The size of the intake valve on a Subaru can vary depending on the specific model and engine. However, based on the search results, it seems that the standard size for the intake valve on Subaru engines is 36mm . It’s important to note that this size may not apply to all Subaru engines, so it’s always best to consult the specific technical specifications for a particular Subaru model and engine.

Are intake and exhaust valves the same size?
Therefore, the intake valve is generally designed to be larger than the exhaust valve to reduce the difficulty of intake and increase the amount of intake air.
How much HP can a EJ25 hold?
300 whp:The EJ20/EJ25 engines can handle 300 whp maximum with stock internals with no further modifications other than a proper fuel management tune. 400 whp:We suggest a set of forged AMR pistons and billet rods to safely boost up the engine.
What size is the Subaru EJ25?
The Design of the EJ25 Engine
It has a displacement of 2.5 liters, which is where it gets its name. The bore and stroke of the engine are 99.5 mm and 79 mm, respectively. This configuration provides a good balance of power and efficiency, making it a popular choice for Subaru vehicles.
What is the most common intake valve seat width?
0.040-0.060 inch
Most of the machinists we spoke with prefer an intake-seat width of 0.040-0.060 inch. Narrower seats generally improve flow but are also less durable.
Are intake and exhaust valves the same?
The exhaust valve is in constant contact with exhaust gases that are at very high temperatures, so they must have a stronger structure than intake valves. The heat accumulated in the valve is released through its seat by 75%, it’s not surprising that it reaches temperatures of 800 ºC.
Are intake valves always bigger?
An inlet valve is always bigger than an exhaust valve because air is sucked in unless turbo where it is blown in. What ever, the volume allowed in by the bigger valve is critical in performance. Besides, that it is always being cooled by incoming air, so it can be larger and thinner.
What size is the intake valve?
Typically, for a 2-valve cylinder head, the intake valve head size is taken around 0.35 to 0.5 times the cylinder bore, and in case of exhaust valve, it is between 0.28 to 0.43 times the bore.
What size is the intake valve on a exhaust system?
Calculate intake and exhaust valve sizes
Note that this is for two-valve cylinder heads. For example, a 1,588 cc engine (bore of 79.5 mm and stroke of 80 mm) and a rev limit of 6,000 RPM should have a 36.43 mm intake valve and a 30.96 mm exhaust valve.
Are all air valves the same size?
It is important to understand the functions and limitations of each valve type so that valves can be located and sized properly for a pipeline. Air Release Valves are probably the best known air valve and are typically furnished in sizes ½ in. (13 mm) through 3 in. (76 mm).
