This is a race-ready closed deck EJ short block for builds that are well beyond the basic forged setup. It is meant to live with more boost, better sealing, and more abuse.

  • Power rating: 950 BHP
  • Block style: Closed deck EJ25
  • Sealing support: 14mm head stud and Fire-Lock compatible build path
  • Best use: High horsepower drag, time attack, and serious competition-oriented EJ builds

Why you'd choose it: Choose this when the goal is big power and you want a short block that is built around stronger sealing and more aggressive use.
