The Metamorphosis of the Geo Prizm Engine



The Prizm was introduced by GM in 1989. It was built to lure some customers away from the Toyota Corolla. Buying American made entry-level compact car was still a focus. The Prizm replaced the Chevy Nova, but in reality it was more like Toyota Corolla than the Nova. Toyota entered into a joint agreement with GM to produce the Prizm by New United Motor Manufacturing Inc. (NUMMI) in California, which was owned by both companies.

The 1990 GSi Prizm was introduced with a 130 horsepower (97kW) twin-cam engine, disc brakes and 14 inch wheels. GM enjoyed some American sales, but the Prizm never was introduced into the Canadian market. A sedan Geo Metro model took its place. That model was introduced to the US market in 1995.



In 1993 the Prizm got a face lift, a driver’s side airbag, and a new 1.8 litre 4 cylinder engine, which was optional on the LSi trim model. The driver’s side airbag was introduced in 1994, but the Prizm never introduced the front stabilizing bar in its suspension even though the Corolla had one.



The third generation of the Geo Prizm came on the scene in 1998 and the most notably change was the all aluminum 1.8 litre engine, which was driven by a timing chain. This engine gave the car more power, but the fuel economy didn’t change. In 1999 after several poor reviews about handling, the Prizm finally got the front stabilizing bar and an engine with variable value timing, which gave the car five more horsepower for a total of 125 hp.



The last year for the Prizm was 2001 so a few 2002 models were built. GM puts its money in the Saturn and turned the Prizm into the Pontiac Vibe in 2003.



Geo Prizm Engines Were Powered By The same Engine



The 4A-FE and the optional 4A-GE engines were used in the Prizm from 1990 through 1992. In 1993 through 1997 the 4A-FE was still used, and an optional 4A-7FE replaced the 4A-GE. In 1998 through 2002 the Prizm was equipped with the 1.8 L 1ZZ-FE 14 engine. The 2000 to 2002 models had the variable value timing engine with intelligence technology.



There were numerous variations of workhorse 4A-FE, which include SOHC-2 value and the DOHC 5-valve versions. The power output of these engines varied considerably. The 4A had a 70 hp at 4800 rpms version and the supercharged 4A-GZE produced 170 PS at 6400 rpms.
