MAX PWR from an EJ205???

I am interested to find out what the maximum HP from an internally stock EJ205 from a 99 WRX impreza can withstand and at what Boost levels?? (above 18psi)

I recently dyno tuned my 99 WRX Impreza and it made an easy 295kw ATW on 18psi (98 oct fuel)..!!
I am running;
High mount Garrett GT35 turbo
40mm wastegate
3" turbo back exhaust w/custom exh. manifold/extractors
650cc injectors and custom fuel rail
Walbro fuel pump and Fuel press reg.
Autronics computer
Front mount intercooler
Type 3 BOV
plus afew other bits.

I have everything i need for good power figures but i am uncertain to what limit i can push my engine with all stock internals. If i was to 'get more out of it' what would be my next step? As in swapping intake manifold, heads, etc with STI components??

Any help would be greatly appreciated...!!
