The Mitsubishi 4G63t is one of the most potent engines on the sport-compact scene, and its ability to be modified to incredible power levels makes it extremely popular with performance enthusiasts.

This is the first book to focus specifically on the 4G63t engine (as opposed to the various vehicle platforms in which the engine appears), allowing much greater depth and focus on what most enthusiasts really care about—horsepower.

Written with the assistance of Robert Garcia of Road/Race Engineering, the premier Mitsubishi performance shop in the United States, it will be the definitive book on 4G63t performance.

Mitsubishi's 4G63t engine is among the most powerful engines ever in the sport-compact world. It's not uncommon to find one of these four-cylinder, iron-block, aluminum-headed, 2-liter turbocharged monsters making more than 1,000 horsepower with the right modifications and tuning—well above the 200-300 hp produced in the factory-made engines.

Bolted into such cars as the Mitsubishi Lancer Evolution, Eclipse, and Galant, and the Eagle Talon and Plymouth Laser, the 4G63t has more than a cult following among sport-compact enthusiasts, who know and respect this engine's immense performance potential at the track or on the street.

Up until now, in-depth performance information on the 4G63t has been hard to find. For this book, author Robert Bowen went straight to the source, Robert Garcia of Road/Race Engineering in Santa Fe Springs, California. RRE is the most well-known and respected Mitsubishi turbo performance shop in the United States, and Garcia is its in-house engine builder.

Mitsubishi enthusiasts will benefit from Garcia's expertise and be able to build better, stronger engines than ever before.

How to Build Max-Performance Mitsubishi 4G63t Engines covers every system and component of the engine, including the turbocharger system and engine management.

More than just a collection of tips and tricks, this book includes a complete history of the engine and its evolution, an identification guide, and advice for choosing engine components and other parts. Profiles of successful built-up engines show the reader examples of what works, and the book includes helpful guidance for choosing your own engine-building path.
