Wow this is an old thread! lol Does anyone happen to know what an Aurora 4000 is based on? The 5000 is k31 based, the 3000 is s300 based ( i believe), what about the 4000?
I think they make a 6000 now?
anyone know the k31 part numbers ? i'd like to send mine to be rebuilt but don't feel like sending it to ats
what are the specs on the 7000 i have seen it in there advertisments in diesel power magazine. it is the bottom for one of there twin turbo kits i think.
