So I have been wanting a turbo on my 1100. I live at 5800ft and it really struggled. Kubota offers the 1105 with a turbo so I knew it could handle the pressure. However, I thought the SWAG kit was WAY overpriced. I started doing as much research as possible/necessary to see what I needed. I have an employee that does turbo additions on automotive applications so I was not totally blind to the process.
I was really worried to get the correct turbo so I broke down and purchased one from the guys that make them for SWAG. They charged me $800 for the turbo. It is just a KP35. They sell for about $200 on eBay. Once I had the turbo I started to make paper cut outs of the turbo flanges that I traced and cut out of 1/4 inch plate. I ordered a few 1 1/2 turbo silicone pipes to make all the connections. I bought the fitting from kubota that they drain the oil return into rather than pull the oil pan. Turns out it is the dipstick hole for a different application for the motor. That saved me about 4 hours and if it works for Kubota I thought it was a much better way to do it. I had to have one pipe bent at a 90 to mount the turbo to the exhaust manifold. In a few hours of welding the new exhaust and flanges to the hose nipples It was done and running! I had spent nearly a month of home work getting all the hoses and fitting together so I didn't have any surprises during fabrication and install. So, long story short I have never been happier! It Runs fantastic now. Actually has some throttle response and will gain speed up a minor incline. Now that I know what I do, I could have done this for less than $450 and a few hours labor! I am going to do some additional piping changes for appearance
