A long bore engine, as the name suggests, has a longer cylinder. These engines reach their peak torque at a lower rpm when compared to a short-stroke engine. These are more efficient engines and are moreover used in commercially selling cars.
Does boring an engine increase compression?
All of these components have a direct affect on compression. For example, as the bore becomes larger, compression increases. If you use heads with a smaller combustion chamber, the compression will increase. Even changing to a thinner head gasket will increase the compression ratio.
How do I know if my cylinder needs a honing?
Simply deglaze the cylinder with hot water and SOS pads to thoroughly clean it, and then look inside. If you can still see the original hone marks (cross-hatching) then you likely will not need to hone the cylinder.
