From my understanding the JWT cams are better. I have no personal experience, just my opinion from doing my own research. GL.

yea thats what im hearing too about the jtws....i heard also that bc is like a crook or something like that i dont know how true that is but...

You can't go wrong with JWT cams. I have them and they are awesome!

JWT get JWT valve springs too

those stage 3 cams.... will the work with a stock internals?

They will, I'm running them on stock springs to 6800 rpms.  But they aren't available, mine were the prototypes.

The JWT cams and Nismo cams are very similar. The only differences are that JWT cams are a slight bit more agressive (not by much) and they are also cheaper. AS far as the BC cams goes, their stage 2 is more agressive than both the JWT and nismo but no one has really dynoed them to see how much better (if any) they are. BC is still trying to work out the kinks with the stage 3 cams because they were tested recently and found to actually lose a bunch of low end power and not gain a whole lot more up top than the other options out there. The stage 3 cams may very well be too agressive for this engine. Hope this clears some things up.

Nismo cams are made by JWT FYI...

thats pretty much what i been hearing and reading...im probably gonna go with jwt bcuz of the fact that they make nismo cams by contract and they are cheaper....i wanna keep my car n/a and run it on autox....thanks for the input

The truth is it's going to depend entirely on your setup.  From the sounds of it, a stock revving car, with a stock intake manifold, seems to benefit best from the JWT's out of the cams available.  But, take another car that is able to be pushed higher, and has a higher flowing manifold, and the JWT's would likely be dominated.  Cams are something that is entirely engine setup dependent, and you can't simply ask "whats the best cams out there?"

Yup, the header type can also make a difference here.

u mean like the type of exhaust header i have??  remember guys i dont kno much about headers im an ex mechanic that turned social worker...so my knowledge has become very rusty on these things

Yes, exhaust header.  A 4-1 shorty will perform differently than a 4-2-1 like the DC.

ok i put in the 4 to 1 headers nismo...with nismo cai...and that crappy tsudo cat back...i kno the tsudo is crappy and stupid loud...

go with JWT, they make nismo's and are less agressive than their own (hardly noticeable)....or wait for BC to finish up their work (they dont have a stage 1, only 2 and will be 3).   Stage 2 will be similar to JWT but sounds like they have more midrange, and stage 3 will be for race applications with more top end

im gonna go with jwt...I havent heard that many good things about BC and im more familiar with jwt then BC...also that jwt makes the nismo cams which i think is pretty funny

^this car is as real as ever..... so

aem makes the nismo intake

  thats some bs....cause i have the nismo cai....thats not funny

It's true man, many of the nismo stuff was outsourced to other companies.  The intake is AEM, the cams are JWT, the suspension is kyb/eibach, etc etc.

wow thats amazing...well for the suspension im good cuz i got the eibach prokits...btw i love them....so i guess the most obvious and logical choice would be JWT...its crazy tho how those parts are from other companies but nismo feels it right to charge crazy amounts for their parts...i guess they gotta make their money some how..thanks for all this info guys even tho i kno my intake says NISMO but it breaths AEM

let me shim in on this.  JWT, NISMO and BC stage 2 all have the same top end power more or less by 1-2hp but nothing u can feel to notice a difference.  the difference with theses is that BC has more Midrange hp across the power band, so it has best of both worlds.  I know this because i dynoed nismo cams and i dynoed BC cams.  Overall if your making a decision between nismo and JWT, then dont stress yourself, get which ever one is cheaper.

funny i was just gonna create a thread like this b/c i wanna buy cams but not sure which to get...im going n/a too so i guess ill look into jwt cams

its funny too cuz we both are form long island and drive red 06 spec vs....weird

I have the BC cams stage 2 in now for almost a year and I love them!! They feel alot better in mid range than JWT!! The previous owner had JWT in the car when I purchased it so I was able to try out the car for a week with these cams then he sold me the car taking out the JWT cams and I installed the BC stage 2!! I am boosted now and still love the mid and topend of these cams!! The stage 2 was originally dyno with a boosted spec-v with a 25hp gain! I still like the JWT but for around the same money I would def buy BC!!!

Noone they had to of dyno the cams to reference how to grind the cams!! I spoke with tech at BC and they told me they made 20 to 25hp with these cams on a boosted car!! Stage 2!!

Have you seen it?

Please read above for all the noon'es

He's about the only one besides me and a couple others that dyno parts, and he's not boosted.  VERY few people have dynoed any of these cams.  The claim that the Stg 2's make 20-25 whp on a boosted car has ZERO proof behind it.

Thats what the tech said  to me on the phone!! Are u calling them liars?

they also said their stage 3 made at LEAST 20WHP; i made nothing close to it; and lost so much tq its rediculous

I still have the Stage 3's on the car, and yes they lost massive torque.
