Look like a nice setup. All that cutting makes me nervous, probably for no reason. Nice work.

Wishing you all the best with your setup. Like others commenting I cannot see sacrificing structural integrity for bit more HP.

Have you noticed any drop in boost/responsiveness with this setup? I considered a front mount. Our cars are notoriously has high intake temps due to the top mount

That is just obnoxious. Why would you even bother doing it?

If I had to pay that type of money to have an Airtrech intercooler mounted on my r53 and have to butcher my car like yours.... hell fucking no I would never , I would send back the parts to that stupid company and tell them to shove it where the sun don’t shine. Crazy stupid company I swear and the people who spend the money for that intercooler 🤣🤣🤣🤣🤣🤣🤣🤣
