Yup. Wiring won't be fun though. If you intend to modify your SR20, then get an S13, it's cheaper, and it's arguably better because the intake tract is different. If you don't want to modify your SR, get an S14 or 15, both engines come with variable valve timing, but you'll lose that feature if you upgrade your cams.
