Looks very very good! The roof might actually be a mild steel "cover" like it is on the Edge, where it can be removed and replaced.
Can you see the intercooler if you shine a light through the condensor? Maybe LED lighting instead of stenciling? bpd has done a lot of work in the engine bay with lighting, so likely would be able to provide guidance.
I don't see a crank or cam sensor causing a misfire. No fire, maybe, but usually a trouble code will set or the PCM will initiate lower power routines to compensate. Of course, codes are set after a threshhold is met, and if the sensor is weak but not weak enough, the PCM would keep doing what...
