The F10 M5 is running extra boost but is built from the factory with the engine internals and cooling to accomodate that boost. This upgraded design and build should make the M5 reliable with the extra boost.
The N20 is intended for a totally different market. It will therefore be built with less expensive and less capable engine internals and cooling system that meet the design specs. The engine will still be high quality, just not as high quality (or as expensive) as that from the M5.
The point here is that both should be reliable in terms of what they have been designed for. The key point is just that - the design specification. Its not just about the boost you run.
Moving the N20 to much higher boost moves the power output of that engine outside of the design specifcation. Such an increase requires upgrading other effected parts in order to maintain factory reliability specs.
