This 2006 WRB STI was brought in needing an engine rebuild due to broken ring lands. The owner made the decision to go bigger and specifically wanted a custom one-off setup, not an off the shelf kit. Here are the specs:  

Body and Appearance:

Seibon Carbon vented hood

APR splitter

Cobb lowering springs 

Upper camber plates

SPT upper strut brace

Engine:

Mahle Pistons

Scat rods

ARP Head studs

Cometic Head Gaskets

Cosworth Bearings

Cosworth Oil windage plate

Kelford "B" Cams

ACT Clutch

Dual-catch can setup

Fuel System:

Aeromotive fuel rails

Aeromotive AFPR

Custom hard lines for fuel system

Quick Disconnect fuel lines

1000cc Injectors

Walbro 255 fuel pump

Electronics:

AEM EMS, tuned by Don Walker

5-bar map sensor

AEM Wideband

AEM Tru-boost boost controller

Turbokit:

Custom rotated kit built by HRD

Turbonetics GTK 500 turbo

Turbosmart Ultra-gate WG

Custom Stainless Steel FMIC plumbing built by HRD

Synapse BOV

Blacked out ATS FMIC core

4" Aluminum intake

AEM DRI-FLOW Air Filter

Custom 4"Stainless Steel Exhaust built by HRD

Vibrant 4" muffler

Here we see the custom built fuel system using Aeromotive Rails and AN hardlines.

These are the quick disconnects for the fuel system- just unplug and go, no spilled fuel, no mess.

This is a pretty good shot of the AFPR mounted along with the intercooler piping, turbo, and intake.

And here we see the relocated coolant pressure tank, fabricated coolant lines and 4"intake. It took some time to get the right "factory" look. The aluminum mount was made in-house and while it weighs pretty much nothing is very strong, uses the factory mounting holes and looks like it belongs there.
