Show original supplier description
The IAG Stage 2 2.5L Subaru Short Block is engineered for modified EJ25 Subaru engines that require a robust foundation to handle increased cylinder pressures from higher boost levels. This performance short block starts with a standard 99.5mm bore size. Precise case halves are required to be line honed together to ensure accuracy during the build process. This component is specifically designed for modified EJ25 Subaru engines. Its purpose is to provide a stronger short block capable of supporting the enhanced performance and increased cylinder pressures that come with performance modifications and added boost.
