how about a variable turbo, that starts out at max low-end torque and turns into economy, then performance, and then ends with race. so much high end performance with low end economy.

I think he means variable nozzle turbos, he’s just explaining it poorly. I had one on my Shelby CSX, and I think Porsche uses them currently. Would be a neat addition to the game, although I’m not sure how hard they would be to implement.
Then why would I even consider using any other turbo? I get the best of both. Right now the current choices you have to make, make this a game and get you a big variety of engines and cars.
I also think this adds way to little than for example a LPG or Diesel engine would contribute to the game. So I’d rather see the devs invest time in that or superchargers than in this turbo setup.
Because they’re expensive and often less reliable. It wouldn’t be different than any of the other choices in the engine designer.
Also, I think that the exhaust temperature in a petrol engine is often much hotter than in a diesel engine. Therefore it is not common on petrol engines due to much higher material cost.
@WizzyThaMan In fact, variable AR turbocharger and twin scroll turbochargers (or both) are in almost any factory turbocharged cars now. It is essential to the turbo vs n/a, as a “non-variable” turbo is far from being competitive to modern DI n/a engines. The fact that you can vary the AR or use dual gas flow path on the turbine makes turbo more “usable” in everyday life. Before those, only sports cars and supercars used turbo. Now with emission requirements, new engines from BMW, VAG, Ford (Ecoboost) use those technologies to make great usable engines. The big drawbacks are reliability (as the fast spinning of the turbo and high temperature requires costly material and processes).
And this as been adressed in a post I made about 2 weeks ago: viewtopic.php?f=14&t=4970
