You're going to hear 'do a search'... so that's probably the best place to start... this has been discussed numerous times on this forum. The 'Speedcraft' turbo can be purchased from Stage 6 Motorsports and you can call them at (904) 777-3250 for $5,600 or you can buy it from Speedcraft Engineering which isn't Speedcraft Engineering any longer for $6,200. Turbo is much better if you want to go fast on the street.

You will get various opinions on which is better for track use. My guess is the turbo S2000 will have an edge there as well... the argument of turbo lag just doesn't hold water any longer. The ball bearing unit that the Speedcraft kit uses spools up very easily and the turbo will make substantially more torque across the rev range which should make for faster exiting of the corners and will also be pulling more mph in the straights.

Simply put, here are some comparisons:
Supercharger creates boost via a belt driven pully powered by the serpentine belt. In other words, a supercharger takes power to make power. This is less efficient (street, track, driveway, anywhere!) than a turbo which creates its boost from the passing of exhaust gasses. Basically, the turbo takes what would be deemed as waste and uses it to make power. The ball bearing turbo as derryck previously said spools up VERY quickly. I would venture to say that I am at full boost as early as 3500 rpm. In addition, a superchargers boost curve (or line as the case may be) will always be directly proportional to engine speed. A turbo on the other hand can be adjusted via the wastegate. I think that anyone interested in going FI on their NA car should take the time to go to the local book store and purchase a book on turbocharger / supercharger basics to understand why and how they work as well as the difference in applications. It would be $10 well spent.

In my experience in talking to people, anyone who doesn't know what they want wants a low boost (.3, .4 bar) turbo that spools very quickly (3000, 3500rpm) with adequate intercooling adding a pressure drop, but a o2 density gain. e.g. cooler air.
My $0.02. If you want more info, search, get some books, etc.

I'm grateful for every person willing to create performance products for our car. As they increase in number, we will have more available at better prices. I love the free market system, don't you?
