Are Cams worth it?

[focusedrage]

After searching around a bit I found that hks cams are generally regarded as the best. My question is weather they are worth the expense? Are they the kind o upgrade that is useful with better turbo and such things? As too the idle quality: what does that even mean? Will the car stall out? Will it sputter like a race car? Will increasing the idle speed slightly reduce the problem?

The small ricer part of me says a car that has a rough idle so that it sounds like a race car would be cool… but I imagine there is power to be gained?

Thanks

go with HKS... and get 264/272s! this will leave you with nice power gains and good idle!

 

[DirtyBirdRacing]

Do you mean 264 intake and 272 exhaust, wasn't sure.

if you are begining your build up meaning intake exhaust and ect no its not worth the money.

Agreed.

You need some mods to make the HKS cams worth it.

 

[harryb]

Yes they are worth the money. Look at what the people that matter run....Hot damn its HKS cams 9 times out of 10. Don't cut corners if you want a car that is right. Price and quality accompany each other many times in modding a car.

 

[larryd]

yes cams are worth it but not at the stage you are at.. you get cams for the car once youve upgraded your turbo and nearly everything else and maxed out your stock cams as I have..

 

[Enigma_Man]

About HKS cams being better, I've heard a lot of stories of other cams (webcams) being ground improperly, so as to require an adjustable cam gear when you get them.

A lot of people will reccomend HKS, because while they are more expensive, they are done right the first time.

As far as idle and sound goes, yeah, it'll sound cool like a race car It seems to vary car-to-car whether or not you will actually have problems with idling, but going with 264s on the intake or all around seems to help it a lot.

(BTW, this is all secondhand experience, my car's still stock, hehe)

thanks for the imput, seriously though, what happens with the idle? like if i went with 272s all around would the car stall? i was under the impression that the reason cars would idle badly was becasue the cams were designed to make real power at high rpms, and thus often idle speed would need to be increesed. This is how it is with pushrod v8s. is it the same for the 4g63? woudl i need a vacum resivoir? this is helpful

HKS is worth every penny. Eventhough web will replace the cam if it "crumbles" then there could be more harm made to the rest of the engine. I have never heard of HKS having any problems like web. The power is very close between all the cams available.

The idle will be an up down motion. It will sound like a race car and if you do not like that then there are combinations (stated above) that you can go with that do not have such a spiratic idle.

If you upgrade turbo then the power gain with cams will be worth it. If you stick with the T25 then you will not notice much on the butt-o-meter.

 

[larryd]

the idle all depends on the cams you get though.. Ive heard cars with HKS 262/272 and it doesnt sound anything like my car did with the crower stage 2 cams.. My car sounded like a big block V8 lobing at idle.

 

[blewbyu]

Is it true that after market cams are only good for about 20K miles berfore they start to wear down and loose power?

 

[LaserRST]

No... good oil pressure will prevent wear. They use the same materials on these cams just like the stock ones. Cams can actually create more power with wear... hence regrinds. This shouldnt be an issue. Cams for the 4g63 should be staged with your mods. The stock cams actually work awesome, unless your pulling some serious power, stick with the stock set up until the time comes for a higher revving higher demanding engine.

 

[focusedrage]

yeah at some point i will get a big28 or big28 killer so then i supose the cams will be usefull.
crower? are they better? any bennefits over the hks? thanks

 

[red91tsiawd]

i know the crowers are alot cheaper

 

[XTurboSpYderX]

I was kind of wondering the same thing... eventually I was thinking about 18PSI on a Big28 or a 28 Killer... would 264/272 set-up benifit me then?

 

[DSMkid14]

hmm..weird, im wodnering the same thing, only im gonna be having a B16G.

 

[candela]

Not really with those turbos. Youll need a turbo that will hold boost way up top... like to 8-8.5k or so. I know 16g/t28's wont hold much boost up that high. Look at Larry's, hes got an L2R and is just starting to br limited by his cams. Stock cams are great and go well into 11's

 

[candela]

especially 1g 5 spd cams, they are a little better than 2g's for top end

 

[XTurboSpYderX]

would there be ANY benifit to a 264/272 set-up with either of the aforementioned turbos?

 

[focusedrage]

i am tryin to build the car for road racing... so i dont want lag in the turbo, cams will impove top end power? will they reduce low end power or torque... i would want to go with 272/272 cause i havent heard any reason not to

 

[L2RTSiAWD]

Yes you will always gain at least some power above 4500rpms with HKS cams even if you only upgrade to a Big28/Big16G turbo.

 

[XTurboSpYderX]

cool... so you will get SOME gain... but you would need a rather LARGE turbo to utilize the cams to their full potential??

 

[L2RTSiAWD]

Really it's like the bigger the Turbo the bigger the gains.

I mean look at RRE site. They gained 37peak HP from cams on a 16g.

i also agree. they only make a noticeable difference if you have massive hp on the engine....I'd wait, and get the million other supporting mods first. just my .02
