Independent Reviews: Reviews for the previous editions: "This volume is divided into 17 chapters dealing with all aspects of the cars.

" – TR Action"Concentrating solely on four-cylinder TRs, this is as comprehensive a tuning manual as you're ever likely to find. " – Octane"I would recommend it to anyone who is interested, not only in modifying their TR, but in understanding just what possibilities exist and where there may be opportunities to make small improvements when they come to replace worn out components.
