I'm pretty sure, it's somewhere around 330-350ish (at the wheel)

WRX blocks are semi-closed so if you want really power you should find a full closed block like 2.2 blocks or the STI blocks-- I am not sure but the WRX tranny probably won't be able to handle the torque though you probably have to go with a STI 6spd or an RA or PPG gear set

WRX and STi blocks are both semi-closed decks, whether it be a EJ205, EJ207, EJ255, or EJ257. The EJ205/7 share the same block, just the internals are different (ie pistons, conn rods, crank) as with the EJ255/7.

To add onto that as well, the RA will not reliably hold 330-350 whp. It's the same material as the stock gears, just different ratios. A 6 speed, PPG set, and MFactory will all hold that. Albeit, the PPG and 6 speed will hold much better than the MFactory, however, it has and is possible to do.

GL though. You have to keep in mind that from the inception of the STi thru 2005 (IIRC, maybe 2007) they used the JDM EJ207 and got the same hp as the USDM EJ257.
