Injectors
Anything over 330cc/min and ford fitment preferred.

Erm Pass, Its for a duratec fuel rail, which hopefully would fit?

I've been reading about a Zetec going into a Cortina, the bloke is using an ST170 inlet/fuel rail.
He points out that the injectors he needs (RSTurbo ones) are expensive, so bought some BMW mini Cooper ones from ebay for £13.
The only thing is, they're 13mm shorter than standard, so he had his fuel rail altered. He had the 2 "posts" that mount the rail,
shortened by 13mm and ended up with some dirt cheap, but brand new injectors.
Dunno if it helps, but I was impressed with the lateral thinking and the price ! 
The post is near the bottom on THIS page.

That sounds like the git that sniped the Cooper injectors I was bidding on a few weeks back  I knew I should have put a higher bid on
to secure it!!! LOL!

Big horses....330 seem big unless you are going for 260+ BHP.

Sounds about right.....
I'm looking at 4* 288cc/min injectors for 160Bhp. My BSFC is a bit higher as I'm going for supercharging....

I run Vx 212cc bosch injectors, good for 190-200bhp. Go too big and low down response can suffer.

bosch cremes off a vauxhall 2ltr (astra gte, cavalier gsi, calibra 16v etc) should do most things upto 210bhp.
check the impedence that your ecu requires them to operate at aswell.

so why does the calculator come back at 300 off cc/min if 212 will cope with 200bhp?

Dunno, all the calculators i've seen tend to oversize by a fair bit. I took one as gospel once and sourced myself some ~325cc/min sierra cossie
injectors for a vw 2.0 16v, they never ran over about 65% duty cycle. Could just be the 'internet idiot factor', telling you a mahoosive
figure so you don't end up going borderline small and blowing things up. If you plug in the figures for most OEM setups the calculator will tell
you the standard injectors are undersized...
If you do want 330cc/min or thereabouts cossie ones come up cheap on ebay all the time

mhhh i would play with the fuel pressure
it automaticly ups the flow/delivery of an injector..
Tks

I am using 270lb injectors giving around 165-170 bhp and am getting nowhere near the max duty cycle. As said, don't go too big or you will
struggle to get a good idle.

I've wondered this for a long time but never really found a good answer. If you plug the Vauxhall injector numbers into one of the injector
calculators they appear to be barely adequate for the stock engine at 100% duty cycles. Obviously they work fine, so something is amiss.
One thing to take into account is that the fuel pressure needs to be increased to reach 200bhp with the Vauxhall injectors (2.5 to 3.5 bar), but this
only takes the flow up to about 250cc/min IIRC.

As Ned said, vauxhall cream injectors are fine for up to 220hp at sensible pressures.
My 3 engines run on them never complained and all made 200+ hp.
Look around and oyu'll find a set for the price of a beer or two.
(If I can be arsed I'll have a look and see if I have a spare set tomorrow, beer bribes accepted)
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

For 200bhp I would guess the standard Duratec ones will be fine. At worst I guess you may need to up the fuel pressure slightly.
