From the beginning of TR7 development, British Leyland saw North America as a primary destination for its new sportscar. The car was to be the first of a new line of Triumph cars that was tailored for the American markets. Launched during one of the darkest times in British Automotive History, the car was Triumph's biggest seller. The author explains in great detail how to increase the performance of these four and eight-cylinder sports cars and how to select and transplant higher-performance engines. Contents include aesthetic changes, body strengthening, roll-cages, brake upgrades, performance wheel changes, gearbox, clutch, four-cylinder engine upgrades, selecting and fitting a V8 engine, improving the suspension and upgrading the rear axle, ignition, carburetor selection and fitting, improving existing and retro-fitting Electronic Fuel Injection (EFI), engine transplants, electrical reliability upgrades, weight reduction and more. Covering the whole car with over 500 color illustrations, step-by-step instructions, 23 clear line drawings and useful club and supplier listings, this book is a must have for any TR7/8 owner.

Roger Williams was born in 1940. Aircraft was his first love but in 1986 he started his own consultancy business, which allowed him to restore numerous MGBs and to write three MGB books. He retired in 2000 and has since moved to France and written four Triumph TR restoration books.Review:

The latest addition to Veloce’s SpeedPro series of books on modifications comes this, a 208-page softback title dedicated to the last of the Triumph TR series: TR7 and TR8. And as the only book currently available that’s dedicated to improving the much-maligned TR7 family, it fills an obvious gap in the market.
Almost sixty dollars for what is basically a paperback might sound like a lot of money, but what you’re paying for here is invaluable information and expertise rather than fancy layouts or expensive looking hardback covers. This is very much a book for TR7 and 8 owners who want to get their hands dirty in their quest for getting the most from their classics.
The whole subject of modifying your TR is covered here in superb detail, with in-depth chapters dedicated to such areas as four-cylinder engine upgrades, acquiring and upgrading a Rover V8, fitting out a V8 engine bay, suspension and steering tweaks, body strengthening, transmission modifications and electrical improvements. Each chapter is broken down into separate sections too, enabling you to pinpoint the specific advice you’re after and to make the whole reference process that much easier.
Author Roger Williams is no stranger to writing no-nonsense, practical advice on upgrading MG and Triumph sports cars, and already has a number of other books in print. This, though, looks set to be one of his best-sellers so far, both here and in the USA.
No longer is the TR7 frowned upon by TR aficionados. And for those who are intent on getting the most from their 7s, this book is surely a must. It’s not cheap, but the advice it contains could save owners a lot of hassle – and cash.
New Zealand Classic Car magazine, May 2007 Review by Allan Walton
Unlike many classic cars, and largely because of its unloved status, a modified Triumph TR7 doesn't attract the ire of enthusiasts. And, while tuning the Triumph's four-cylinder engine isn't forgotten, it is perhaps not surprising that a large section of this new book is devoted to dropping a Rover V8 into BL's wedge-shaped sports car.
A good adjunct to a standard workshop manual, this book covers tuning methods and the V8 replacement via easy to follow step-by-step instructions - each step illustrated by clear photographs. It will be especially useful for those planning a V8 swap (although the author opts for the standard Tr8 engine position – which places the V8 far too forward in the engine bay. Most Kiwi TR7 specialists will recommend moving the engine further back toward the firewall, something that can be achieved relatively easily). A good book for TR7 spanner-hands looking for a few home projects to improve their car's performance, braking and handling.
Classics Monthly, May 2007 UK magazine
It's always a good sign when I pick up a book about a car I have no specialist interest in and find myself sitting down, reading and becoming absorbed. That was the case with this book. There's a lot of ground covered here from wheel styles to V8 engine transplants, brake upgrades, bodywork, chassis prep and more. Full color pictures throughout and most of the work using parts from British suppliers. Anyone with a TR wedge will find there's lots of useful info within.
Triumph Club, Ottawa, Ontario and the forthcoming edition of TR8 Car Club of America newsletter by David Huddleson
There have been many books published over the years documenting the history of the TR7 and TR8, and more recently there have been “restoration” books showing how to cut out those rusty bits. However, something that many of us have yearned for, has finally arrived. Veloce Publishing has released in the spring of 2007, a book from Roger Williams, titled “How to Improve Triumph TR7, TR7 & TR8”. Here we finally have an organized and comprehensive guide to satisfy those of us who want more from our wedge cars. Roger has delved deep into the knowledge and skills of many Triumph TR7 and TR8 specialists world-wide, and with all this information he has then explained in detail how to improve many facets of these vehicles, from engine performance, to braking and handling, wheels and tires, carburetion and fuel injection, and much more. What is impressive to me is Roger’s effort to consider different communities of wedge “improvers”. He is considerate to owners of bone-stock original cars who do not want to alter their vehicles, at least not in ways that are not reversible. Roger does press the point of safety, especially where technology has jumped ahead of what our cars were engineered with back in the 70s. As I started to say, each chapter and topic that Roger covers, does take into account different aspects of improvement. Roger addresses the improvements to what he terms “Fast Road cars”, “Ultra-fast Road cars” and “Competitive cars”. In a few of my own words, these are, first, the street cars that may participate in occasional track events such as autocross, but are driven on normal roads all the time. The second class will include highly modified cars that may still be road-worthy but may not be pleasant to drive on a 300-400 mile weekend journey. The investment into this category will be significantly higher, and the originality folks will not likely be included. Finally, the out-and-out competitive category is likely very small, but we all love to watch our cars compete on the track with Corvettes and Mazda RX7’s etc. The investment on these vehicles may be massive, with custom suspension, massive brakes and highly-tuned engines with exotic internal components. But for those of us that can dream, Roger gives enough information to make us want more. The book has been well thought out, and Roger starts with fundamentals of improving any type of automobile, as there are facets of the TR7 and TR8 that must be improved before adding massive horsepower and road speed ability. Specifically, for our cars, the braking ability has always been considered barely adequate. Roger’s chapter on braking is, to me, fantastically presented. Again, he considers those of us who want, or need to stay with 13” wheels. There are some racing classes that mandate cars to run on wheels of their original size, so racers as well as street cars needed to be considered. This was presented extremely well. And of course, beyond that, Roger whets our appetite with big ventilated brakes and exotic multi-piece racing rotors for those that just have to have them!
I could go on for pages on the aspects of cooling the engines, strengthening the body shell, and engine swaps, but I think I will leave it to you to purchase your own copy of Roger’s new book. Check out Roger’s earlier publications too, such as “How to Power Tune Rover V8 Engines” and “How to Restore Triumph TR7 & 8”.
