Probably oldest roots of any turbo engine today.
Original 2.0T was in Opel Calibra and Vectra A in 1991 having 204hp and 260nm. It was called widower as it was put in light chassis with undersized brakes and aerodynamic coefficient of 0.26cw which is absolute record for vehicle at that time. Developed originally by Cosworth and Opel. Probably best 2.0T engine of 1990's. Unfortunately, GM cost saving policies later made impossible for engineers to keep up with competition.
It should be stout engine, but nothing special. Should not have some infant issues like LSPI etc.
You left some of the history for the generation most similar to the engine being talked about out. While it may be similar the original was an iron block engine.

Development began in 1994, by an international team of engineers and technicians from Opel's International Technical Development Center in Rüsselsheim, Germany, GM Powertrain in Pontiac, Michigan, and Saab in Södertälje, Sweden.[2] Much of the development work on this project was carried out by Lotus Engineering, Hethel, United Kingdom
Sure, there were numerous changes. The Ecotec version you are referring to was nowhere near original version (156hp naturally aspirated). I owned 136hp in Vectra B, and was mediocre at best.
