I have a 97 2.4, and I've looked and searched everywhere I can think of for aftermarket cams, and I can't find anything exept for the secret cams. First, where can I find aftermarket cams for my car, and second, If I go to all the work of putting in different cams, I want to put in some aggressive ones (screw drivability) in order to get the biggest increases. I was wondering how agressive the secret cams are compared to something like a stage 2 or 3 aftermarket cams. I'm leaning towards doing the secret cam swap, but if I'm not going to get a lurpy idle, and much more power like you get with aftermarket ones, I'm not sure it's worth the time. The only thing I can find is for the Eco's, nothing for the LD9's (aftermarket anyway). Any insight would be appreciated because I might have a small chance to buy some "secret cams" at the end of the month reletively cheap from someone.
I don't know alot about cams but keep hearing about the W41 cams and that they are alot more agressive than the secret cams which I believe are out of the 2.3 HO/LO.

as far as i know jbodyperformance sells an "aftermarket" set of cams...i have heard pretty good things about them. they are pricey too
"sometimes the respect is more important..."
read the sticky... I think there around the stage 1 area or street cams
So aparently it sounds like this is one of those things, the eco guys have over the 2.4's then. I'm still not sure what people around here consider pricey. Basically, if it isn't blaintently obviouse the cams are in the car with the secret cams (idle, and noticable ecceration increase) I'd rather just save the money and get something that REALLY works. There's gotta be more choices than that you'd think.
Well, I've been researching this a bit more, and they are the same as stage 1 street cams. I'm just wondering if anyone has had any luck with something a little more agressive, and still be able to keep the power increases below redline enough to be usefull. Abviously stage 3 cams (if they make them) wont come on at all until after the rev-limiter so they would be useless. Stage 2 (street/strip) cams are more what I'm thinking about, but I don't know if thats going too far or not, even if I can get my hands on some. Sometimes I forget i'm not building a 350 small block, I still tend to think that way sometimes.
LZM (livid) does a nice grind for the LD9 i'd message him and see what he says.
watch for flying sparks!!!
I think mantapart has some stuff, but not everyone has had good experiences with them...
Oh, yeah, and if you get agressive cams, don't forget the rest of the valvetrain. you'll end up with your valves trying to make love to the top of your pistons (as someone else put it).
You can get cams from comp cams, jbodyperformance, lzm, and i also believe crane but i'm not sure. Your best bet would be to talk to someone at one of those company's that knows what they are talking about, tell them what you have done, what your going to do, and see if they can help you decide a good grind. Also, the more agressive of a grind you do, you are going to want to tune your car to get the best results out of the cams. Some people buy stage 2 cams, and actually hurt their performance because their car is not tuned for it, so their 1/4 times actually get worse. Stage one is normally considered something you can just drop in without tuning, and it will help out performance. You should still tune them to get the best result. stage 2 a lot of times hinder performance.
HO cams
Ld9=Stock
Secret=Stg 1
Ho= Stg 2
W41=Stg 3
TaetschZ24s "BIG" Cams= WHO THE @!#$ KNOWS WHAT STAGE!!!!
Oh this is all given with some sarcasm
"Stages" are gay.. real specs are where it's at.
W41 cams probably won't lope since the W41 was a production engine. Lope comes from valve overlap (lots of duration). I'm not sure on your 2.4 TC engines but i know the 3.4 DOHC guys can play with cam timing a little bit to change the power band.
Regrinds may also be an option but on OHC engines that could get tricky since you lose base circle.. some kind of shims maybe?
JUST get a pair of secret cams, Kevin Bordeaux sells pair on a regular basis for 125 $ you cant go wrong. Hybrid/Secret cams give decent gains., and KEEP your CEL off !
BUT remember it not the cams that cost alot, it is the labour, most Canadian shops charge around 540 $ to install a set of cam on a 2.4, and you need new gaskets, maybe a few lifters which are in @!#$ty condition, tenshioner shoe, sometimes a whole timing set, ect ect. !

Just so people aren't confused, Monkey isn't making a comparison to JBP or any other brands "stages" for cams. HO, W41 and the Hot Grinds 1 & 2 cams anihilate any aftermarket cams for all-out performance...unfortunately they won't work on your stock valvetrain or stock ECM.

It may be a production motor, but it is more of a production "race" motor and is prone to loping with it's longer duration.

Brian, good to know.
It's been years since i've heard one run..

Yeah i had a few 2 drink and was trying to make fun of Chris Taetsch hehe....
Do HO cams have a decent little lope? I have some but I've been thinking more and more about W41 cams.
well where all want Specs hey.....
Intake .450 lift 232 dur.
Exhaust. .430 232 dur.
BUT my Rocket Parts ECM did a nice job of "calming" them... but they where choppy i guess................. Tom liked them i guess.
If you get a W41 LG0 to run at 1000 RPM its really not to bad, a LD9 with them..... i guess would be choppy, but really its only 218 DUR as apposed to the LG0's 210, its not till you get to the Comp cams "hot grind W41 cams" 226 Dur that it starts to chop... but it sounds cool.
i tryed my cams at 0/0 +4-4 and -4+4.... nothing tamed my cams... my GTZ is getting a set of BRAND NEW W41 cams i got from work.
My Z24's getting the cams out of my GTZ, when i had them out the first time and meshed them, came out to a PERFECT .410 lift.
HO cams idle nice and stock.
for the money, you cant really beat HO\W41 cams.

My understanding is that anything more agressive the the secret cams (actually LO cams) require you to replace the housing (HO carriers) or the lobes will tap. Even using HO cams aperently require this. I guess I could always just get a set of adjustable cam gears to tune in a little more overlap, although the problem with that is since It has a timing chain instead of a belt, you can't just pop the hood and tune them, hopfully someone has done the work already so it can be a one time setup.
Yes, GM has done it, they used to sell +2-2 and +4-4, look in to "Rocket Parts" that will have the info you want.
One way around the problem with the HO cams is to have the cam towers bored out to the bigger lifter size, then cut and drill the intake cam to accommodate the LD9 power steering set up.
Then use HPT to delete the CPS code and run it one batch fire, like older Quad-4's.
