Default 05' S NA Driveability thread

Good morning S2Ki,

im starting this thread, having recently purchased an 05 silverstone AP2(obviously). my goal is not an obscene HP figure, but a driveable car that is more so than a stock AP2.

the car already has a CAI by AEM. its so so in quality. id like a mugen or spoon carbon intake instead.

anyways. im looking to ballpark around 220+/- at the wheels. and 180ft/lb. these numbers are based off of power per dollar of bolt-ons so im not looking for a ridiculous increase over stock figures. so i looking into a few mods. and id like some REAL, reasonable feedback that is supported by factual information not limited to dyno results.

mod 1: uk mod, exhaust(short term)

mod 2: 70mm HFC mid pipe(long term)or possibly just a test pipe(CEL MOD)

mod 3: apexi, S-AFC NEO or hondata ECU(long term)

mod 4: invidia Q300 w/ oval tips(long term)

mod 5: (possibly) larger than OEM throttle body.

the short term uk mod is just for audible enjoyment and slight flow increase.

the long term mods are projected to remain for the duration of ownership.

i want to lower the vtec rpm activation point and re-tune for that. 6k is ridiculous. a proper tune would really boost the mid range. and these other mods if properly tuned would increase the low range and drive-ability.

furthermore, i have a set of 9.5" wide 18" gold star rims, to get rid of. PM me for pics and make an offer.

i will post pics of the car tonight.

Congrats on the AP2, & welcome to s2ki.
I'm not sure if you can control ignition timing w. the neo, but thats where power is made ( in short )
Bolt ons are nice, but everything is better with a tune.

I suggest long term upgrades only.

Some drop in cams will give you some great mid-range gains. BC stage 2 cams are pretty popular. They are pretty mild and will not hurt driveability at all.

Don't mess with the NEO. If you get a test pipe, HFC, or one of my mid-pipes (best gains, especially in the midrange), you would be able to achieve significant gains by lowering VTEC all the way down to about 4K RPMs. However, the NEO wouldn't be sufficient for that much of a change. Depending on whether your state requires the car to be OBDII compliant, you may want to consider getting an AEM or Haltech instead of the K-Pro.

@gernby, i am not required to do emissions testing. i am not familiar with the k-pro. and as much as id love one of your pipes(your craftsmanship is outstanding), i absolutely cannot afford it. also can you elaborate further on your reasons to not mess with the NEO?

the cams sound reasonable, but will definately need to be tuned. so an ecu piggy back and the cams would be required at the same time.

a flywheel is very reasonable, requiring no modification to fit it, and i could even service the clutch at the same time.

The Hondata solution that would be compatable with your model year would be the K-Pro, which is quite expensive. If you were thinking about a FlashPro, it is only compatable with '06+ models.

The NEO would not allow you to add fuel or adjust ignition timing, so it is really not good for much other than minor tweaks in VTEC engagement and / or to remove excess fueling. Don't waste your time with it.

if that's the case then your choices are haltech, aem or hondata. ditch the neo. you're never going to achieve the same results with a neo as you would with a full standalone. i've tuned my ap1 with a standalone and bolt on modifications. i've posted my results here:

https://www.s2ki.com/s2000/topic/909...tepped-intake/

you can expect similar results on an ap2 but with more mid range due to the larger stroke.

Biggest difference in drivability on my ap1 was installing KPro and the lightweight flywheel. Test pipe for lower vtec is a no brainer as well.

If you have a good tuner in your area, get AEM or Haltech, if you don't, save for KPro. That's my two cents.
