HS30-H

I don't think you will find any detailed illustrations of the Factory aircon units in the RHD Export parts lists. I have a few of the "R Drive" books and folders, and they only seem to mention that certain parts exist without going into full details. As far as I know, the Factory aircon unit was not fitted to very many RHD export market cars. Here's a photo of one of the earliest schematics of the Factory aircon for the S30-series Z cars, published in the first Nissan "Service Shuho" booklet dated November 1969:

What you are describing does not sound like the OEM unit fitted to the Japanese home market cars as an option. The location of the evap unit sounds like an aftermarket device. Here are some pics from the Japanese market Factory parts lists. This is the unit fitted to most of the home market cars when it was chosen as an option:

The first of the 'real deal' Factory ZGs didn't have any ducting. The ducting was only added to aid the air con / automatic trans cars, and was subsequently fitted to all Factory ZG models whether they were so equipped or not. Lack of ducting doesn't mean its not a Factory piece or Factory HS30-H model - it could just be one of the early cars.

Hi Lachlan, They are what we ( in the UK at least ) call "Trade Plates". I'm sure you must have a similar system in Australia. A car dealer or repair shop will put them on a car temporarily so that they can transport it to and from a place of sale, repair or testing. They are only supposed to be used in a very limited way, but some car dealers use them to take their untested / unplated cars to shows or events. Thats why you sometimes see them on cars in photos. Hope that helps to explain it. Cheers, Alan T.

lvmy240z, Here's the thread I was referring to: Zama thread It was probably just an oversight that you did not reply to the people that offered help and advice to you, but all the same its nice and neat to tie up the loose ends if possible..... :classic: Lachlan, The 432R came without any form of filtration for the carbs ( open trumpets) whereas the stock 432 had a very eifficient and elaborate airbox / filter / cold-air intake system. I'm not sure that the different mesh would actually change cooling or 'filtration' all that much - so it might have been a homologation-assisting measure or 'styling' matter. Surely they could only have saved pennies with the different slat and mesh grille designs? Cheers, Alan T.

Hi Lachlan, Guess what - I had my Radar switched on..... Actually, I'm in Kansai airport waiting for a connecting flight. One of those 100 Yen computer jobs. The mouse is knackered. Actually, I don't feel like answering this question for the person who asked it. He seems to have had a 'thank you' by-pass operation ( or maybe its just me that he doesn't bother to even acknowledge after he has received the info he wanted? ). I don't know why all the confusion about Japanese mesh grilles exists. The 432 grille was no different to the grilles fitted to the other Japanese home market models. They changed design slightly down the years, but essentially all models got the same part number. It was the 432R grille that was different according to the Parts Lists. It had a different mesh, that's all. Matsuo san says that his bar / slatted grille was a victim of the bean counters for the home market cars. The export models got it, but even the design that we got was a couple of slats short of what he originally wanted. I wonder how much this actually saved?.......
