I have one of these on my car and it is in bad shape. I like the look of it and I was wondering who makes it?

 

If I am looking at the picture right, that is the Nissan vent that was used on the 260Z to 280Z to combat the fuel boiling problem the Z had back then. They had it listed in the last racing parts book I got from them. It was an option for the cars then. Don't know if you can still get it from them. Good Luck, Rich.

 

I was talking about the center fiberglass part; not the two side vents.

 

Yes, we are talking about the same thing. It is called the Z competition hood vent introduced: dated 12-13-1974, Part Number # 99990-00182. It came out as a field fix in a technical bulletin from Nissan to cover the underhood heat from the exhaust system of both the 240 and 260Z. It was mostly for the old flat top damper-pot carburetors (boiling of fuel in the carbs). Don't know if you can still get it from the Nissan company anymore. But you can always check and see. Good Luck, Rich.

 

You can also go to and read the following article: WWW.Zhome.com and then go to the Z-Technical Libary, Look under Documents (index of technical articles), go to the General Discussion Area from there go to the second article starting with 1973 Dealer Modifications. Then go to the section called "Meanwhile back at dealership @#%*+%#*!" drop down to additional measures taken #4 and click on competition hood vent to see the write up by Carl Beck. Hope this helps.

 

Thanks that was a lot of help.

I had no idea it was a nissan part or that it was rare.

I am gonna pick up a fiberglass repair kit and patch up the chips. Someone bondoed it to the hood and most of it cracked off. Should I make it flush with the car with fiberglass? If I do will It crack off like the bondo did?

 

You can glue it to the hood with panel adhesive available from MSA. I would take the car to an automotive paint supply stoe and show them what I want to do. They always have someone willing to help in my experience.

 

You can use short strand fiberglass or long strand fiberglass and it should hold without cracking. You can also use the above message #7 and use glue to keep it in place. I have used some of the new 3M glue with a lot of success. Find a store around there that sells Auto Body material (perfered 3M) and tell them you need to attach fiberglass to metal with the glue. They should be able to give you the right kind. It will work pretty good. Good Luck, Rich.

 

so would I lay the glue, then place the fiberglass mat, then apply the hardener?

 

You, first need to plan where you are going to place the part on the car. Make sure you grind or clean the area where you are going to glue the part on. The area has to be roughen up some to get the glue to hold. Then place the glue (follow the directions) on the part and put it on the car where needed. Let the glue harden before adding the fiberglass (may take a day or two). Then grind the paint away from the part for at least 6". Blow off the car next and then get your material together for doing the fiberglass work. Next, you start with a small part of fiberglass (check can for directions), then mix the hardener in with the fiberglass. Then apply the mix to the area (working from the painted area to part)(make sure to put some of it on the part)(if the fiberglass gets to hard before putting it on, get rid of it and get new mix). Then let it dry and then sand the ridges down. If you need to, add more material if needed. After you get it to what you want, sand it down to at least 180 grit. Then spray with etching primer. After that dries, then you can use regular primer (cover the whole fixed area). Wet sand down with 400 grit (do not go all the way thru to metal) (if you do go thru, repaint and sand again)and then you can paint the part. Good Luck, Rich.
