yeah i have a 03 s2000 i have exhast, intake, fuel regulator, aem standalone, and stunk 2 stage 2 cams and im only making 216 whp...... now i ask the guy if i put bigger fuel pump and injector will it make a diffrent and he told no it b the same which i think is b/s cuz more fuel is more air and more power i wanna know if her is talking b/s about the fuel system upgrade and did he tune the standalone???

 

 

^lol. 216 sounds right depending on what kinda dyno it was on. the s2000 isnt a very na mod-friendly car. intakes add like 6 hp so i dont know if a tune is gonna do you wonders if you're looking for like 100 hp gain.

 

Well...not really...it's the other way around. Just because you add more fuel does not mean you will get more air.

If you can figure out how to get more air in the combustion chamber, then you need more fuel and that will make more power. How do you get more air in the combustion chamber? Turbo or SC...

An AEM EMS allows a tuner to set the air fuel mixture and timing so the engine makes the most power. The s2k tends to run rich, so adding a fuel regulator, bigger injectors and bigger fuel pump is just a waste since it needs to be leaned out.

 

Correct me if i'm wrong bue the s2k comes with 345cc injectors from the factory. That would support pretty much anything you could come up with for an n/a setup. Unless you're going forced induction you would definately not need a fuel system upgrade. You dont even need that fuel pressure regulator that you're running

 

Did you dyno and tune after every mod? Some of your mods may not have actually added power. Cams so far are unproven.

Cams could be killing your power. The mods you have minus the cams should be giving you about 15-20WHP. I would ditch the cams and FPR and pick up a test pipe. You also need to make sure you match your cam profiles to your header, they could be working against each other

 

yeah have headers on there so the cam should b work good

 

You should go back to your stock cams and re-tune it to see if the cams are doing anything. Similar setups make 225-230whp with stock cams.
Also, what headers and exhaust are you running?

 

Well I have megan header and apexi exhast dual
