Few general ideas for features.

Hi! I wonder what makes every engine sound unique. For e.g. my in-line 4 from Mazda (2.3 16V DOHC 2006) sounds very different from my in-line 4 from Opel (2.0 8V OHC 1995).
But, to the things.
1) I'd love to hear more unique sounds, more then one for specific engine with some pitch adjusted.
2) I'd love to design my own Wankel engine.
3) I would be great to create so many cylinders what I imagine (with some limitations) but I mean a slider to choose number of cylinders.
4) Maybe you would make some events to design such monsters as This 54 liter radial 18 ( https://www.youtube.com/watch?v=BpWKoXbWVjE ) (Because they are awesome).
