Kraftwerks Supercharger Kit - 2012-2015 Honda Civic Si (K24Z7)
Want to make 330 horsepower from your 9th gen Civic Si without dealing with turbo lag? The Kraftwerks supercharger kit puts serious power on tap with a linear power curve that builds smoothly from idle to redline. This is a complete bolt-on kit that includes everything you need: the Rotrex C30-94 supercharger, Grams 1000cc fuel injectors, high flow intake manifold, front mount intercooler, all the piping, and all the hardware. It keeps your factory A/C and accessories, so you don't have to delete anything. When paired with a Skunk2 header and exhaust, this kit makes 330 horsepower and 240 lb-ft of torque with instant throttle response and smooth power delivery all the way to redline.
Rotrex C30-94 Supercharger
The Rotrex C30-94 uses a traction drive system instead of gears, so it runs quieter and more efficiently than traditional superchargers. It's compact, spins to high RPM without beating itself up, and stays cooler under load. The supercharger has its own self-contained oiling system, so you don't have to tap into your engine oil. This keeps the supercharger at the right temperature and reduces intake air temps, which lowers the risk of detonation and helps your engine stay reliable even when you're making big power.
Linear Power Curve
This kit gives you a smooth, linear power curve instead of the sharp spikes you get from turbo setups. Boost comes on early and builds progressively, so the car feels like a high revving naturally aspirated engine with way more torque. You don't get hit with a wall of boost that lights up the tires or upsets the chassis. The power is predictable and easy to manage, which makes the car faster and more fun to drive.
Complete Bolt-On Kit
This kit includes everything you need to install the supercharger on your 9th gen Civic Si. You get the Rotrex C30-94 supercharger, Grams Performance 1000cc fuel injectors, high flow cast aluminum intake manifold, front mount intercooler, aluminum intercooler piping, oil cooler, recirculating bypass valve, battery relocation kit, and all the CNC machined brackets and hardware. The kit is designed to work with your factory A/C and accessories, so you don't have to delete anything to make it fit. If you've got basic hand tools and a lift, you can install this kit yourself over a weekend.
Grams 1000cc Fuel Injectors Included
The kit comes with Grams Performance 1000cc high impedance fuel injectors. These are the fuel injectors you need to support the extra power the supercharger makes. You don't have to source injectors separately or guess which ones to buy. They're included and sized correctly for the kit.
Tuning Required
This kit does not include tuning. You need a Hondata FlashPro or Ktuner to tune your Civic Si after installing the supercharger. Get a proper custom tune from a professional tuner to dial in your specific setup and make sure everything is safe. Do not just install the supercharger and drive the car without tuning it.
Upgraded Clutch Highly Recommended
Your stock clutch probably won't hold 330 horsepower and 240 lb-ft of torque for very long. Plan on upgrading your clutch if you're installing this kit. An Exedy stage 2 or similar clutch should handle the power without slipping.
