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


These are in stock.

Lite kit includes ewp blanking plate & oem gasket only. This is for customers who already own an ewp pump/controller. 


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

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 airpump. Airpump removal not required if using a different length belt. 

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.
