As an eg. I called a Nissan dealer here in Perth. They quoted me :
R32 GTR Oil Pump - $705 incl. GST
R32 GTR Water Pump - $427.50 incl. GST
They weren't N1 pumps ... just the rego stuff
I just bought an N1 water pump from Unique Autosports - $405 to Perth
And will probably get my N1 oil pump from there too as I can't find anywhere cheaper. Apparently you can just get a standard oil pump and put a stiffer spring in it but I don't know how to do that so I'll just pay for the N1 pump instead
The mk3 supra is the JZA70 and yes they came out with a 1JZ-GTE
The mk4 is the JZA80 which came with the 2JZ
It's obviously had an engine swap if it's got a 1UZ-FE in it
