You can keep the R200 diff, your weak point isnt the diff but the axles. The snout/spline into the hub have a tendency to twist like a pretzel once you start hitting a certain torque. Not sure of the number honestly but its not the HP that kills it. I've had buddies in Japan who were going thru stock R200 axles in their R32 RB25 with HX40s pushing over 600whp. One upgraded axles to fix the issue, the other swapped out to the larger R230 diffs/rear end off R-32 GTR/Z32 TT rear ends.
