Show original supplier description
The VRP M113 NA Supercharger Conversion Kit offers a comprehensive solution for boosting the power of your naturally aspirated M113 engine without the expense of a full motor swap. This kit provides the essential components to transition your engine to a supercharged configuration, allowing for enhanced performance and impressive power gains while maintaining the engine's original compression ratio. A Boost Bypass Delete is also provided to improve boost efficiency and power delivery. Additionally, you'll receive a new belt and a thermostat housing to ensure smooth operation and proper temperature regulation under load. To successfully install this conversion kit, several additional components are required. These include a factory M113k Supercharger with intercooler and surge tanks, a custom-built intake and PCV system, and an upgraded cooling setup (pump, reservoir, and heat exchanger), which is mandatory for maintaining engine health. Furthermore, at least 550cc fuel injectors are recommended to ensure adequate fuel supply to the modified engine. It is important to note that VRP does not provide technical support for fuel systems, tuning, or ECU modifications. For this conversion, you will need to source a virginized K ECU and wiring harness. Additionally, be prepared to modify the secondary air pump bracket by cutting it off the timing cover.
