My stock twins are finally smoking. Im either looking for another set of twins in good condition or just spend the money on a single turbo. Not really looking to make alot of power. My question is whats a good set up for a good price that spools quick. Looking to get between 350-450hp at most if i go down this route. Looking at the BW S360 and GT3076. Also should i run 440cc's or 550cc's? Any suggestions would be appreciated.
