I searched through the forums and could not find anybody comparing cams. Pretty much everybody does the 2.3 cam swap in their 2.4's. Before anybody jumps on me about this I must bring it up. RSM says their cams give a 15hp increase. IF this is true what kind of numbers would you see from the 2.3 cams? I know, I know never buy from RSM they are theives. But I'm just wondering what other companies out there make performance cams? I'm wanting to build a NA 2.4 don't really want to boost it. I might as far as one day get nitrous but that would be much later after I did a few more things.
My car has two speeds, fast and faster.
you could always find out the specs of the RSM cams or the "secret" cams; call up crane or comp cams and have them make you a set. not that long ago i bought the RSM crank pulley, and to say the least i will never do business with them agian.
Ill make a sig someday
the rip off RSM cams, JBP cams, the secret cams, or get some camblanks and grind your own. the specs for the secret cams are probaly in that FAQ type thing thats atop of this forum. and JBP lists there cams specs on there website.

Thanks for the info, but for if I was to stay NA would I see a big enough increase in performance for the price? And which cam company should I look into for best results in staying NA?

u cant get cam blanks i dont think u can

LZM (
http://www.levelzeromotorsports.com ) offers the same LD9 cams as JBP much cheaper... ground by the same guy. The specs on either website arent accurate, since the grinder is a tad paranoid... but I will attest to their 22hp gain, had them in my old LD9 and ran 14.996@90.44mph with the other basics (HO intake, MSD, Header, 2.25" exhaust)

my personal opinion is that the only time to get an off-the-shelf cam grind is when you are going to be staying out of the engine otherwise.... If you're going to run stock head, stock compression, and stock redline, and don't ever plan on changing those, than some of the ready-made cams out there will work just fine (with proper tuning of fuel, AND TIMING!!).
However, if your plans include possibly a ported head, or higher compression, or raising the redline with something like HPTuners... than my advice is to have the head flow-tested, have all the other details at the ready, and then call a cam company for a grind specific to your setup. There's too much of a "one size fits all" mentality around here when it comes to cams. A set of stage 1 jbp cams will work in a ported head, but won't make as much power or even have the driveability of a cam ground with the specifics of the engine in mind. To be frank, I'd much rather trust someone who's been grinding cams for decades to come up with whats best for my motor in a lengthy and descriptive phone conversation, rather than just grab whats available.
And like i mentioned earlier... tuning.... don't know how many times i have to say it, but tuning for the cams is important even if they "work with the stock computer". You can't just pop a set of cams in with stock ignition timing maps, and stock fuel curves, and get optimal results. Will the engine run? Sure. Will it make more power than stock? Maybe... Will it be running to its best potential? Most likely not. There's a right way, a way that works, and an utterly wrong way to do everything.... My advice is to do it the right way the first time, because that way almost always ends up being cheaper than the other two.

Not sure what you mean by 'off the shelf grind', but the problem is that often, a custom grinder is not the best guy to ask. He is a cam grinder, not an engine builder. He knows how to grind a cam, but ussually not that much about putting together the right combo, which I think is what you are referring to. Lift is lift, and duration is duration. The numbers tell 90% of the story, and if you know what you want to do, then its easy to make an apropriate cam choice. Your first choice should be determining what your desired powerband will be, and choose your mods to support that. Just remember, bigger is not always better, especially with out OBD2 cars. It is always better to undercam, than overcam.
owen,
then what is the specs of those lzm cams? i'd like to know and see if i can just get some ground by crane (just trying to see which will be cheaper\
No body knows the actual specs of the cams other than Geoff at Colt Cams (who grinds the cams for both LZM and JBP). Why? Because he's paranoid of people doing what you're doing.... taking his designs and grinding them elsewhere.
$500USD for cams is a steal dude, I think I paid that for my LD9 cams and LZM is my "sponsor"... then went F**** when I wanted to sell 'em since LZM had dropped their retail price.

Which is funny, because you don't need to know the numbers to copy them. You need the actual cam.
Why he won't discuss the duration is completely retarded.
$500 is still too much for a set of perf. cams, unless they're billet (which you don't want for our cars, anyway)
Those ones on ebay are priced the way cams should be.
The shops charging $700 for a set of cams are making $500 profit.
Anybody know the phone number for LZM? Ive emailed them, but nothing back yet.

Im thinking about trying these cams.. Ive emailed them and they responded very quickly. I asked them if we could use these cams with stock 2.4 lifters, springs and cam towers and they said yes.. They will throw no codes.. So I might take their word for it and just try them. If I hear a knocking coming from my towers lol I saved my email where they said they will work with stock size valve train

Make sure that they have the HEX key for the power steering on the intake cam...
Knowledge about everything and yet an expert of nothing!!
