I just bought a 2007 5.9. It has an aurora turbo already installed im trying to find out what size it is bit it spools very slow so i think it is a 5000. If thats the case i would like to twin turbo it with a he351. Is there a piping kit avalable for a reasionable price? Thanks

 

Here is a link the Aurora 5000 turbo,

ATS | Aurora 5000 Turbo Kit for Common Rail Dodge, 2003-2007 5.9L

ATS should be able to make/have just the piping kit to make the stock turbo and the Aurora 5000 work together.
