for the lsd, its actually a viscous slip diff. Most people have experience problems unless using the genuine nissan stuff.
Zmanalex will be able to do you a very good price for a the lot I reckon.
Drop him a pm.
If i remember right, gearbox fluid, diff fluid and molyslip gearbox additive was around 90 quidish
Sorry Neilp but most JDM's dont have the same diff as uk cars. Its normally a mechanical one, best bet is ask ZMANALEX he told me I didnt need the expensive diff oil, halfords stuff would do. As for the gearbox oil Alex sends out genuine nissan oil and recommends a tube of molyslip to put in too!
The coolant is the green kind lol thats my input for that.
