A lot of it was stupid stuff like the catch can and some of the intercooler piping needing to be hard mounted. Drive shaft loops. Intercooler was a bit too big for the crash bar to not be modified so had to trim down the cooler a bit, iirc it was 2 rows and modified the routing on the pipes a bit but had to remove my dogs because of it. Since the car was registered after may 2010, by like 3 months, I had to get a catalytic converter put in. Thankfully the turbo, wastegate, injectors, etc all passed without an issue. Nothing on the interior. My cusco engine and trans mounts weren’t showing enough threads after being installed but thankfully we just had to tighten them up even further. Last thing I remember was some additional heat shielding, but not much.
