Think I may need to replace my fuel pump so can I put the cossie pump in with my standard injectors and 165 superchip??

Or do I need to go to the 195 chip with the biege injectors??

How much will it cost for the chip, injectors and fuel pump??

Thanks
Joe

Doesn't matter what u run ur fuel pump with as long as the fuel pressure is the same. Adjusted by a screw/dial on the fuel rail me thinks.

I run an Escort Cossie pump with 195 chip but still with original injectors at the mo so running at 10psi.

If u can afford it get 701 injectors, the uprated pump and a Bayjoo chip.

[BUTRE]

what fuel pressure at the rail must the "stage 195" have? and up to can the std fuel pump and a FSE on the rail go?

Hello.........

J Brown.......put inthe cossie pump, it wont matter as it's a pump and thats it. Just make sure to get your car set-up after to make sure the fuelling is correct. You wont need injectors or another chip. You will only need a new chip and injectors if your planning on increasing boost and your std injectors cant cope.

Butre.......every car is different, get your fuelling checked on a rolling road as the car is running under load, thats when u should set your fuel pressure. Do NOT use a FSE valve, your FRST already has an adjustable fuel pressure regulator. Save your money and buy something that will actually help

[BUTRE]

Fezzy Turbo, what??? I'm lost here. Just want to know what fuel pressure at the rail must I have to cope with the 195 chip.
I know that std injectors are not up to the job... Just want to understand why must go to cossie pump.

The std FRST fuel pressure regulator is adjustable?? how? squizing it and by so it squizs the spring inside? this is no where near a adjustable item.

[MIK3Y]

There is a screw on the fuel rail which adjusts fuel pressure so no need to buy a FSE power boost valve, although if running over 10psi an uprated (escort cossie) fuel pump is recommended to supply the injectors with the juice as quickly as it is required.
Standard injectors r good to around 15, id stay safe & run no more than 13ish though. However u will need a chip to make sure the petrol is being supplied properly at any boost level over standard.
Make sense?
I don't know much but if u read up on the basics it will explain it in detail 4 u.

[Fezzy Turbo]

Butre.....
To just set the fuel pressure on the rail and then run your car is not very good (to be polite). It's not the chip the fuelling has to cope with, it's the amount of air entering your engines cylinders. Do you know what boost u will be running ? do you know how efficent your Intercooler is ? all this adds up to setting up your fuelling. If your fitting a 195chip, take it along to a tuner who will fit it and set-up the fuelling for the car as it runs at full boost. As you or the tuner wont know what your car will be like until tested.

Safer in the long run.

There is an adjustable fuel regulator at right hand side of the fuel rail (at the end). There should be a wee silver top on it, that is a nightmare to remove. In there there is an Allen key which can then be turned to adjust the fuel pressure.

Im running 15psi on std injectors and std fuel pump on a 165chip and NO FSE valve.

[MIK3Y]

Will i be able to do that even though i hav a T3?
Ive got a 195 chip, will set my new actuator to 10psi but will hav an in-car boost valve to run upto 15 if this is safe?
I hav an uprated fuel pump & head gasket so should be alright shoudn't it?

[BUTRE]

ok... I'm doing this myself because there isnt a single tunner here that can do it on the rolling road. this is why I love this country.. what can I say.

I'm looking on going on a 195chip with 16PSI of boost.

I think the std IC only can cold down to 12PSI. So it needs to be changed.

ohhh the std regulator can be adjusted.
If I need to use a cossie pump, than adjusting the std regulator DOES make sense now.

I'm new to the FRST engine... take it gentle

I was looking to have some number here: like 3.5bar on rail with beije injectors and 15psi of boost.... that kind of numbers.

[MIK3Y]

Well the Superchip is an off-the self chip anyway so u could run it with-out having it properly set-up (mapped). Just be aware off it's limits such as psi limit of 15 on a 165 chip (i think).
There will defo be a garage with an exhaust gas anayliser which can make sure that ur fueling is spot on at idle. Any engine re-builder should hav 1 to set-up the idle fueling by adjusting fuel pressure to make sure the cylinders r getting the correct mixture (which is what the gas analyser will tell the mechanic).
Get this done when u fit the uprated fuel pump and chip m8.
Any1 feel free to correct me on any point.

[Fezzy Turbo]

It all very well getting set for idle, but your main worry is getting it set when the car is under maximum boost. This is where trouble will start if not setup correctly.

MIK3Y.....
I wouldnt even go near an in car boost adjuster.

Why u running a 195chip if all your wanting is 15psi ?? a 165 chip will cope with that, it does on mine.
Just because u have an uprated fuel pump and new headgasket, that doesnt mean ur engine will be problem free.

BUTRE....
yeah the std I/C aint much good after 12psi.................that reminds me..........i really need to get rid of mine

[BUTRE]

hum...

gas analyser... wide-range lambda reader yes. CO analyser no, its to slow to be accurate.

Fezzy Turbo is right. At maximum boost is the thing to look at when it comes to air/fuel ratio.

Its this kind of info that lacks on the web.

what you need to get 190/200bhp on a std FRST?? eheh this is what I want to know.

- std gearbox can handle it. (at least Ian Howel has used a std gearbox on a too much tweaked frst).
- When it is needed to change the pistons to forged ones?? And I'm NOT going to low the CR!!!!!!!!! too slow when off boost.
- Dont want only power at peak... I hate the burst of power only on a 1000rpm band. Need power to pull from 3000rpm to 7000rpm.

any wise ideas?

[MIK3Y]

Nothing wrong with in-car boost if u can restrain urself IMO.

195 chip came with car.

BUTRE: I know that running over 18psi on standard compression engine is REALLY pushing it m8, so i think that low comp pistons r a must for a 200+ BHP goal IMO.

[snake]

last check mine was 196 bhp, revs to 8200rpm ish, kent 35k cam, standard pistons , stage 3 t3, runnin at 0.9 bar to acheive this, goin upto 205-210 bhp when its back on the road , lol obviously not the full picture, but yes its acheiveable with the rite mods, driveabilty is v.good..

[snake]

oh i run 45-50psi at the rail i think, and on 701`s and stan coss pump theirs plenty of fuel!, lol nearly stalled the thing when we put it to max fueling to check it

[MIK3Y]

WOW 8200 revs. Now u need a lightened & balanced crank to do that though, so in terms of money 4 power, it is probably cheaper to hav low comp pistons fitted but i bet it flies!

196BHP @ under 1bar! MINT!

Mine should be similar with 701s only can only go to 6500 revs.

I take it the extra revs require extra fueling else the stanadard blue injectors would manage the boost ur running.
Do u not need a special chip to manage the extra revvage? Thanx

lightened only, light skim on flywheel only to take paddle clutch, low comp is trade off for driveability low down, i aint used low comp and don`t need em for bhp i want, rods will prob bend first, lol. no power up their btw, we just wanted to see wot it could rev to lol, extra revs do require extra fuel, but 701`s were not fitted at time i got the map checked and i had a 5000 rpm limiter put in at 190 bhp, their was no fuel at the top end, so blues are only good for 175-180 bhp max! i run unichip at the mo..

[snake]

oh and torque was pants with the blues as it didn`t have enough fuel goin in when the turbo kicked in lol, and amount of mods i`ve done to that engine is high, gonna take it to its limit on these rods, then leave it, for now , don`t expect 200bhp without major mods and intake cooling to go with it

[BUTRE]

Snake, you are going the route I want to go.

Low compression pistons will KILL power at low rpms... I would trade 10bhp of peak for muscle on low and middle rpm any time.

now injectors
FRST comes with "blues" injectors right? what injectors are they?? Part-number.

"Beije" ones are the bosch 701's?
what about bosch 803?

Bosch 0 280 150 803 injectors flow 390cc per minute on 39.2PSI (2.7bar).
We can estimate the flow of:
- 411cc per minute at 3bar
- 438cc per minute at 3.4bar

This numbers are almost acurate.

803`s are cossies and not direct replacement, diff ohm ratin, they are overkill and not required, can`t remember blue numbers got em somewhere but moved so all paperwork is scattered at the mo, lol.. i would go for 701`s although 803`s are cheaper and u can fit em with a mod, well think 803`s are standard coss items, soo many numbers off top of my head can`t remember them all

[BUTRE]

Correct me if I'm wrong:
803 injectors will not go with std ecu. They are 4.8ohms while std injectors (and 701) are 16ohms.

I need the part-numbers so I can start looking for them on scrapyards.

[snake]

701`s are fitted to m3 beamers, don`t think their is any other car which has same ish fuel rate as them, 803`s yes diff ohms.......... 2 catagories, high ohm, low ohm, think anything above 11/12ohm is fine and anything below 9ohm is considered low, nowt inbetween really..

[BUTRE]

I've got that pdf adrian, but the problem is that ppl usually call the injectors by the color and not by their manufacteur part-number.
