Nissan publishes RB figures in newton-metres (N·m) and kg·m. Several of the sources here give foot-pounds instead, so each fastener keeps the unit its sources used and the Units switch converts it.
Use the Units switch at the top to choose ft-lbs or newton-metres (N·m). Converted figures use 1 ft-lb = 1.3558 N·m and 1 in-lb = 0.11298 N·m. Imperial figures are rounded to whole numbers, in in-lbs below 10 ft-lbs. Notes keep their published wording with the converted figure added in brackets, and the source tables always show each figure exactly as the source published it.
Head, main and rod figures are cross-checked across several independent transcriptions of Nissan workshop manuals: Australian Skyline forum threads quoting the RB25 manual, an RB26 list that cites the R32 GT-R manual by page, the RB20 Handbook, and Tomei's RB26 head stud instructions. The smaller fasteners mostly rest on that single RB26 list and are marked as single-source. Where sources disagree, both are shown. Always defer to the instructions packed with aftermarket parts, and to the Nissan manual for your exact engine.
