How many cylinder liners do I need for an SR20 engine?

The SR20 engine typically uses four cylinders. Since these HKS cylinder liners are sold individually, you will need to purchase four units to complete the engine.

What is the main benefit of using new cylinder liners during an engine rebuild?

New cylinder liners provide a precise and smooth surface for the pistons and rings to seal against. This ensures optimal compression, better oil control, and helps prevent blow-by, contributing to improved engine performance and longevity.

Are these liners a direct replacement for the stock SR20 liners?

Yes, these HKS cylinder liners are manufactured to meet the specific requirements of the SR20 engine. They are designed to fit correctly within the engine block and work with standard SR20 pistons and rings.

Product Details

When you're rebuilding the heart of your SR20 engine, getting the cylinder walls just right is critical for performance and longevity. These HKS cylinder liners are designed to replace your worn or damaged original liners, providing a fresh, precise surface for your pistons to move within. This ensures a good seal for optimal compression and helps manage oil effectively, which is key to keeping your engine running smoothly and preventing premature wear.

HKS is known for making well-built performance parts, and these liners are no exception. They are manufactured to tight tolerances, meaning they fit right and work as intended with your SR20 engine block. This level of precision is important because even small variations can affect how well your piston rings seal against the cylinder wall. A proper seal means more power and better fuel efficiency. These liners are a solid choice when you need to restore your engine's integrity, especially if you're pushing the limits or simply want the best for your SR20 build.

When undertaking an engine rebuild, it's important to have all the necessary components ready. These liners are sold individually, so be sure to order the correct quantity for your SR20 engine, which typically requires four. Make sure to consult your service manual for the proper installation procedures and any associated hardware or sealants that may be needed to ensure a successful rebuild.
