Camshafts in Subaru WRX
The Subaru WRX has two camshafts. The EJ257 Dual AVCS 2008+ cams feature the same successful lobe designs used on the earlier engines. The Dual AVCS on this engine is a great tool for the tuner to provide a greater operating range. Easily identified by the triggers on the rear of the cams.
The information from the search results indicates that the Subaru WRX has two camshafts, and this is consistent with general knowledge about the engine configuration of the Subaru WRX.

Which is faster DOHC or SOHC?
To sum it up, a 4 Valve per cylinder SOHC engine with a lighter valvetrain mass would have better performance characteristics at the lower end of the powerband. However, at higher engine speeds, a DOHC setup with its higher valvetrain mass and as many valves per cylinder will develop higher peak torque and horsepower.
Is the Subaru WRX rare?
The Subaru Impreza WRX STI 22B is one of the rarest creations from the company, a special two-door version developed during its successful run in the WRC in the mid-1990s. The company only built 425 globally and just five examples arrived in Australia – and this is one of them.
What engine has 4 camshafts?
A V engine or flat engine requires four camshafts to function as a DOHC engine, since having two camshafts in total would result in only a single camshaft per cylinder bank for these engine layouts.
What engines have 2 camshafts?
In an inline engine, there is one camshaft in the head and in a V-engine, there is one per cylinder block or two camshafts. In this layout, the cam operates the valves directly in a simpler design than the pushrod designs for multivalve heads.
Is SOHC faster than DOHC?
DOHC engines have better airflow, more power, and higher speed than SOHC due to increased fuel-air mixture intake and release, resulting in greater horsepower.
Do you have to run 93 in a WRX?
The WRX STI, on the other hand, requires 93 octane. Even so, the Owner’s Manual says that if this grade of fuel isn’t available in your area, 91 octane is acceptable. The WRX, WRX STI and BRZ also have decals inside the fuel lid spelling out fuel requirements.
Can you cam a Subaru WRX?
Cams DO work on a Subaru, and they work VERY well.
How many camshafts does a car have?
Most current OHC engines have dual camshafts; one operates the intake valves and the other the exhaust valves. On a V-type engine, such as a V-6 or V-8, or a horizontally opposed engine, such as those used by Subaru, each cylinder bank has two camshafts, so there are four in total.
Can you make a Subaru WRX faster?
The cold air intake replaces the OEM air filter and housing system with a larger, smoother intake duct and a high-flow filter that allows more air to enter the engine. This increased airflow increases the engine’s power and efficiency, resulting in faster acceleration and improved fuel economy.
Is the WRX DOHC or SOHC?
2.0 liter 4 cyl DOHC turbocharged engine w/ 268 hp and 258 lb-ft torque [WRX]
