If you carefully read the man for boxplot (?boxplot) you can see in the examples that you can put in a ylim as an argument to the boxplot function:
boxplot(3:5, 2:4,4:6, ylim = c(0, 8))
See also ?bxp.

So where is the reproducable example?
How can we know that you're not doing
abline(h = 400, col = "red")?
You are right, a reproducable example should have been there.
I don't know what I mistyped but I got to work and here is an example that works,
abline(h = 4)
abline(h = 2.5, col = "green")
abline(h = 2, col = "red")
abline(h = 5.5, col = "green")
abline(h = 6, col = "red")
I also tested with the lwd parameter of the abline
abline(h = 4)
abline(h = 2.5, col = "red", lwd = 2)
abline(h = 5.5, col = "red", lwd = 2)
Is it possible to scale the size of the boxplot, so that scale on the Y axis is say from 0 to 8 instead of 2 to 6 as it is in the example from above.
