I've never looked into it, but I bet you 1 cc of 98RON petrol that the spray nozzles are the same as 90's era Nissans, e.g. Maxima, X-trail etc.
Why would Nissan use specially made nozzles when they can use the one part across multiple cars.
If you can, I would measure the R33 nozzles, then go to the nearest wreckers and look for/size up similar nozzles.
