Id like to install a set of coilovers. Any advice?
Check out RonaldBrownJr’s club site. It’s called Ack Repair. He has step by step photos to guide you through the mod. I Return to “Modifications” Top Performance I noticed the Vigor intake manifold has two paths, controlled by a Bypass Control Valve. When the valve is open, the engine has more power. If I “fix” the valve so it stays open all the time, will I get more power? No, at least you won’t get what you’re looking for. An ordinary intake manifold’s geometry will favor either high-speed power or low-speed torque… or else it will be a compromise. The Vigor’s two-stage manifold allows it to deal better with the the breathing requirements at different engine speeds. The effect it has on engine breathing is very similar to variable valve timing, which Vigors do not have.
