fuel injectors for my build
 

right now im in the processes of building my s2000, list of parts so far

-j's racing single titanium cat back
-j's racing wrapped header
-ballade sports ported intake manifold
-ballade sports ported throttle body
-takada intake
-mishimoto rad & fan
-okada coil pack
-aem ems v.2

my question is, would this build make more power with larger fuel injectors (440cc) or should i just stick with oem ?

Unless you are going to use E85 or similar fuel oem should be enough.

i'm a proponent of buying id1000s if you are buying anything, gives you room to grow and you get one of the best injectors possible.

Don't see any reason to go beyond what stock can handle here.
