Took the car to the rolling road only to be told "we wont do it becoz it has a fuelling prob"
Apparantly the t3 converted chipped up fiesta of mine on the standard fuel pump doesnt supply enuff fuel/pressure and can cause detonation?
Is this tru do i really need a escort cossie pump or an upgraded one to save my car?

 

cossie one will do fine

 

What injectors are you using and what Psi are you running? If you got beige injectors then a Escort Cossie one will be a good idea.

But a fueling problem doesn't mean it's the fuel pump, other factors to consider

 

im running a bar of boost and normal injectors i think, the rolling rd guys told me theres a fuelling prob and getting a cossie pump or uprated pump is what i need

 

Standard injectors and 1bar boost will be the problem mate. Those injectors are no use at all at that boost pressure. 12psi tops iirc for FRST blues.

Cossie pump isn't essential with 195 but it is advisable. I'm running mine on th estock pump with beiges, 195 and T3 but the car isn't used very often and a pump is on the shopping list

 

yeh i spose u cud be right i get a massive boost at 15psi then it drops off slightly, but if i got beiges and got them put in it wud mena another visit to the rolling road centre and its 150 quid a visit !! wouldnt it?

 

roughly how much are cossie pumps?
as its next on my to get list

 

I went for an uprated fiesta pump coz its a straight swap and handles up to 300 bhp it was 100 with postage
the cossie ones are about the same give or take a fiver but its from the shop on ebay and hey are brand new
u can find second hand ones but if they fail its a big problem so I recommend new ones here save yourself a lot of problems.

044 pump. It's exactly the same part number be it classed as Escort Cossie or FRST upgrade pump.

 

you will need an escort cozzy pump and some bigger injectors to let more fuel in either beige injectors or greens a good tuner will advise you ,give pj motorsport a ring they are helpful

 

Im not sure about this one because i communicated with the seller he has a whole shop of pumps including the cossie one he said "i have 1 fiesta upgrade pump left" and I bought it

 

100% correct

Can't use greens on the FRST, next step up from beige would be something like Audi 2.2.

Anyway, where in sunny North Wales are you??

 

im in conwy.my mate has just put greens on his with a live mapped chip and a hybrid

 

I hope he's changed over to cossie managment/aftermarket ecu otherwise he's going to start fring ecu's. The cossie green's are low impedance. A chip wont do

 

greens wud be too much for a fiess they are an cosworth upgrade LOL different ball game unless u have a bottomless wallet

 

Injectors are a bit more complicated on the Fiesta as without a suitable chip to run them they are next to worthless. Beiges fuel to about 225bhp before you need to worry.

 

i double checked the colour of the injectors and they are light green,hes also got a 3 bar map sensor of a cossie.hes had the chip written for him to go with a cam and a t3 but hes limited the boost to 12 psi untill he gets a big intercooler

 

yeah im limited to 12psi as well not just coz of the pump but i darnt risk it on a standard cooler it wud just end in tears

 

I'd be asking who wrote the chip program and cost if I were you as it sounds like a bit of Billy Bullshit

 

does adding beige injectors really make a noticeable difference? i just received the upgrade fuel pump aint got round to fitting it yet any1 know if i will notice the difference., t3 and chip

 

wanna upgrade me fuel pump as well..can i use the upgraded cossie/fiesta turbo one?am running a 2l zetec on gsxr tbs.

am using st170 injectors?do i need to change em?

thanx

 

escort cossie pump is a straight swap or go for the uprated fiesta 1 to be sure

 

Will you notice the difference with beige's, chip and a T3? er........ Yes! that should have you knocking on the door of about 180bhp

 

i got power runs wen the t2 turbo was in it hit 184bhp then! at 16psi
