"Nie mamy pieniędzy na więcej badań."

Translation: We do not have money for more research.

we do not have the money for further researches

"further" doesn't exactly mean the same thing (it's 'dalsze badania'), although it makes sense here.

'research' is rather uncountable. You could maybe say 'researches', but that's rather old-fashioned, people may correct you.
