hey i am looking into getting cams for my 04 cav and i dont really know which ones to get and what do i all need? what would you reccomend?
Any cams are going to need aftermarket valve springs and tuning, at minimum. Though I'd recommend if you're going to spend the cash on cams, you might as well get the head port n polished, and have good supporting mods to see some actual gains - at least a good exhaust system, and upgrading to the le5 intake mani and a bigger throttle body would be good.
Comp Cams carry a good selection for us, though what you pick is really based on your needs and goals. If you're just trying to get a little gain in a n/a daily driver, stage 1s should do you good. If you're going boosted, then you'd be looking at a higher stage. Colt Cams and Delta Cams are also reputable suppliers to check.
Again, you're gonna need aftermarket valve springs, I'd recommend Supertech 78lb, best bang for the buck and they'll handle most aftermarket cams (unless you're getting into cams with a severe aggressive profile).
I guess the first and most important question to ask - what are your power goals/ goals for the car?
i have a magna flow exgaust, pasesetter header. i am going to supercharge it when i am done with getting it painted.

stage 1 if you dont want to upgrade valve springs/seats/retainers.
Stage 2 if you dont mind upgrading the springs/seats/retainers (Ferrea brand is recommended)
We sell a set each week, very popular.

Dont forget whatever cams you get your wasting your time/money if you dont tune the car. If the cams are too much bigger than stock they will also lean out the car with a stock tune.

I'd have to disagree about the stage 1s...I would get a new spring kit regardless. Our stock valve springs HATE any additional lift over stock spec. If you are supercharging it, stage 2's or Comp's Blower Grind should work great for you.
On the other hand, when you're ready to buy everything, I would definitely recommend buying it all from Turbo Tech Racing. Best prices and you can't beat Aaron's customer service.
well i am planning on getting different springs and i plan on get a timing chain. and i would be geting my car tuned!
Hey guys,
Just bought everything I need for a built head except more aggressive cams than the one I have now. While researching how I wanted to build the car, I realized the Comp NA stage 2 was the right cam. Now, I am really thinking to build the motor too. I found a built motor with a compression of 8:89:1 (built for turbo) and a new set of blower grind comp cams (#113250) for cheap. I will go Turbo, just not anytime soon. I plan to tune and drive the car with this built block and my built cylinder head.
Will these blower cams be OK until i boost? Can I put them in, adjust them with my adj. cam gears and drive the car fully built with no turbo/blower and still get great use out of these cams? If so, that's great and when I do go boost, I'll have the right cams already, that is what I am hoping you can tell me. Thanks!

Wait until you get the turbo before you install the engine. The 8.9:1 compression will cause the built engine to have less power then a stock engine. You'll hate driving it around N/A. Low compression sucks.
Thanks! That makes sense. Any info on the cams? What I was told last night was:
The turbo grind cams are designed to keep the cylinder pressure up
The blower grind cams are designed to basically get rid of heat
If that is the case, the blower grind won't work for me on a turbo motor it seems.

I would not do blower cams on a turbo setup. You will have no low end power. I have tuned a car with blower cams that was twin charged. down low sucked balls.

Turbo cams have less valve overlap(when the intake and exhaust valves are open at the same time) because the pressurized air helps force out the spent exhaust gasses. N/A cams have more overlap because N/A engines do not have any pressurized air to help evacuate the cylinder.
Gotcha. No blower grind.
Overlap makes sense. Here is what Comp Cams told me:
Only the turbo grind and the NA stage 3 grind would work with low compression and turbo. The NA street stage 3 will build up boost a lot faster than the turbo grind. In fact, he recommended the stage 3 cam over the turbo cam. What do you both think about that? I now also have a chance to buy a turbo grind for under 300 shipped vs a new stage 3 for 500. If I get more power out of the stage 3 obviously that's what I'm buying. Here's a link to the cams in case you gurus wanna explain the numbers a little

For a turbo setup I would go with turbo grind cams.
You have to realize that your either going to spend more money and have n/a cams for the time you are n/a, or your going to not have as much power while n/a so you can have the turbo cams when your boosted.

Exactly. Def. less power now and more power when I am boosted sounds better lol.. I'll check the link, thanks.
