Congrats on your purchase. I had a chance to drive the Si and its a blast. I really enjoy my EX though, but I still dream of that vtec sometimes...

Just a little fyi, your car is a V-Tec engine, just less HP.
Peek Under the Hood
The Civic offers the brisk performance of a 140-hp, 1.8-liter, 16-valve, SOHC i-VTEC® engine that has been refined for 2012 with many friction-reducing and airflow improvements.
yes - that's vtec engaging.So, when I get into my higher rpm and the torque picks up, that's the vtec engaging?
Not to thread jack completely but...Wow! I really didn't know that. I guess we just don't get the cool decals...

Seriously get it into 2nd and floor it. At least once. Light that vtec light up and you'll see what owning an Si is all about. At least that's what I would do lol. I did that on the test drive though. I think the salesman enjoyed it more than me and yes vtec engages at 6200Sport injected!! Damn! I was wrong lol we were placing bets I new it stood for sport but couldn't figure out the i lol
We haven't hit v-tec yet, she brought it up to 4700rpm yesterday and the v-Tec gauge didn't do anything so I figured it needed to be higher
I thought I read on here some where v-tec doesn't engage until 6200rpms I could be full of it though lol
I didn't tell her that either because I don't want her reving that high! LOL
Lol 5k holy crap!!Sorry I mean vtec engages at around 5k for the 9th gen. Was thinking about the 8th.
I myself wonder what and if any gains that can be felt and proven that combo would get. I've seen a few post from people feeling faster but loosing 1/4 mile times with an intake. I can only assume its the ecu pulling timing because of the increased airflow. I'm hestitant on modding the car after reading that stuff tbhI've recently started testing the V-Tec in my Si. I have a great entrance ramp on the local freeway that allows me to get up to 5/6K RPM before merging. Keeping the RPM's up through the gears with the V-Tec lights illuminated has given me a feeling similar to a turbo. It's really given me a new appreciation for what the Si can do. Mine is mechanically all stock at this point, so I wonder how much ECU re-flash, CAI, and cat-back exhaust will improve it.
Welcome to the site and I hope enjoy your Si. I love the white!

How does that make it to where you see gains from mods instead of loses?One word...........Manifold-spacer(actually two words).........

The vtec dash lights start at 5200rpm and go to 7k rpm. I would advise you to use the whole rpm range to break the motor in. Especially with some users who dealt with oil consumption. I think some said they never went into vtec or high rpms initially. I'm not trying to scare you, but I'd advise you to drive the car into the high rpm ranges randomly for proper break-in.

I read the the details. I guess my question is is the reason people are loosing times with an intake because the ecu is pulling timing? Does the flashpro or reflash take care of this? It would suck to buy an intake and exhaust and lose power. So I'm wondering like the above poster if combining that with an ecu flash would make you actually get the gains your supposed to from those mods. Knowing the answer to those would let me know if basic mods are worth it on this engine. OP sorry for accidentally hijacking the thread. I'll stop after this.P2R Throttle Body Spacer Description
A P2R throttle body spacer is one of the most cost-effective and simple power modifications you can make. This 3/4" throttle body spacer is designed to fit in between your intake manifold and throttle body, creating a larger volume of air in the intake manifold and optimizing the air path to the cylinders. Tests on a 06 Civic Si produced a 5 horsepower gain to the wheels. Other applications will see similar (or greater) gains. For such a simple modification, this is a great gain! In addition, this spacer can be used with P2R throttle body gaskets (if available) to further increase horsepower gains (we recommend buying two to cover each end of the spacer).
Key Features:
Fitment Notes: Because this spacer effectively "extends" your throttle body position, some aftermarket intakes, especially cold air intakes, may not fit as intended by the manufacturer. For most Honda Civics, simply loosening and re-tightening the intake is all that is required for proper fitment.
- Very simple and inexpensive modification that adds 5+ wheel horsepower!
- Comes equipped with a 1/8th inch NPT threaded port (except on R18 spacer) that can be used for nitrous or as an extra vacuum port.
- Includes extended bolts and plug.
- Available in several eye-catching colors, and polished to a brilliant show-quality shine.
- Can be used with P2R throttle body gaskets to further increase horsepower gains (may not be available for all applications).
