I disagree ECU-MAN, a stock Fuel pump from an NA car is not sufficient after a turbo conversion. You will definitely need a bigger fuel pump if you are going to run bigger injectors and re-tuning your fuel map. the pressure and flow from the stock NA fuel pump is not sufficient, even if you add an adjustable fuel regulator.
The best way to check will be to connect a fuel pressure gauge to your fuel system when tuning your car on a dyno after a turbo conversion, you will see that the fuel pressure will drop as more fuel is being pumped into the engine , even with a regulator. the stock pump is not able to maintain an ideal/safe pressure level.
I know this from experience. ;)
i agree with ECU-MAN, cos i run a stock pump with boost and it copes fine
Iv seen Stock fuel pump handle 440cc injectors quite nicly, maybee with larger injectors, then yes, But I do know that the stock pump will do the job on certant turbo set-ups
Oh well, I must be wrong. :o I guess it depends on the type of car you have. Mine is a D16Y4.
Have you guys tried checking your fuel pressure during dyno runs?
i guess it depends on alot of factors when going NA or FI.
i just remembered that the ITR-turbo is stock apart from using methanol injection.
but my car had to get the fuel pump upgraded (mainly cause of carby to EFI upgrade)
no ones wrong!
