nitrous fuel pressure

i am going to put a 125 shot on my 4.6. i have forged pistons and rods, and a girtle for the bottom so i am not worried too much about blowing out the bottom of it provided i tune the pms right. i was wondering of a good injector size and fuel pump to go with. I think a walboro 255 should do it or i have heard that the focus`s have high flow pumps. In other word i just want to make sure i can get the right amount of fuel for the spray. Anyone got any advice?

I was thinking along the same lines. I will probably go with the focus pump. I will probaly go with a wet kit. I have a 2000 GT. I have forged JE pistons with 10 to 1 comp. Eagle H beams. I have yet to get it by I am going to order a 4.6 girtle from a local shop where I am stationed called fastlane. I have VT 2 NA cams with crower Springs and retainers. I will probably buy the ZEX wet kit. I just got my Anderson Ford Motorsports PMS in the mail a little while back so i will use that for tuning. With a 125 shot I am hoping to put down over 400 HP to the wheels. Maybe more with a good tune. With 3.73`s on slicks i would like to hit low 12`s high 11`s. Does that sound like an attainable goal?

I still have my work cut out for me though!
