If you did full bolt ons (upgraded intercooler, inlets, dual cone filter intakes, downpipes) and run a small mix of e85 like 30% you should hit about 440whp with 93 octane mixed.
Breaking 500whp on stock turbos will require higher content of e85, upgraded fuel pump and/or meth injection and a custom tune. But your stock turbos will hate you since you'll be pushing them beyond 21psi.

my friends stock turbos are at 27 psi and taper to 21 at redline
mine have been at 21.5 for a couple years now and they are fine.
