Engine oil is very important for EJ20 turbocharged and perhaps for The natural way aspirated. Surely you don’t want problems with the engine, so use large-top quality primary engine oil.
Improved Effectiveness: Permits ideal airflow, that's vital for protecting engine electrical power and responsiveness.
A five-velocity guide came normal during the MY01 WRX but a 4-velocity car might be optioned for the MY02 WRX. Electricity output across the MY01 and MY02 WRX is 160kW and there’s 292Nm of torque (at 5600 and 3600 rpm respectively).
Corrosion Avoidance: The proper coolant mix inhibits rust and corrosion which will damage the engine.
In its most simple In a natural way aspirated sort, the EJ20 generates approximately 150 horsepower. However, when turbocharged and intercooled in types similar to the WRX STI, it might generate upwards of 300 horsepower.
Normal Maintenance: Sustain with normal routine maintenance schedules, like oil changes and air filter replacements.

Engines could be discovered by coil on plug with one M8 bolt per coil and valve covers with 4CAM 16VALVE and horizontal strains above the plug holes. Typically these engines all provide the slanted intercooler. Engines within the STI RAs acquired the upgraded Shim-Below-bucket fashion lifters unlike the traditional HLA buckets the WRX & the WRX STI had.
Yet another difficulty that should be addressed will be the extreme oil consumption from the EJ20, Particularly the turbocharged ones, and can have an affect on small dimensions of In a natural way aspirated engines.
During its many years of manufacturing, the EJ20 has identified its way into the engine bays of several of Subaru’s most noteworthy types, starting to be synonymous with dependability and possible for electricity. This engine has demonstrated its flexibility through the rally phases to your day-to-day commute.
The facility steering pump is different. The JDM cars and trucks incorporated some Spec C with 13:1 steering rack. The pump remained exactly the same, so it really is created to manage a quick rack.
With appropriate tuning and modifications, the EJ20’s horsepower can be noticeably increased, which makes it a favorite for fans seeking to extract more electricity from their engines.
The whole WRX array benefited with the MY97 engine update but, again, the wagon version isn’t as grunty because the sedan. Even with employing a nine:one static compression ratio, the manual and vehicle trans MY97 wagon tends to make 176kW/304Nm. In late 1997 (for your MY98), the wagon’s output was bumped approximately 184kW/306Nm. Then, in late ’ninety eight (to the MY99), the WRX sedan engine was boosted to 338Nm. A revised intercooler Main, revised consumption manifold and ECU mods may be thanked for your get.
