Turbocharger is far more eficient. you get much more torque and hp.
It also develop less heat, and that of to reasons, it only create boost when you need it, and it doesent beat the air. The down side is turbo lag, the larger the turbo the more lag. And turbo is more reliable than the supercharger, especially on high rpm engines cuz of the belt.
Put a small ball bearing turbo on your s2000 and you will fly, but the cost is higher. I am going for cams though, because, there is a lot to gain in that rpm range, i had a rally car in 93, that was a 2.0 with tbīs and the lot, but i put out 283 hp at 7750, and had a very flat torque querve with over 200 pounds starting fron 4600. iI bought it used and raced it for at least 20000 miles with regular maintenence. It was the legendary v20xe opel engine in a 79ī ascona.
