FRESHLY BLUEPRINTED AND ASSEMBLED BY IAG
The IAG Stage 3 Extreme FA20 DIT Closed Deck Short Block starts with brand new OEM Subaru WRX case halves and takes it through their in-house closed deck conversion process. This utilizes top-of-the-line tools such as a Haas VF-4SS CNC mill to prep for the IAG closed deck inserts, cut O-ring receiver grooves, and drill and tap for 1/2" head studs. All of this provides a motor designed to greatly reduce head gasket failure during high cylinder pressure scenarios. The block then goes on their Sunnen SV-30 for the best bore and hone available.
