I have done some mods to increase air flow to my engine and man did they work... perhaps a little too well. I feel that it is time to up the fuel system before I lean out while enjoying all the freeway has to offer.

My questions are simple:

1: Can anyone who has a S4 NA with a rather heavily ported intake manifold please give me some direction on the size of fuel injectors I should get?

2: Will a TII fuel pump be enough, or should I look into an FD of aftermarket?

 

like everyone sez around here...the na's dont need fuel upgrades unless ur going pp bp

 

So I can run with a TB mod, highly ported intake, open catless exhaust, and no emissions and fear not?

Works for me, I was just starting to worry a little. I haven't experienced any detonation it my rex, but there is a first time for everything.
