Turblown Engineering FD Rx-7 EWP System - Lite Kit - No Pump or LCD Controler

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 the reliability 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 system is designed to work with the OEM thermostat, as engines running without one will run too cold( even with pump activated to keep temps near OEM levels). One will need to use a small hose to bypass the OEM thermostat near warm up activation( route one of the OEM barbs that goes to the thermowax system to the thermostat extension housing, or radiator, or drill 2 1/8" holes in the OEM thermostat as Davies Craig recommends) 

This kit uses the OEM FD3S water pump housing and oem thermostat(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 air pump. Air pump removal not required if using a different length belt.
