Hey everyone, I'm new to this site...great layout and color scheme BTW.
I'm getting my s14 turboed sometime next month.  I have a t3/t4 turbo kit lined up w/a revhard manifold.  I'm only planning to run >>>LESS THAN 7PSI<<< and also keep in mind this is my daily driver, so in terms of fuel delivery, what would I need to upgrade?  I was told I would just need bigger injectors, fuel pump, and an ecu upgrade.  Is this true?

yes, but under 7psi, u really dont need the fuel pumo, be it doesnt hurt to have it, u will need to drop in 370cc injectors and send your ecu out to JWT.

the other much cheaper and less reliable route would be to use a rising rate fuel pressure regulator, ideally with a 10:1 on boost.

Why 10:1?  doesn't nsport use 7:1?
