Default Whats the most power made on a stock block US ej20 you have ever heard of?

I'm curious as to how much abuse a stock WRX engine could take with a large turbo, supporting fuel mods, tuning etc. and of course with a 6spd transmission.

about 1000 whp, for a few seconds.... then boom!

seriously you need to be a lot more specific with the question. Rule of thumb,
The more power you put through it the shorter the lifespan.
stock ej20 USDM blocks have a nasty tendancy to spin bearings even with stock or lightly modified setups (all it takes is one mis-shift) I wouldn't push the block too much without some internal work. all said and done, a fully built one with all the bolt on goodies and a 6 speed. I wouldnt' be surprised to see high 300 numbers, maybe 400's if you accept the lag.
Read all the FAQ's and sticky's, search search and search again, and build the car for your purposes... not what some idiot on here says is cool.
