   What makes have you been looking at?
   
   
   
   Weber Alpha do a nice unit.... and although FSE have a bad reputation for "normally tuned" cars, they are actually quite good for highly tuned applications.
   
   
   
   FSE valves offer feck all performance gain on a normal saxo, as the lambda system will see an increase in fuel, and remove it.
   
   
   
   I've been using an FSE fuel pressure regulator for anout 6 months now with no problems... Cost about £70.
   
   
   
   Not sure what prices you've been looking at?

   You could always buy a fixed rate regulator... fixed at a higher pressure. Direct replacement...
   
   
   
   This would be a standard fitment into the fuel rail/tank dependant on model. You wouldn;t have to mess about re-plumbing fuel lines this way either.

   Uprating the fuel pressure alone, would NOT be sufficient to run your car in a boosted state.
   
   
   
   However, if you do want to build the conversion now, anf set the fuelling up later (not too later) the car will be perfectly driveable...
   
   
   
   ...Provided you don't accelerate hard! The harder you accelerate the more boost is generated, which will lead to pinking and piston failure without the correct amount of fuel.
   
   
   
   If you accelerate casually you will not build any boost. It weould be no problem to accelerate from 0-70mph slowly and never actually build any positive boost pressure.
   
   
   
   Hope this helps.

   Also which one would be better to use a FSE one or a GMC one

    GMC one probably.... depending on type.
    
    
    
    FSE is fine in my opinion though.... depends if GMC is rising rate or not?
    
    
    
    I wouldnt bothe ruprating injectors i dont hink.. unless you are doing it as a temporary basis until you can get it mappe up with some additional injectors.

    I have spoke to mike at Qforce and he said it should be ok running the GMC one and uprated injectors for short term to run 2-3psi of boost until get mapping sorted

    I could be wrong,but I thought the GMC ones were fixed rate 4/4.5 bar ones. The FSE might be more suitable,would save having to change the FPR later on again.
    
    
    
    By the way,the 4 bar ones you can get very cheaply **cough cough nicked ahem** off a V5 Audi/VW at any local scrappy <img src= "smileys/wink.gif">

    They sell fixed rate and Weber riaing rate ones. Not sure which we're on about here though?
    
    
    
    Fixed are more stable... adjustable are more flexible..
    
    
    
    Depends what your after I suppose?

    yes and they even do a real rising rate reg one from2bar to 7bar ,but unless you gonna fit a very big and expensive pump,plus redo all the fuel piping .its not the real answer. for low boost application it will be ok providing you disconnect lambda some how.you can change the settings so it doesn,t go that high ,but anything over 4.8 bar will drop fuel supply volume too much ( GMC is me by the way)
