Default Does anyone know if an '03 WRX oilpan will work on a 2.5???

Have one of these lying around and wondering if this will work on a 2.5l engine.
It is off of an '03 ej20, and I want to know if it will work with an ej25.

Please help me out as I can't find the part #'s for this online.

Thanks,
Bruce

I have an 02 wrx with a 2.5 block in it, I'm using the original oil pan from ej20. However if you want to put the STI headers on you will have to get the STI oil pan.

someone wanted to put this oil pan on their STi, so they would be using stock STi headers on their engine, so I guess that it won't fit. Thanks for the info.

It fits, but you have to use the complete oil pan assembly with the oil pickup. The only sti headers that DO NOT FIT are the JDM v8 sti headers. The usdm's are the same exact as the usdm wrxs

How does changing out the oil pan from the 2.5 to the 2.0 oil pan effect amount of oil needed?

Just went from an 03 2.0 pan to an sti pan. The markings on the dipstick are different although it takes the same amount of oil. The oil sits at a different level in the pan due to the depth/shape. You could make new markings on the old stick but I just got a new one. The only other thing that's different is the oil pickup. The wrx pan can't accommodate equal length headers so also be aware of that. Some people change the dipstick tube but I'm pretty sure they're the exact same thing.

The wrx pans hold more oil, if I remember correctly 4.8 in a wrx in and 4.3 in an sti. Yes you have to use the oil pick up and windage tray to match the pan or if physically wont fit. You all need the dip stick to match the pan.
