:think: Well, that is the first time I heard about somebody did from bigger engine smaller. Usually for racecars mechanics will do the standard engine bigger.


They did it to make this car able to start in 1600 ccm class (due to 1,4 coefficient). But I have no idea why they chose 120 engine instead 105. Maybe because S120 engine is a little bit "squarer" what is make engine more flexible. But it's just a blind guess.

If origin of engine is from standard car, it isnt a 120 engine, but slightly resized 105. As far as I know this type of car wasnt made with 1100 cc engine, only with 1050 or 1200 and later with 1300 cc ones.
