In 1981, production of Triumph’s TR range of sports cars came to a close. But few engineers would have considered the longevity of the vehicles. Fifty years later, the earliest models are still going strong, thanks to robust construction, enthusiastic owners and an active aftermarket spares and component trade.

Because TR owners tend to expect their cars to keep their sports car performance, and keeping a TR on the road is not an easy task, Roger Williams wrote this book, now in its second edition, as a companion to his series on how to restore the TRs. Williams is aware that even basic modern sedans have improved so much that the TR’s original performance may no longer seem so sporty.

However, with help from the TR aftermarket industry and tips from this book, performance can be enhanced. Williams aims to relate what is available to what you want to achieve, with advice for either racing, touring or everyday uses. Every page of this manual is illustrated with clear, color photos of the parts you will be dealing with – in isolation and in situ – and are numbered and fully integrated into the text.

The book discusses the pros and cons of various aftermarket products and their alternatives. Chapters run through all vehicle components, and range from your initial checks through chassis, running gear and brakes, electrics and ignition systems, fuel injection, body and trim to engine transplants. This new edition includes digitally-controlled and electronic equipment as well.

This revised edition of a book first published in 2003, provides plenty of advice for owners of all the six-cylinder TR models on how to improve their car in various ways, including for competition use as well as for the road.

It's backed up by well over 400 color photographs to illustrate the text in detail, and the section headings give an idea of how comprehensive the coverage is. From rear drive durability, to computer ignition management and improved cockpit ventilation, to engine transplants, there doesn't seem to be much Williams hasn't covered, based on his own practical experience and the input of a number of marque specialists.

If you want to improve the performance, handling, comfort or reliability of a TR5/6, you're likely to find what you want in here.
