A little more detail on the home DIY turbo tractor project.
This is a Jinma 254 tractor that was a little under powered for the size of some of the implements. So we welded up a turbo manifold, and intake. Bolted up a turbo, and cranked up the fuel. The tractor is much more powerful now, never overheats anymore. It will plow right through brush and the rotary cutter won't bog the engine even in the heaviest brush.
