Dude let it go already. I know the difference and got lazy with my words. If I had the energy to I could argue that VVT-I, VVTL-i, VTEC, and i-VTEC, and for $hits and giggles even MIVEC, and VANOS systems are all the same... but I'm not going to because thats a whole other can of worms.

okey here we go.
Honda's VTEC system uses more than one cam profile per cam, for normal driveing the engine uses the mild profile. Once the engine is at a certain RPM (and assuming all the temperatures, oil pressure, load, etc. are met) the ecu sends a signal to the VTEC solenoid that engages, thus sending oil pressure to the head and all the necessary parts to engage the VTEC profile on the cam thus creating more power. Honda did this so that they could make powerful engines but still be efficient on gas. VTEC debuted on the B16 and C30? engines in the early 90's. (I may be off on the date, and possibly the engines)
Toyota's engineers around the same time created a way to advance and retard the timing on the intake cam via. hydraulically controlled actuator on the intake cam. This resulted in a smoother operation than VTEC because there is no sudden change to a secondary cam profile. They designed this also for fuel efficiency and power when needed, the the engine revs through out its powerband much smoother but still lacks the power compared to VTEC because VTEC has what some people would call a atreet profile and race profile on the same Camshaft.
VVTL-i was introduced to compete with VTEC, it works similarly as VVT-i but also uses oil pressure to switch between a low and high cam profiles. (Pretty much VVTL-i creates the same effect as VTEC but you still have adjustable cam timing.)
Anyone want to guess what iVTEC is? Thats right iVTEC = VTEC plus VVT-I.
Now do you want to test my knowledge on valve clearances for these motors next or are you going to give up and admit I know what I'm talking about?

*sigh*
this bantering needs to stop NOW.
if it continues i will lock and clean the thread, then re-open it.
and if it continues after that by the same people, they will be given the appropriate repercussions.
i didnt think this was going to keep escalating.
if you guys want to argue about VTEC and VVT-i thats fine, however this is not the place for it.
make a new thread in OT if you want to continue you argument.

I apologize for my part in this thread going way off topic. Now lets move on...

When and where did I bash the OP? As far as the intake goes...I may have shown sarcasm but I never stated that the OP was foolish.
Now for considering that the tC and the Civic are of the same genre... Hell no. Honda has always made well handling, fun to drive sport compact cars. They usually come with well designed motors with power. The tC's 2AZ-FE may come with Toyota's version of VTEC but still lacks power, Not to mention the tC's power plant is heavy and lacks power compared to any D, B, or K series motor. Suspension on the tC is lacking too. Civics come with double wishbone suspension, better brakes, and the chassis are way better designed for conering. The tC was desgned inorder to fill in a void in Toyota/Scion's line up. They made a 'pretty' car to customize. Honda has built well handling sport compact cars for the past 20+ years.
Now, Don't assume I'm a Scion bashing Honda lover. I've been messing around with all kinds of cars, (Toyotas, Hondas, Nissans etc...) Not to mention I own a Scion myself and I love it way more than my Honda's and Nissans but I know where my car is beat.
To the OP:
I commend you for trying to make an intake with what you got, but where you failed is that your intake is still un supported, and you are drawing in warm air, at this point you're better with the OEM airbox and a K&N filter. The point of an intake is to get cooler air into the engine as well as have a smooth path for the air to travel.

hahahhaa VVTI =/= Vtec, not even close
VVTI =/= iVtec either
