The Subaru EJ20 engine, celebrated for its dependability and engineering, includes different horsepower scores based on the design and 12 months.

The EJ20 turbo engine has considering that experienced a large influence on performance scene world wide; it’s seen a few years of rally Levels of competition and it is Probably the most frequently modified engines in existence.

The EJ20X and EJ20Y are open deck engines whereby the cylinder partitions were supported in the a few and 9 o’clock positions. It came using an aluminium alloy block with 92 mm (3.

At last, these modifications enabled the 5-velocity manual Edition with the WRX sedan to reach the Japanese regulation output - 206kW. And Subaru hadn’t achieved this substantial output by sacrificing base-end torque – an impressive 329Nm is accessible one thousand rpm lessen than Beforehand (at 4000 rpm).

Building: Aluminum alloys for your engine block and heads give a solid nevertheless light-weight structure that withstands high temperatures and pressures very well.

Frequent Upkeep: Keep up with standard routine maintenance schedules, which includes oil variations and air filter replacements.

The Subaru EJ20 engine has an oil ability that varies a bit according to the specific design and year, but it really commonly holds approximately four.

This was the 1st EJ20 turbo to look in Australia with AVCS and an operational intercooler water spray process. There were no mechanical modifications in subsequent STi models until finally the introduction with the 2.5-litre engine within the MY06 STi.

Idle Instability: This can be on account of a defective idle air Management valve, vacuum leaks, or dirty gasoline injectors.

And the initial of this sort of engines will be the more info EJ20G. It is amid the primary to work with turbocharger and oil nozzles, reduced compression pistons, and a closed decked block. The potential in the inventory gasoline injector is 380 cc.

The crankcase of these engines has 5 main journals, and also the flywheel housing was cast Using the crankcase for elevated rigidity. Th EJ20X features a forged crankshaft and connecting rods with Forged aluminum pistons with forged crowns.

Employing good quality substitute pieces and adhering for the advisable provider intervals will keep your EJ20 operating effortlessly For a long time to return.

Possible for Damage: If the timing belt breaks, the engine can suffer sizeable hurt, leading to highly-priced repairs.

Your entire WRX selection benefited from your MY97 engine update but, again, the wagon Model isn’t as grunty since the sedan. Regardless of utilizing a 9:1 static compression ratio, the handbook and automobile trans MY97 wagon makes 176kW/304Nm. In late 1997 (for that MY98), the wagon’s output was bumped nearly 184kW/306Nm. Then, in late ’98 (for that MY99), the WRX sedan engine was boosted to 338Nm. A revised intercooler core, revised ingestion manifold and ECU mods may be thanked for that gain.
