CT Engineering Supercharger Kit Description
NEW: We now offer discounted "No Reflash" versions of the CT Supercharger Kits and Upgrade Kits for customers who want to tune their ECU using a different method, such as the Hondata FlashPro. Keep in mind this option will void the CT warranty and any CARB exemption status.

This CT Engineering (formerly Comptech USA) is one of the best power modifications you can make to your 06+ Civic Si. This product was designed from the ground up with quality, reliability, and durability in mind, and the installation is simple and completely bolt-on (no extra modifications or engine upgrades are required). Not only that, but this supercharger kit comes complete with a CT/Hondata Reflash, which will ensure that your ECU is tuned perfectly for your new supercharger right out of the box. Best of all, this 06+ Si supercharger kit is CARB Certified (Stage 1 only) for street use in California! That means if you live in California, you can still legally pass smog tests with this kit installed.

Please note that after purchasing this kit, you will be required to send your ECU to Hondata for reflashing (unless you get one of the "No Reflash" versions). We have instructions on how to remove your stock ECU if you need them. Please also include the ECU Return Shipping Label (included in the kit) with your ECU shipment.

Key Features:
  • Adds approximately 40-50 horsepower to the wheels, so about 230 whp total on an otherwise stock 06+ Si. Adding an intake/headers/exhaust will increase this number to about 270 to 280 whp.
  • Very linear increase in boost as RPMs increase.
  • Runs at a very safe boost level of about 4-5 PSI.
  • Impressive mid-range throttle response and top-end performance.
  • Complete "bolt-on" kit, requires no other engine modifications.
  • Includes a CT/Hondata Reflash for your ECU (except for the "No Reflash" version).
  • Comes with carbon fiber fuel rail cover (see picture).
  • The addition of intake, headers, and cat-back exhaust is highly recommended.
  • CARB Certified for street use in California (Stage 1 kit only)!
  • Extremely detailed and thorough installation instructions.
  • Installation time is only about 8 hours.
  • Even includes Denso Iridium 1 step colder spark plugs!
Stage 2 Upgrade: The Stage 2 upgrade for this supercharger can be purchased in both Stage 2 and Stage 2 Plus versions. The Stage 2 uses a 3.3" pulley instead of the standard 3.6" pulley used in the Stage 1 kit, and provides about 20 whp more than the standard Stage 1 kit and about 3 PSI more boost pressure (varies with modifications). The Stage 2 Plus uses an even smaller 3.15" pulley to provide about 4 PSI more boost pressures (again, varies with modifications), and 30 whp more power than the Stage 1 kit. The Stage 2 and Stage 2 Plus upgrades are also available to be purchased with any brand new CT Supercharger Kit at a discounted price compared to what you would pay if you bought the Stage 1 Kit first, and then upgraded to a Stage 2 option later on.

Stage 2 Upgrade Detailed Information:
  • With an upgraded intake, headers, and exhaust, you will see 290 to 310 whp, or about 320 to 340 flywheel horsepower!
  • Comes with 4 high performance injectors and a new CT Supercharger pulley (3.3" for Stage 2 and 3.15" for Stage 2 plus).
  • Injectors are factory Honda injectors modified to flow 520cc (compared to 310cc stock).
  • Injectors are flow benched and matched in sets for each specific kit.
  • Injectors are also completely "drop-in" and require no wire harness modification or fuel rail spacers.
  • Includes a special CT/Hondata ECU Reflash which enables your ECU to take advantage of the larger injectors and higher boost. This Reflash will work seamlessly with Stage 1 (3.6"), Stage 2 (3.3") and Stage 2 Plus (3.15") pulleys. This means you can swap out to a different pulley to lower or raise your boost level without having to send your ECU back to Hondata!
  • The special CT/Hondata ECU Reflash will also raise your rev limiter to 8500 RPM, and will lower your VTEC window to 3200 RPM (VTEC will only engage at that RPM if you are at full throttle).
  • REQUIRES USE OF AN AFTERMARKET INTAKE DUE TO INCREASED VACUUM LEVELS (your stock intake will collapse under the pressure). We recommend using the CT Engineering intake system.
  • Not CARB approved, and not emissions legal for use on public roads.
  • Voids the warranty on your CT Supercharger Kit.
  • For the Stage 2 upgrade kits, you must already a CT Stage 1 Supercharger kit, and a BLOWER SERIAL # IS REQUIRED BEFORE WE CAN SHIP YOUR PRODUCT (we will ask you for this after the order is placed or you can put this information in the order notes when ordering online). If you purchase any Stage 2 Full Supercharger Kit, then a blower serial # is not needed.

Optional Parts: To maximize power with this supercharger, we definitely recommend getting an intake, headers, and full cat-back exhaust system.

Other Recommendations: Please only use premium fuel (91 octane or better).
