Hi,
Current mods:
Turboback-exhaust with Custom ECUTEK-map

I have been looking at doing another mod on my STI -2003 which is to swap turbo to a TD05/06.
I am aiming for somewhere around 360hp!

Will std. STI injectors will be enough when using the bigger turbo?

What size of injectors are you TD05/06-guys running?

I have power enterprise 550cc with TD05/06 on a sti4, i think new age sti's have 505cc as std and should be good for close to 360. (i think)

Thanks for the reply!

I thought that the oem new age STI injectors where 565cc?!

I hope that someone can verify the oem-size on this forum too?

503 is the actual size, you would need 650cc with that turbo (or should), fuel pump would need changing (if not already) but leave the oem pressure reg alone as that gives the correct pressure ratios even with the higher flow pump.

Bob is that to say with TD05/06 and 550's i'm not going to be getting near 360bhp? on an STI 4.

Thanks Bob!

Yes, I have already been adviced to use PE650cc along with a ECUTEK-remap, I just thought there was a way of mapping 'around' the injectors maxing out and not use the full potential of the TD05/06 and save the bigger powergains until the upgrade to 650cc.

But I guess it is better to get turbo and injectors at the same time then!
