Hey guys, I'm thinking about upgrading my 2000 GSR. I'm inexperience when come to the car but I want my car to go really fast. Basically I'm not sastify with stock engine. Anyway I've been doing some research but still can't decide which is better supercharger or turbocharger. Any advice will be helpful also what other things do I need to upgrade since I'm going to be putting more horsepower to the stock engine. Oh and 1 more question how much does installation runs and how long will it takes?
