Cool, thanks Mike, it's a great place to start. As always, appreciate your help. Solo

Thanks Mike. Solo

Hey Mike: Any idea what the torque specs are for snugging down the turbo to the flange? Solo

My apologies for the long delay in posting the next steps. After looking at what I had decided to do with the oil supply and drain lines, I realized it was not optimum. This is one of the hardest parts of the build, due to the fact that there are so many ways to achieve the same thing with a...

Cool. Thanks Mike. Solo

Yeah, I've been looking through all kinds of sites trying to find nylon or Teflon fittings for this purpose but haven't been too successful. Can you reveal the part number and where you found it? Solo

Hey Mike, quick question: Did you say you machined custom fittings for the engine block oil drain or are they off the shelf? Solo

Boy, don't I know it. That's exactly why I'm even attempting this project. We had one of the worst winters on record this year, and even though my Kubota got through it, it struggled. If I can at least get back 3 or 4 pounds of boost, it will put me back to sea level (14.7 PSI), right now I'm...

Ahh. . . gotcha. I missed the emphasis on the cracking. It's a very good point and a complete unknown. All I can do is run it and see what happens. I may need to find a way to support it in the future. Great comments from readers help refine the process. And I would have to agree, this...

Thanks Dan. Great advice. I think I will look into that. Always appreciate input from experienced readers. Edit: After doing some research I realized you were right. This fitting is not a tapered thread and relies on a copper or similar washer (which I didn't have) to seal between the turbo...

Hi Dan, thanks for the comment. The fitting I was referring to is the BSPT threads on the original oil pressure sender. Not sure what you are referring to with the metric fitting? The fitting that screws into the turbocharger oil inlet? Everything else is just 1/8"NPT threads on the...

Hi GrizBota: I thought about the issue of rotation as well. I think I'll be Okay because the direction of rotation is tightening if it slips, plus, I honked it down pretty tight. Thanks for the comment. Solo

Sounds good. Thanks Mike. Solo

Yup, lol. Quick question: do I need a restrictor fitting for the oil inlet, or just a standard? Solo

Sorry for the tardiness of this post. After checking the fitment of the basic turbo and exhaust manifold, the turbo was removed from the manifold to be prepared and permanently installed later. Then the real work began. To say this endeavor is difficult at best is a gross understatement...

Hi Mike: Thanks for the clarification. Apparently, I fell into a very deep rabbit hole. I think I see now where my logic was flawed. My apologies for the confusion. You definitely have better resources and knowledge in this area than I. Your patience and guidance is still greatly...

I measured them the best I could. Measuring is not that accurate though. If you look at the picture, you can see the tapered threads on the original oil sender unit are tapered BSPT threads. The fitting on the right is a standard American NPT thread, and you can see visually it is bigger than...

So this is really frustrating. I received all of my fittings today to hook up the oil system to the turbo, and come to find out, the 1/8"NPT fitting for the engine block is the wrong size! I guess the oil pressure switch on a 2501 is a different thread size than a B2650. Damn, back to the...

Cool. Thanks Mike. I'll keep you posted. Solo
