here's my punt..
Looks as if Chev LS1 (0-280-155-931) will do OK.. they flow at 26lbs at 3.0 bar..

This site is normal pretty good for prices http://www.fiveomotorsport.com/ or you may have similar in Oz (hopefully)

They are who I bought my red tops off of but never fitted them.BB
So I'll be selling them...
We never seem to get arrive at a clear answer to which injectors to fit for different uses.
There seems to be Type 2 and Type 3 Bosch in different colours. What’s the difference between the types?
I currently have a naturally aspirated 500, tuned to 330bhp. I want to improve this, but will eventually supercharge. So, I want a set of injectors that won’t need replacing again when that happens.
Which would be the best injector to choose?

Bosch Red top (Type 2) give a pencil jet.
Bosch Red (Type 3) give a mist.
I dont think there is much in it but I went the type 3 ther more modern and smaller, also they work at much higher pressuers as well so room for futur modding. They give a very fine mist which is supposed to be better as the droplet are very small. they should be good for 400 bhp + with forced induction.
Don't go to big other wise idle fueling will become a problem. I think type 3 are 34lb.

The ones recommended by your preferred supercharger supplier.I am running Type3 RedTops from FiveO on my car which Mark Adams has mapped and is happy with the margin of redunancy i am getting from my current setup.
I originally fitted the redtops to my non S/S 320bhp engine as it was running lean at high revs, it made it run super rich at low rpms and on start up so did need mapping.
Here's an update:
I've compared the Chev LS1 Bosch injectors (0-280-155-931) with the standard Lucas Green band injectors and have the following information:
Regarding flow, the 0-280-155-931 injectors are rated at 28.55 lbs 300.1 cc/min at 3.0 bar.
As the Lucas injectors are rated at 2.5 bar, all testing is done at 2.5 bar. The Bosch injectors(right) as expected had more flow with a finer spray pattern than the Lucas(left) injector
and a little more magnified
Next step is just install these injectors without any other mods...

MoJo,
The reason I went through all my testing was because I couldn't find any info regarding these injectors. Mind you I am not located in the UK: maybe there is more available to you. One the other hand, info regarding LS injectors abounds which is why I went the way I did.
Looking back, it's been a year since I did my testing and my Griff, now complete with Stealth can is running VERY well.

Just an update to close this thread.
After ECU tuning I am happy to report a substancially smoother idle with less AFR variation and a noticable difference in mid-high range torque which I put down to better atomisation.looking at the example on test what atomisation
Next mod is a stealth cam..
