Toyota Engines

[madein1978]

Does anyone know why the Toyota 3S-GE and the 3S-FE engines produce differing levels of power? The SFE is 130 BHP and the SGE is 155 BHP, both engines mechanically are the same, so what makes the SGE more powerful? The car in question is a Carina E 2.0 with the SFE engine.

The engine management system can also be programmed to give different power characteristics from the same engine.
