First major thing to break to since ownership and just trying to make it a little bit more bulletproof, the only thing bugging me doing this is the speedo sender part I would assume I don't need to change it since it should already electric correct?

Hey guys first post here, recently the gearbox in my skyline started to whine and not sound extremely happy drained the oil and there were silver/gold flecks in the oil. Now this is where I'm having problems are N/A R33s equipped with a rb20det gearbox? I already have a parts list: 25det gearbox/front half of tailshaft/gearbox crossmember. Is there anything else I need to do? like the speedo sensor? Thanks for helping a newbie
