Hi All,

This has probably been asked and answered many times before, but I've got to keep you all on your toes

What injectors does my STI have and what is the fuel pump rated at.

Will I need to change any of these if I get a VF34 or the new GT turbo.

Cheers

you will have 440cc yellow top injectors same as the WRX (99/00)
not sure of HP rating of the factory pump but its a good idea to replace if you get a new turbo.

Fuel pump upgrade is always a good idea for reliability.

Injectros may get to unsafe IDC's depending on boost/afr's of tune. Again, probably not bad reliability idea if you are going to turn the wick up a fair bit and run 18+psi.
