then i sanded the whole hood with 180 grit and applied a dust coat of self etching primer
https://sl-i.net/FORUM/images/imported/2008/12/IMG0064A1-1.jpg

That looks pretty sick! Great write-up.

[xXGTBspecXx]

ran into a few problems along the way.. bondoeing in 40 degree weather makes bondo crack when its hardend.. pissed me off i had to re bondo and sand for an additional 3 hours..
if u have the know how and the patience this is a awesome mod. if u dont then its a PITA that pays off in the long run. genuine win win situation.. lol

[Grafton]

first thought: eeek sharpie on my old hood
second thought: AHHHGGG sloppy hole in my old hood
third thought: oowwww looks good finished

[xXGTBspecXx]

lol :smt005 and i plan on adding a small 1'' scoop on the pass side right over where a intake cone would be.

[2.5GT]

Looking good...now let's see it on the car! :grin:

[xXGTBspecXx]

here its on the car but still not finished it looks like ass up close..

well done!

[chipLRX-SLI]

fricken sweet man . i was going to do this to my 1991

[xXGTBspecXx]

update

[impreza_GC8]

Wow that is incredible. I want that exact hood. I need a better scoop for my TMIC and I want a small scoop for my intake. I would love a hood like that, too bad you live so far away, I'd bring you a hood and pay you to show me how to do it.

[xXGTBspecXx]

lol actually if the price was right id trade hoods with some extra cash.. alotta work went into this one and i still gotta finish the crack on the scoop.. but now that i know what im doing id love to do another hood like this.

[Okin DaVanh]

If you have more than 2 coats of clear, wetsand and buff it. If it's just 2 coats, try buffing it out (Tho it won't be very glossy) with a coarse compound and a higher rpm range on the buffer. It should shine up a bit more than what it is now. Hope this helps.


Looking good so far. :smt023

[xXGTBspecXx]

update!

[99gtlimited]

well done man, i'm impressed the bondo came out that well in the cold weather. It can get really frustrating if it doesn't set perfectly or the cold makes it crack.

Keep up the good work and keep posting it for us to see!

[anothernord]

Ahh. I just found this DIY. I'm hoping my body shop guy can do this for me!

[Sarra]

I will be doing this with a carbon fiber RS hood and a 4" bugeye style carbon fiber hood scoop. O_O

Excellent. now put a turbo and intercooler under that scoop!

[legacy22]

im doing this but with fiberglass so it doesnt crack!

[Matty2Hotty]

Bringing the Thread back! I did this but no bondo, just bolted mine to the hood and its not going anywhere! Cant wait for it to fully dry and cure! Its sitting in my bedroom at 80degrees. Crappy cell phone pics right now!

Im a plumber... I used Closet/Toilet bolts that are like 2" long instead of the little 1/2" bolts that come with the scoop. So all i needed to do was drill the holes out where they mounted on the scoop. I screwed up and didnt think of this untill i hacked and cut up my hood alot. I should of took my time and not rushed to be 100% perfect. It looks great though so dont get me wrong! I know you used fiberglass and what not to get a nice smooth surface so it looks like the scoop was built into the hood. Mine is just bolted on so i can always change it out or do something different in the future that is what i ment!

Like so:

[anothernord]

It would be better to have a hole in the hood under the scoop so it is a true air scoop, and not just rice. But it does look cool.

[Matty2Hotty]

no no... Mine is totally cut open like xXGTBspec and free flowing air! I made a metal cover though that is bolted to the hood to direct water to the back of the engine bay so it dont get my engine bay soaked. Summer time i can unbolt it off too! Since am in Seattle... It Rains ALOT so that is why i made up the cover plate!

Ah, I see. Throw up some pics of your setup from underneath!

...man, i got the sti scoop and air splitter just sitting here, im hesitant to start as i know nothing of bondo, rivets, etc.

[Matty2Hotty]

Gotcha wait till tomorrow once she is installed! I was worried about bondo, rivets and crap... That's how I came up up the toilet bolt fix to beable to bolt her down, just drill out the holes for your scoop on your hood and I used a hand grinder with cutting wheel to get the air flow cutout.

My splitter is about to go in the trash or sell it for $10.

[Matty2Hotty]

So i got off work late... It was already dark so i took some garage pics really quick to get a good idea.

Summer Time Cover plate i can Unbolt for straight fresh air. It is C shaped a little to flow air into the engine bay but towards the firewall.

https://sl-i.net/FORUM/images/imported/2010/03/e2f41ed3-1.jpg

that looks good, what'd you make the cover from?

[Matty2Hotty]

Just section in Lowes, they have precut sections of metal for like $8 to $20 in different sizes and thickness of metal. Went i cut out my hood scoop section i left the main brace section on the underside(that is what i used 4 screws to secure the plate too... So if you look closely inside my scoop you can see you the braces still there. Daylight pictures might be better.) BUT... 99 and earlier hoods might have different brace setup on how the hood are molded.

[httrdd]

Great thread. I am sure it is pretty cut and dryy, but the whole layout is great. Nice DIY where ever you are. Lol.

[B's Legacy Wagon]

just a suggestion. i was thinking about how it hard when your not a bondo man to get the bondo just right and the finish to look good and smooth, rather than painting where you may see blemishes or paint inperfections. try and wrap it with vinyl i have seen some of the hood kits that come in mat and gloss finishes, not ot mention the Di-noc carbon fiber wraps. there are videos on you tube showing them do complete cars etc.
I think it would look nice, and hides any inperfections in the body work. I am going to try it myself someday soon with an 07 WRX hawkeye scoop.But iam still debating weather to wrap hood first, then wrap hood scoop and install like Matty did. Or trying to attach the scoop first and then wrap both at the same time. just not sure how to handle the extra material needed to cover the scoop in the middle of a sheet.

[httrdd]

Bondo is really not hard if you take you time and sand it smooth. I have done some bondo work before. That vinyl would be more of a pia then the bondo would be. Never tried it, but have seen vinyl wraps done on NASIOC so same thing.

[Granny]

Just put a STi scoop on without bondo.

^ Now that is more like it!

[xx97LEGACYxx]

lookin good :D

[95scoobie]

Where r u guys getting the scoops from?

[grayguy]

Try Nasioc

[geckoboy86]

Ya...we are just getting them from imprezas...Either local papers, craigslist, NASIOC, eBay, or other methods (like maybe buying new...dont do this)

[Matty2Hotty]

If you lived in WA you could buy my hood for cheap
http://i264.photobucket.com/albums/ii199/WashHottestPlumber/0e0a721e.jpg

[httrdd]

My 07sti scooped hood is for sale as well.

[98legacygt22]

Not to bring back an old thread but did you guys start out with an L hood? I have a 97 LGT that came factory with a hood scoop and I want to cut it out and install an STI hood scoop since I am going turbo.

[Dead91silvia]

If you are going to use an Impreza scoop, you will need an "L" hood.

[98legacygt22]

Ok cool I'll just swap with someone for a black L hood.

[FirstGenLegacy]

I was wondering if anybody has ever built a custom intake to fit under one of these scoops?
Would it work, or no?
*Not talking about an intercooler like the Sti.

[98legacygt22]

You would have to make some kind of water separator, but I have seen what you are talking about. I'm sure there is a pic of it on here somewhere.
