Turblown Engineering FC Rx-7 EWP System - Lite kit - No pump or LCD controller

These are in stock 

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:

1. No more cavitation like the OEM water pump
2. 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)
3. Ability to control pump flow based on coolant temperature
4. LCD PWM controller allows cockpit access to coolant temperature and Alarms
5. Post shut down, engine off coolant control- eliminating heat soak of engine and turbocharger
   
6. 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 theromstat as Davies Craig recommends) 

This Street kit uses the OEM FC3S waterpump housing( S4 & S5). 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. The belt is also designed for an FD alternator upgrade( OEM alternator is too low of amp output for this kit). This kit also retains the function of the OEM thermostat for proper warm up operation. 


 If you have a 20B engine you will need to bolt on a FC waterpump housing and thermostat neck.  Please note that note that not ALL of  the bolt holes will be used, as the S4 & S5 waterpump bolt patterns are slightly different, we use one plate to fit both. 


The TurboSmart Time Attack Rx-7 has been running a Davies Craig EWP & Controller for over 5 years at no less than 500rwhp. The pump and controller are a proven system. 

 This kit does require an upgraded alternator of at least 100 amps( like the FD unit, if using FD alternator you will also need the FD eccentric shaft pulley).
