The Bridge-Port Stage 2 engine rebuild commonly known as a Half-Bridge has its inlet and exhaust ports enlarged to increase the breathing capabilities of the Renesis engine just like the Street-Port, but in addition to this, the Auxiliary and Secondary Ports are bridged.
The Half-Bridge retains stock idle characteristics but power and torque are increased significantly over the middle and upper rev ranges. The Half-Bridge comes into play between 3800-4200rpms when the Secondary Port (SSV) opens, giving you more power all the way to redline!
Those with a 192Bhp or 4 Port engine will get the stronger 231 6 Port stationary bearings modification as standard, meaning there is no reason why you need to stop at 7,500rpms like you used to but now you can increase you redline to 9000rpms! This conbined with the Stage 2 porting option is a great combination which will add significant power compared to stock.
