turbo AR

So you ended up going the s475? What flange and a/r? It'll really make it get up and go..

Regarding fuel return, if going blow through you will need 1/2" minimum or you won't be able to get the pressure low enough, speaking from experience.

I've had some experience with the 6530.. Shoot me some questions if you get stuck

Awesome work.. Mine has gone a different direction, turbos are the flavour of the month :)

when you say 1/2" min return or won't get fuel pressure low enough, I get that the smaller return will be the restriction, but what pressure should it be.
