How hard would it be for the dev team to consider realistic VTEC that depends on oil pressure to work? On the super basic level this is just a torque graph for the engine, but on the more detailed part of the simulation it could be something that cannot be turned on if there's an oil leak or severe oil damage, it could be adjusted in the tunning options and be used as a part that can be swapped or added to some cars to have better high RPM torque without having to use the race engine mod upgrade. The system could also break due to impact and get stuck closed/open, be more expensive to repair, and change a bit the sound of the exhaust.
Damn. I thought with oil damage and starvation there also came volume and pressure. I suppose those are also not gonna be added although people could modify oil pumps for higher tier engines?
