Cam & intake options for the LS4?

I've seen 1 or 2 people that apparently have a cam, but it seems they went through quite a bit of effort to make it work. So is there any word on more options coming out in the future? Also we have LS6 heads right? How many here have done the LS6 intake swap? Was the 20-30hp worth the pita of swapping everything out?

If you are using the SS for long drives/daily driver, I personally recommend not messing with the cam and intake.

I have heard of others using an LS6 intake with really no notable gains. Stick with exhaust, air intake, and maybe a tune and you will be plenty happy. And if your not, then maybe think about going balls deep.

Theres plenty of juice to extract from that restrained LS4 with simple bolt on mods.

Agreed. Imp has a few mods and his is pretty badass.

Not sure where you got any of that info from.

There are MANY MANY MANY people using cammed cars as DD's and before the whole "trans is weak" comes into play, there are more people that have NOT had a trans failure than have had one(I've had a trans failure).

Next, LS6 intake is good for about 10-15 by itself BUT the reason it is being utilized more than the LS1 intake is cause people want to go with a cam next and the you get a higher RPM range with the LS6. If you don't want to cam the car then save your money and buy a LS1 intake. LS6's go for $300-$350, LS1's go for $50-$100 just for the intake, then you have to buy all the parts to make it work.

IMO there's no reason to buy some larger piped exhaust if you're going to keep the restrictions at the motor, kinda defeats the purpose unless you just want to make noise.


OP, Yes the few guys that are currently cammed did go through a bunch of shit BUT they were also the FIRST guys to attempt it. As with all new engine modding, there's gonna be ups and downs.

YES, we have LS6 heads.

I don't think anyone on HERE has done the LS6 intake swap yet. I have 90% of the parts sitting in my garage and will get it done when I can, but I'm also removing all of the DOD(ie:lifters, valley cover) shit from my car too.

There's pretty much everything we need on the market already:

Headers- Doug Thorly
CAI- K&N, Cold air Inductions
Exhaust- magnaflow has a bolt in kit or you can piece together your own
Cam- I recommend finding someone that can Spec you a cam
Turbo- Cartuning, they have a inter-cooled and non inter-cooled kit
Nitrous- piece together a kit



LS1tech.com has a bunch of info about modding our cars. Just go and "lurk" the site if you don't feel like joining another forum.

Thanks Joey!


My mods are(for the op):

Scorpion 1.8 rods and rockers
K&N CAI
DMH 2.5" e-cutout
Dyno tune

I put down 270hp with those mods. I don't know the tq cause his cord wouldn't reach(damn FWD). I am up 30hp over stock, BUT it was about 100* outside when I had my tune done and the pulls were made compared to it being about 80* when I dyno'd 242hp stock.

Well, I got my info from the source you are referencing... LS1Tech... "LS1 Intake swap with dissapointing results:"

Ls1 intake swap results :( - LS1TECH

Also, You really reccommend that a new owner rip apart his motor and void the warranty he has for maybe a 15 hp gain? He inidicated hes looking to use this for a daily driver/long drives, so I would think the warranty would be more valuable then a few extra horses. Just my recommendation, thats all. No fact stating there, only opinion...

Itd be one thing if he just bought an 06 with no warranty. He paid a little extra to get a car with warranty and this would leave him fairly vulnerable.

For this reason I recommend bolt-on starter mods that can easily get him into a 13 second quarter mile... I disagree that exhaust mods are useless without a CAM and intake. Aside from the fun of the rumble, others have done those three mods (ehxaust, CAI and tune) and gotten well into the 13's. Theyre also EASY MODS that are not that expensive, and do not give you warranty issues (sans the tune). But even I had a tranny replaced while tuned under superchips


Also... did Doug Thorley ever fix that terrible whistle sound on those awesome $600 headers? After all the bitching I heard about those I wouldnt pay $50 to throw them on my LS4... havent been following though, so Im not sure if the issue was ever rectified.

Well the OP was the one that suggested a cam and intake swap so I'm willing to bet he doesn't care about a warranty.

He didn't say anywhere in his 1 post in here that it was a DD/long drive car(I don't read 90% of the threads on this forum so if he said it somewhere else oh well).

You should lurk Tech a little more, thats 1 out of probably 15 or so successful swaps. Not to mention that guy probably had issues with his tune being off.

To be honest he could simple put a tune and get some DR's and get into the 13's. Other than manufacturer claims no one has proven that a CAI or exhaust give you that much of a bump. I felt a small gain when I first put the CAI on my car, but I didn't really feel any gain when I added the cutout.

I think they did fix the whistle but I dont know for sure. I don't read the DT threads anymore.

The headers as of now are my best mod and I would do it again. They are a supporting mod for everything else to come.
