Escort Cosworth uprated fuel pump

[MONTE 005]

does anyone know if a bosch 0 580 254 003 fuel pump is good for an escort cosworth
running about 350 to 450 bhp?

[Bosch Man]

no you need the 023 (identical to the 003 but higher flow) from me £100 all in delivered

003 good for around 350bhp.

Whats the best pump for a small turbo. Car is only standard, but i've read that the pumps are marginal even on standard cars?

You don't want the standard pump on Stage 1 or above as my mate found out to his cost, he melted a spark plug & an exhaust valve on his Stage 3 setup, he also manged to weld part of one of those items to the top of the piston for good measure.

I'm going for a Walbo pump in my ST but I'm only aiming for 350BHP.

Mines standard and staying that way (even though Mike R thinks its ) so will the standard pump be ok?

Only way to be

It must be good enough as they wouldn't have used them otherwise, mine is on a standard pump and runs perfectly and was spot on fuelling wise on the rolling road day last year

[Simon T]

Is yours standard then Ben?

The standard pump came from a 1.6 escort & they're tiny (the pump not the car).

Its funny that most parts on a Cossie are over kill yet the fuel pump is one of the most critical parts in the fuel system & just about up to the job.

near enough matey, just a stainless with motorsport cat and K&N was running well at 254bhp last time and that was with a little niggle with the wastegate, which should have been sorted now

I would replace it with a Walbro pump, plenty for standard power and should be direct replacement I think.

Sounds the same as spec as mine, mines done 240ish a few times.

that sounds like your answer, must admit if I had the tank off it would be rude not to change it
