hood scoop

Yepper, get a stock 79 capri scoop and paint it to match. It is a bolt on affair, drill 6 holes and you're good as gold. Cut the hood open as big as you wish. Ends up looking a lot like a TII scoop (40% wider and centered). I backed out of doing mine since I plan on going turbo in the future with a fmic. You'll see pics of a mock-up where I bolted it on a scrap hood, and a pic of it set on my hood and for comaprison a pic of an FB with a TII scoop modded on.

Yikes! that capri scoop is a bit much. If I went turbo or otherwise needed a scoop I'd get one of the fiberglass or carbonfiber hoods from fibremaz here. Im not sure if anyone stateside has put one on yet but the projected price was reasonable and it'd look a whole lot better IMO...

I have shown this here before. I cut the bulge from a damaged 280Z hood and used it on my 84. I just don't like scabbed on fiberglass parts - I think they look cheesy. Everyone seems to like mine when they see it. People who don't know RX7s never seem to notice it. I used closely spaced tack welds to prevent warpage, then blended it with Bondo type filler.
Another option is to use the hood bulge from a Mitsubishi Eclipse/Eagle Talon.

Although technically its a vent,not a scoop,I figured Id pop my contribution in since there arent a lot of hood scoops in the world of first gens.Probably due to the general "function over form" thinking of most 1st gen owners.
Mine is actually functional (very much so) ,and I dont care much for protruding type hood scoops.The inverted vent has no profile and although its big,its not readily visible unless you are standing next to the car,staring down at it.Its made of the stock steel,folded and bonded to match the angle of my Howe radiator.No welding or bondo was used,so its super smooth and rigid.

It is on their site,mainly because I pushed them so hard to make me a GTO wing.They hadent molded one in over 10 years and werent sure if they even had someone who could handle it.The job ended up being subbed out,but it came out well.I also picked up my widebody in person,hauling a little Uhaul enclosed trailer behind the RX-7.....I hit 125mph a couple times on the way down there,with my old S4 TII setup.I ended up touring the shop and chit-chatting with the owners for most of the day and they offered to put up some pics if I sent them in.Theyre older pics, and I think they only put up the exterior shots since thats what they sell.The car is done now,after 10 years Im tired of working on it.Winning best 1st gen a couple years ago at Sevenstock gave me closure on the car and Ive moved onto other projects,although I still drive it nearly every day.
Heres my current setup,has about 6 years and 50K miles on it.Full specs are here....

Why do people hate on the noncentered scoop? It seems like it would be perfectly functional, would sit directly over the carb (12a) and would require no cutting of the hood braces. Am I the only first gen guy who thinks this would look nice and work well?

you know i was thinking the same thing for 12a cars.. what you think of my idea find a big pot for stew that is the same size of the air cleaner case (for those who cant make there own or want to spend little money). drill and cut all the holes need on the bottom. cut the top so it will fit under the hood and get foam to make a good seal. cut hole for scoop in hood and get a air filter like this 
. i figure it would take max 3 hours and cost around 100 bucks. depending on what you make ur self ect.

Thats what I'm saying though minus the soup. I think Mazda trix still sells a setup that includes a post that screws onto the airfilter center screw and a disk that fits over just the air cleaner, so air comes in 360 degrees around the air cleaner. Then just cut a couple holes in the hood, through a scoop on over them, figure out a way to make a seal between the box and the hood, et voila! Functional, easy, and most importantly nothing from a capri. Just kidding.

i was thinking of puttin on a scoop but i would like it to seat directly onto my air filter when i shut the hood. is there any place i can find a new air filter set up so the scoop will seal and create ram air?

i have had a 300z scoop for some time now and can't bring myself to cut my hood... i guess for fear of letting unnessary water into my engine bay area... i don't know how the twins would react to that...

Carburetted guys, be wary of cold air intakes and "ram" air intakes.
Carbs need a certain amount of heat energy to vaporize the fuel and not freeze up.EFI doesnt have this problem because the injectors are forcfully spraying the fuel out and they are postioned deeper into the engine where its hot.The carb is all alone out there in the cold,which is exactly why there are hot coolant passages cast into the intake manifold,to keep the air/fuel mixture warm enough to stay in suspension.
With a cold air inlet,I used to freeze my Yaw carb up solid after only a couple miles on the freeway.....and that was in CA winters that are barely cold at all,WELL above freezing temps.I had to let the carb breathe underhood air whenever the outside temps were below about 50*F.
Ram air intakes open up a whole other can of worms on carbs.Sportbikes had to deal with that in the 90's, before EFI came about.If you dont vent the floatbowls to the same intake pressure as whats present in the "ram" portion,your carb mixtures will go all out of whack when at higher speeds.
