First published in 1989 as Tuning New Generation Engines, this best-selling book has been fully updated to include the latest developments in four-stroke engine technology in the era of pollution controls, unleaded and low-lead petrol, and electronic management systems. It explains in non-technical language how modern engines can be modified for road and club competition use, with the emphasis on power and economy, and how electronic management systems and emission controls work.


Four stroke engines have entered a new era; an era of pollution controls, unleaded and low lead fuel, and electronic engine management systems. For the engine and car enthusiast the situation may appear perplexing and confusing, in fact some engine tuners pine for the “good old days”. They feel that high performance and engine tinkering is now on the way out. This couldn’t be further from the truth; performance is here. Modern engines offer a greater potential for performance and economy than those of previous times.

Today’s engines feature better cylinder heads with large valves, and port and combustion chamber designs far superior to those available in the past. Many feature fuel injection, along with high How inlet and exhaust manifolds. Ignition systems able to provide precisely timed combustion for more power and efficiency. Lightweight, but stronger pistons, connecting rods and crankshafts which give greater reliability and allow higher rpm. Small turbos and sophisticated management systems have allowed high power outputs without turbo lag. The list could go on, for from whatever aspect present day engines are examined, the irrefutable conclusion has to be that these engines provide a fine base for performance-oriented development.

In this book I have set out to show the enthusiast how electronic controls and emission controls work, and how current engines can be modified for performance with cam, exhaust and carburation changes, and still pass emission inspections in those lands with such requirements. The end result is a book which I believe outlines in a non-technical manner simple and inexpensive tuning modifications for road and occasional club competition engines, with the emphasis on economy and useable street power. I am sure that you will find this publication an informative and valuable tuning aid.
