If you get 60lb your tuner will tune them for whatever fuel psi is needed. There are a couple of guys on here selling new 42lb injectors. dbthor14 10-27-2008, 10:53 PM there is a forsale post with 50lb injectors. so you think that would be good for my set up? thisdude_05 10-27-2008, 10:56 PM Yep. I have a regular ZX3 with a procharger on 10psi and I'm using the 60lb injectors but they are tuned for 42lb. toeycrack 10-27-2008, 11:13 PM i got 42 for sale, ill sell em to you guys for 130, on the bst fourms there listed at 150, mine is ford racing brand. pbeam27 10-27-2008, 11:53 PM i thought that you can have the stock injectors with a boost a pump BMARTIN03ZX3 10-28-2008, 12:47 AM i thought that you can have the stock injectors with a boost a pump The injectors won't be able to flow the amount of fuel needed and they will max out easily. Look up some of Toms post about injector sizing. thisdude_05 10-28-2008, 12:52 AM Yeah the boost a pump is exactly what it says....boost A PUMP. Your fuel pump. All that will do is increase the voltage on your fuel pump to pump more fuel but if you don't have big enough injectors for the amount of fuel the boost a pump and fuel pump are pushing, then there's no point. Gotta get bigger injectors. dbthor14 10-28-2008, 01:21 AM i dont have to buy a bap do i? i only need that if i want to go more whp or boost. thisdude_05 10-28-2008, 01:32 AM i dont have to buy a bap do i? i only need that if i want to go more whp or boost. No you can use your stock fuel pump alone. Stock fuel pump will hold 300whp or more. Ask 03OrangeSVT. He's using the whole stock fuel system (minus injectors) and he's making well over 300 hp. BOOSTA 10-28-2008, 03:09 AM how much hp can a duratec fuel pump hold, the same? thisdude_05 10-28-2008, 03:16 AM I would imagine so....I know the 03-04 fuel pump flows alot better than the earlier years so yeah I would think so. focusguy87 10-28-2008, 07:24 AM No you can use your stock fuel pump alone. Stock fuel pump will hold 300whp or more. Ask 03OrangeSVT. He's using the whole stock fuel system (minus injectors) and he's making well over 300 hp. Wrong he has a BAP..... focusguy87 10-28-2008, 07:27 AM I have some #38's that would work. $60 shipped thisdude_05 10-30-2008, 02:33 AM Wrong he has a BAP..... Oh ok my bad. Must have read wrong somewhere. focusguy87 10-30-2008, 06:47 AM Oh ok my bad. Must have read wrong somewhere. But your not wrong about the stock fuel system making 300whp. With the right injectors, and right tuner. The tune can increase fuel PSI that is able to safely make 300whp with, I'd say #60 injectors | |
