The Complete Guide to Modification for Competition of the Fiat X1/9

The information contained in this volume has been prepared by PBS Engineering of Garden Grove, California at the request of Fiat Motors. In it, PBS makes available to the SCCA competitor the sum total of many years of experience in the preparation for racing of Fiat cars. It is our hope that this information will be of value to those who compete with Fiat XI19 automobiles. Clarification on the methods described, if needed, should be obtained directly from PBS Engineering. This book is not intended as a substitute for the shop manuals and guides that Fiat Motors makes available for the servicing of its products. It is written to be used in conjunction with such manuals and guides. Fiat Motors wishes you the best for success in your competitive efforts with the XI 19.

Modifications of the type described herein are not suitable for vehicles licensed for street use. They will also render the vehicle illegal for street use, as Federal law restricts the removal or modification of any part of Federally required emission control systems. Further, many states have enacted laws with various penalties for tampering with, or otherwise modifying, any required emission or noise control system. Though SCCA General Competition Rules have been taken into account in the preparation of these recommendations, it is the responsibility of each individual
owner or driver to ensure that his car conforms to the SCCA rules. Neither Fiat Motors of North America nor its dealers can be held responsible in connection with any protest or disputes resulting from illegal modification of parts. Fiat vehicle and parts warranties are voided if the vehicle or part is used for competition or if they fail as a result of modification. Competition parts or assemblies described herein as offered by PBS Engineering or any other vendor are sold “as is” without any warranty whatsoever. The entire risk as to quality and performance of such parts is with the buyer.
