[si23]

i have th 06 si and i have aem intake a dc exhaust, thats all u should start with whenever u do start modding but i agree with the waiting thing b/c u can appreciate the change unless ur used to the stock hp.......after that tho i got the hondata reflash which reprograms the ecu to put the v-tech at 4500 and again at 6000 and puts the rev limit to 8600.....it did wonders its a whole new carand the pickup off the line is soo much better now

yeah... Im not familiar perse with anything over 2000 (that generation) Civics... but what this guy just said tells me that he's running a K-motor with dual stage Vtec... erm... sorry "V-Tech".... lmao..

So.. umm... unless these cars DO have dual stage Vtec... and the only motor that I personally know of is the D15B with Vtec-E, can someone please explain what this (I'm thinking flamer) is talking about?

sounds like a newbie to me. V-tec is good for better fuel economy, but these kids now days just think v-tec is like nitrous or something. V-tec engines have cams with two different cam profiles. one for fuel economy and the other lobes for inhanced performance. I believe i-vtec changes ignition timing as well. theres no such thing as duel vtec it only switches over once. K-pro is a ecu reflash. it changes vtec points for increased power along with timing and fuel modifications. not to mention higher rev points.

I like the new SI. it's deffinately the best SI yet and the k-series engine is tough as nails, but it is fwd which limits one horribly. for 2-4k more i can get a slightly used evo, 350z, sti, wrx, gto, trans am. or even mustang. If you wanna go fast for the 20k range theres 100 better ways to go.

The "two-stage" Vtec he is talking about is correct... Kinda. i-Vtec works based on throttle position. WOT engages the second cam sooner. I still don't have all the details down pat, but I will say this, when my guru was programming his friends k-swap with the k-pro, he simply threw the i-Vtec out. Not something he favored. But yes, it does work differently than traditional Vtec.

Oh, and I'm getting the reflash this week! Can't wait to see what NEW V-8s go down now! Then there's the track event in November!

Yo i dumped an AEM cold air intake and a magnaflow exhaust system in my 07 Si so now it's up to the next upgrade, dumpin a Hondata reflash into my 07 Si but don't knw of any good shops where they can install it in Arizona. are there any cons to upgradin the computer, if so how long will my engine last if the car is a daily driver and i only race on the tracks (1/4 mile)once in a while? What headers are the best ones? What other mods can i install?

Here's a mod you can install... it's called the "MAKE A NEW THREAD" button... simple... next time you feel like posting something, don't bring a thread up from the grave to do it... just "MAKE A NEW THREAD"... see how it works?
