EJ25 Stage 1

P2P EJ20 Stage 1

Product information

Description

Our Stage 1 EJ20 motor is the most popular 2.0L motor and the largest value to be had in the market. Many racers purchase these engines for track use or replacement JDM style OE 2.0 liters. The cases start as EJ205 open decked cases. The cases are then closed decked and the mains are pinned. The closed deck inserts used on this engine are a single piece billet design that is far stronger than a sleeved motor, or a semi-closed deck block. This creates a far superior EJ2.0L than anything provided on the market. As always, the bores are match-honed to each piston, the main bore is perfectly align honed, and the engine is fully assembled and blueprinted to exacting specifications. Just because this is our entry level motor, doesn’t mean we don’t spend the same amount of time perfecting the geometry and creating a truly balanced and blueprinted motor. Our goal is to provide the customer, you, with entry to a level of engine building normally found in super cars and race teams. Our goal is your success, we are not afraid of any problem, and will assist you with any questions.
