There are plenty of techniques in the past that make RSA a bad choice altogether.

If you are going with it anyway, yeah, 4k bits is a safe choice for making it reasonably secure right now (2k being a bare minimum), but remember, attacks always get better, never worse, and RSA has a fair share of possible attacks.
