Well, I have some $ saved up so I decided to purchase some CAMS!

Now, I have some locals selling JDM ITR cams and this other guy selling CTR cams.

Which would be the best for the bone stock B16A?

Would I also have to upgrade my vavletrain too? If so, what parts of my valvetrain do I have to upgrade?

I am going to verify the cams by this pic so that I don't get scammed.

But the 00 US ITR and CTR cams look almost identical.

Please help me!

 

00-01 ITR cams will give you the same output as the CTR cams.

Depends how much you want to spend and how much power you want to make.

For more power and tuning involved, I highly recommend the skunk2 stg1 cams, toda a, and spoon cams.

For mild oem reliability and tune, stick with ITR/CTR cams.

 

you dont want to buy cams, you want to buy my gauge cluster

 

Would the stock B16A valvetrain be sufficient for the more aggressive ITR or CTR cams?

no, you need the double springs on the intake side

 

this is true

u would need to get at least that much if not the whole valve train done

like dual springs and tit retainers

OEM B-series VTEC retainers are good till 10k rpm

 

All B16's come stock with dual valve springs on the intake side. You will be fine with running all types of OEM cams with your stock B16 vavletrain. You only need to upgrade when you go aftermarket.

not true, automatic B16a's only have single valve springs on the intake side, regardless the b16a valve springs are not stiff enough for a higher lift cam

 

stock springs are fine until 8200+. My old crx had ctr cams and stock valve springs all day.

As for the itr/ctr difference, the exhaust cams are identical, the ctr has 3degrees of duration at tdc more teh the itr. So technically you could get some cam gears and advance the intake cam 3 degrees, and you will have the equivelent of a ctr intake cam. I hope that all makes sense.

I've been running ctr cams on all stock b16a vavletrain for about 2 years with no problems, You only need the valve springs and retainers if your going to rev more than 8200k, wich is stupid since you wont make any power after 8500rpm.

The exhaust cams are identical, the ctr intake cam has 3 degrees more duration than all itr cams before 2000, if you get 2000-2001 then the cams are identical.

Instead of getting valve train you should get a aftermarket header with at least a 2.5 inch collector and then a 2.5 inch exhaust, if you dont upgrade your exhaust you wont be able to take advantage of the cams.

i made 156 whp with 2.5 header, exhuast, and itr cams, untuned.

Cool, thanks for the input people!

I think I'll go for the ctr cams... but how can I check for overly worn out cam lobes?
If I can get ITR valvesprings and retainers... it shouldn't hurt this mod right?

Also, about the exhaust... I have a stock B16 header with highflow cat and full 2.25 piping to the exhaust. Is that sufficient enough for these cams? I'm not going to track this car everyday... it's just a daily driver.. so I don't want a loud loud car... its already loud enough with the polyurethane engine mounts.


A little off topic but for those of you that have this motor (B16A) with the S1 tranny, what speed do you cruise at maximum on the highway? I was driving back and forth from kingston to toronto this summer like 6 times, and I was travelling at 140-150 km/h for the 250km drive.
I checked my oil the next morning and half of it was gone.
I guess being in vtec for 2 hours is not good for the motor... I think I need a better tranny.. something that is not in vtec at 130km/h. Maybe the YS1? I have no clue.
btw I calculate when vtec hits by km/h because i dont have a tach in my STD hatch

 

you would only be in vtec for 2 hours if you were at wot (wide open throttle)
at cruising speeds you are not in vtec.

Springs and retainers will not hurt anything, but its very costly to install, and quite a bit of a pain in the ***, wich kind of effects the gain per dollar spent on this mod.

Your not going to see a big gain with cams if your using the stock header, if i were you i wouldnt waste my time.

swap out your 5th gear for an LS 5th gear

 

CTR cams... Thats what I went with... I would change the valve springs too (ITR)... Just my recommendation... Also, I would change the lost motion assembly tooo... Good luck and enjoy them... I have fun with my car... Need to get it dyno'd and then tuned....hahahahha

 

What do stock B16 cams look like compared to those?

I've fully elightend myself with oem cams information with this special link
http://www.ff-squad.com/tech/temp/VtecCams.htm


But I am totally pissed off that the guy already sold his ctr cams to someone else!!! Don't you HATE when that happens?! FACK. I'll be on my way to finding another pair...

 

Good lookin out bro.

 

Ok lets set the record straight here.

1. 98+ ITR (USDM or JDM) cams are the exact same cams as the CTR

2. The difference between the 96-97 ITR cams and the 98+ is the intake cam, it has 3 degrees less <U>duration</U> (which can not be made up by any advance or retard of the cam), but the exhaust cams are the exact same.

3. Stock valve springs will be fine up to about 8400, and if you want to go higher get the ITR intake springs and move the stock intake springs to the exhaust side, then you're good till about 8700.

4. Titanium retainers are a waste of money unless you miss a shift or over rev the **** outta your engine, so you decide if you need the added insurance.

5. IMHO... You can find better cams for the money than Skunk2, their stage 1's are about equal to ITR/CTR and from what I've heard from VERY reliable sources, their stage 3's break valves, etc. Take a look at jun, toda, omnipower, or rocket, all produce great cams.
