Icon6 Fuel need for 450ish HP

Doing a vitara build on a z6, holset hx35 which I believe flows about 63 lb/min... What doni need as far as fuel goes... I'm getting the standard walbro 255, a fuel rail, probably the blox fpr ( not sure if it's blox...it's the one that attatches to the top of your stock fpr) but...
What size injectors do I need?
What type? peak and hold or saturated?- I know I can find it but thought I'd throw it in
do I need bigger lines all the way from the pump or will the stock ones work?
Can I use the stock fuel filter?

Any other advice is greatly appreciated..

I would like to be able to handle 500 so that I have plenty of room to play with

I know the difference between saturated and peak and hold but are there advantages
to either?
And so I can run 1000cc injectors on stock lines and filter?

If you're running gasoline, you could get away with 1000cc injectors, but if you have access to E85, you'll need something larger. The Walbro will do, but you dont need to upgrade the fuel rail. The stock rail should flow more than enough for your needs.
