Story:
I first got my Aspen white 06 STI when I was returning to the states after serving in Korea for 2 years. I reenlisted in the Army in Apr. 06'. I got $12,500, after taxes, for a bonus. That's where my jouney for mods began.

My mod list with my bonus consisted of all my defi gauges/controller and center gauge pod, my Pioneer head unit. intake, fmic, dp w/ custom exhaust, walbro 255 and the utec. It was only road tuned so I don't know the power numbers for those mods. I do know that it was really rich, pushing 21psi and would have HUGE backfires and get horrible boost creep.

I drove it like that for about 8 months then got deployed x-mas 2006. I married my girlfriend and we had our son while I was home on mid-tour leave. I think all I got was my a-pillar gauge pod and some exhaust hangers. I had to take care of the family and furniture for a home I was to return to instead of the barracks.

Taxes came back in 2008 and I got my hood from a buddy who was going to trade in his 07 wrx for an 05 STI. I got some headers for my bday and made 270whp/276wtq only running a 13.1 @ 103mph. That was enough to fry my clutch. I opted to upgrade to the ACT HD clutch and streetlite flywheel while at it. I deployed a second time around X-mas 2008. I ordered some PE850cc injectors and my Tial sport Q bov.

I came back from that deployment X-mas time 2009 and shortly after ordered a Full Race twin scroll hta gt3076r 1.06 a/r turbo kit and my KSTech 83mm cold air intake. On the stock block, that setup made 380/364 on a mustang dyno. My fastest time on that setup was a 12.20 @ 115mph.

I left for Germany in June 2010, leaving the car behind. In Sept I found out my dad had put my car in the shop shortly after I left. With a fully built long block it now makes 436/426 (mustang) on 93oct @ 24psi and 499/468 @ 28psi on VP MS109.

I finally got my car to Germany in Sept 2011. I got on the Nurburgring and roasted my stock brakes after 1 lap in the Spring of 2012. I finally got my brakes upgraded in September 2012 with DBA rotors and Project Mu pads and went back to the Ring in Spring 2013. I did 5 laps there with some great videos (too large for youtube).

I am now at Fort Polk Louisiana and am registered in the SCCA and have completed my first autox, placing 1st in SM against 2 other cars in my class and had the fastest fendered car out of 35 others
Went to my 2nd event 27 Apr and took 1st place again in SM. 3rd event on May 18th I got 2nd. I lost to a widebody STI with 295 slicks. I also got a hard pipe to replace the big silicone section of the turbo inlet.

June 6th I went back to Cobb to get the car's tune finished. After the first power pull they shut the car off so I walked over to it. They started it back up and we all distinctively heard the rod knock
I rented a Uhaul truck and trailer to get it home 5hrs away. I yanked the motor and disassebled it for the first time
I found rod 3 bearing destroyed and rebuilt the engine. I got everything installed and fired up the day before the movers came to pack everything for my next PCS to Ft. Bragg, NC. Perfect timing!

I started my break-in miles and noticed the oil leak. Took me a few reinstalls to realize I was using the wrong o ring. Fixed the leak and put about 40 miles on it and the cam bolt broke, causing the timing belt to come off. I threw in the towel and sent the car to Subaru to have them fix it. After 2 months, I finally got my car back and have installed a ton of little items that I've had and some that I've received for Xmas.

In April of 2015, I recieved my first sponsorship from Virtue Motorsports and have started a "shop" from home which I named, Car Addict Motorsports. In May, my new engine suffered a catastophic engine failure due to a lean tune that turned my entire longblock into scrap metal. I finished paying off that engine in December 2015 and have began building another, stronger, motor.

In May of 2016, the build is almost complete thanks to Virtue still being on board and recieved a sponsorship by Clutch Masters to help get everything back together by way of a twin disk clutch. I also got my engine parts back from the machine shop to start assembling everything.

January 2020, I finally had the car issue free and got it to the tuner. Waited to hear some good power numbers but turned out they had boost control issues. They couldn't fully diagnose it since the engine spun another bearing on the dyno. I could have bought another car at this point with how many engine I've gone through :/ Engine 5 going in at 85k miles. Out of owning this car for 14 years, I've only been able to drive it for 5!

July 2021 its all put back together with some new upgrades; Koyo radiator, Aluminati expansion tank, custom 6an fuel lines mated to an Aeromotive FPR.

Kartboy front and rear shifter bushings were ordered and have arrived, will have to wait to get home on leave from Iraq in July to install them. Can't wait to feel the difference.

Re: 06 STI...ready for an ATP 3076R!!!

ya i've asked a few buddies (personal tuners) and they said that it seems like it was a tune for high compression or meth tune...cuz of my afr's, 12:1 all the way to redline. they said it needs to be more like 11-11.5, so my tuner could have easily turned the boost up a litte from 18.5 to say 21 and made over 300, not too sure why he didnt though :( here is a link to a discussion about it. (i kinda jacked the thread after people mentioned all the on-topic options) http://www.iwsti.com/forums/texas/147776-other-places-tune.html

Don't you get more lag with that FMIC rolling vf39? Hmmmmmmmmmm....

What unit you in? Former Devil Dog here, oohrah! :p Get some Army doggie!

Re: 06 STI...ready for an ATP 3076R!!!

If he can beat 1599 SHIPPED, then I'm all on it. Already, well halfway linked up with a "dealer" (lisensed). A friend of a guy I met in Missouri. Just a guy "to help fellow subie owners get parts without getting raped":)
^^No difference in "lag" going to a fmic, maybe slightly less throttle response.

Tim, dont forget this site for your turbo. He'll give you a great deal, tell him your military. Adrenalin Rush LLC

Re: 06 STI...ready for an ATP 3076R!!!

More piping for the air to move through, it takes the air like .10032 seconds to travel with a tmic and .12005 or something with the usuall fmic. Its posted in one of the threads I follow on nasioc. To get more actual lag you would need a larger exhaust housing.



Yeah Tim, I garrantee he can beat that. Hes ex military and a good buddy of mine.

Re: 06 STI...almost ready for an ATP 3076R!!!

The SMC kit finally arrived today. I will be using the trunk reservoir so idk what imma do with the 04/05 windshield washer reservoir.





All I need now is the turbo/ewg/dump tube and the inlet. I will be getting a cold air intake since I've heard the Injen intake wont be sufficient.
