| The GT725R kit is more suited for applications aiming for extreme top end power. Additional injectors will in no way help you overcome lag, regardless of the turbo kit. They just help supply enough fuel at top end (when the engine needs the most fuel). Our GT675RS kit is built using the exact same new Garrett turbos as the JWT 700BBs. Not sure why there still seems to be confusion on that issue. We feel out GT675RS kit is a better choice for street use compared to the GT725Rs, because it is still fairly responsive and yet capable of 700 rwhp, which is alot more than anything "usable" in a street application.
