The Subaru Impreza started with humble beginnings in 1992 as an affordable and compact family car. It has been offered in a variety of trim types and styles, including wagons, coupes, and sedans, as well as turbocharged performance models called the WRX and WRX STI. The Subaru WRX and STI models have dominated the sports compact market for the past decade and a half. These compact rocket ships carry the flat-four turbocharged EJ and new FA engines in a highly refined chassis that allows these Impreza models to corner like they're on rails and on virtually any surface. But, as good as they are, there is always room for improvement. In Subaru WRX & STI 2007-Present: How to Build & Modify, entry-level, moderate, and extreme modifications are covered, so a wide range of enthusiasts will find content for their particular build. In the engine department, all relevant and pertinent modifications for both the 2.5L EJ25 series and the new 2.0L FA20 are included. The book covers suspension modifications for better handling, brake upgrades, free-flowing exhaust builds, and turbo upgrades with intercoolers. Entry-level modifications for cold-air intakes, upgraded air filters, and the exhaust system are examined, as well as custom engine mapping. Stepping up to more serious modifications and products, header and up pipe updates, turbo charger upgrades, and higher capacity injectors and pump are provided. At the extreme end of WRX performance, maximum volume turbocharger, speed density air metering, cam, heads, and rotating assembly parts upgrades are detailed, many featuring step-by-step how-to sequences to walk the builder through the process. Whether you would just like to add a little extra zip to an already capable car or build an all-out street warrior, this book will be a valuable resource to help you meet your goals.
