turbo hood on non turbo?
 

would it fit? someone told me it wouldnt, but i dont understand why i wouldnt.. same body isnt it?

and also its my first car, so im new to that car thing, and its also the first rx7 that me and my friends have toyed around with, so im knew to everything. trying to learn =\

Yes, it will fit.
Yes, it will look stupid.

Yes it will fit
No it wont look stupid.

The lizard/vice grip looks stupid ; )

But seriously. Put your money where it is needed most. Like a FULL tune up or maybe towards some suspension mods.

yes. it will fit...

but whats the point?

yes it will fit and look nice. Like it on my N/A setup ^_^

:rolleyes:


Because it looks better would be my guess.

yes... it would look better... i just dont see the point of putting something on your car that wont really do anything but make the car look like a TII.

but... it is his car... not mine.

pointless thread is pointless.

if he's replacing a steel NA hood with an aluminum TII hood it makes sense :p:

It would be better to get a hood with vents to help cool the engine bay and not direct all engine airflow underneath the car. Having a hood scoop on an NA is counter intuitive as it serves no purpose and will reduce the aerodynamics of the car, not to mention make the engine compartment hotter.

The aerodynamics and cooling difference would be insignificant for a street car. The only problem on a street car is that water, leaves, and other debris tends to come through the scoop and corrode the under-hood components. Unfortunately, the commercially-produced scoop blocks on the market are hugely overpriced.

I've heard pool noodles work well :)

I have a turbo hood on my NA. why?? because it was just sitting in my garage. It DOES look better, and it's a whole lot lighter than the NA steely.

If nothing is allowing outside air into the engine bay to help with cooling and making your car lighther then I guess your right. :icon_tdow
For me its simply because it looks way nicer then my factory hood. And the fact that it ways half as much is just icing on the cake.

Yes.

Although...
Wonder why most turbo II guys leave that hood on once they go to a fmic? Surely its more functional to throw an aluminum n/a hood on it? Oh because the TII hood looks nice lol;)



No. You're wrong...





But I put a TII hood on my vert. Yeah I'll be running a tmic next year, but I put the hood on mainly because imo it looks better/meaner. Everyone has different preferences, who cares lol? Do what you want. Your not going to overheat your motor to death by having a hood scoop...

LOL common sense and car ownership don't go hand in hand.

I love the futility of taking a functional hood off it's given application. Using it as a "show before go piece" and then modifying it to restrict the reason it was made in the first place because of negative side effects from the scoop being used outside it's design intent.

Maybe the person who told him it wouldn't fit was trying to save him from starting down the ricer path? Hopefully the new owner will put that money towards making the car either more reliable or faster.

You are aware that mazda made aluminum n/a hoods, right?:rolleyes:


And... some steel turbo hoods. Thus, making your statement generally wrong.

worry about the cars running condition first then go on to putting tints scoops neon a bangin sub a drift charm jdm stickers aftermarket stickers cromed kobe's a lift kit a glass paintjob hid lights led lights interior lights
omg i forgot monitors in the headlights

I know my stock 91 vert has a AL hood.

A TII hood will not help with cooling; a vented hood will help significantly if the car has a V-mount, allowing the air to completely leave the car.

as everyone said.. yes it will fit but thats POSER!!

Aluminum N/A Convertible hood, best of both worlds : )

im not going for a poser look, my hoods all dicked up and is all dented around the corners, just thinking if it would make more sense to get the other hood rather then the same lol

saying poser is poser
hell do what you want its your car
i would go with aluminum though my hood has fallen on me twice i have the scar to show it

thanks for the advice everyone.. ill prob just be sticking to the same hood but new

hmmm.. i've got 3 alum. hoods, 2/no dents, anyone shipped one before?

and yes i was shocked when i lifted my friends STEEL TII hood, i was like, is this OEM?

So much significance to this phrase if you really think about it;)




O.o mr.10 posts says poser, must be!

Ignorant idiot.





Do what you think looks nice. Its an oem part, not a triple-stacked aluminum demon spoiler.:rolleyes:
Its just annoying hearing people moan and complain about dumb shit lol.


*forgive my mood, I've dealt with idiots for 14 hours straight... then I come on 7club:lol:

[QUOTE=nate91242;10147748]Yes.

Please explain. I removed the rubber piece on the inside and air has to be rushing in when the car is moving. How would a steel hood thats sealed keeping all the hot air in be better? And concerning the aluminum na hood. Yeah its nice but the t2 hood looks so much better.

The air coming in the scoop counter acts air coming through the radiator by essentially pushing against the air flowing through the radiator. Its the same principle with mad-tyte hood risers.

A reverse vented hood would work like your thinking, because as the air flows over the vents, it vacuums the air out of the engine compartment, and pulls on the air coming through the radiator.

Has this been tested by a reputable source to actually make enough of a negative pull off the radiator to hinder it from doing its job? I get what your saying but come on is it that noticeable on keeping the motor from cooling properly?

On a sub 200hp engine, no....this whole thread is silly. But one of our forum members put an Odula lip on his S5 bumper. He ran it once with the bottom bar on the bumper grill. Then cut it off because the Odula has a bar lower. He claims he had 10 degree difference in water temps after removing that bar.

Also the underbelly pan is designed to help with airflow. And I recently saw a RX hood for sale, IIRC it had inlet vents on the front of the hood and exit vents at the back that ran the width of the hood in front of the wipers.

I'm no expert on aerodynamics, but seems logical that all these little things would add up to help the whole system operate better.

As for the aluminum and steel hood thing. I believe the steel hoods were manufactured as insurance claim replacements after accidents in order to keep repair costs down.

i just did the turbo II hood swap last week and im pretty damn satisfies :nod:

just need my new lip, new hood scoop and its ready for paint :icon_tup:

poser or not.. looks damn good to me :lol:

No.
Steel hoods were factory stock on base models.

With my TII hood on my N/A 7, it has the "JDM Hood Prop" meaning there's spacers right where the hinges are letting "hot air" out with the given space it has. When driving you can feel the hot air hitting the windshield and at idle you can feel the fan blowing the "hot air" out as well.

Maybe this can be a method to let "hot air" out better? I read in a magazine that this trick can cool the engine bay 10-20 degrees less than normal (test was done on a 93 miata) no way of knowing unless you test it.

found it!

Aluminum hoods were supposedly standard on the heaviest models (convertibles and TIIs) and also the GTUs, but apparently also appeared occasionally on even the 4-lug cars, especially in '86. Aside from the GTUs, Mazda never made a very big deal about the aluminum hoods in its marketing. When the FC was released, Mazda was trying to do whatever it could to keep fuel economy reasonable, so that may be the real reason why the aluminum hoods existed in the first place and were mainly used on the heaviest cars.

There were some TIIs that came from the factory with steel hoods, not just as "insurance replacements." In fact, I saw one at a car show just a few weeks ago. I have no idea why Mazda did this. My guess is that there may have been times when they couldn't get sheet aluminum for stamping into hoods so they switched to steel to keep the lines rolling, but who really knows?

steel TII hoods are not OEM, you used to be able to purchase aftermarket crash and rust steel hoods, the TII car was sold and advertised as having a aluminum hood.

So you should not put TII skirts on the car either, because only turbo cars had the skirts?



do as you please with the car

There weren't supposed to be OEM steel TII hoods, but they are out there though. The one I just saw was owned by an older guy who bought it new. I remember a thread on this site a few years ago when some other original TII owners confirmed that their cars came from the factory with steel hoods. Definitely rare (and undesirable), but not unheard of.

Seen one here too, on l)arkspeed7's car. i know what an aftermarket hood looks like, almost no one goes through the time of replacing all the factory stickers on the underside of the hood, espially when they are cutting cost by using a steel hood in there first place, like there really gonna go pay for new underhood decals, i think not.
87 is the only year model i've seen with steel TII hoods, but not ALL of them, just some.

We need Geraldo on this...I suspect an aluminum hoarding conspiracy...

The most common sense post, this whole thread is kinda silly and knit picking.

The car I saw a few weeks ago was a Sunrise Red '87. It also had all the underhood decals in place, fully painted underside of hood, etc. And I confirmed the weight of that massive steel hood myself...

I found the old thread I was thinking about:

https://www.rx7club.com/showthread.p...tii+steel+hood

In it, Aaron Cake posted this summary of the steel vs. aluminum hood question:

-most early NAs ('86) had Al hoods
-later NAs recieved steel or Al hoods on random
-all verts came with AL hoods
-all GTUs's came with AL hoods
-sports had AL hoods
-early TII's had steel hoods
-later TIIs had a mix of the two

Same here my stock hood is heavy as shit (steel) and has all the stickers in place. 89 GXL

I think GXLs built after 1986 almost always had steel hoods.

Early automatics came with aluminum hoods as well.

if you are saying a 1987 TII might have had a steel hood I might accept it, but no way a s5 came with a steel TII hood

hoods get damaged before people own the car, at the time a steel TII hood was dealer cost $100, versus well over $100 for a alum.
So you think if something happens to that hood when the car was new the dealer would not replace $20 worth of decals to give the hood a original appearance?

Mine was in a very minor accident, and the good got bent. The jackass previous owner swapped the aluminum hoof for a steel one.

Yes, it's fucking heavy.

i would say if you like the turbo II hood, then why not? Us N/A owners can only do so much to make more power with out giving up body parts and first born children, seems 200hp is the limit if your budget can fit it, bolt on power adders are almost a joke, so why not make the car look good? besids you can only dirve sooo fast...so building your street car for max speed on a track is a wast of time for those of us who just like owning a unique car.
my 2 cents is do what ever you want to YOUR rx7, second gen's are getting to be pretty rare so seeing some one take pride in a 20 year old car is amazing, keep fiddleing with it, its your first car, so no matter what happends you will love it to death, and drive it untell the wheels fall off:P
how ever i do agree on spending money on making sure it runs right, these car's have a nasty habbit of being a finacial black hole! good luck and keep posting so we can see how it turns out!

I meant to type cost was over $1000 for a alum hood, not $100- doh

A whole lot of sense
:)
40 something pound co.pared to 15 or so pound is a no brainer

might as well do s5 tail lights on s4 as well. lol
