I purchased this 2005 STi from a car dealer in Cartersville, GA, just northwest of Atlanta. It had 105,000 miles. I was looking specifically for a car in excellent Shape cosmetically, mostly stock look, inside and out. I had a local shop inspect the car for any major issues. It seemed to pass general inspection, no accidents, nothing major was obvious.

I have made changes and improved almost every aspect of the cars performance. Below are the details.

Items in Black were installed when I purchased the vehicle
Items In GREEN are improvements I made

My First track day was Mid August 2012 at Mid Ohio. The car performed admirably. I did not drive very well. Still trying to get used to a 4 cylinder Turbo. Rowed the gears plenty trying to find the right gear to get out of slower corners. Over all was impressed with the handling of the STi. My skills were not even close to pushing the car to its limits. I look forward to making improvements/Upgrades to the Car but mostly improving my driving skills.

Here are a few Photos: Here with the Enkei SC03's

Hood Scoop delete was one of my first mods

After putting on some miles, I wanted to be sure the oil usage issue was not contaminating my Oil with Fuel, depleting the oil's ability to properly lubricate and protect the engine. I changed the Oil with Enoes 5w40. I put 600 miles on and 1 track day. I changed the oil again and sent the oil to Blackstone labs for oil analysis. Results came back with no fuel or anything else unusual in the oil. Next is to run 2 or 3 track days and 1500 to 2000 miles and have it checked again.

I changed out all the green lights in the interior console, to match the RED Instrument cluster. Radio, HVAC, Drivers side Window controls, Ignition ring and Cigarette lighther light ring

The oil consunption seems to be causing problems with the O2 sensor, causing computer pulsing of the engine at 3500 RPM, Like it was before. So, for my winter Project we are cracking open the engine to see what's wrong. No massive smoke and compression is good. My tuner thinks its a ring gap issue or the engine was just built loose for "future massive HP". The FP Red Turbo has been fully rebuilt so its probably not in the turbo.
We will see.
While we are in the shop I will address a small slow leak at the Drivers side Axel / transmission interface (failed gasket). Already did the other side because of a torn CV boot that came with the Purchase of the car. Can't just replace the boot, Oh No, gotta replace the whole axel with a Rebuilt unit.
New Engine mounts, (Group N) Stock ones were soft to begin with. I am assuming mine are still Stock with 110K mikes. Transmission mounts and cross member bushings too.
Install Whiteline steering rack bushings
If the Fix on the the engine isn't too expensive I'd like to replace my DC sport UEL Headder with a crack (repaired with a weld) with a Tomei EL Header with Swaintech Coating.
Last on this years List (probably Pushed to next year based on Budget) is the Whiteline ALK and new Sway bar links.

We finally got the engine pulled, looking for a reason for the oil consumption. It looks like, from the initial evaluation, the engine is clean. Not much oil getting into the cylinders. However the FP Red Turbo, Rebuilt by FP, 10,000 miles ago is totally messed up again. Loose shaft and bent fins, Lots of oil getting by the seals. We will be checking the intercooler for Oil tomorrow. So, it looks like I am getting a New Turbo, rather than a rebuilt engine. Forged Performance Rebulit the Engine in 2010. As far as we can tell, there is very little Oil getting by the piston rings, even for a Built engine.
I wanted a Faster spooling Turbo anyway, so this moves me in that direction quickly. I'm hoping to fit a few more upgrades in the Budget now with the elimination of the engine re-rebuild. We will have to wait and see how the fix and the budget pan out.

Can't afford rotation. I was considering Dom 1.5 xtr. My Tuner suggested Blouch 18G XT-r. Spool is my top priority for Road course HPDE. HP in the 375 to 400 WHP is second priority

When I upgraded the turbo, i was in the same boat.

I like road tracks (HPDEs), so spool was important.

18g, 20g, 18g, 20g, 18g, 20g, 18g, 20g...............................................

Talking with a couple of tuners they recommended the 20G. There comment was you will be disappointed with the 18G.

The 20G spools pretty quick. At this point I would not want to go to an 18G. Maybe if I was trying to shave 10ths on an autocross course.

Coming from the FP Red both maybe a disappointment to you.

See you at Grattan :)
