Default 05 STi new setup IAG stage 2 & gtx3076r

So long story short, I purchased my first STi a couple weeks ago (05 metallic grey 44k miles). It has the following mods:
- ATP gt30r .63 rotated kit
- Turbo port matched with down pipe, down pipe wrapped and sprayed with dei paint
- Precision fmic custom piping*
- Tial 38 mm wastegate
- HKS carbon ti exhaust
- Dual HKS bov
- Dual Moroso catch cans
- Apexi turbo timer
- AEM wideband, defi boost, pyro, oil temp with controller
- Walbro 255 lph fuel pump
- Id1000 injectors*
- Perrin fuel rails
- AEM v2 standalone*
- Aeromotive fpr with oil gauge*
- Top feed tgv deletes w/ port matching
- Mishimoto Radiator hose
- Stage 1 phenolic spacers
- Mildly ported Built heads, stage 1 gsc cams with valve springs, retainers, lockers, guides
- Ferrea valves
- ARP headstuds
- Powder coated intake manifold - Port matched
- Beat rush pitch mount
- Tomei UEL Headers port matched and jet coated
- Heat wrapped harnesses and ac lines and p/s
- Killer b coolant reservoir and oil pickup
- ACT Stage 2 clutch
- ACT moderately lightened flywheel
- Tien coil overs ss
- STi front strut bar
- STi H brace
- Kart boy end links front and back
- HPS brake pads
- Varrstoens Es2 wheels
- Pro drive mudflaps*
- Weather tech floor mats*
- Aluminum shift ball
- Optima Red top battery
- Front lip, rear window lip, jdm rain guards
- Alcantera shift boot and ebrake boot titanium shift ball and short shifter
- Hella horns

Soooo Monday night the turbo took a shit due to leaks in the coolant & oil lines. So I decided to just build it the way I want.

My tuner/builder and I spoke about what to do and this is what we decided on. He said we could easily hit 450-475whp on 93 octane with the following set up in addition to the current mods on the car.

Will be adding:
- Grimmspeed EBCS
- IAG stage 2 block
- Garret gtx3076r turbo
- AEM 320lph fuel pump
- Killer B 4-1 holy head w/ up-pipe
- Kasey Harris tune, from Dyno Time Speedworks in Hickory, NC

I would like everyone's opinion on this setup and if there is anything additional I should add. Thanks guys & gals

Spend the money on good plumbing such as russell performance lines and fittings, it makes a difference. Adding AN fittings is a huge plus for disassembly.

Check the clutch obviously, maybe swap it out for something a bit higher.

Southbend Stage 3, Comp Clutch Stage 3, ACT XD. Lots of choices of full face before you decide going into puck clutches. All those clutches listed will hold 500ft/lbs of torque. I have the competition stage 4 6 puck on my car because I make 567wtq..otherwise I'd stick with full face for daily drive-ability. Once the clutch heats up, it's not soo bad to drive. The clutch feels identical to the OEM actually.

ACT HD disc here (420whp/380wtq) and it slips drag racing. It'll hold the LC and normal shifts or normal launch with FFS. Gets too hot launching in boost and staying in it for a full pass though. This clutch did NOT like a 2nd gear start in boost. Normal driving its great with slightly firmer pedal feel but lots of engagement feel. No issues in traffic or spirited driving through the woods, never tracked the car so can't comment on autoX or road course.

Stepping up to the HD 6 puck for this next round to prep it for E85, bigger turbo, more boost, and more forged pieces.
