Modification that come together with the car - Engine

The biggest modification on the car is the engine itself. Some history about the engine.

Group A rallying is the sport from which the Mazda GTX was spawned. Mazda took
the plunge into full Group A competition in 1986 with their B6 1.6 litre
turbocharged 4WD 323. This vehicle enjoyed considerable success over its fairly
short competition life, which led to the continuation of the small turbo 4WD
theme. It was in 1989 that the all-new BG8Z Familia was introduced. The new car
received a larger BP engine (1.8 litre) and made its rally debut in the 1990
Thousand Lakes rally. It then continued competing quite successfully, giving
Mazda another motorsport car to complement the road-racer RX7.The ultimate
version of the Familia is the awesome (but quite rare) GT-R. This hard-edged car
was brought into action in the latter part of 1992.
