Does anyone make an upgraded fuel rail for the contour zetec?

I am putting a 98 zetec out of a ZX2 into a 93 escort wagon. I need to use a 95 contour FR to do this because the ZX2 rail is returnless but the contour rail is a return type which is what the escort has. I have a stock one already.

My HP plans are 350HP. I have purchased the following already to reach this goal
FR head, WEBCAM HI torque cams, Walpro FP, turbo header, t3/t4 turbo.

Does anyone know what the stock rail will support?

Thanks for the help
John
 
Steeda makes one for the Focus, but I believe its more for looks than performance.

There are Foci(plural for Focus) running over 300FWHP on the stock rail. So, as long as you upgrade the fuel pump and injectors and get it tuned, you should be ok.
 
I was goign to say I have never heard of anyone upgrading the fuel rail on a zetec or a duratec when they have upped the power ... injectors and tuning yes ...
 
the fuel rail will be fine just dont run anything over 60PSI for your fuel pressure. i would try to size everything and have it tuned for around 45PSI
 
I have a friend with a tuned focus and he runs 75 psi on his stock fuel rail the only thing he had to do was replace the rubber hoses that connect to the fuel rail to fuel filter/fuel filter to hard line and return rubber lines with st/less steel braided fuel lines. he got them from a focus tuner web site, but I can't remember which one. I can ask him and see where but I'd have to wait until he gets back from his deployment in the desert. It should work on the 98+ zetecs I'd imagine.
 
Its not recommended to go over 60PSI on a stock fuel rail. some rails may be able to handle it but most of them cannot.
 
i was just talking about in general, as in all cars not just the zetec/contour as i have also seen zetec foci that are running over 60PSI without problems. but as a general rule if you have to run that high of a fuel pressure you need bigger injectors. its much safer that way.
