Default Is the automatic in a 1999 2.5rs the 4EAT used in the auto wrx's? Can i toss a ej20

Hey everyone....i am looking to make a daily driver 2.5rs . I want a automatic for sure and found a nice 2.5rs auto (1999) . I am curious if i can toss a ebay ej20 turbo motor into the car with that tranny wiht a few mods and be quick and reliable? They are the same bolt pattern setup right?

Yeah the motor will bolt up to it.

In your subject you ask if the 4EAT's are same. No the RS does not have the same 4EAT as the WRX does.

well is the RS's 4eat at least as strong if not the same? I know the final drive is different. Could i pump 300hp through it if not a bit more...like the wrx guys do?

I don't know how "strong" it is, but I think 300 hp is doable. Big things to remember is a tranny cooler and good synthetic fluid.
