Anyone know if jun stage 3 cams will work w/ skunk2 valve springs? will this setup cause any problems? thanx

 

no.
use either toda or portflow inner/itr intake outer combo

 

safer to use jun valves with jun camshaft,or skunk with skunk

 

Yeah I know it will be safer to use jun products together, but I already have the skunk valve train in my head....what I need to know is what kind of problems can occur if I install the jun cams w/ the skunk valve train or will it be okay even though it is better to have the full jun setup?

 

i dont care what anyone says, as long as its a quality product the valve springs will be just fine for jun 3's

 

Portflow is a quality product, yet the rates are a little high for JUN III, which results in premature cam wear and possibly breakage. Sorry but I will disagree with your statement.
It is BEST to run JUN components together, if you can't afford it and don't want to wait then... Just keep in mind you are NOT going to be covered if something does happen, and you will also run a higher risk of damaging the cams/valvetrain/engine by using a peiced toghether set up.

 

I dont think you will have any problems, but If you are worried find out who makes the Skunk2 valve springs. I doubt that they make them in house. Then ask this question again.

 

PITA I know, but I think you should swap them and resell the skunky schtuff.

 

DO NOT use skunk or jun springs with any high lift cams.
JUN springs barely clear 12mm lift and unless you haave the install height set
by a machine shop they will BIND and cause breakage which could result in a lost
motor.
Unless skunk has replaced their spring line, they cant handle anywhere near 12mm
lift so you definitely dont want to use those.

 

Wowz. I think I'd listen, that's the most I've heard from sgT in quite awhile.

 

Man so many mixed opinions! Sgt if skunk nor Jun springs are good then what would you recommend?

 

Uhhh...he already answered you.

 

sorry about that! my bad......I was looking around the net and found this:

http://www.importreview.com/reviews/JUN3vsTodaB.html

read what he says in #3..what do you guys think?

 

Both cams are great...and both are pricey. There's another comparo of Toda/Jun/ITR cams on that same site somewhere, and again I think the Juns win the peak HP honors. There's another comparison of valve springs around here somewhere too, shows spring pressures & coil bind clearances, I can try to locate that for you too if you like.

 

how about crower springs? the 68185 w/ their retainers.

 

what about skunk springs and crane stage 3 cams?

 

I had Jun 3s and Skunk2 springs/retainers running together for months. Never had a problem. I revved all the way to 9500 and still ran good. The only reason why dont run the JUNs any moer is because they broke into four pieces. So I never went back to JUN cams and just stayed with CTR. So to answer your question, yes, its okay to run Skunk2 springs/retainers with JUN 3s.

 

Are JUN cams easy to break?? Heard someone broke the cams even with JUN springs.
Has anyone broke ITR, TODA or CTR cams??

 

All you have to do is improperly torque the cam holders and any of the cams you mentioned will be at risk of breaking. The higher lift cams are at greater risk, but improper installation will take it's toll. As far as I know only Crower & Skunk2 have admitted to manufacturing defects and both have resolved their problems. I've seen photos of broken Crower, Skunk2, Jun, Toda, and CTR cams. I'd choose the cams you want based on price/performance concerns and disregard the horror stories. Just make sure yours are installed correctly and with the appropriate springs & retainers.

 

JUN3's require linear progressive springs.... I've had 6 friend's personally shatter their cams and heard of many other people doing so all not using the JUN valvetrain... Oh well it's a lesson we learned... I love Portflow, their springs are just too stiff for JUN cams... Good Luck

 

Under what circumstance when it broke, normal driving, when VTEC cut in or 9000+rpm?

 

Yea actually none of them were up on high end, out of my friend's atleast... Normal driving... light VTEC x-over then bam... Basically right under ~6000rpm... On a couple of the motors it cracked the sleeves etc...

 

id bet money the cams broke cuz the springs were binding

 

Yup, that's exactly what I think too... it locked up the springs full range of travel and SNAP... oops.. haha

 

Here is the test from import review about the spring rates.Enjoy
