SR20 and KA24 pulleys

[GODCHSR]

I think I already know the answer but I'm looking for confirmation.

I bought the Waterpump, PS and AC aluminum pulleys but it looks like they won't fit. I checked my receipt and it does say SR20 on it... They won't work on my KA will they?

(I should have paid closer attention, I just totally spaced the fact that these cars run a couple different engines... ugh newb error)
