GReddy Turbo Kit
GReddy Turbo Kit is designed to enhance the performance of your Honda Civic Si EP3 (K20A) vehicle. It is engineered to provide increased power and efficiency, while maintaining reliability. Here are some key features and benefits of this kit:
- Improved power and torque output: The turbocharger helps to increase the air pressure entering the engine, resulting in a significant boost in power and torque.
- Enhanced throttle response: The turbocharger's design reduces turbo lag, providing quicker throttle response and improved acceleration.
- Increased fuel efficiency: The turbocharger utilizes exhaust gases to power its operation, reducing the load on the engine and potentially improving fuel efficiency under certain driving conditions.

Important !
Make sure the all the wire connections are correct. If they are connected incorrectly, it can damage the e-Manage and/or the ECU.
(5) Reinstall the ECU back in its place, and secure the e-Manage next to the ECU.
* Avoid mounting the e-Manage unit in the area that would be exposed to direct sun light, mo isture, or near heater outlet
3-15 Starting the Engine
(1) Refill the engine oil to factory spec.
(2) Check all the hoses and wires ne then recon nect the n egative sid e of the battery.
(3) Tun the ignition to “ON” positio 3 get fuel pressure. Then, check the injectors and the fuel rail for any fuel leaks.
* Repair any fuel leaks before starting the engine. Starting the engine with a
fuel leak can cause fire in the engin e compartme nt and can be very dangerous.
(4) Remove the ECM fuse and cra nk the engin e to get oil pre ssure to the turbo.
(Until the oil light on the dash turns off) Check for any oil leaks, then reinstall the fuse and start the engine.
(5) While idling, check for any oil, coolant, or air leeks.
(6) After inspection, reinstall the under cover and other stock parts that was remove d. setting. This turbo kit is preset to boost between 0.6kg/cm
2 e turbo-actuator to 0.5kg/cm
2
.
It is very important that you monitor the boost pressure, and make sure not to over boost. Over boosting can cause engine damage.
This completes the Turbo Kit installation.
Important!
• It is very important that you monitor the boost pressure, and make sure
not to over boost. Over boosting can cause engine damage.
• GReddy Performance Products, Inc. is not responsible for any engine
damage caused by over boosting (increased boost), modification to the kit, and/or misuse of the product. NO WARRANTY is offered.
• Due to lack of control over proper installation and use of this product,

e-manage Information
Important!
•
The e-manage included in this kit is preprogrammed for the this turbo kit.
•
Do not attempt to adjust any of the setting in the e-manage.
• If any adjustment made can cause damage to the e-manage, engine and
the factory ECU.
Important!
As of 5/25/03 this kit is not a street legal kit. Please ignore the label on the
e-manage.
ACTIVE L.E.D.
• When the ignition is turned on
, it will illumin ate and flash GREEN.
• When it reaches to the A.A.V. setting RPM range, it will illuminate and flash
ORANGE.
•
When an error is detected it will flash RED.
INTE
•
RACTION L.E.D.
This will illuminate when there is a connection with PC.
Ch ecking Error Codes
When the unit is powered up and if there are any errors, the ACTIVE L.E.D will turn “RED” from “GREEN”, and begin to flash.
If this happens shut the engine off and turn the ignition switch to “ON” position to go to Self Troubleshooting Mode. While in the Self
Troubleshooting Mode, the L.E.D. will show the error code. Turn off the ignition. Check the error code in the chart below and fix the problem. The error code will show until the error is corrected.
