What Turbo to upgrade to? (2.5 using 91 octane)
So I have a friend with a mostly stock STi wanting to upgrade his vf39.
His end goal is 300-315 whp (its his daily driver as well).
He already knows he will need turbo, fuel pump, injectors and a tune.
DOES NOT WANT run meth or E85.
There are lots of threads about this but using 93 octane or E85, couldnt really find any set ups using 91.
Cliff note:
So whats the best 91 octane turbo upgrade on a daily driver to reach 300-315 whp?

I had TD06 20G 8cm with supporting mods (drop in filter, turbo inlet, injectors, pump, Spearco TMIC, turbo back) making a safe 310whp/310wtq (GST's mustang dyno) on 91 octane at 20 psi tapering down to 18 toward redline. This was on a 2006 WRX TR.
uuummm 315/335 wheel or crank horse power?
