There was a fairly large discussion on this recently. Try doing a search. I think Simon from Prodrive stated that anything over 280hp in stock form will cause problems. A fully tuned motor is capable of more, but there is no set MAX hp limit. After a certain amount of power, your performance becomes hampered by other mechanical items such as axles, transmissions, etc.

That is the Tony Rigoli Performance WRX that just recently ran a 10.04 1/4mi.

[EDIT] I forgot to mention that this WRX is stroked to ~2.2L

How would the max output of the Ej22T compare to the 20 if it had the RS or some other head?

That's a tough quesiton to answer since people are always finding new ways to generate hp.

I guess if you wanted MAX hp, then find a thermodynamics book, look up the Otto Cycle and fill in the variables and solve for work output. This would be the MAX hp you can make with the engine, which in the real world will be less due to things like friction. With infinite money and technology, you should get close to this number.

I think MRT has a car pumping about 450 hp from the EJ20. Don't quote me on this though.
