I'm interested in purchasing this for my car, but am having a hard time locating prices. Does anybody know how much it costs and possibly an estimate on installation. Thanks

 

Go for the Portflow inners and ITR outers on the valve springs. Call me or IM me for pricing. Regarding the JUN3.. good choice. They are awesome cams. I'd say call Titan Motorsports in Orlando, FL for pricing. Ask for Wes or Bottle. (407)977-9732.

 

why wouldnt Jun Valvesprings be recommended for a Jun Cam setup? rather than a mix and match concoction.

 

its just about price

 

jun stage 3 cams 440 each
jun cam gears 160 each
jun valve springs 300
crower ti retainers 130
labor 325

i hope this helps

 

Jun recommends their valve springs just like Toda does theirs and Crower does theirs. Everyone wants you to buy the brand name. Portflows work excellent. Mike's been shifting over 9000rpm for a while now. No problems..

A set of 8ITR's and 16 Portflows can be had for less than $150.
compare THAT to JUN pricing.

 

You can call JUN directly, or you can call moderngarage at (801)-262-4605, and ask for Christian. Tell him Jonathan told you to call. He can give you pricing for all of the JUN goodies. Moderngarage is a dealer for JUN. You can also check out the website http://www.moderngarage.com

As far as the portflow springs are concerned..... I don't really know much about valve springs. All that i know is that I have had the JUN 3s and their springs/retainers, ecu, and cam gears. And I have had no problems for the 17000 miles that I have had them in for. I bet the portflow way would be less expensive though, but there won't be any problems if you went with the JUN springs.

 

How did your car run with those cams? Anybody run CTR pistons with JUN 3's here.? My head is milled 20, I'd like to upgrade to those cams some day.

 

Mike, why did you choose Jun 3's over Toda B's? I'll be upgrading cams soon and am looking for worthy opinions. Drew over at Musical Touch mentions you quite a bit. Thanks, Ken
BTW it'll be in a 99 Si w ITR header, E, I, etc...

 

He probably wants more top end power with a smooth idle. Toda = mid range w/ rough idle.

 

How 'bout that JUN ECU? Is it reprogrammable? Or do you need to "tweak" it with a V-AFC or something similar (in which case, why bother - why not tweak the stock program with the V-AFC)?

Eh?

400 posts later - I'm still ignorant.

 

JUN III are great cams, and they do have plenty of midrange along with the sick top end. The only bad thing about the cams is this, the over-lap is huge. So youre bleeding off compression. For me my GSR bottom end is hurting me (10:0:1). JUn recommends 11:5:1, so I went with CTR pistons, which will be installed this week. Also their ECU is some serious $$$$$, about 1800.00 for obd-2 cars. Your better off getting a Hondata or custom tuned ECU chip (There are genuwine JUN clones floating around). JUN III cams usually have more torque than toda Bs' or Cs and if tuned right can have the same midrange effect of Toda Bs' and way more peak power. Compression is the key with these cams!

 

Toda's having a rough idle is a myth. Mine idle very nicely.

So far I have 190 hp and 135 tq at the wheels - untuned. I should get more in the future.

 

Well from my experience JUN idles much smoother than Toda. The Toda's may not exactly be "rough", but it is rougher than JUN.

 

Why does everyone do this?

Is it money? Got the $$$ for the parts and the labor to install them but not the dyno time?

WTF is that?

 

Well dyno time isn't cheap. 120 bucks an hour. You usually need at least 2 hours of dyno time to get it all tuned in. Maybe the guy doesn't have time or the money. Givem a break man! Not all of us have money trees in the backyard!

 

hehehehe JUN CLONES
sounds like something in my car
as for the v springs
Toda requires them because they have 12.5mm lift and there arent many v springs that allow for that much lift
Jun has 12.0 and i guess the .5mm is all the difference in the world
also I know toda has a rough idle but it depends on the ECU that you are running
my Juns idle fine but sometimes it wanders a little but who cares
Im never at idle anyway

 

Because *****-head - I recently changed my entire bottom end and the new compression has changed the a/f ratios around. I had to break in my new pistons and bearings first - and just did a quick pass to see what effect the hi-comp pistons had.

So you get back to you since you're implying you know it all.

Just like your avatar, "Lay'in the smack down on your candy @ss!"

 

Hey guys, just wondering if Crower 63402(not 63402A) would go with Spoon 0.4mm head gasket & CTR pistons. Will detonation occur??? Please refer below for my other mods.

 

It depends on what octane fuel you use/intend to use

 

Normal pump fuel, like Shell 92.

 

The JUN cams do idle perfect, and with the JUN ecu they are tuned very well. I don't think that anyone can tune the JUN cams as well as JUN can. Yes, the ecu is pretty expensive, but in my opinion it is worth it. There were some dyno charts way back a few months ago of a guy that had the JUN ecu and then tried to fine tune it with a vafc, but couldn't get anymore power out of it. (I think he got 199 with JDM pistons (11.1:1)) Anyway, the worst thing about the ecu is if you make any drastic changes you have to send it back to get it retuned.

I'm not saying that you couldn't make good power tuning it with something else, but I just think it will be more difficult. I think the only thing I did on a dyno with mine is the cam gears. It is just personal preference, but I personally am very happy with JUN's tuning.

 

Regarding tunning go to the Tech category and look under the thread "ECU Programing?". We just had a big discussion about that, maybe some of you guys might put some of your comments.

As to the JUN 3s, they are a very good cam, but unfrotunately the primary lobes are not as aggressive as the Toda Bs, which at the track is very limiting if for some reason you drop out of vtec, since you will have a drop of aprox 15whp to fight against. With Toda Bs this is not the case since the power band seems to be more even in progressing, just like your GSR power band. And the Toda Bs are very similare in the top end to Jun 3s, if not almost the same. I personaly have the Jun 3s, but for serious lapping I would probably recommend the Toda Bs.
