That fits in there pretty nice, looks really good. Did you have to make that manifold hieght extension?
Yes the extension is 35mm ID and 1/8" wall, hoping it takes the heat. I will build more support in later. While the turbo looks heavy it is lighter than the original muffler it replaced that had zero support other than the manifold. I truly wanted the turbo to bolt directly to the exhaust manifold but then the oil drain would have to go down to the oil pan. Remember I didn't want to hack the pan and couldn't uncover the factory oil drain for this block which I believe is the dipstick tube access (although covered by the tractor frame rail). Turbo flange is different bolt pattern than the exhaust manifold also. I suspect the Bobcat manifold is a spendy unit. Another problem I encountered is the fuel tank shield, I couldn't sneak the turbo in under it without modifying it, also the reason I went with a pedestal mount. My air intake pipe is mounted very rigidly and the short intake connector will act as more support and hopefully vibration protection.
I used the valve cover for the drain, it is a very short run and the VW TDI turbo drain hose I hacked up (used part I had) looks like it will work ok, red hose is Gates multi-use hose. I use it for transmission line and fuel line in some applications. It should take the heat and petroleum product hopefully. This turbo should pass a small oil amount compared to a larger unit. Not too worried about the heat in the valve cover or oil drain there is plenty of windage space for the oil drain, also a nicely engineered baffle under the valve cover.
Sorry if I didn't answer any pertinent questions, busy day yesterday then company arrived and out came the beer. 10 inches snow here this morning looks like the hand shovel comes out
Fred, back on this today hoping to get a test run out of it with a temporary straight pipe until I find a nicely built short and 304 stainless glasspack so I can fab a sweet little quiet exhaust package. While I liked much noise in my younger days quiet is much nicer nowadays. Every now and again at work a Harley will drive by with bone stock pipes and sounds oh so sweet, usually driven by women.
