OK well I sat here and read all this and somethings make sense to me and alot of things don't and I am sure that you are still are a bit confused Platinum_Civic so let me give you your answer.

Though the supercharger was a nice idea from jackson racing it is not as great as it is made out to be. Yes it makes power, yes it gives nice punch in the low end of the powerband but, the charger is very limitted in the power that it can make. It's not because the size of the pulley becuase you can get 10psi out of a JRSC with a stepper pulley and I think it's the crank pulley off a CRV (someone correct me if i'm wrong there) what limits it's power making ability is heat. You see where the JRSC sits in the engine bay and the heat soak from the motor and not to mention when making boost the heat generated from compressed air leads to no good things. Now to prevent detonation you must retard timing, run colder plugs, and run the car slightly rich to have the fuel try to cool the cylinders down and while you do each one of those things, your power output goes down with them.

Turbochargers, though you may say how can I complain about the heat on a S/C and not an exhaust gassed run air pump, let me explain. What makes turbo's so great is that they are easily upgradeable. To make more boost is as easy as (in most cases) turning a knob on your dash board. When you reach the turbo's limits and you need more, you can always swap out for a larger unit. Now heat, heat is always a factor but there are 3 things that make turbo's a better choice in my eyes when it comes to heat. Turbo's need oil, not only the lubricate the turbo but it also helps keep the temprature of the unit down. Some turbo's use water to keep the tempratures down and some turbos use both water and oil to keep the tempratures of the unit down. Though water cooling and oil cooling a turbo will not make the turbo run cooler than a S/C, what puts the turbo on top is the front mount intercooler. Cooling the charge air down before it reaches the motor is the biggest plus in any forced induction system. Helps with detonation and helps make more power with the same amount of boost.

Another main factor in forced induction is fuel management. Though what comes with the kit should be efficient is most cases is not. When companies build their kits they use a test vehicle, though it is the same car that you drive it is not the same car at all. Every car that comes from the factory is built the same but they do not all run the same. Some run stronger than others for reasons unknown. Every person who force induces a car should own a standalone fuel management system. Not only does it give you full tuneability but it will help with daily reliability. Though expenisive there are no short cuts when you are looking to build something fun, fast and reliable.

Now to get to what JRSCB16A2 said "and if you really stop and think about it.....does a honda motor need more low end torque or more high end HP.....hmmmm." The answer to this question is, NO ! it does not need more low end torque. Why would and engine so rev happy such as the B16 need more low end torque when it wouldn't benifit from it? When racing, you line up at the track and launch the car at a high rpm looking for the best hole shot you can get with minimal or no wheel spin. Why? because wheel spin = bad 60ft times. Your on the highway crusin at 55mph in 5th at about 3,000rpm someone rolls next to you and you decide to hand him his ass so what do you do? Clutch in, drop down to 3rd, Gas it to kick up the rpm and boost clutch out and he is now reading your liecense plate. So now why is low end torque so important?

So my answer to your question is Turbocharge. If you have any other questions feel free to ask. Post here or you can e-mail me.
