the speed is 40km/h not 52km/h on the 920.3, the interior sounds for the straight pipe turbo dont work on 920.3, may be smth to look into! but else a good mod
I wish people made more unique MTZ models, not only like these boring 820, 920, 1221 ones. I suggest people to do something else for once a while, like 920.3, 900.3, 1221.5, etc.
