WoolMan's Firefly Homepage

This page is devoted to the Pontiac Firefly (and its
relatives) because I like these cars. My first car was a 1987 Chevy Sprint
with an automatic transaxle and a 3 cylinders 1.0l engine. Since then,
I bought another one, a 1989 Pontiac Firefly with a manual transaxle and
a 3 cylinders 1.0l TBI engine. The weirdest Firefly I ever saw was a 1988
Sprint with a custom 1.9l engine and a manual transaxle. I drove it for
a ride, but it's performances were not as good as they should have been.
I would like in the future to get my hands on a Firefly Turbo. |

Firefly General Info
These cars are technicaly refered to as "M Body" vehicules by GM. All
these vehicules are built by Suzuki Motor Corp. (Swift/Forsa) and imported
by GM (Firefly/Sprint/Metro).
The platform was introduced in 1985. Major changes were performed on
1989 models and 1995 models. In 1989, Suzuki changed the name Forsa for
Swift.
The available engines include:
-
3 cylinders 1.0l 48-55hp (most common)
-
3 cylinders 1.0l turbocharged 70hp (Firefly/Sprint/Forsa Turbo)
-
4 cylinders 1.3l 70hp (standard in Swift before 1998)
-
4 cylinders 1.3l DOHC 16-valves 100hp (Swift GTi)
-
4 cylinders 1.3l SOHC 16-valves 79hp (1998+)
-
4 cylinders 1.6l 92hp (some Swift sedan models)
-
3 cylinders 1.9l (custom)
The 3 cylinder intercooled turbo engine was abandoned in 1992. The 4 cylinder
1.3 SOHC engine has the same power but less torque.
The most interesting models are the Swift GTi and the Firefly / Sprint
Turbo 89-91.
The combination of the standard 3 cylinders engine with an automatic
transaxle is for grandmothers only.

Firefly Mechanic
The Firefly is a great car for do-it yourselfers because its mechanic
is very simple (especially the fuel injection models). Also, there so much
room under the hood that you can do most repairs with the engine still
in the car. Also, all the parts surrounding the engines are easy to access
and very few of them requires to get under the car. However, if the car
is equipped with air conditioning, things may get a little bit more cluttered.
Great books for doing repairs and having full specs. & schematics:
-
Chilton's Repair Manual for Chevrolet Sprint & Geo Metro 1985 - 93,
including Turbo
-
Haynes Automotive Repair Manual for Chevy Sprint & Geo Metro 1985 thru
1994 (no turbocharger info!!!)
