Default 2.5L DOHC '99 Legacy Engine into 02 wrx

I found this engine on craigslist and ive been wanting to rebuild an engine and put it in my car. ive done some research and from what ive read this engine is not intercooled but i dont know if its turboed. would it be beneficial to put this into my car (cause it is a 2.5)? i havent found any threads that talk about putting an older engine in a newer car
thanks

a 2.5 legacy motor will be slower than your turboed 2.0. idn how the swap would go, if you want the legacy motor in there till your 2.0 is built..?? but if that whats your doing sounds like a hassle.. get another 2.0 or a 2.5 sti short block and start building that and swap for ur oem engine when its built

It's not really worth buying. There is not much from a 99 2.5 that you could use in your wrx. The heads and intake manifold are not compatible with your ECU. This is the noob section so I won't go into why, but trust me, it won't work. You could use the shortblock but the compression would be on the high side of what you'd want with a turbo. So again, really not worth buying for what you want to do with it.

from what i understand you would be better off just buying a sti short block, reusing your wrx heads...and if you decide to upgrade later you'll get more power/torque from the same mods than you would compared to your stock 2.0l.

Correct me if I'm wrong, just my .02.
