This would be your best bet
The 2.0 litre motors can hold a lot more power than the 2.5 in stock form
There is absolutely no way in hell a stock ej255 turbo motor will hold 300-350kw at the wheels
To get to this level you will at a minimum need to put some decent headstuds in there, piss off the wafer based standard bearings, and have the bottom end balanced.
As Matt said, anything over 300 on a semi closed deck block (which the ej255 or 257 are), should be sleeved and close decked.
Sleeving cannot just be done in isolation. There is a lot involved and a proper rebuild like this with labour and parts and supporting mods to get you to 350 atw reliably will cost you at least $15,000 absolute minimum
Do lots and lots of reading and triple check before you go into something
If you want my advice, buy a turbo car, it'll be Better for you
Good luck
