(sorry long weekend) The issue becomes when opening sourcing engine components it becomes very easy to damage engines in ways that could injure the driver/other people on the road, as well as maintain EPA standards for emission and fuel consumption. Not every mechanic is a Fuel System Engineer, its relatively easy to hydrolock an engine. If you screw up the internal mechanics then just a hop-skip-and-a-jump to a VERY rapid dis-assembly. It's a lot like overclocking, but instead of a 500CPU you have a 5,000 6 chamber bomb.
