There are four generations of the 3S-GE, which were used in the Toyota Celica, MR2 and Toyota Altezza. All 3S-GE engines had a displacement of 2.0 L. Additionally, the 3S-GTE engines were based off of the 3S-GE designs.
Gen 1
First generation 3S-GE was produced from 1986 to 1989, arriving in both Northern American versions, as well as In Japan as a second variation. The Northern American engine was slightly less powerful, producing around 135bhp or 100kw. This engine was the only Gen 1 3S-GE to come to North America, in the Celica GT-S (ST162). The JDM version, sported a more aggressive ECU, and among other things a lack of the EGR valve system, pushing the output to somewhere around 150bhp or 111kw, and 125ft/lbs of torque.
Gen 2
The second generation was produced from 1990 to 1993. Receiving a slight boost in output to 160bhp or 119kw, and it also proved to be a slightly more reliable engine. The 2nd Gen also did-away with the T-VIS system, which was replaced by the ACIS (Acoustic Controlled Induction System), proving to be much more efficient.
Gen 3
The third generation 3S-GE was produced from 1994 to 1996. Power output was increased to 177bhp or 132kw.

3SGE BEAMS
The fourth generation 3SGE is also known as the 3SGE BEAMS. It began production in 1997, and is still being produced for the Altezza. The 3S-GE BEAMS was the first Toyota engine with dual VVT-i, increasing the available power to 197 bhp.
"If engine could be beautiful, this would be the one!"
A Few facts:
This 3s-ge BEAMS VVT-i "Red Top" version is generation 4 of 3s-ge and was available in few models sold only in Japan - Toyota MR2 G and G-limited, Celica ST202 SS-II and SS-III and Caldina.
This 2.0-liter 3S-GE BEAMS engine with VVT-i ( Variable Valve Timing-intelligent ) produce 200 horsepower and 21.0kg-m of torque.
The production in MR2 wasn´t more than 1000.
Turbo'd Beams VVT-i 3SGE was used in TTE FIA WRC Corolla, but 80% parts of engine was modified.
There was also "Black Top" version with dual VVT-i which produce 210ps/7600 rpm, this engine was in Altezza.
This engine is used in Japan in Formula 3!
