Evo 7 build help

Hello, I've got some questions regarding my current/upcoming build. Most likely about realistic power estimate and about choosing remaining parts to get the project finished.
Current specs:
Wiseco HD .5 oversize 9.0:1 pistons
Manley H-tuff rods
Stock crankshaft
ARP bolts
Stock head and cams
Garrett gt3582r with t4 flange and manifold

Need to buy:
Injectors (1000cc bosh ev14?)
Fuel pump (walbro 450lph?)
Intercooler (600x300x76?)
Wastegate (manifold has 50mm v-band flange)
Clutch

What can I except with the turbo and stock head or does it even work well preferably with pump gas (98)? Closest e85 stations are 60km from home so wouldn't want to drive that much only to refill with the 40 litres fuel tank. I was about to get cams but I'm really on budget atm. and would like to get the car back on road this summer after 2 years of waiting.
Any recommended clutch? Preferably budget friendly for excepted power without sacrificing much in drivability and maybe with room for cams which I'll probably get later?
Does my head bottleneck much and how much more can I except with something like gsc s2 cams and porting it? Budget friendly improvements to my build are also welcome.

Thank you in advance.

Nice build list!

I've seen guys on stock turbos making 300-350HP with reasonable boost levels. If you decide to go a "budget build" I'd do an Evo 9 turbo

As for cams I'd go with HKS or GSC cams, best recomendation I'd give for a clutch is an Excedy twin
