Bore stroke ratio

Hi all. I love this game, but why i can’t get a bore/stroke ratio over 1.3333? I own a Lancia Delta 1300 (1990) and i want to recreate its engine, that have a bore of 86.4 and a stroke of 55.5 so a ratio of 1.556. It is pretty annoying :unamused: .


Long story short - a larger ratio will break the game. Sorry yours can’t be recreated. :cry:
