This is the exact shortblock powering Unity's own "UNITY SI R" build, putting down 411 whp and 348 wtq with supporting engine mods — we've run this package for over a year and stand behind it as the right foundation for anyone pushing their L15B7 past stock limits.

Every MAPerformance engine is inspected, cleaned, blueprinted, and assembled in a sterile room, with machining scrutinized against MAP's own proprietary specifications rather than generic tolerances. Whether you're building a spirited street car or an all-out track build, this shortblock is assembled to handle it.
