BULL BOOST K-Series FG2/FA5 T3 .82 Turbo Manifold Kit (Civic Si 06–11 / K20 / K24 Swap)

Part Number: 723098228322

Built for real performance, the BULL BOOST K-Series Ramhorn Turbo Kit is engineered for fast spool, strong midrange torque, and consistent top-end power for serious K-swap builds. Designed specifically for the Honda Civic Si, this setup is ideal for street, drag, and track applications.

Built for Response. Built for Power.

The ramhorn bottom-mount design is optimized to bring large turbo response into a usable powerband, delivering strong midrange pull while maintaining top-end horsepower potential. This makes it a solid choice for aggressive street builds and competition setups.

Constructed from 304 stainless steel with thick schedule 40 (8-gauge) piping, this manifold is designed to handle extreme heat and high boost without cracking or warping. A CNC-machined 1/2” thick flange ensures a strong, leak-free seal under pressure.

The fully ported, low-angle merge collector improves exhaust flow efficiency, helping reduce spool time and increase overall turbo performance.
