FIAT 124 Spider Engine Maintenance and Modification
Click here to download.
This is the most recent version of my popular guide to working on your 124 Spider. It is heavily focused on the combustion cycle, from tuning your car to selecting carburetors, heads, and exhaust systems. It covers fully the various Weber carburetors FIAT used on the vehicles and the Bosch L-Jetronic fuel injection system used on the Spider 2000. It is useful as a primer in getting a Spider optimally tuned using off-the-shelf parts without serious engine modifications.
