Can help with that
Starting with the championship, the Endurance Brasil was formed in 2014 on the basis of the regional endurance championship of Brazil's southernmost state, Rio Grande do Sul.
Currently, as stated above, 8 car classes compete, evenly split between Prototypes and GTs/Touring Cars.
Specifically about the P1 and P2 classes, they are as follows:
P1: class for Brazilian built prototypes + LMP3 + Ginetta G57 P2. Engines are limited to 7.000 cm³ if naturally aspirated, or 4.200 cm³ if turbo / supercharger. The only limitations are the following:
Weight/Fuel capacity, based on engine displacement ant if it's NA or turbo
Number of tyres allocated per racing weekend
FIA Annex J safety requirements
More exotic engines like those used on LMP1L or LMP2, or other top echelon classes are also forbidden, to avoid cost to skyrocket
Other than that, design is completely free, both aerodynamically and chassis wise. Tyres also are of free choice, with teams currently using either Yokohama or Pirelli rubber. LMP3 cars are free from the intake restrictos used on the ACO series.
P2 has overall the same limitations in engine displacement, with only slightly different specifications for the pairing weight/fuel capacity. This class is sort of a grandfathering class, for older prototypes that cannot keep up with current machinery. For this reason, the car Tarso Marques built will not be permited in the P2 class, and will compete in P1
