The Brian Crower K20Z3 stroker kit for the Honda Civic Si incorporates a 102mm stroke. The Brian Crower stroker kit will increase displacement in your K20Z3 up to 2.35L with an 92mm cylinder bore, ideal for maximizing torque output in the Civic Si. Brian Crower's K20Z3 stroker kit utilizes heavy duty premium steel billet connecting rods. Also included in the Brian Crower K20Z3 stroker kit are custom CP forged pistons, carbon steel alloy wrist pins, full ring pack and buttons. Brian Crower's Pro Series K20Z3 rods are rated up to 600 maximum horsepower. Not only will a Brian Crower K20Z3 Stroker Kit give your Civic Si more displacement, it will also improve the strength of your bottom end, allowing you to run high boost levels without worry. Please note that this is not a do-it-yourself project, it will require removal and re-installation of the engine and all of its major components (timing belt, oil pump, etc.) In addition, the block must be machined, cleaned, and bored to 92mm to fit the new components. Expect to spend around $1500 on machine shop labor, plus whatever the installation and removal expenses may be.
