Can i save a few bucks short term and upgrade the fuel injectors to RSX Type S and upgrade the fuel pump/return system later?

Rather, is it absolutely necessory to upgrade the return system/pump?

Thanks

Yes, you can just use the rsx injectors (i hope you mean with emanage or some fuel correction) and no upgraded fuel lines.. but once you reach a high psi (usually past 8) your gonna wanna go return

what about running 12 psi, with a fuel system like TSIs, properly tuned? I believe 12 would be ok. I want to run 12 at the track and like 7 daily. for now that is, til I wanna step up some internals.

TSIs is like a carburater that spray extra fuel into the manifold. It is ok for around 8psi, but running 12 you are more likely to run into problems I believe. But for the track, Ill be fine. You dont need to do anything to the stock injectors other than get more fuel out of em, huh? maybe not even
