s400 make over 1k hp i have not seen it i have seen 480 in a twin setup make 800hp. but then again im not a turbo master. if you were to get anywhere near that number you would need to wastegate it so you could run off the bigger turbo as the stocker would kill your airflow. if im wrong please jump in guys like said above im not a turbo master just seen a few setups run.

Yes....several people have ran a stocker/S475 kit. Your 04.5 should have the bigger and better HE351 on it now. The setup should do fine, although if you ran it with a 62mm instead of your stocker, it would be much better.

will work great and i know people running this turbo with over 1000 hp but thats on cars ! when people says it is capable of 1000hp does not mean anything IMO you can have a 1000hp engine had any turbo and say it can hold a 1000ho

I guess it depends how much power you want to make using your stock turbo in the compound setup :confused: The stock turbo with the 9 turbine housing is really the downfall of the stocker compound setup. You can probably make about 700rwhp with drive pressures being a slight issue. I threw down 676 with the stocker/a5k setup. You would be much happier with a 62/65/12, 62/71/12
