Default injector sizes (outside size not flow)

Looking for larger injectors to swap for my '05 2.5 RS. If I'm correct the RS and WRX both have top feed injectors and the STI has side feed. My question is are the injectors for the RS and WRX the same physical size. I realize the WRX injectors and going to flow more (which is what I'm looking for) but will they fit correctly where the stock RS injectors go? I figure replaceing the injectors with WRX ones will be cheaper than trying to have my RS injectors rebuilt so they flow more. Does anybody have any measurements of these injectors?

They should be the same. Top feed are top feed and side feed are side feed. I am almost certian that they will work. To confirm this you may want to look over at www.rs25.com . There will likely be more information on this subject there.
