IN the workshop manual there is a description of the installation of a 270kw turbo motor. It is believed that this motor is still in its packing crate.
To have made a 360 Turbo eligible for Group A back in the day, they would have needed to sell 5,000 cars with the turbo engine. IMO, that wasn't going to happen, since the 242 and 244 Turbos had strong sales volumes in the USA, and that gave FISA the required homologation numbers. The 360 was never sold by dealers in the US, so it was never produced in the same numbers.
As we know, Mike Minear ran the 360 which he used to set the speed records as a Group A car in 1985, but it was never class competitive. VMS never developed any Group A program for the 360, AFAIK.
Yoda would say "Drum brakes does not a modern race car have." Even in a race car that was modern in 1985. And the beancounters would've blown gaskets at the costs of re-jigging production so the transaxle could take discs. Rallycross rules and requirements were different to Group A.
I'm guessing the 270kW engine being alluded to, was either the late great Gunnar Andersson special, meant for rallysport, or the R-Sport DOHC thing (pic below), mounted on a B23 block. This head was nothing like the B204 / B234 / AQ171 "631" head which appeared on the Sevens much later.
