Having proper crankcase ventilation is critical on a performance engine, especially forced induction ones that have more blowby past the rings by nature. The pressure needs to be relieved. Excessive crankcase pressure can blow seals, cause severe smoking from the turbo and affect piston ring seal causing smoking and losing power.

Our STI has been driving around as a daily for two years now with all of the typical bolt ons. It has been reliable at 318 whp with good driveability and fuel economy on regular pump gas, in other words a hassle free car that is very easy to live with. Of course if good was enough, more is better and we could not leave good enough alone.

You may have heard the expression 10 lbs of shit in a a 5 lb bag before. Well I am fairly certain the origination of that statement came from the first person to try and remove the intake manifold from an EJ25 and work on the systems surrounding and underneath! In our quest for more power and greater reliability we dive into the bowels (the heart would be the engine) of the boxer motor to upgrade our fuel system, improve the intake and intercooler efficiency and well… To reduce the amount of useless crap tucked in to the engine bay.

It's single digit temperatures outside and the car is under the knife for a HUGE round of modifications! It doesn't run, we have gotten 14" of snow in the last 48 hours and what are we doing? Why using our daily driver to tow it out of the garage to shoot pictures of our new goodies from Weds Wheels, Progress Suspension, Go Fast Bits, and Kartboy. We risk frost bite to bring you this latest installment of Project Gen3 STi, luckily for you the Internet is warm.

As much as we like fast cars and sano builds here at MotoIQ we also love tech gadgets! Messing with cameras, microphones, cell phones, instatwittergrambook uploads; all of these things are what we do on a daily basis to bring MotoIQ to the masses. It should go without saying that when new items hit the market that offer us the ability to do those things in a more efficient manner, our pointy nerd ears perk up and our fingers buzz the web in search of said future altering technical goodness. In this case the gadget of mention is the Igloo case for the iPhone. Click on is as we put the case through its paces…

Project Gen 3 STi: Suspension upgrade with M7
by Wes Dumalski
When last we left off with Project Gen 3 STi we were enjoying the power and up to this point the only modifications we had done so far were to make the car go faster. It was time to change that as the GR STi is a bit soft around the middle. Our friends at M7 came to our rescue with their Super Street Performance Coilover setup. We were eager to put this new suspension through its paces to see what type of performance it really offered so step inside and read all about it.

Project Gen 3 STi - Impressions of the Turbosmart IWG75 and BPV
By Wes Dumalski
"Hey Bro, do you want to test some Turbosmart stuff?" The quoted text is from none other than Martin G from MotoIQ headquarters asking me if I would like to play with any Turbosmart products on our GR STi project. With this project still in the early and mild stages I first scratched my head wondering what I would be able to use and test. When I think Turbosmart I envision huge external wastegates on race cars and e-boost setups. Initially I wondered exactly what I could even use on the STi... Not wanting to miss an opportunity I perused their site and used their vehicle specific search feature to see what they had available.

Project GD STI - Checking Out The Development of KW's New 3-Way Adjustable Clubsport Coilovers
By Mike Kojima
A few months ago we visited KW Suspensions' factory in Germany to learn about the development of their new 3-way adjustable Clubsport coilovers. We feel that the 3-way Clubsport is a pivotal product for KW. It promises the flexibility in tuning of expensive elite Motorsports only shocks that are priced out of reach of most enthusiasts in a package that is 50% less than the custom uber dampers.

Project GD STI- Improving the Fuel System with Injector Dynamics and Other Details
By Mike Kojima
When we had last left off on Project STI's engine, we had just upgraded the cooling system in anticipation of another round of tuning. What was supposed to be just some routine installation of a few parts to get a little more power ended up being something a lot more complicated, time consuming and involved.

Project GD STI- Getting it Slowed Down with Stoptech
By Mike Kojima
The Subaru GD STI comes with pretty good brakes from the factory, big Brembo 4 piston front and 2 piston rear calipers squeeze big vented rotors. In other words the stock brakes are already quite good, what would have been state of the art just a few years ago. This means we would have to be careful when it comes to modding them, it is easy to mess things up and actually do worse than stock with a poorly engineered brake upgrade. So why would we want to change them out with something else? The main reason is that since our car is going to see some occasional track use, we want to upgrade our brakes so we can drive our car to the track for an event without the hassle of having to switch pads at the track. The big brakes will allow us to run at speed on a streetable brake pad. Bigger more powerful brakes will also be easier to modulate. The third reason is admittedly that big brakes just plain look cool! We went with Stoptech as the brake system of choice for their combination of daily driveability and track performance. We selected Stoptech's Trophy STR big brake kit.
