I drive a 93 sol si. I was wondering what would be the best thing for me to do. I would like to swap but if its not necessary then I will not. Im running a D16 right now. I am looking for more horsepower. My budget is negotiable .What would be the best to do. Should I simply turbo my D16, should I swap in B20 and turbo that, or should I plop in a B16a and keep in n/a. I am looking to keep this car street. Any form of information, opinions, or advice please respond. It will all be mulled over and very valuable to me. Thanks in advance.
