Custom hood vent

[TokyoNights]

Ive had this hood vent sitting around since last year and I want to finally put this thing on. Here is what it looks like

anyone else have one like this? I know Dousan has one mabie he can chime in.
What I need to know is do you cut the hole in the hood and lay the vent over it then bondo the edges smooth or do you install the vent from the underside of the hood then mold it in?

[Dousan_PG]

i paid a body shop 150 bucks and got it installed professionally. why waste my time and fuck it up? hahahah

[Slidin240Wayz]

cut, align, silicone, bondo, paint

[Maeda]

You wish it was that easy.

After you cut the hood everythings going to flop around and make it impossible to bondo.

[Dousan_PG]

yeah u gotta reinforce and stuff
even mine is sloppy
my friend in japan at his body shop they put this on their track cars, but they do it so the hood is solid..its tad heaveier then stock but it wont be flimsy (mine is kidna flimsy, which i dont like)

whatever. i migth get another different hood anyways, i want DMAX.

[Maeda]

Rivet it on. Otherwise pay somebody a ton of money to do it right.
Dirty D's isn't that bad, but it ain't great either.

I want DMAX too. o_o

[TokyoNights]

riveted might look dumb
I dunno
its just body work, its not like Im trying to balance a crankshaft in my kitchen
blah Ill propably just pay someone to do it
hopefully they will reinforce and crap so the bondo doesnt crack like a week later

[RiceEata]

I installed mine on the inside, rivited it and fiberglassed it before i added bondo.

Mines is mounted higher than where you have it in your picture but i cut off the top section and one vent. I cut the hood so that i could fold the center section down then welded it so that hood was more solid. It wasn't that easy, might be better to let a body shop do it.

[RiceEata]

Oh and also fiberglassed in between the vent and hood right before it rivited it.

[Dousan_PG]

coool nice rice eata

the only reason mine is slightly lower is because vent one, uncut is above the front of fan shroad
vent 2-4 are past fan shroud area and right at the nose of the S14 sr motor. so if water gose in it will drop on nose of the motor and down onto shroad/between shroud/motor

the only disadvantage is if its too high up u urn the risk of water dropping on the coilipacks/plug wires

this is assuming you are parking in the rain

driving its not even an issue (duh)

[Edd240]

rice eata

actually looks good...when i first saw the vent undone i thought it would look pretty nasty but it actually looks pretty sick

[red240]

Looks hot, You could also slot the sheet metal on the hood instead of cutting it all out
That way heat can escape but you still have some strength
I have an m-sports fiberglass hhod but I like this, where did you get the scoop?
Thanx

[TokyoNights]

I got the vent from JSpec

Thanks for the info RiceEata
you did a good job on that
I want mine installed lower to pull air from my radiator and the way I have my intercooler mounted

[Ricks15]

its simple to mount it, just center it and with a marker trace the sharpes that form the vent, cut those rectangeles that form the vent openings, and then punch out holes with a small drill bit after rivit the vent to the hood, after bondo the corners untill they look nice, primer and paint. Trust me its easy I used to be in autobody shop class in high school so if you get stuck with something let me know.

[REDSH!FT]

Uhh...what about when you start moving the hood and it flexes? The bondo will crack right of if you're going to use that much of it...

[Kain_Pabyeda]

cut, align, silicone, bondo, paint
No Silicone if you intend to paint...

Can't really see but this is what the inside looks like...

[sittinsideways]

wow man that looks nice. looks like you did some custom support for the hood tho. reall nice. i really like how this vent looks on 240s......so someday mine might be rockin it.....someday

[atom]

Nice work RiceEata, but have you thought about slotting the underside? I kinda like the Uras vent cause it's freakin huge but the vent on your car really isn't any bigger that a single vent since it's all covered up by the reinforcement. I guess if you slot it though rain will become a big issue..........

Nice job tho all around.

[Maeda]

Trust me its easy I used to be in autobody shop class in high school so if you get stuck with something let me know.

I had to do quantum mechanics and physics in highschool. I should ask nasa if they have any problems.

Seriously I seen this in real fucking life, on Dousans hood (who always does things right the 1st time around) and it works but not like people would think.

Simple to put on there, but a week later it'll be misaligned and haggered.

Riceeata has got it down though. He's a mystery to science. He's even from my island home to boot.
Nice hood btw. Please tell me something new I don't know about working with bondo.

[DoriftoSlut]

Please tell me something new I don't know about working with bondo.
Well, John. you need to let it DRY before attempting to sand it. And.... Well, lets start with that one...

[Maeda]

Shit really?

No wonder it's so hard to sand!!!!

no rain isnt a issue

did you read my above post? did you read it? tell me you read it. please tell me. why boy i will ..get over here..get...get dammit over here i wont hurt you --just smack you in the ear..now ....boy!...boy!


pre-paint..duh

btw is the knock off vent just one big vent?
because mines genuine uras...and u see how it is here....whats the word?

[TokyoNights]

it look just like that....exact
but came with cool HIN chicken wire mesh(which went in the trash)

LOL but from your pics you put it lower on the hood than RiceEata. His is higher up and it looks like it's right on top of the engine. If he still got the KA it's right about where the dizzy is.

[Dousan_PG]

yeah but if u look at the bottom of his (open hood underneath) you can plainly see he only made it be one vent
the rest are fo looks.

[ThatGuy]

Why not just spray down the dizzy with silicon? The local Mud-Bog Truckers do it all the time. If it'll protect their trucks when they are nearly submerged, I see no reason why it couldn't protect from a little rain water through these vents.

[kognition]

Lots of opinions here, so i will add my own.
Assuming that is a stock metal hood?
Grind the contact area to the metal. Use a fine fiberglass like a harness weave
so you will have a high fiber content (you will thank me for this) instead of a plain over/under weave. Cut your strips of fabric for the contact area, drill your spots for the pop rivets maybe 4 inches apart all the way around. Lay up the glass, lay down the part and apply the rivets. After cure, you can remove the rivets if you don't want the extra bondo work over them. Now you can go over to the back and cut your desired vent area, and reinforce the cut edges with glass to stiffen it. This is what i would probably do

Nice hood RiceEata and Dousan. Props to you both.

[Ritz S14]

This is actually not true. You can start "sanding" bondo with a cheese grater, as soon as you let it flash for about 5 min or so. Makes a hell of a lot less mess.

[Irukandji]

^yea I only waited a few minutes until I started sanding down my bondo.. makes it much faster and you get the same results...

[slideways2004]

where can you get a vent like that for cheap? i found some on some of the body kit web-site but it was pretty expensive.

[ThatGuy]

As was already stated in this thread. JSpec.

Shit. I'll for taking a cheese grater to my car! Let the bondo work begin!

[Ritz S14]

A cheese grater is as effective as 40 grit paper. It's used to tear down bondo, so that you can start using 120 with less mess.

Man, i just took another look at that vent, i guess you will have to cut the hole out first. My bad.

that's pretty expensive

[Dousan_PG]

180 is expensive? get job. or a new hobby.
i hate to see when you have to buy aero or coilovers.

[kognition]

I would make that damn thing outta CF and sell it all day for $180! LOL!

[ootranceformeroo]

while were on the topic...
is it safe/easy to mold the vent in a CF hood? I think it will be too weak but not sure. I was thinking just get another oem hood and just put the vent in there.

had this thing forever and still waiting to get my money from the fucker that keyed my car. then i can install it =)

no kidding,

aero + paint + install

[slideways2004]

i already have coilovers- jic flt-a2. and aero isn't that expensive if you search around and look for deals. and have backups when something breaks. i have a job and this hobby will hopefully never change. i say it is expensive b/c it's a little square peice of fiberglass. i buy front bumpers for that much $$$$. it is cheaper than fiberglass vented hoods

[TokyoNights]

I decided to do this myself
heres where Im at
http://www.d-faction.com/pictures/mike/IMGP0173.JPG
what do I do to mount the vent before I smooth it out with fiberglass body filler?
I cant rivet it all around because they will stick out to far
so do I counter sink the rivets? I dont think the sheet metal is thick enough for that.
HELP!?

[blackflag_Rms13]

Scotch tape?

Are rivets really to much of a problem even if they stick out? Or you probably just want it to look nice and clean huh?

[red240]

3M makes an adhesive for bonding fiberglass as used on corvettes do a search on google
Do not bondo over rivets, when the hood heats up from the sun the rivets will show up as litte circles an the finish no matter how much fiberglass or bondo you put over them
The thermal expansion is diffreant on the rivet, hood and scoop so it will show up sooner or later , I've had 1 hood and a set of over fenders do this[ I didn't know until it was to late that the shop did it this way] now I have to pull them off and redo it
Jus use sheet metal screws to hold it in place while the adhesive dries then remove them and do your body work
Hope this helps
J

[derek_s13]

my thoughts:

cut some sheetmetal into strips, and screw them to the underside of the vent to make a frame (much like a picture frame). leave an inch or so of overlap off the sides of the vent. place the vent up into the hood from underneath. weld it like you welded the rest of your car. bondo. paint. sexy hood.
