Nothing too exciting, stock bottom end NEO with new bearings/spool crank collar/spool oil pump gears (so I can rev the tits out of it). Crank will be balanced too.

Basic head work, one of Tao's prototype SAT turbos. I'm aiming all in by 4k, and 420~440kW.

I think his new setup has ringlands on the pistons.

The plan was to keep it stock looking and make as much power as possible with -5s because it will be a weekend car, Then when I get over the power I'll go single turbo.

But picking a cam for both set ups seems nearly impossible.

Damn! That will be an expensive exercise! 

Why not do it once and do it right? 

Keep the boost down on the single then turn up the wick when you get bored of the power?

Do you have the 5s already?

What sort of single will you be looking at? How much power do you want? RPM limit? Where do you want you power to be? 

How long do you plan on keeping the -5's?

I already have the 5s, just need to make dump pipes,
it should not be too expensive of an exercise, i am welder/fabricator, so basically my time and bolt ons.

I was thinking something like a gtx35
if i go single 500kw anything close would be good, i think i have high exceptions tho.
would like to be safe as possible also. 8000 rpm

Has your head been relieved for a high lift lobe?

What springsdo you have and are you willing to change them?

And that's my next topic !
I would like to build a head

What's is a minimum requirement for 500kw

[33GTRV]

I did 500 with a basic home port job, valve springs and drop in cams. Took some boost tho.

What do they relive in the head for high lift lobes ?

[iruvyouskyrine]

Around the cam lobe where the lobe would otherwise contact the head from it being so big. They use head relief in conjunction with a smaller base circle I believe

[Griffin]

Hand relief in a circular motion? With lubricant or dry?
