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

You should be able to hit 300 to the crank with a few add-ons. Stock injectors I believe are in the ball park of 450cc, so on paper at about 80% duty cycle, you should be able to make about 350 on them. I'd suggest that at the bare minimum to send your turbo off for a re-fresh. Radium Auto makes a pretty badass fuel tank/cell. I think Scott is running one in his Celica.

I'm probably about 3 steps away from going full retard on my 2nd gen 3S build. lol

-Billet CT20B turbo from TurboBay
-ATS adjustable cam gears
-GSC valve stems seals
-GSC S1 Cams
-GSC Valve Springs
-1ZZFE Shimless buckets
-Devil's Own Meth injection
-Megasquirt PnP
-TiAL QR BOV
-3" exhaust
-Southbend Stage 2 Endurance on an S54

and some other tidbits. I'm a fuel pump and a set of injectors away from going Flex Fuel/E85.

I'm tempted to hit the junk yard to pull a 5SFE for the block, but trying not to put anymore money into than I already have. lol
