XR6 First Build - Feedback Requested

[BionicXR6T]

Hey everyone,

This is my first build, and I'm looking for any tips or feedback you guys might have. I have a 2006 BF XR6T currently making 350kw was bought like this looking to upgrade it and push it a bit further!
 

Here's the current plan:
 

Mods List:

• Garrett GTX35/82 HiFlow + Turbosmart 45mm gate

• 525 Fuel Pump

• BA BF 1000cc BOSCH Fuel Injectors

• Atomic Timing Chain + Billet Sprocket

• Crow Cams Ford Barra XR6 Spring Kit

• Plazmaman 800hp Intercooler (Already might upgrade to if needed 1000hp)

• Plazmaman Piping Kit

• Plazmaman Plenum Top + Standard Bottom

• Ford Barra 12mm Head Stud Kit (Plazmaman)

• Plazmaman Barra Billet Oil Pump Gears

• MLS Head Gasket + MLS Exhaust Gasket

• Transmission Upgrades (billet input + 2600/2800 high stall)

• Tailshaft Upgrade (GJ Drivelines)

• Billet Axles

• IMS Diff Hat

• Diff Truetrak (LSD)
   

Will run E85, aiming for 450+ kW do you think 450 to 500kw is possible?

Let me know if you see anything I'm missing or if there's anything I should look out for! Thanks in advance.
