have found during my own preliminary research is how critical EGT monitoring is. I was shocked to see how fast and how high exhaust temperatures went up when the engine was loaded hard and started rolling coal. Black smoke = higher EGT's, plain and simple. On...

Wow! This is Excellent! Thanks Mike, this is exactly what I was looking for. . . Solo

Looking at the Kubota part, there is a very sharp upward turn that is most likely due to space constraints. I think I can find the gaskets, but if you can provide the thickness of your flange that would be an enormous help. I do have access to fabrication and assembly facilities. Solo

Got it. So, the stock Kubota muffler flange that connects the turbo exhaust to the main exhaust pipe is pretty much a unicorn as far as I can tell from my research. I would really be interested in seeing what/how you milled a custom flange. Comparing it to the Kubota drawing, it has to be cut...

Ok, that's what I thought after going back and looking at some of the earlier pictures. So, are you using the waste gate on the turbo at all? The TD025 turbo has a max rotational speed of 240,000 RPM, so I would think that running at only 2100 RPM you wouldn't need it. Do you have any idea...

Hi Mike: Things are looking really good. Quick question: What is the part number for the muffler flange that attaches the turbocharger to the exhaust manifold? I am having a hard time finding it. Thanks. Solo

Thanks for the update Mike, but it's a little unclear where the connections are going. Could you maybe clarify them a bit? Thanks. Solo

Do you know which ones" Solo

Question Mike: What size intake and exhaust piping did you use in your application? Solo

Thanks for the reply Mike. I have been researching and collecting data on all the necessary parts. I can get an original OEM Mitsubishi TD025-M for $750 - $850, so that should shave off quite a chunk of the cost. Did you know there is an exhaust manifold available with a triangular 3-hole...

Hi Mike: A miracle happened today: I found this thread. Seriously, I have been searching and googling the internet for information on how to add a turbocharger to a Kubota tractor, without success. Until today. I literally thought I was going to have to go it alone. This is a Godsend...
