i have some question, if i run turbo!

  1. if i run turbo w/ the 450cc dsm injectors, will i still need the fmu?
  2. whats the difference between a fmu and a fuel pressure regulator, if i use a fuel pressure regulator, will i still need the fmu?
    3.can i run without my fans on my radiator because ive seen g2integra turbos w/out the radiator cooling fan?

im pretty sure someone knows these answers so itll be kool if you guys anser and give me some tips on this so i can complete my set up…thanx…

1/ 450s with what controlling them, the AFC hack will be fine.

2/Diff betweeten an fmu and fuel Pressure Reg is that the fmu increases fuel pressure when it senses boost the the Re just increases fuel pressure fullstop or period as you yanks say:)

3Don’t be a dumbass the answer is NO:idea: :drive:

just thought I would add that turbo’s make a lot of heat, you want extra cooling, not less…

  1. no

  2. FMU refers to Vortecs Fuel Management Unit, it is a rising rate fuel pressure regulator…as boost increases the FMU increase fuel pressure to compensate for the extra air. The come in several different ratios, 12:1 and 10:1 are the most common…this means that for every 1psi of boost the FMU adds 12 or 10 psi of fuel pressure.

A fuel pressure regulator is just a normal regulator that keeps fuel pressure at a steady level accross the RPM band

Yes you will need a FMU and a fuel pressure regulator, the stock fuel pressure regulator will do fine, if you decide to go with the FMU and Missing Link engine managment set up.

  1. I can’t imagine anyone not running any radiator fans. What would happen when you’re in traffic and there is no air going through the radiator? It would overheat in a heart beat.

I’m a nut about cooling…I did a lot of extra work to keep things cool. A lot of turbo Honda engine failures come from a lack of cooling. So don’t skimp on the cooling…if you do…don’t bitch about your blown motor…

good luck

you say no to number 1 question which i ask if i need the fmu if i run on dsm 450cc injectors, then you later said i will need the fmu? correct me on this!

I miss read…when I saw 450 DSM injecotrs I thought you would be using the AFC hack…if you use 450cc injectors with out the AFC hack you will need an FMU and missing link…but you are going to have A LOT of trouble getting those huge injectors to idle using an AFC, FMU, and Missing link set up.

If you’re going to use 450cc injecotrs you should use the AFC hack method or a stand alone ECU, in which case you will not need a FMU or missing link…

thanx for the tip, so basically, if i use the 450cc, i wont need the fmu, is it possible to just run the 450cc without the fmu and afc hack and instead use a turbo rom ecu chip? just wondering.

no…it depends on what you use for engine management…let me try to make it clearer, here are your options:

450cc injectors, FMU, Missing Link, and AFC normally operating (this is going to be hard to make run well becuase the injectors arer so large, this also results in high fuel pressures so you may need a high pressure fuel pump depending on how much boost you run)

450cc injectors, AFC Hack (you may need a high flow (different from high pressure) fuel pump depending on amount of boost)

450cc injectors, stand alone ECU (Zdyne or Hondata, you may need a high flow fuel pump depending on amount of boost
