No problem guys.
The biggest thing I learned is what different cam company likes best....lift or duration. JUN is by far a duration company. They have much more duration than others on the list but hella less lift. Good for people running high dome pistons but adding lift really helps more IMO.
As for mixing/matching cams. I wouldnt do it. Maybe a JUN II Intake/JUN III Exhaust but still yet they are made to work together as a set. If there was duration/lift/power to gain by mixing and matching then they would do it themselves.
Another thing I learned.....I was really underestimating the JUN II cam. That is a hell of a cam that almost no one uses(Joey does I think). It is closer to JUN III than I thought it would be. Probaly just a little less power over 8200rpms but mainly thats it!

Yes he did. You may be able to find the post on Honda Tech. I think I've got the link saved somewhere, I'll see if I can find it.

nice compilation Sammy ! , if you hear of Jun cams or most other cams causing binding of the springs, it is almost always an installation error, where improper installed height was used or not checked. Sometimes the wrong springs are used with the wrong cams, but usually it is a problem with the installed height.

im just curious, have anyone dyno skunk stage 1 vs ctr/itr cams? Do both of them make good mid range power? To me from looking at the specs, it seem like skunk stage 1 will make more power since it has more lift and dur. ? What you guy's think ? dyno polts will be excellent thank you!

Anyone know if the Skunk2 Stage 3 cams will have the same problems I've heard the Skunk2 Stage 2 cams have had? I'm talking about the lobes on the shafts wearing out after a while...btw make this post sticky!

This page is a sticky at the time.
I have not heard of any problems with the "new batches" of Skunk2 cams. Skunk2 admits that there were wear problems a few years back with their cam but I have not heard of anyone having a wear or breakage problem ever since the "new batch" came out. Atleast I have'nt heard about it here.

My two cents:
1. Kick ass research. Way to go!!
2. I'm sure that most of you will know this, but for those who don't.
Since the max flow through the intake ports is determined by the port geometry, adding lift will only help till the port flow is maxed out. After that any extra lift won't help(unless turboed). Whereas adding duration will always increase the amount of intake charge flowing into the cylinder, regardless if the port flow is at its max.
Just something to consider for those without head work.

the people that break cams are the ones who dont have a clue were the valves need to be lashed at or what spring to run not knowing that info will result in binding for sure.to much spring pressure.

which cams would be good to use in my ls/vtec engine. I have the stock 1st gen b16a cams and the vtec engagement is very mild, in sound that is anyways.
I was thinking of just changing the intake cam but I want to find one that will "POP" the loudest when VTEC engages.what makes the "POP" louder lift or duration?
please help me. thanks, Daniel

OMG.
You dont want pop...or a noticeable transition. You want a nice smooth transition when you hardly know that VTEC.
Unless you want to just have your car sound good and not have it make power.
Look at the post below this one for LSVTEC advice.

It is not sticky anymore becase it was not getting a lot of hits and most of the regulars have it in their personal files. Make this post a favorite and it all you have to do is go to your "Home" and there is the post.
Plus 4 stickies is too much in one forum.

Eric, I answered your questions via phone but will post anyway.
Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec) measured at 1mm of lift
Int-243 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift
Skunk2 Stage 2 measured at 1mm of lift
Int-266 dur. / 12.3mm lift
Exh-262 dur. / 11.8mm lift
Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec) measured at 0mm of lift
Int-278 dur. / 11.5mm lift
Exh-280 dur. / 10.5mm lift
Toda Spec B measured at 0mm of lift.
Int-295 dur. / 12.0mm lift
Exh-285 dur. / 12.0mm lift
One thing that is not compared is the Primary and Secondary lobes. TODA has traditionally used much larger Primary and Secondary lobes with their Spec B and Spec C over any other cam producer. These lobes provide larger off-VTEC gains. Skunk2, JUN, certain Crower cams have OEM or similar to OEM primary and seconday lobes and dont offer the midrange power of the TODA B and C.
Now for the real-world power gains.........Well TODA will give lots of midrange power and not so great top-end power. Although the specs are different, TODA B's give just a little more top-end than a TODA A. In a standard B16A2 they will gain around 25whp over the current set-up if the header is good and tuning is good. Add things like an ITR Intake Manifold, bigger TB, test-pipe, large exhaust, etc and the gains will be a little higher.
Skunk2 Stage 2's will offer much less midrange than the TODA B's but they are much more aggressive on the top-end. They offer tons of duration on both cams and good lift as well(sounds like JUN ). These cams will usually net around a 30-35whp peak gain with the almost-needed ITR Intake Manifold, large TB, etc.
I like both. They are my favorite two cams to be honest. However, I am a sucker for midrange power. I am an autocrosser who drives his car daily and was always wanting more midrange out of my B16A2. That is why I am more of a TODA fan. Plus in the days of JUN and TODA you had to choose one side or the other!!
Jerry will probaly favor a set of Skunk2's over TODA's. The Skunk2 Stage 3's are a very nice road race cam. They use a very low VTEC cross-over(compared to a TODA B or C!!) and have the most top-end power. Talented drivers that can keep the motor over 6500rpms at all times will like the Skunk 2 Stage 3's. I am an autocrosser and would like to ride 2nd gear all the way if I could, therefore I like a little midrange. TODA C's are nutty on valvetrain and fuel so the B's are my favorite cam.
I have told a ton of open-track day guys that Stage 2's(street) or Stage 3's(trailor) are the way to go. I also tell the autocrossers that Toda B's(street) or C's(trailor) is the way to go. Now with the TODA/Ericks Spec D's out....who knows. Thats a lot of stress on the valvetrain though! The D's(if I remember) are like a B/C off-VTEC and a Stage 3 on!!! Thats nutty.
The choice is yours(although you already made it) but from what you have told me, you want the midrage and TODA B is the way to go.
