When I see that word 'custom' I get a bit wary, one of the things that sold me on the ID1000's is that they give you a compensation table, you can put those values straight into the ecu(motec). Ive used drilled ones in the past and you have to guess how they will behave under different voltage conditions.

It'll be hard finding answers for products not many people use on this forum.
IMO if you want to find info on those injectors, just do a quick google with the injector name and feedback next to it or just google that injector name and look for forum webpages.

Pretty much what I did Paulyy. Just wondered if anyone around here had run them. Interesting to note that they don't recommend running injectors past 80% d/c.

Looks like you are suffering from fretting wear and corrosion. Its not really the fault of the head gasket but the Cometic gasket may suffer from damage faster because of the spring steel ridge that makes up the sealing surface.
Here is a nice book on the subject. Perhaps a good book for reading while on the throne -

As for the injectors – check out the new Siemens Deka high impedance injectors. These things are as good as any of the low impedance injectors and they can be run up to very close to 100% duty cycle without linearity issues.
Here is the specs for the 80lb/hr version – I have been told that these can be run up to 100psi of fuel pressure…!

Interesting to note that as they get over 90% duty cycle they richen up a little. Better than going the other way!

Yep, that's the price I got too Sid. We found that by changing to some new ARP headstuds we were able to get a longer lifespan out of the Cometics. To expand, with the old stock studs we were having to change them over after 2-3 racedays which is clearly pretty crap. After changing to new studs I think we got about 4 meetings and perhaps a couple of mid week test days. When Sean put this motor back in the car we decided to change the h/g again. It was about to blow had we left it so that was a good idea. I'm thinking it might be worth trying one of these Phuzions again depending on what lifespan we get out of this current normal one after the new ECU tune and shakedowns that I hope to be doing next month. Decided to switch to these ID2000's. Going to have to get a different fuel rail knocked up quickly. What injs are you using Sid?
Paulyy, might be worth considering either/both of these products too. Can you log inj duty cycle?

I didn't have that option with the piggyback. With the Motec now I will.
So do we think these new Siemens are 'better' than the IDs?
Oh, that Amazon link didn't work Chris?
