Scion TC w/TRD supercharger vs. RSX type S?
Wow, i can't beleive all of the misinformation in this thread. Before you guys call me a hater, im a avid honda fan and have been working on honda's for almost 7 years. My last honda was just stolen and im in the market for a TC, so i've been lurking behind the scenes for a few weeks doing research. Anyways, this thread inspired me to register so i can help clear some things up for you.
Rsx's do not have vtec, or vtech. They have I-Vtec, and trust me the extra umph in power is not even comparable to a supercharger in anyway. Let me explain it to you so you will understand how it works.
I-VtecAt low RPM, the K20A2 (RSX Type S Motor) uses a normal cam profile to retain a smooth idle, good fuel economy, and good low-end power delivery. At 5800RPM, its VTEC mechanism engages a high-lift, long-duration "race" cam profile to increase high-end power delivery. The only difference between this i-VTEC engine and the older VTEC engines is the addition of the VTC system (See below). The intake camshaft has the automatic self-adjusting cam gear which continuously optimizes valve overlap for all RPM ranges.
VTC - Variable Timing Control. This is a mechanism attached to the end of the intake camshaft only which acts as a continuously variable cam gear - it automatically adjusts the overlap between the intake and exhaust cams, effectively allowing the engine to have the most ideal amount of valve overlap in all RPM ranges. VTC is active at all RPMs.
What does this mean? It basically allows honda to squeeze more power out of low displacement motor. The car will have good gas mileage and basically it only uses power as its needed. If your driving normal around town ivtec its not engaged and your saving gas. If your out raping the streets then it puts all of the power it can make to the ground. That being said, toyota has developed a similar system. Im not sure really how it works but i do know that its not as advanced or complicated but it has the same benefits, better gas mileage, more power when you need it.
I hope you are joking, i will assume that you are, since i know you from other forums but in the event that you are not joking. Vtec does not consume oil or burn it, it is powered off oil pressure but thats it. You can feel vtec on any bseries motor. You might not be able to feel it on your whimpy d16z6 but you will definatley notice it on a bseries. Want proof? CLICK HERE to Watch this video of my car on the dyno before i put my turbo on, now do you really think that diffrence could not of been felt?
Now that we are all done with that, I would assume that the trd supercharged TC would beat a stock rsx assssssuming that the car could get traction. However, with little money, you can get your rsx to the low 14s hight 13's. Several people on honda-tech have hit 13.9-14.1 with just a hondata reflash, and a aem cold air intake. , and better tires.. It doesnt take a supercharger to make a RSX fast.

You cant compare apples to oranges. Stock for stock, the Type-S would beat a tC. If you want to compare forced induction, oyu have to supercharge a Type-S too.
Also take into consideration that the Type-S redlines about 2000rpm higher than the tC. So while we're shifting, they're still pulling through the gear.
Dont get me wrong, I love my tC
All I'm saying is that you cant compare a forced induction Engine to a N/A Engine and then brag that it makes more power.
What you can do, though, is take the money you saved from not buying a type-S and turbo the sh*t out of your tC and brag that it was still a better deal!

instead of comparing FI tC and NA RSX (or complaining about it)...why not just compare in something that the tC takes the cake in.....such as: a 25,000 acura and a 17,000 tC....mod the tC up to 25,000 then it's even.....simple....
the rsx type S does't cost $25,000. it's $23,500. and that is so lame to think that way. that's like me saying well my acura only cost $23,500 and an nsx costs $90,000. if i were to drop $66,500 worth of mods in my S i would smoke it. it's just stupid.

i understand what you are saying and i'm not taking it as bashing. no doubt you can take a lil $3,000 hatchie and dump about $10,000 into it, yes it will smoke my car. it's just assanine to me to think like that tho. most people in here claim that they can't wait for the trd SC to come out, but in reality a good 75% of them will not even get them. if they didn't want to fork over an extra $4,000+ on a car what would be the chances of them doing it now? i know some people bought them cuz they think it will make a great project car but most people bought them due to the fair price, looks, luxury, and ok performance. and for the people that do get the SC, when it comes out, most likely they will have to spend more money to maintain it and not to mention upgrading some equipment to make sure it will be able to withstand the extra power they are going to get from it. ie, clutch, brakes, suspension, tires, etc. so in reality you will most likely pay well over the price of a type S, that is if you don't go cheap on performance parts and get the real thing, and it will still be a lil bit faster than the S if it is.
The TRD s/c isn't going to put down enough power to warrant upgrading the brakes/suspension. I think that most of the people who want the TRD supercharger aren't looking to be the fastest car at the track. If that's what you're going for then you'd probably look for an aftermarket turbo.

The suspension is a good place to start on the tC. It is fun to drive stock, but a little too much body roll.
The TRD SC is designed for use with the stock clutch. It is supposed the be designed as an option on a stock tC, and with the numbers that some people give, it will not warrant a stronger clutch unless you are beating it too hard.

Maybe that would justify aftermarket headers?
