Choosing Cam for D16z6
Im pretty sure I have it narrowed down to 3 candidates.
The Comp (ZEX) quiktyme stage 2
The crower stage 2
or the crower stage 3
The question is how long will my stock valvetrain last under the abuse of the big stage 3, even at stock rev limit?
Will i have a few months at least before everything is fatigued? Anybody running any of these cams with nitrous?
As always, anybodies opinions are valued. Im open to ideas. I looked at gude too, but its more then i want to spend. I can get these for $321 or less. I plan on changing the valvtrain, but not until I have some headwork done, which isnt right now.

Re: (94SiHatch)
All right man, I would say that your stock valvetrain will do ok, as long as you are not revving any higher.
If you are, then get new springs, retainers and anything else new up top followed by a nice healthy dose of wideband tuning.
I would not do Zex cams, I would definantly use the Crower. They have a much higher quality, compared to the Zex cams.

Re: (conesmasher)
well the plan is to install the FPR, Cam, and Cam gear then tune it all on the dyno with the nitrous.
im trying to be careful with this motor, its going to be a couple months before I can start building the new motor.
I dont even know what to expect. whats the average z6 dyno with basic bolt-ons? I/H/E, no power steering, no a/c, and a 6 oz crank pulley. Also whats a good power limit for stock internals? I want to get as much power out of the bolt ons as I can, then just max the stock internals with the bottle. At least until I can do something about better parts.

How did you come to this conclusion.
I'm sick and tired of people giving their opinion when they haven't even done any research on the subject. You are just ASSUMING that Crower is better because of the name it carries. Take your assumptions elsewhere.

Re: Choosing Cam for D16z6 (94SiHatch)
Im in the same bind either the Zex 59300 Stage 2 or the crower Stage 3 I can get a helluva deal for the 59300 and every one raves bout this cam.. I too am a N20 Junky with my Zex kit I think ill go with the zex cam just becuase they say it complments the the N20 very well.... where the heck is Holidea Fl? Im up here by Gainesville...

Read this thread. https://honda-tech.com/zerothread?id=756098
It is about boosting, but the same concepts apply to nitrous.

i do not think that stock springs and retainers can handle that period.(stage3) And i had a cower cam, i do not know if this was due to faulty installation or not but non the less is broke. not saying there product is bad but it can happen and the your fucked. but get the stage three with new valvetrain and that would be bad ***

Out of these three the crower stage 2 get my vote.The stage 3 is the biggest off the shelf cam your gonna find for the D16Z and without springs and head work its kind of a waste...IMO,the best choice would be to stick with the stock cam and upgrade to the stage 3 when you do some head work
btw...stay away from a Gude,I had one,performance wise,I really couldnt feel a difference,it only added .01 and 1 mph to my ET and its a regrind...blah 
but if it was my car,I would spend the extra money and get a Crane instead of either a crower or zex

Re: Choosing Cam for D16z6 (D-Man)
Crane doesnt make a z6 cam I dont think.
I think im just going to get the crower stage 2. It gets better reviews, and I would need to chip my ecu to properly run the stage 3. No big deal, it will run better day to day, should still lope ate idle though.
They are cheap enough I can get the stage 3 later, when the engine is built to perform with it.

Re: Choosing Cam for D16z6 (94SiHatch)
I have had personal experience with the zex stage 2 cam and I love it. I have also heard good things about the crower cams too. I would definantely recommend not getting the crower stage 3 without a ported head and a full valvetrain upgrade. So i would say for your setup either of the stage 2 cams would be nice. I am running the zex cam in my y8 with stock valvetrain, but I will be upgrading probably within the next month to zex valvesprings. Everyone that I know of with the crower stage 2 cam seems to run the crower valvetrain though. Oh btw my zex cam makes power all the way up to 7400 rpms where I have to shift because of my stock valvetrain. I'm sure it makes more power past that, but I am not gonna rev that high for now. Oh and on my friend's y8 with a built z6 head with full crower valvetrain the zex cam made power up around 7800-8000 rpms.

Re: Choosing Cam for D16z6 (BauleyCivic)
Exospeed wants a core, and ive seen dynos of exospeeds z6 w/ bolt-ons and headwork with thier cam and it still only made 127whp
Im shooting higher then that, hopefully. At least im going to try.
Im sure they are all good cams in thier own right, just gotta go within my budget, and the crower specs are a little more agressive then the 59300 zex cam.
http://www.hadamotorsport.com/....html
Thats where im looking at my specs, because they standardized most of the measurements, to make it easier to compare.
Im definitely not getting the stage 3, no need for a 1500rpm idle in a commuting street car.
Stock z6 specs: advertised duration 224/228
Intake/Exhuast
208/192@.050
Gross Lift
384/370
Crower Stage 2: Advertised 276/255
230/204@.050
Gross Lift
427/432
Zex 59300: Advertised 260/268
220/216@.050
Gross Lift
455/430
The zex and crower look pretty even to me, but the crower should cram more into the cylinder. However the zex cam has more exhuast potential...which is good for nitrous. Its probably gonna come down to whether I have $230 or $320 when i go to order the cam. But they both look good.
Has anybody played with the cam timing with either of these cams, save me some time on the dyno, give me a better starting point then zero. It cant be as complex as a DOHC.

Re: Choosing Cam for D16z6 (94SiHatch)
I just took out my zex 59300 cam outta my d16 and i had all the bolt ons and it really made a diffrence. When you go to put it in your expecting like godly results so you might not notice tons and tons of power...but when you take it out you'll notice how much slower it is for sure!!! zex pulls good too with vtec...little noizy with stock valve train dont rev over 7200 until you do springs. Good deal for the price!
