Subaru’s third-generation STI platform was released in the model year 2008 but was initially available only in the 5-door wagon configuration. This lack of choices had many Subaru enthusiasts holding off on purchases until the release of the GVB-coded sedan in 2011. With a few minor facelift and aero enhancements, the 2011-and-up STI models retained the same 2.5-liter EJ257 turbocharged boxer engine with its factory-rated 305 HP power output. The only notable difference between Gen 3A and Gen 3B STIs, outside of the availability of both the sedan and wagon platforms, was Subaru’s switch to a full-synthetic engine oil straight…

In this day and age of “there’s an app for that,” it is sometimes hard to “wow” someone with new technology. Instead of an “oh my God” reaction, a “that’s pretty cool” response is usually an indicator of something quite innovative. AEM Electronics is hoping for an “oh my God” reaction to its latest engine management system. The AEM Infinity-10 EMS puts leading-edge motorsports-technology engine management into a new platform for PnP high-performance enthusiasts.

In our first Test & Tune with the K20Z3-based Honda Civic Si, we managed to bump up the power production with an overall 12.6 peak whp gained, with sections of the powerband showing increases as much as 19.1 whp. These power increases were realized with basic bolt-on products and an engine-refreshing upgrade to synthetic oil. For this round of parts, we decided to turn our attention to the area in and around the cylinder head to see if a few more aggressive bolt-ons could add power to our naturally-aspirated coupe.

The eighth generation Honda Civic represents a legacy that dates back to the early 70’s. What started as an economy car evolved into the leader of the import tuning revolution of the early 90’s. Even though Subaru’s STI, Mitsubishi’s Evolution and Nissan’s Z have become exceptionally popular in the sport compact segment, an army of Honda loyalists continue to support the Civic banner, and Honda continues to answer with the Si.

Nothing can put the brakes on a project quicker than a FROZEN nut or bolt. Aside from being a massive frustration, seized hardware can lead you to demolish perfectly good tools or bust a knuckle or two. While there is no one method that will work on each and every situation, there are a few procedures that have proven effective in the past. Here’s a quick look at some knuckle-saving techniques. Text and Photos by Robert Choo Public Enemy #1 Make no mistake; rust and other types of metal oxidation are your enemy. Unfortunately, the underside of a car is…

How refreshing it is to have our Project EVO in the magazine for two consecutive issues. Things rarely go as planned in the world of magazine project cars, but last month things finally started to come together for our Project EVO. To top it off, we finally managed to get over the 300-wheel-horsepower hurdle on XS Engineering’s 4WD dyno. Text and Photos by Michael Ferrara In the beginning of our Project EVO, we had outlined breaking our buildup into three distinct levels of tune. Level One would seek to maximize power with the factory turbocharger. Level Two would look for…

It’s been four issues since we last visited our Project EVO. During this time, the EVO has been involved in one of our most time consuming product evaluations of all time. This evaluation consisted of testing nearly every available exhaust system for the EVO. If you are interested in the results, be sure to pick up the June/July 2004 issue of our sister publication TPR.

For the second month in a row, our STi earned a bye-run in competing against our EVO-VIII. The EVO-VIII has been involved with one of our most-extensive exhaust tests that will appear in our sister publication Tuner Performance Reports (TPR). Text by Michael Ferrara // Photos by Phil Lam As we set out from the start, our buildups will attempt to achieve peak reliable performance in three different configurations. Our first level will involve the parts and tuning that will help us achieve maximum performance from the stock engine and turbo combination. Our next level will attempt to achieve peak…

For our ongoing battle betweeen STi and EVO-VIII, we were planning on having another round of upgrades for both vehicles. However, things don’t always go as planned in the world of magazines. For this issue, our STi earned a bye-run when our EVO-VIII had to be racked for a clutch upgrade.

Our first level will involve the parts and tuning that will help us achieve maximum performance from the stock engine…

What’s better… Subaru STi or EVO VIII? Both are great cars with tremendous potential for additional power and performance. Over the next year or two, we hope to provide some additional insight to this question by showing the performance potential of each vehicle.

Our first level will involve the parts and tuning that will help us achieve maximum performance from the stock engine and turbo combination. Our next level will attempt to achieve peak performance…

One of the hottest cars for the tuner market is arguably the Mitsubishi Lancer Evolution VIII. Its high-output turbocharged four-cylinder engine and all-wheel-drive configuration make it an ideal platform for performance upgrades. In our September issue, we demonstrated some of the performance potential of this vehicle when we evaluated the Buschur Racing Stage 1 performance package. Since that article, we’ve been fortunate to get another EVO-VIII in our stable of performance vehicles. With this EVO, it will be our goal to show case the entire HKS performance parts lineup for the EVO-VIII as we gain first-hand product knowledge and direct…
