Boosted Scion tC
Here is recap of my project that is finally done and tuned. The end result end up at 298hp/265lbs.ft @ 9lbs with 91 octane on a hot Arizona day. The turbo kit and dual exhaust was designed, made and installed by Boost Flow and tuned by UMS in Arizona. Compared to TurboToyotas, this kit fits Scion tC without any modifications to the engine bay.
This is how the tC looked when I just got the car:
I started with installing Tein Super Street coilovers and Tanabe strut bar. I chose these upgrades because they give you the most value for the best price. Tein Super Street coilovers offer enough options without going overboard and of course unsurpassed quality. A Tanabe strut bar is a cheap upgrade to get that additional reinforcement at the front of the car.
Drivetrain was upgraded with ClutchMasters FX400 clutch kit with 4-puck sprung disc, plus flyweel and TRD LSD.
Then started building the kit and dual exhaust on the car. That took the most time about 2 months or so. Upgraded fuel injectors with 550cc RCs and Walbro pump. Used AEM F/IC and AEM Wideband UEGO.
here is the manifold tagged
manifold welded together
dump tube and downpipe
one more shot
building the intercooler
charge pipes
building the dual exhaust 3in turboback w/ cat
Complete layout of the turbo kit without blow-off valve attached
Here are some video I took of the car:

Later got carbon fiber lip kit installed and aftermarket hid headlights and 18in Axis wheels. I'll tell you that lip kit is no bolt on. We spent a few hours trimming to make it fit right.
Here are more vids, still not tuned though:

So far no CEL, even before putting in F/IC.

I actually like the headlights; I've got them on my own car, so that makes me completely biased. 
The IC piping, in my opinion, is brilliant. I would love to see a straight shot of the front end. It breaks up the plastic tedium of the front bumper with some huge shiny pipes connected to a huge shiny block. Awesome.

Love the wheels thinking about doing that to mine but never get to doing it....

i like almost everything about the kit except two things...
1. all the charge piping looks to be 2.5", except for the one 3" piece that goes to the throttle body, which then has to be reduced to 2.5" anyway. it seems as if its only there to fool people at first glance that all of the charge piping is 3". the only other possible reason i can think of is that the bov you are using is too big to mount on to 2.5" piping.
2. the dump tube should have a bracket welded on to fasten it to the downpipe. after about 6 months of driving, my dump tube broke off right at the flange because of how long it was, combined with all of the vibration.
...other than that im really impressed with the car and hope to see some track numbers soon. i would hate to think that a good looking kit like that is going to waste. :D
