Engine Age: Substantial-mileage engines may well take pleasure in a little thicker oil to compensate for amplified clearances due to don.
Enhanced Overall performance: Allows for exceptional airflow, which can be vital for sustaining engine electricity and responsiveness.
A 5-velocity manual came conventional inside the MY01 WRX but a 4-velocity auto may be optioned for the MY02 WRX. Electricity output through the MY01 and MY02 WRX is 160kW and there’s 292Nm of torque (at 5600 and 3600 rpm respectively).
Turbocharger Troubles: The turbo can fail as a result of oil starvation or abnormal exhaust temperatures on turbocharged styles.
These EJ20Gs might be recognized via a tab on the ideal floor in the block half in addition to a smoother surface area. The EJ20G ongoing being the main engine in the WRX wagon by having an automatic transmission from 1996 right until 1998; then, it had been changed from the EJ205.

Making use of an upgrade ECU and totally free-flow exhaust, output is increased to 175kW (a achieve of 8kW above the base WRX). The WRP10 goes to the history guides for possessing the strongest EJ20 turbo engine in an Australian-spec WRX; the MY06 design uses a 2.five-litre engine. Inside the STi vary, Australia initially acquired the MY99 Edition five two-doorway and MY00 Edition six four-door types. These engines retain the Japanese-spec mechanicals but are detuned to accommodate Australian gasoline – so precise output might be under the claimed 206kW/353Nm.
Idle Instability: This can be due to a defective idle air here Regulate valve, vacuum leaks, or soiled fuel injectors.
The open deck block on all EJ20G may be determined by a smoother floor, plus a tab on the best surface area from the block halves. The EJ20G ongoing to be used in the WRX Wagon with an Automated Transmission from 1996 till 1998 when it absolutely was replaced by the EJ205.
I feel all of us can nod our heads that every one engines are certainly not best – far from staying there. But even with that, we want to continue to keep our devices in good managing situation and extend their useful daily life.
There’s just 155kW/270Nm rather than 176kW/304Nm. The MY97 WRX update (with a very new inlet procedure and several other improvements) maintains the exact same 155kW electric power output but delivers it down from 6000 to 5600 rpm. Peak torque can also be enhanced to 290Nm at 4000 rpm. Even more alterations for the MY99 WRX bring power as many as 160kW and, for The very first time, an vehicle Model was obtainable. The handbook and automobile WRXs have equivalent engine output.
These camshafts are belt-pushed and. The ingestion valve diameter is 36 mm, as well as exhaust valve diameter registers at 32 mm. The spark plugs are positioned centrally for superior combustion from the chamber.
Perfect for reduced to mid RPM ranges and torque-dominated functionality, this engine is considered for use in certain apps in drifting, race tracks, and even drag racing. It's also an excellent engine swap for fanatics who want to taste the savory crisp of the EJ20 engine.
