Turblown Engineering FC Rx-7 EWP System - Full Kit
Turblown Engineering's Electric Water Pump( EWP ) kit is a complete bolt on system designed to eliminate the OEM belt driven water pump. Traditionally an electric water pump upgrade yields between 1 to 2 percent more rwhp by reducing parasitic drag on the engine. The OEM belt driven pump requires power to drive it; removing this " frees" up more hp. More importantly an EWP upgrade upgrades thereliability of your cooling system:
No more cavitation like the OEM water pump
No more belt slippage when removing the air pump which is commonly found when not using an idler pulley( even if you have larger diameter alternator and water pump pulleys- the belt will still slip, or even worst you have it torque so tight it will wear out the front main bearing, and alternator bearings)
Ability to control pump flow based on coolant temperature
LCD PWM controller allows cockpit access to coolant temperature and Alarms
Post shut down, engine off coolant control- eliminating heat soak of engine and turbocharger
This kit uses the OEM FC3S Series4 water pump housing & OEM thermostat( not included). This does not require an alternator relocation bracket, or loss of either the a/c or p/s. It also retains all the OEM water connections( throttle body coolant, turbo cooling lines, heater core lines, radiator hose positions). This system can be used on the track, and only differs in ease of installation, cost, and loss of oem functions. The supplied belt on the full kit does require removal of the airpump. Airpump removal not required if using a different length belt.
If you have an Series 5 Rx7 you will need to swap to a Series4 n/a or T2 waterpump housing and thermostat neck in order to use this kit. If you have a 20B engine you will need to bolt on a FC waterpump housing and thermostat neck.
