The 560's in the STi will see you fine to about 400bhp.

The cheaper option would be to keep yours, and get a fuel pressure regulator, and bump the pressure up a bit.

Or, get some 650cc's or 750cc's if your going to go for big power.

I'm sure STI injectors will max out before 400bhp?? Either way they won't support a tdo6.

Hi MRC !

Lot easier to add a an up-rated fpr than to change the injectors, an extra 0.5 bar saw my std STI pinks running at 94% for 400 bhp.

I'm running TD05/06 20G and ran 420bhp on pinks (with fuelab fpr). They were maxed, but it's possible!

I would prefer to get the injector that is fit for purpose, for the power level at hand, at standard fuel pressure, with good headroom.... in this case, I would not run standard pinks to extract 400bbhp.

When I was running pinks on my Spec C, it was making about 375bhp and duty cycle was at 90+%. This was using a Spec C uprated fuel pump and standard pressure.

I would suspect that for a TD06 you would be better off getting 650's.

More than one way to skin a cat, as you can get the pinks modified to flow a lot more, as well as changing the FPR to bump the pressure up etc.

Plenty of choices available.

I've been running with the 550 pink injectors on 422bhp / 400lbs mapped by Pat Herborne on my 2004 new age and it's been running fine. Have done 13k and no probs whatsoever.
