Description Applications
The IAG closed deck service requires you to provide your Subaru 2.5L engine case halves. After inspection of the bore and deck for trueness, IAG machines the case halves assembled together in our Haas VF-4SS CNC mill to accept the IAG CLOSED Deck Inserts that transform the block into a solid deck. The unique inserts feature small passages that allow needed coolant flow to the deck surface.

Service Includes:
  • Inspection of new or used EJ25 Subaru engine case.
  • CNC milling pockets for IAG CLOSED Deck aluminum inserts.
  • Installation of CLOSED Deck inserts.
  • IAG CNC threaded round inserts which creates additional reinforcement at the center case bolt locations.
  • Resurfacing EJ25 case half deck surfaces.

Does Not Include:
  • Bore and honing to 99.75mm or larger (Required).
  • Cleaning case of machining debris

*Other machine services such as o-ringing, line boring, bore and hone are extra.
