S14 rear calipers actually have a 38mm piston as well.

Z31 300ZX rear brakes could be a decent upgrade.
They share the same pads as the 240SX, but have a 42mm piston.

'84-86 Z31 uses a 290mm solid rotor, which came in both 4-lug and 5-lug.
'87-89 Z31 uses a 282mm vented rotor, in 5-lug.

I got some from the junkyard to tinker with. I hoped they would line right up as the other OEM Nissan brake swaps, but unfortunately it seems spacing would be necessary.
Another issue would also be figuring out a way to hook up the handbrake lever. However, the mechanism is close enough to the 240SX setup, and I think it can be done with a bit of work.
