Ok I remember reading about an article with cams. What i want to know is: Do I have to upgrade both cams or will one be good. I would like to know what cam to upgrade as well. I was reading about people only installing one cam and tuneing for pretty much the same gains.
Mods listed below.

someone correct me if i am wrong....but the intake cam is the one that yields the most performance gains

how much are u planning to spend on cams? i would suggest you to get the skunk2 stage 2 cams. they're the best cams for the price.

I have heard that the idle is not very good with them. Correct me if I'm wrong.

I'm looking for optimal gains with a stock like idle.

As for budget I'm not too concerned. I will be willing to spend up to $1500.00 for everything and I think I can do the installation myself.

I'm assuming this will include a valve train upgrade.

Go with the JUN Stage-3. I have them and I love them they have Stock idle and they have power to 9200rpms. Trust me go with the JUN..........................Just my 2 cents.................................

I suggest you check out my cam article on that other board I moderate at that I can't link here simply because the answer to your question is too long to write and the article answers it.

the article is at a website that has the words team and integra in it the address.

basically, in short form, the answer is for an non ITR cam, you need to get both. You can get away with just an ITR intake cam and valvesprings but the power potential is much less comapred to when you get both ITR cams. There are B18C1 with stock bottom ends and both ITR cams making 200 whp daily driven but they have the right engine package and proper tuning too...not just the parts....it's the combination they work in and the tuning.

you really have to also consider your CR. cam spec dictates CR.
I cover why in an article in a site where I moderate that has the word honda attached to the word vision in it in the tech review section. Again a long story...not a quick snappy short answer like you are getting from the others here.....please read the article.

Lastly, the cam you choose depends on your power goal and powerband location needs....I cover that in the team cam article....

hope that helps you out....

Plain and simple, JUN Stage3 and Skunk2 Stage2 are almost the same thing, you wouldn't even tell a difference. I'd buy Skunk2 mainly because I like the complete valvetrain system they have but JUN is also VERY good. Just depends on what you want there...

By the way, just fork out the extra few bucks and get both... save yourself the trouble... But damn, you really got me thinking on this one. I've never heard of someone even wanting to do this.

Hey thanks Tuan I will take a look at those articles.

probinu · 06-04-2002, 09:59 AM

Tuan is the SHIZNITTY...he is the all-mighty moderator!! Listen to him cause he knows most everything

I just got off the phone talking to Andrew at Skunk2.

the stage 2's really do benefit from CR increases...for the average enthusiast he recommends 11-11.5:1 CR with those cams to see their true potential at full song. The higher the better. Your limitation will be clearances and pump gasability. The redline really does not need to be pushed past 8500 rpm in most street engines with those cams. Valvespring upgrading despite the stock ITR redline is a must due to lift of these cams and coil bind risk with inferior or stock springs.

Jeff at Importbuilders dyno'd these cams head to head against a set of Jun 3's on the same engine with a popped up CR and they were identical.

As I said, cam spec dictates compression needs. The b16a guys don't need a lot of compression with their rod ratio and smaller port volumes when they get a cam like this. Roger Foo's old b16a made over 200 whp on a stock block. Us tegs however, do need help with compression on the top end and larger port volumes. These cams are upper rpm powerband cams...given the higher lift and duration.

They are not CARB legal...if that makes a difference whereas the stage 1's are and can use stock valvesprings with an 8100 redline.

hey Tuan.

I would like to know your opinion. What do you think would be the best way to go about upping the compression if I were to go with the Skunk2 stage 2 or Jun3 cams since they are pretty much identical. Assuming I'm doing a complete valvetrain upgrade as well.

If I'm going to all this trouble I might as well up the compression a bit to get the most out of the cams.

Also will 11:5:1 run with 91 octane gas? or will I have to use octane boost every time I fill up?

The best way to increase compression is using higher compression pistons. A cheaper way is to mill the head. I believe you can get 11.5:1 with a milled head and thinner headgasket. JDM ITR pistons sounds like something you should look into.

So say I had the head milled and installed a thinner head ghasket to get the 11:5:1 compression. would this hurt my stock pistons at all? Cause I dont want to have to go in and change them out because I cracked them or something broke because I was cheap.

V8KILLR · 06-05-2002, 02:25 PM

I have the CTR pistons and a Stock head gasket on my 00' ITR and I have no problem running pump gas. I dont know the max Octane they offer where you live, but in SC the max is 93 octane right now.I think my compression is around 12.2-to-12.5 tunning is the key. Just my 2 cents.......................................

Fooser · 06-05-2002, 02:27 PM

ya here in CA there only 91 octane. if I were to go extreme I would have to use octane boost or actually purchase gas from this local race shop. Maybe I will just buy stock in octane boost and put a bottle in every time I get gas.

would probably leave me at around 103 all the time. That has to be bad for something.
