Replicating Group A Rally engine with 34 mm restrictor

Hi all. I’ve been trying (unsuccessfully) to create a Group A rally car of the late Group A era (90s), like this Lancer Evo III here: Mitsubishi Lancer Evo III group A (1995) - Racing Cars
Please note the 34 mm turbo intake restrictor. I have tried to replicate that engine, but 2 bar of pressure with that restrictor seems not possible in Automation whatsoever.
Are there any wizards among you that could try and actually achieve that?

What do you treat as the restrictor in the game? IMO heavily strangled intake should work.

The turbine inducer size - I’m assuming the intake restrictor and the inducer size diameter should be pretty much the same thing?

Totally and absolutely not. Turbine inducer size is… basically size of one side of the turbo. Restrictor is a plate in the intake with a hole in it of the specified size.

all righty - thanks for the info. I searched a bit and I think now I understand the difference. I was able to build something remotely similar to the engine in the link with around size 19 Race intake (0.135 kg/s flow). You can easily go with lower though (like size 6 and even size 0 are still viable)
