Fuel Injectors

I am looking at getting HKS 550cc however i am wondering if its just worth it to upgrade to 740cc, or 800cc or if going to big to early can cause damage?

Also The only brands I can really find are HKS and AP. AP has some affordable 740cc. Is this something I should go ahead and go with or what are your guys thoughts?

Deatschwerks and Injector Dynamics are the big names for Subaru injectors.

I would just go to 750+ and be done, but what do you need injectors for? Are you maxing the stock ones out or planning on getting a bigger turbo or E85?

I pretty much agree with Chris. Letting us know what you need them for will help to decide what size to go with.

Also, to answer your question about going too big: you need to tune for the injectors anyway, so it wouldn't hurt anything unless you didn't get it tuned.

I believe that 550cc injectors would work, but going with 650cc would not be overkill. As if/when you add either you will need a tune for the injectors. So you can get the injectors, but I would hold off on installing them until you have the turbo, or at least a DP, and some other mods that require a tune also.
