LS1 Lid on LT1
 

Anyone have any pictures and/or write ups on putting a lid on an lt1. Or where are some places i can get a ram air box for the lt1 for cheap. I'd prefer not to spend $300+ on an air box.

Thanks

i heard about on lt1 with a lid dyno 327 hp as a bolt on only car. You must have a ram air hood to do it.

Roadtrip120 comes to mind, it looks really clean, I would do it just so the filter was easier, I hate taking the splash gaurd off to get to my K&N cone filter.

o ya, and heres a pic http://putfile.com/pic.php?pic=8/22919531826.jpg&s=x1

Don't worry, ram air hood will be here soon. Anyone know what is involved in putting one of these on an lt1. Thanks

I have some pics of my LS1 lid on my lt1

beautiful car, you don't happen to have a write-up or how to or something. I have seen some other pictures of lt1's using the ls1 radiator shroud. Would that make mounting it any easier.

i have one in my car

its fairly simple, just purchase a ram air box or LS1 air lid, go to homedepot and buy a 4x3 coupler with the clamps, just put the 4 inch one on the throttle body side and the 3 inch one on the MAF *maf end is a little tricky its very snug* then the maf and the lid just slide right on, you can use a clamp to clamp it down but since everything else is so tight that there wont be any air coming out

I'm starting to really want to do this now.

I hear you. I've never liked my CAI with the filter hanging down in front of the tire. There's always a lot of dirt and small stones in that fender well area even though I have taped the small openings where it looks like the grit gets in.

ive been trying to keep an eye out for the radiator piece on ebay but have been out bid at the last moment on the last 3, im also trying to find someone locally who has supercharged their ls1, and i know theres a couple that are turbo charged here, i really want to do this to mine too

I totally agree. All I need is a better parts list for a clean install and I think I'll do it.

can someone explain why you would do this. just buy a ramair for a lt1. just my .02 cents :engarde:

Do you have a link to this or any pictures?

thats what that is.


i agree if your buying the ram air hood, might as well get the air box along with it.


im doing the ls1 lid swap on my camaro. im running a non funtional harwood ram air hood... i had to do some hacking on the ls1 radiator support to get it to fit.

i left my slp intake on also, next time i hit the track i'll do a few runs with each.

Read post 10 and to add to it, I like the overall look. I could care less if I gain anything.

what secures that bottom plastic part?

i heard a cut down bellow from an iroc-z works well for the ls1 lid swap.

how mcuh are these ls1 lids??? i dunno.. i think im going forced induction soon so i would be wasting my time.. :-/

That is not an LS1 intake setup, its a '97 WS6 LT1 setup. To do the LS1 setup, you need the an LS1 radiator support/airbox base and also an LS1 air lid. I am doing my LS1 setup right now and that dang airbox base does not fit nice and flat on the core support like it was supposed to. We had to remove quite a bit of material from the underside of the base to get it to fit better. I need to get a second Fernco 3" to 3" coupler and cut it down so it will fit between the SLP lid and the MAF.

I am going to this setup because my old LT1 WS6 setup would not fit with the LS1 T/A front clip thats going on right now.

Its easy and not that hard to do, you might need a ramair hood so you can clear the lid and it all fits. You dont need the hood for the ramair just to make sure it fits, I think it will work without it on a Camaro, but on a ta the hood looks to sit lower in the front so there is less room im geuss?

What about with a cowl induction hood for the camaros? I am getting a vfn 2 inch, wonder if it'll fit?

That looks HAWT. is your hood aftermarket or modified?

I just finished doin this on my friends 93 ta with a ram air hood and the air box base off of my friends ws6 wouldnt work on it due to its higher lift in the front but the lower base off of my ss worked fine on it looks good

Ultra Z hood is what I have. You have to modify the lower air box for it to fit. I grinded all the ribs down and tapped 4 new holes on the cross mount bar where the fan shroud would sit. Snug as a bug.

Hey SRZ,
Where did you get the piece that covers the radiator, I know it is an ls1 style. IMO it looks much better than when people cut the lt1 style shroud to make the lid fit. Overall how much did the conversion cost you and where did you get all the parts from.

Thanks

Bought it used off of here for 150 bucks lower air box and lid (that's the lower part you are referring to). He had it pwd coated too. You can use any LS1 lid and just modify it to fit. Took me all of 2hrs to get it just right. Not hard at all w/ a dremel. I'd look on here in the FS section people are chucking their lids setups left and right.

Lower air box, lid, filter, smoothe bellow and relocate the IAT to the other side you'll see it on the box. Make sure to get a 99 lid or newer or you'll have to plug up another hole on the box if you don't. I also did the FRA cutting the box, the FTRA and super scoop underneathe for more air. But I also got all that used too. :D That's it.

I have a 95 z28 with no form of ram air. Is it still possible to convert to a lid with the right parts? Also, what is the advantage of the convertion?

I have done this mod to two other lt1's, (one trans am with vfn 4" hood and , one trans am STOCK hood!)

I have seen a car gain on the streets with this mod over a lt1 CAI so i know it helps out, although no dyno numbers to back it up.

The reason i did this is because if it can help a ls1 then it can help a lt1. I have a camaro so i didn't use the lt1 ram air that come on the ws6's.

Whats up Neal? How is is the lt project coming?

ITS SUPER EASY I JUST TOOK A SHROUD FROM A STOCK T/A OR MARO AND BOUT THE SLP LID AND USED THE LS1 SMOOTH BELLOW FOR THE NECK AND I EVEN CUT THE SHROUD AND PUT THAT DEFLECTOR THAT THROWS UP ALL THE AIR TO THE LID

I have been thinking about doing this mod also, it definetly looks much cleaner than the LT1 Ram air box that I am running now. I have been trying to find out if the LS1 WS6 radiator shroud would work so that I could still actually keep my ram air hood functional? I don't have a factory WS6 hood I have an After market Suncoast hood if that makes any difference.

I know that I could use the FTRA but I would rather do the WS6 Radiator shroud if at all possible.

Question for my 97 Trans-Am WS6
 

I have a stock 97 trans am WS6 LT1
IF I was able to switch out to the LS1 lid from a 98+ WS6 w/ ram air
would my 97's ram air hood be functional with a 98+'s ram air box assembly?

Just let me know what steps I need to take :) Thanks.

what did you make the radiator support out of?

What is an alley speed conversion. Is it a kit and if so, where can i get it. Nice car by the way. :)

who makes a conversion kit? I hear alley speed or whatever does but I cant find a website.

???
 

Is this mod really worth it if you already have a WS6?

For the look, yes.

I never got an answer... if you put the 99+ style ram air intake box and lid into a 97 WS6 with ram air will the 97 ram air hood work with it?

mabey

Maybe doesnt give me the go to order the parts :jest:
Sombody out there has got to of tried thisw and knows the answers!!!

Nice ride

I notice that guy did it.. but I have a much... shorter hood clearance.. and I really want to know if it'l work :)

well i just bought the lower airbox off a ram air LS1 formula so im gonna have to get a lid now and get the hood i know which one i want just have to get it now..... thinking a clear lid would look pretty sweet just have to get everything else together

got mine al done...what kind HP do u guys think it will make

I envy you :judge:

I would think it makes power, do you know of another bolt-on car with 327hp and 350 tw at the wheels?? Af far as i know its the highest bolt-on car with lt1 heads. Some guy with a 96 SS with the lt4's put down 330hp.

Alley Speed is the name of my little backyard hop up garage. I was one of the first to put it on a camaro , it took alot more modifications on a camaro than a trans am with a 4" hood. So i named the mod Alley Speed conversion becasue of that.

I still have the same question unanswered :eek2: Doesnt anyone have the answer? :confused: :eek2: please :hail:

I am going to try it out...I am bidding on a whole setup from ebay. I was wondering what the different choices were for the coupling from the throttle body to the maf.
Does anyone have any really good pictures of it?

I just got this on ebay.
http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEBI%3AIT
So I will document it when I do it.

wanna do it for me? I will be in Amarillo sometime soon...getting tired of Lubbock.

IS there anyone who can measure the box assembly from a 98-02 WS6 for me to see on my car if the ram air holes on the hood will line up to the ram air port on the box?

I wanna see a c4 intake conversion :mad:

Thats somthing to think about.. but I bet thats REALLY incompatible lol since under the hood of a vetter and trans am are so very dif :(

Looking at the pic below it seems easier. It seems more compact

What about this.. maybe I should say screw it and get somthing like this? WIlli t be better than my 97 WS6 set up?... i am getting hastily confused about all this crap :eek2: :eek2: :eek2: :judge:

dont think the c4 would work, i think it would put the airbox right where the hood is suppose to latch.

That looks intresting. I wonder would it fit under a stock hood?

how the hell does air get to that thing? and wouldn't the hotass raidiator behind it heat it up?

Ive used one in a LS1 before.. definantly a load of preformance noticeable.

haha oh, I meant the LS1 airbox setup... how in the world do those things work?

In a LS1 there is an air damn that goes behind the radiator that scoops air off from the ground.

I am sure that setup probably works well but IMO it looks just horrible. My choice with a conversion would probably be a good lid and either the SSRA or the FTRA setup. With a WS6 hood your mods to use that setup should be minimal.

sorry to bring up an old thread...some1 menchioned it quickly, will a ls1 radiator holdown and a aftermarket lid setup work with stock hood? if so gimme info!

nope.

is there anyway to get a lid under a stock hood?

not without hacking up your radiator support or your hood.

Fuck a lid.
They are overrated.

Get a nice Moroso, K&N FIPK , or SLP cai intake.

lol i have one...the lid itself might be...thing is no1 listening im going to go from my k and n to a lid with ram air setup...
on ls1 they say that just the ram air added to their lid setup gains 1-3 tenths and 1-3 mph...
one guy added 150 pound cage, and this ram air picked up 1 tenth and 1 mph...

so, i'm just curious...has anyone documented any before and after gains from switching from an lt1 cold air intake to an ls1 lid setup?

doubt much of a gain for the ls1 lid setup itself...

dont listen to that crap ... it is bs. good idea, waste of time, and money.

I just put it cause no one here has it, cosmetic purposes

so what did u do exactly,, u just bought the radiator guard and the ls1 led and fitted them??

yeah I had to grind under the radiator support a bit

I have a 97 Z28 A4. I bought the LS1 radiator shroud off Ebay for $35 bucks and an LS1 Airlid new off Ebay for $80. I still have my stock hood and what not. Ive been told I need a new hood and ive seen where others didnt get a new hood. Am I going to need a new hood to put this on my LT1??

Not on LT1... on a cam'ed LS1, going from stock lid to aftermarket whisper lid, it gained 10hp / 10tq.
