I was wondering if anyone can help me with this. I currently have the stock injectors that came with my car, and I was wondering if I went ahead and upgraded to a 440 injector with a fuel pressure regulator in front of it, what would be the consequences or benefits.

I will be adding a turbo with about 6 pounds of boost, but for now, just the current list of mods.

If you do ever go forward and want to purchase those, let me know, i know a good hook up for those. The whole fuel pressure regulator thing is that you cand adjust the amount of fuel going into the air fuel mixture. The thing about that is, once you add it, you might want to get a gauge and set it up.

 

Upgrading injectors and FPR would be bad for your car since you are now running VERY rich....I wouldn't add these injectors until you have a need for it (FI). Also if you're going boost why not run a standalone ecu instead of messing with a FMU (which is what it sounds like what you're planning on doing)?

 

If you really want to run those inj. you'll need something to control them. LIke a s-afc or v-afc hack. These will trim the inj. out other wise there will be to much fuel for the car to even idle.

 

if you do put on these injectors, put on a supported computer for tuning and if I understand what you want to do correctly, you can just lower the duty cycle on them.
