So, not to sound like the idiot new guy (which I am), but what mods would be needed to get 450 whp out of this turbo in a build 2.0l on 93 octane?

What does built mean?

450 on 93 would be doable with every bolt on possible.
The hardest thing to do with this turbo is controlling boost and setting the waste gate properly.

It will be going on a 2.0 built block stock head with gsc s2 cams. Also going on the car will be pte 880cc injectors, spoolinup cop, o2 dump, licp, 3" short route uicp, 3.5" intercooler, forge rs bov. Going to run my 103 octane xylene mix, shooting for 30-32 psi.

Already on the car, 3port grimspeed, 4 bar map, 3 inch full exhaust, walbro 255, headstuds, some other stuff.

I really want 450-500whp. We will see..

(edit: also trying out the S90 74mm Throttle Body)
I think you will need bigger injectors for sure. With the right size injector you should be able to run 34 psi on that 103 mix.
You'll be around 480 I'm guessing. That 11.5 will be a little Laggier on the 2.0 though guessing full boost around 51-5300

I apologize for my lack of clarity. I have a fully forged bottom end. A stock head running GSC S2 and Kiggley Beehives and retainers. 1150cc injectors, licp, 3.5" ic, O2 dump. Currently running a manual boost controller, but will most likely upgrade.

You'll make 450 with that setup on 93 for sure.

Quickly? No. You'll prob have to email kinugawa. I did see a thread a few weeks ago with some for sale.

With the 2 bar fully preloaded I could only get 30#

It's just a maguyver way if adding spring tension lol. You did get the billet waste gate right?

With the 2 bar spring you should be able to get 26. But this turbo won't make much power at 26 I don't think.
