I know the head unit is missing ( it was procharged at one time ) it still has the piping an the inter cooler in it and its all hooked up, no shop will put another head unit in with out knowing exactly what's missing, the closest shop to me that sells them is 5 hours away and I'd hate to drive that far for someone to tell me. This is the first car I've ever owned with a procharger.. If you need more pictures let me know thanks in advance.
