Hey guys I was wondering if there was any way to make a stock s13 diff anywhere close to a 3.5 final gear while retaining stock axles and stock driveshaft. Any help is greatly appreciated

You can probably swap the ring & pinion gears off a JDM SR20DET diff, those came 3.69 stock. I don't know if Z33/G35 gears will fit in the S-chassis diff, but those are 3.5 if they do fit.
