Getting 300hp out of an st205 3sgte reliably? Options

[Wannabesupra]

So I'm gonna be doing some work to my st205 swapped Celica over the winter and I'm wondering how much I'd be spending to make 300hp reliably (I'm running a fwd setup). Can this be done on the stock turbo? I've heard they're unstable over 18psi. And would 300fwhp be attainable with the stock fuel system? I'm likely gonna upgrade to a fuel cell since my gas tank is leaking so I'll probably have to run a different fuel pump anyways. I'm also considering a mild cam to help up the power as well. I'm thinking about going with an aftermarket ecu as well but I imagine that would set me back quite a bit money wise. Any input would be much appreciated, I'd like to see what all you 3sgte guys are running on your builds! Thanks

Yes should be easy, ideally get a good intake setup, 3'' exhaust system, alloy radiator, lag the charger cooler, and a ebc you should easily see that, i have a st205, and made 152kw atw on 15psi, now i have link ecu g4+ and all the support mods should see easy 180kw atws !!
