Default New 400 HP Build in Progress

So I'm completely new to NASIOC and it seems like there's a million forums and posts, but I'm gonna add another anyways. I'm rebuilding my 2002 WRX and I was looking to get into the AWD/ Subaru scene. Existing mods on my car include;
- Mishsimoto aluminum radiator
- HKS blow off valve
- AEM intake
- ACT clutch with modified street disk
- Prostreet flywheel
- HKS downpipe
- HKS Exhaust
- Konig Carbon fiber rims 18"

Dropped the car off yesterday and the new mods being installed are;
Built EJ257 short block
New STI crank, race ACL main and rod bearings, eagle rods, CP
pistions and rings - 8.2 comp ratio, new rear main seal and case
hardware, including assembly
Blouch TD06H-20GXT Billet 8cm^2
GrimmSpeed Ceramic Coated Uppipe
GrimmSpeed TGV deletes - with core charge
TurboXS Top Mount Intercooler
DeatschWerks Fuel Injectors Top Feed 850cc
COBB Tuning AccessPORT Subaru 2.0L Turbo
Walbro Fuel Pump 255Lph 1
Walbro Installation Kit Subaru WRX / STI 2002-2007
Kelford Cams
Perrin crank pulley
BG lowering springs 1 1/2"

Car will be initially tuned to 300WHP until I can get the drivetrain up to par. The plan is to eventually get 360whp - 380whp on 93 and over 400 on racegas.
Anybody have any other reccomendations of what I should do while she's apart?????

You're not going to hit your goal on 93 alone. And no head work?

Depends on the type of dyno plus the ambient conditions - temperature, atmospheric pressure, humidity, etc.

OP: To save your drivetrain, don't be concerned with WHP... only be concerned with TORQUE.

You should consider upgrading your fuel system with nicer lines and rails. I would also start saving for a 6spd or enough money to build your current trans.

400HP at the crank should be no problem

Now the real question, being in CA, how are you going to tune for 93oct? It's 91, and mixing all the time or additives would be useless for a daily-driver, and you would only be down a little bit in terms of power without all the headache.

Lastly, who is doing all the work, and tuning? In San Diego there is no one worth while. In Huntingtonbeach and and LA there are some very reputable places to go to...
