my build thats almost done
well i might aswell post some pics lol
Jun III
excedy 8.5lb flywheel mmm
springs and retainers
block
pistons mmmm compression
its together and i cant wait for some warmer weather to start tuning it
valve covers a bit weird but i thought it would be funny
nice bro lovin the valve cover
thats the most awesome valve cover ive ever seen
thanks lol i've seen some really good airbrush stuff that puts this to shame though i think its fuckin sweet though glad you guys like it
that vc is sick, that engine is like a wolf in a sheeps clothing, soft cover harnd internals
Nice stuff! What compression are those pistons?
There mahle 11.5.1 CPR pistons I've got about .025 off the head and block together I should he at about 12.0.1
Damn nice build and VC is SICK!!! Very should I say pepto rific!! LOL
Work in progressneed slicks!
Good times! Keep us updated!Originally Posted by 2.0lef_itbs
nice build man
you should pick up a set of pro 1's or pro2's and make another 15 to 20whp those are great cams but there is always better.
Pro1's are that much better than JUN III's? I thought Jun's were supposed to incredibly nasty as far as lift is concerned.
Trend settin'
The skunk 2 have 12.6 mm of lift with 264 duration on the intake and the exhaust has 11.9mm of lift at 264 duration.
The juns are 12mm of lift and 11.5 mm on exhaust both with 304 duration.I don't think there's going to be a.15-20 hp difference between the 2 cams.there 2 different cams aswell skunk 2 are more mid range power where jun is more top end
no itbs?
No itbs was thing about it. to much work have to make them and then tune for hours to get them to work right.then home made ones usually get out flowed by most after market intakes so I got a 70mm bbk throttle body. I am hoping for low 12,s with this motor
let me guess for eg?
89 hatch
you can only go really fast int the ef chassi lol
ef,you must be a jdm lover haha.
My research shows, that the best overall cams on the market are S2 Pro series cams. If you want peak numbers then Rocket Motorsport cams are what you want. Jun cams are good, but they are old. So there are better profiles now. With that being said, Jun cams are still good cams, just not the best out now.Pro1's are that much better than JUN III's? I thought Jun's were supposed to incredibly nasty as far as lift is concerned.

Lol yea rocket motorsports looked good.I still wanted to go though aircare around here not huge primaries but decent sized.I might look at rocket motorsports when I put the gsr head on it in the next couple of years
my bro actually made more power with the jun3s than pro1s....go figure...
sure thing whatever you say man i've only seen it happen plenty of times i never said they will make 15 to 20 peak whp but they make more power everywhere over the jun 3's when setup properly. pro 1's and 2's make more power down low and up high compared the the jun 3's and make more torque along with having a better torque curve.
but if you don't believe me you can gladly try it yourself. or i'll give you the phone number to the guy that has done numerous cams test with rocket motorsports skunk2 crower jun endyne and every other cam on the market thats worth a crap.
that can have alot to do with his setup or the person tuning the car the pro series cams need a nice intake manifold throttlebody and header to perform really well.
well at one point adding bigger cams wont help.
the head can only flow soo much air unless i get a port and polish but that wont come for awhile but i am still i couldn't see add no more than 5-10 hp with the difference between the cams these days. i wouldn't mind seeing charts if you dont mind or contact info so i can see charts
^^^^^^^^^
he was running an endyne head, with skunk2 intake and hytech headers...it was tuned in NC...by some shop name RLZ or something like that....my point is that the Jun3 are still good and will make some good power....every motor is different..bigger is not always better..
i completely agree but there are alot of different aspects that could cause stuff like this and in every setup i have seen the pro series cams have made more power everywhere when degreed in and setup as they should be.
I just want to go fast!
don't we all lol
Waiting for my vibrint tensioner and six puck act clutch
bazooka bumbble gum comic spark plug cover?
Dubble bubble.spark plug cover
Reliability, daily drivable, and great power (for usually a cheaper price). The pro 1s and 2s would be my choice. but then again, i have never driven a car with JUNs, so I guess I cant talk.
The guy I bought my head off of put pro 1 in his type r and said he would have rather had toda B.might be to much cam for a type r .
lol. Nice build man! Lovin' the valve cover!
“When convention and science offer us no answers, might we not finally turn to the fantastic as plausibility?” Spooky
Damn sick as hell!!
I can't wait to fire it up
^
YEA!
I know that feeling..AWESOME
This has alot to do with it.
In my opinion, if you are running a stock head or very mildly ported head then the S2 pros are a better cam to run. The larger lift allows more air in but the shorter duration allows for more quench time. I have been happy with the power of the S2 and they make good low end power. We have made over 200whp with 1.8L, stock port head, and ebay header.
No matter what cam you run you need to degree them in for your motor. I have not had a chance to test this yet on the dyno (I always degree the cams in out of the car) but I would like to see what the difference in power is from just set to 0,0 and when degreed in. Good luck with your setup.

For the Jun3 specs you posted, that duration is the adv. duration. Actual duration at .05 is closer to the 265 mark. I like to refer back to this chart http://hondaswap.com/reference-mater...m-specs-28669/
The pro2's have .493" lift on the intake versus the .472" but the Jun has 265 duration versus 258. The exaust cams are very similar, Jun .452" lift, Skunk .458" and both are 265 degree duration. Based off those number I'd say the Jun might make a little more power, but the fast ramp design on the Skunk Pro's is not factered in by these numbers. This is why the Skunk Pro series makes more than every other camhttp://www.skunk2.com/images/diag_ys2cams_lrg.jpg. Yes at .05 the duration is the same but the duration is so much more everywhere else. Jun3's should make more power than the Pro1's though, no matter what. Thats just not a fair comparison imo.
Your Jun3's should still make very nice power and since you have them there's not much point in getting something else. Just trying to pass along some info for you. Ive been researching cams for my H22 and tried to talk myself into some BC's cuz they are so cheap but the Skunk Pro's will destroy them. I really like the VC as everyone else has stated, gets my creative juices going for mine. Im thinking bright orange with some garfield clippings.
As I said thats the advertised duration. Ive never understood why cam companies even list that information at all.
A good read that I found last night with just about every B series cam spec(except the Skunk Pro's):http://www.ek9.org/forum/resource-ar...s-engines.html
