Are Subaru EJ clutch interchangeable?
I don’t know which are which right now but they are not all interchangeable. For instance, the WRX, STI and the 2.5RS all have different clutches. It really depends on the tranny more than the engine. It’s hard to say without knowing your year but The N/A Impreza’s and Legacy’s had the same engine and tranny from the early 90’s till pretty much now so if you stick with one or the other it should work. I would check out RS25.com for better info on this. They will know.
