if you want to run larger injectors you will at least need an emanage... but to be honest, if you've gone this far, why not go all the way and get an ems....

oh and while your at it.. as the s/c at 12psi won't be doing it for you anymore, why not get the turbo you should have originally gotten

 

Paint the CF, would make the car look much better, I promise...unless you had a complete carbon fiber body...I forget who makes one for the S2000...
