For the uninitiated, the GT model is different than the standard 914-6 in previous Forza games, and also different than the 916 concept that is available to vote on.
The 914-6/GT has some pretty significant racing pedigree, beating all the 911s at LeMans in 1970,
and everything else in its class.
Some specs and data:
Engine: Honda K20 (its engine can even be a swap, especially for Hondas and Acuras, called something like “2.0 VVT I4 - RACING” or “RACING 2.0 VVT I4”)
Estimated Power: Around 276hp
Car Team: MC Tubarão
Drivers: Paulo Sousa and Mauro Kern
Championships Raced: Campeonato Gaúcho de Super Turismo, Campeonato Gaúcho de Endurance and the Interlagos Thousand Miles
Also, I see a slight “Group 5” look on this car
