im for the 12a turbo or not, i bought some parts off a guy with a a12 n/a rotor in a bluebird, the thing was 1-2 car lengths a lap slower than his worked l24 in the same car.... ig got eh rotor, it looked better in the engine bay thats for sure
also better weight distribution due to compact nature
i wont do a rotor though because im a tight arse that cant be bothered engeniring a motor to an old car..... i like the old style cars with old dtyle power... carbs cams and a big smile on my face.
