The Subaru WRX was first released in 1994 with a 155kw turbocharged EJ20 which revolutionised the motorsports industry.
Australia has received the EJ20 and EJ25 WRX engines, whereas some overseas markets only have access to the EJ20 engines.
From late 2005, the WRX was sold with an EJ25; this engine introduced a more efficient boost curve along with earlier power delivery. The turbo EJ25 engine is widely recognised as having inherent ring land failures which lead to premature engine failure. To remedy this, All Drive Subaru has introduced a piston machining revision process which eliminates the issue and provides reliability and engine longevity. As of 2015, new Subaru WRX models were released with the FA20 DIT engine. While not as strong as the original EJ20 engines, they’re assembled to accommodate high compression applications and supply almost instant power on demand.
All Drive Subaroo offers a range of performance engines custom built to suit your individual application; whether you’re after a reliable standard replacement engine for daily driving, or an engine to support 500kw of aggressive drag races, ADS can design the perfect engine to suit your needs.
ADS technicians don’t rebuild WRX engines to standard specifications as they have several inherent issues we’ve solved through our revision processes. For the permanent fix, we offer our revised block internals, including Low Oil Consumption pistons and rings, in all of our rebuilt engines.
We offer 3 Levels in standard WRX replacement engines; as well as closed deck Cosworth and Tomei forged engines for high power applications. All drive Subaroo build the most robust and reliable EJ20, EJ25 and FA20 engines in the market today.
One of the key features of our reconditioned engines is our revision process. Over the last 26 years, we’ve established our own remanufacturing techniques to counter factory inherent weaknesses associated with particular models. This means that regardless of the build level, every ADS engine is assembled with our latest superseded parts and assembly procedures.
When deciding which engine is suitable for your application, you can select either a rebuilt, reconditioned or remanufactured engine assembly. The purpose of our 3 separate build levels is to accommodate for every individual budget we can; our basic rebuilt level 1 WRX engine still boasts the same warranty terms as a brand new STI short block assembly purchased from Subaru.
Whichever build level you choose, it’ll be assembled with the highest quality components and installed by the best technicians in the country.
