Default LS6 Intake

I found a LS6 intake on Craigslist the PN is 12561184, from my research it is off a 01-02 Camaro, can someone verify the it's a direct bolt on on a 04 Vert and what are the things I should be looking for. I am familiar with old school stuff in Al manifolds, but not sure about any inserts or typical warp problems.
Thanks,
tentuna

Ok, thanks for clarifying and keeping me from making a costly mistake in time and money

You will have to buy new coolant lines or shave the ribs off the bottom of the ls6 intake. Other than that its all straight forward

Not sure why you're shopping for an "LS6" manifold. If you have a 2004 year model, you already have it.

Yes, check your intake cast number and make sure you have an LS6 before anything now!

It is. Just add a CAI, heads, cam and headers.

Being serious, that's what GM said it was worth...

Im new to the ls world. Could you give me a brief explanation on this plz?
So 01+ ls cars have ls6 intake manifolds. This is what gave the later vettes 350 vs the 345 hp? So your gm claimed it was only a 5hp gain when it was really more?

Specifically, ALL LS1 and LS6 C5's have the same intake manifold from 2001-2004. Technically, there is not such thing as an "LS6 intake", unless you want to call it that, purely because it was removed from an LS6 engine.

Ooohhhhh, so if it put an 01+ intake on my car itll give me 5hp roughly with a near stock car, i assume this also means no tune required? So when combined with say 243(z06) heads and a z06 cam, ill make better power overall with this manifold?

The 01 LS1 also has a different cam than than earlier LS1s. The LS6 manifold was not the only change made on the 01 LS1s. you are correct the engine should make better overall power with the LS6 intake. If you are thinking about swapping cams. Don't go with the Z06 cam, there are are much better cams available.

Holy crap this is tough lol. There are wayy to many variables with these cars lol. Id basically like to have an ls6 with intake, full exhaust, and tuned in my 98 auto. Its a dd and i dont want to get too crazy with power plus budget is a major concern. Any work would be done at home. Id hate to threadjack any further bc it seems this is starting to go in different direction. Ive got a thread titled bolt on options. Im asking about heads cam there. Mind joining in there??

Tough? No, every part means something, and they all interact with each other. Nothing difficult about it. How much gain you're going to get from one item depends upon how weak it is to begin with. As a rule, there isn't much that's weak about these motors stock. If you want major hp increases, you need to change something significant.

Probably the single best bolt on would be a set of headers, followed by a CAI, something like a Vararam. Getting air in and out is what it's all about. As you keep making the weakest link better, you make something else become the weakest link. I would not place the intake at the top of the list till several other items were new, Jmo. It is easier and less money than headers tho.

Ive got a cai(k&n) and catback. I was planning on headers, saw some used ones in the classifeds. I was just thinking of getting the build list together, getting all the parts, doing it all at once, that way it goes to a tuner 1 time and its done. I dont want to go too crazy, its a dd, and money wont allow anyway. But if some parts arenot worth the gain, i wont use it.

I did headers, offroad X pipe, TSP 228R cam, and tune. Car did poorly on the dyno, felt anemic, I was very disappointed. Snagged an ls6 intake, halltech air bridge and filter, LS2 MAF. Had the tuner copy the stock ls2 MAF table (creatively, the table is bigger, different graduations from LS1, first and second half of the table graduations are spaced different on LS2 table, etc) into my PCM, tweak the maps and picked up about 40hp and the car came alive.

Well, 99 there is a great example of what parts do. Now, his parts didn't do a whole lot UNTIL he got a tune that complimented them. I'm pretty certain if you ask him, he'll admit that his tune alone, without the parts, would not have added 40hp. Obviously, the parts without the tune didn't either.

The whole package working together is where its at. That's why its so hard for anyone to say what the gain will be from xyz, or that item A is worth doing but item B is not. Item B might only work if item C is on the car, but that doesn't make it worthless (if you get what I mean)

That's exactly what I was trying to point out. I changed a bunch of stuff that was supposed to add this and do that. Without the whole shebang it still sucked.

I did get the car tuned with the first round of upgrades. I just didn't run very good. M6 car with 228R will barely idle without a tune. A4, fuhgetaboutit.

I get what your saying. I think for now ill focus on the exhaust. Decide on what heads and cam i want save up and decide if its worth it and how i feel at that point. I have a feeling 243's and z06 cam will be the ticket. Gotta get everything else straight though.
