Most of it comes from the 30% tax on imported goods that was put into place not long after the president was elected. (but there not taxing the little guy). Kinda leaves no choice but to look at building here. The motor itself is not the complex part of the machine. With the right tools I could build the same thing with a engineer and a cnc machine. Its the computer and mapping that gets the most attention, (because of emissions) it can cause all kinds of problems. most everything else is already being built by After market companies that do it better anyway. I think the most important thing is having a high standard of quality to make sure the engine is put together perfectly with high quality metals and parts.
The engine is one of the places you don't cut corners like the cheap DD bearings. They will also have to maintain there warranty.
