550s will work, 650s would be better.

The injectors by themselves will be worse for your car unless you have a tuning device to account for the larger injectors. If you have that, then you could bump up the boost a little bit. But on a 2G (with the OEM BOV and the T25) it will not be much before you reach the limit of the T-to-small turbo and the leaky BOV.

im running a greddy typps s... not the stocker.

so inectors should wait?

If you have a tuning device you could put the injectors on and get a feel for tuning your car. Without a tuning device...don't put the injectors on.

Just a suggestion, but if you have done any mods at all, please list them in your profile so the members can better advise you on stuff.

^^^ agreed. But to answer your original question, I'm going with the denso yellow 510's. Larger, but not overkill. I plan on getting the evo III 16g and this will be a perfect match.

I run 550 with Maf-T and it is easy to tune. Also I recommend in getting a FPR, a Tuning device(SAFC,MAf-t) and a Logger.
