Default 2004 WRX stage 2 + E85?

Hello. I currently have a 2004 wrx that's currently getting installed
Short ram intake
Unequal length headers
Cattles up pipe
Cattles down pipe
Cat back exhaust
Cobb boost controller
565 injectors
Walbro 255 fuel pump.

Now my question is I'm shooting for 280 WHP and wanted to know if I can go open source just on stage 2 and achieve they or am going to need to go e85 as well? Also will the stock TD04 hold 280WHP?

if you have a stock transmission, the amount of torque you'll get with e85 & a td04 might snap gears relatively quickly

if its an ots map it really depends on what the map requires doesnt it? But yes you will need at least bigger injectors id go with 1000cc and a walbro 255 pump
