electrics are easy fred, so don`t let anyone give you the scare tactics of "ooooh its an import" that was true a few years ago but its not anymore, you`ll find the bits you need you just need to find the guy thats buying in at the time, engine parts can be got in the uk, and most spurious bits are fine to use, with exeption of the cam belt tensioner, you will have two kits to buy one will have a belt the other the belt with tensioner, get the belt kit in a motor factor and pully from nissan, if they can`t get it for you (import) then go with the tensioner from the kit, generally there not good and can give out under load after a few thousand miles...
and its like brakes on a car, the cam belt is something you need to know is going to work fine...
