I am currently looking into buying a new engine for my WRX, because i am going to attempt a twin turbo setup and i don't think the normal EJ20 can handle two turbos. So, what do you guys thing i should do, should i buy the EJ25 from http://www.xcceleration.com/engine-packages-raceengines.html

...where it costs $4599 for the EJ25 short block or should i go with cobb, which costs almost around the same i believe?

Sheese. Another engine builder.. One thing makes me wonder though.. they have builds that produce 640hp on pump gas.....for 21,999 which doesnt include a 6000 core charge....

640 ON PUMP GAS?????

If they built 350 chevy Vette motors, they would get .. say 1400hp on pump gas... think about that one for a minute....
