2-3 Week TURNAROUND
Honda's open deck blocks are notorious for cracking sleeves at high power levels. CSS is an affordable way to build a reliable, high horsepower street engine.
CSS is a process by which the block is machined and the cylinder walls are reinforced using CSS's proprietary process that converts an open deck honda engine to a closed deck engine for maximum reliability.
CSS blocks alleviate the worries of sinking sleeves, they do not distort the main caps like sleeves can, and they do not heat soak like sleeves can.
We recommend CSS for cars aiming to make 500-700HP. For 700+, we recommend the High HP w/ O-Rings.
