The dood's build. Pair of built motors? 1.5in wheel poke?

Greetings MSO bros and hoes.
I'm embarrassed to see that I've only posted once since moving to the new forum... Shoutbox too convenient!
Proud owner and member of community since 2012 with a 2012 in Black Mica. "Got-Mota?" on the old forum (good riddance). Shoutout to Nator OR.

Current humble mods:

I went off on black Friday sales and dug myself in deep.

In hand about to install:
CS intake mani + exhaust mani
CST5 ball bearing turbo
Bosch Id1050x injectors
Split Second controller
N2Mb Wotbox
CS lower tie bar
CS tmm insert

Still shopping but most likely settled on:
CS aux fuel kit + tank
CS 3.5in DP
Cobb 3in catback (yes, the quiet one - I'm not 16 and don't really need more exhaust noise, I prefer spool sounds. Besides, the local straight piped vq35 crew has already made me go deaf)

The plan is to bolt up as is and run 400/380ish while I build a motor on the side with 700hp headroom (it will be the first I've done).
The car currently has only 65k miles and the stock bottom end is really healthy so should easily survive 6 mo. to a year of 400/380. I will then swap in the built motor and start building the stock motor so I have a pair to swap as needed and can really BEAT THE SHIT without reservation. The goal once built with the new turbo setup is obviously 500/500 for a while until I find myself moving to a new turbo. I will be doing some head work and valvesprings in both cases to allow for at least 8k rpm redline.

I have a good friend who owns a body+paint shop and we are discussing doing flares like a few others have done with the goal of adding 1.5in of width per wheel (17x9.5 +18 to maintain stock inner clearance).
If we settle on this I will snag the wheels right away and rock it with 1.5inch poke for a while cause why the fuck not.
Willtheyfit.com is great for testing fitment btw.
I'll post some pics later of some goodies - car is basically stock appearance wise besides being debadged with blacked out Ms.

Helpful suggestions, insight and trash talk are all much appreciated especially when the virgin engine build process begins. Thanks for taking a look!
