Project Blue Boxer - Part 2: Exhaust, Brakes, Wheels, Tires, and More Tuning

It's fun to tune the car right out of the box and it certainly feels much better than stock with more boost and a little more aggressive ECU mapping (for more about this, check out our Part 1 blog here).  Our problem remains, though, that the stock components have such a low performance ceiling.  The catalytic converters are extremely restrictive and the exhaust piping is small in diameter.  This prevents the turbo from pushing further, as well as the cylinder from clearing and allowing you to advance timing and allow more air to move into the cylinder.  The wheels are bulky and heavy and for being as small as they are, they certainly don't correspond with any weight advantage.  After taking the car to the track with the completely stock suspension, brakes, and all season tires (which was really just to create a baseline, we knew we weren't going very fast without upgrading all this), it was clear that there was a huge amount of improvement to gain from a few basic upgrades.

How to Plan a 2015+ WRX FA20DIT Build

So you have just purchased your dream car and you are now looking to make it your own. Where do you start? Where do you go? What are you going to do? You need to sit down come up with a goal, prioritize, plan, and then realize your goals. This is something that is both very easy, and very difficult at the same time.

What Blow Off Valve Should I Run?

If you are a car guy, specifically a car guy with a turbocharged vehicle, and you spend any time at all on the internet, you have either asked the question at some point yourself and/or seen someone ask the question many times. There is no better way to light yourself an E-fire than to ask this question in a public forum. However, there are so many opinions running rampant all over the net, that I don’t really blame people for asking this simple question anymore. There is no definitive answer. So the best way to answer this question is to explain a bit better about the different types of valves so that you can make an informed decision.

Understanding a Dyno Graph.  Peak Numbers Aren’t the Whole Story…

One of the most common misconceptions about a vehicle is that the car with the higher horsepower will be the faster car. In my early days as an automotive enthusiast (high school), I too, was very guilty of perpetuating this stereotype. I didn’t understand much about cars back then and because of The Fast and the Furious, all I really knew was that I wanted to put blue underglow on my 1995 F150 so I could be cool too. My friends and I would sit around bench racing different cars based on how much horsepower the internet said they make and in some cases, based on which one had the highest number on the speedometer. Needless to say, my 1995 F150 with a top speedo reading of 85mph always lost, but that is neither here nor there.

When Is A Turbo Too Big?

Believe it or not, you can have a turbo that is too big… Well, perhaps too big is the wrong way to word it. You can have a big turbo that is not matched properly with your engine or even matched properly with itself (size of hotside vs compressor). While this isn’t really an issue for big v8’s or even v6’s really, the problems from this phenomena will be most evident on small displacement turbo 4 cylinders.

Project Blue Boxer - Part 1: Tuning

Our 2013 Subaru WRX sedan was purchased used in completely stock condition.  It originally had about 13,000 miles on it so it was very fresh and ready to accept some modifications.  Our approach with this project is different than what we've done before.  To be frank, we're not interested in pushing this car to the limit which is different than what we typically like to do (take, for example, our fragmented, blown engine block in our Ford Focus ST as a result of pushing the limits too far).  Our WRX was bought with the intention of educating our WRX customers, EJ25 enthusiasts specifically, and anyone else interested.

When Do You Need A Bigger Intake?

On a turbocharged car, the intake is often sized according to the stock turbo from the factory. It will be designed to dampen noise, and fit with relative ease into a certain area of the engine bay. This comes before performance and this is why upgraded intakes are such a huge benefit to making power on a turbocharged car. Smoother tubing with a high flow filter will reduce restriction and make less work for your turbo. However, sometimes even these upgraded stock replacement intakes are not enough.

FA20DIT EGR Delete - What and Why

In order to understand why you don’t want EGR, it is best to first understand exactly what it is. EGR stands for Exhaust Gas Recirculation. It's the process of pumping exhaust gases back through the engine in order to chemically reduce the displacement and improve fuel efficiency and emissions.

The Magic of E85

E85 is no longer a new thing. It has been around a while now but only in the last 8 to 10 years has it really started catching on as a form of race gas. The intended purpose of ethanol based fuels was not for race car, but it has been morphed into that due to its seemingly endless capabilities as a race fuel.

5 Exhaust System Features To Consider

Depending on who you talk to about an upgraded cat back exhaust, some will tell you it is absolutely necessary and others will tell you it isn’t necessary at all. As for me personally, I’m all about reducing back pressure. The easier it is to move air out, the easier it is to get air in… And then you can’t beat the added enjoyment you get from the improved sound, and I don’t think anyone will argue that. So what should you be looking for when picking an upgraded exhaust for your car?
