Which is more cost effective for a 3.8 Genesis?
 

Turbo kit or supercharger kit?



I see turbokits.com has a kit for around $6,500. I was told by a few people that a supercharger would be close to that price too. I know with a turbo you can change boost levels and have more or less depending on your needs, where as a supercharger is just one level unless you change the pulleys. I wouldnt need or want to change levels and would just leave it set at a specified amount. My main concern would be reliability and something that will last for years to come without having to mess with things.

A well-engineered kit is as reliable as any other. If you want more power, you will likely want more once you get it so turbo.
