And you want to leave the support piston like that?
A nice 320cdi hunter

If you exceed 220 horsepower.
The installed 11mm piston is supposedly sufficient for 0.232mm injectors, but it will be tight.
If necessary, I already have a source that offers a 12V power supply for the pump. However, I'm not really keen on using the larger piston because then it becomes difficult to fine-tune the settings on the chip, as the flow rate would have to be reduced significantly.
I just need a suitable turbocharger now; does anyone have any recommendations?
It should have an absolute pressure of around 2.8 to 3.0 bar.
I don't quite understand how the Holset chargers work.
It doesn't necessarily have to be a new tire; I'd rather have an old one rebalanced.
