Thanks for all the comments
#2 looks messy because the wiring harness for the coils and variable exhaust valves actuators is out of place and looks disheveled, I did a image/adjustment/shadows and highlights in PS, it exaggerates the dirt and makes it very visible
the new turbo is in #4 top of the image in the center, to the right the intake side can be seen in a shiny silver tone with a red tab sticking out, the intake pipe is still uninstalled
Insurance will cover the new upgraded parts if reported, if not reported they will pay for the original parts
My friend consider his cars as toys but drives them very little, the car is a year old and has only 5000kms , with the modifications his warranty is no longer valid but he does not care, also he does not race the cars and drives responsibly, he simply enjoys having a very powerful car.
I helped them because I enjoy car mechanics, and good company, no wifes, girlfriends, or kids, just 3 guys tinkering with a car, a perfect Saturday
