I have an 04 s2000 with an Amuse R1 Titan, T1R test pipe and AEM V2 Intake to cover the engine modifications.

So, I am planning on going to the 1/4th mile track and I have a week and some money to prepare for the best possible time.

I was just curious as to what brand of fuel rails, fprs, maybe injectors and anything else I would need along with the wideband ems. And also what gains with a good tune these would all provide along with the other modifications.

I plan on going turbo in the near future so doing the fuel stuff and ems will benefit the future, I am just curious as to the benefits now.

I've searched plenty on the ems and hear 10-20whp ect ect...

The last time I dynoed was only with Amuse Exhaust and I did 215whp I believe.

What should I expect? Thanks! Or any other suggestions as to what could be more beneficial to me.
