I've purchased some as I was unaware of anybody distributing from here, the ones I have bought are here and do state 80lb versions
http://www.ebay.co.uk/itm/221167070856
They will be going in my zetec turbo and currently on a t34.63 though I will be upgrading to a gt30
After liking about seemed the 630cc ones would be that bit small unless we could crank the fuel pressure up
Many thanks for the replies

Having a scout about the cosworths run low impedence which seems that is mainly what the 83lb versions are and the 80lbs are high impedence, I'm currently using Dta s40 ecu which uses the high impedence injectors,
So no real bad reports then which is good
Many thanks for the replies guys

they do respond well to raised pressure to act upto 900cc, the problem is getting a fuel pump to provide 6BAR plus boost to supply enough fuel.
if you can get hold of an 813 type 044 bosch fuel pump this is not a problem as they will run at 8BAR constantly instead of the low spec ones

Many thanks for the reply, what ecu are you using? Hopefully they should be here shortly and I can get them fitted and get the car back in the rollers to be mapped again

I'm talking about around idle, and the minimum injection quantity. The S40 does batch fire only. It will always fire the injectors twice per cycle.
So regardless of them being 800cc, they must always be fired twice every cycle, and all injectors have a minimum opening/closing time. And in batch fire, this will always be a double hit compared to that of sequential
If it takes 1ms to open/close....then they will always inject a minimum of 2ms worth of fuel
ie equivalent to 1ms at 1600cc.

That just means the ecu needs setting up for the injectors. You wouldn't just fit them and hope would you.
I had batch fire setup on my zetec turbo, no issues. Also opening and closing times should be calibrated for, so it won't work like that.

If there's too much fuel down low because there is too much injector, no amount of dreaming will fix it.

i get your angle now then.
large injectors can be a little trouble some at low pulse widths, although i did find the 60lbs i used were pretty good in batch firing, there was a little hump at low load and low rpm though so had to alter timing to get it to run smoothly enough.
deka's are quite good to be honest with opening/closing times though.
but has been noted that newer generation bosch ones seem to be better at low pwm's now and are even more linear than the siemens, which aren't bad at all.
