What kind of a difference have you noticed, and would you recommend it to another B16 rex owner? I've been toying with that idea for quite some time. Also, if you did the installation yourself, how complicated was it? I know you can hear a significant difference audibly, it sounds more throaty and aggressive, but I want to know about satisfaction, and ease of self installation. Any feedback would be appreciated, guys.

 

i'm not familiar with the CTR cams but when i put my GSR cams in my B16A, i found the install to be quite simple. probably the most tedious part was re-adjusting the valve clearance. just make sure you torque everything properly.

I've got the CTR Intake cam. It wasn't that hard to do, and it's about the same as a GSR swap, but since it's really designed for a B16 block, it's a little better. You'll need the new valve springs, and these are almost the same as the exhaust springs already on your ride... they work, but nobody's sure how long. As for power, you'll obviously find more. Also, make CERTAIN that it's got the double ring stamp on the end of the cam. I'd reccomend it though. Also, try to get some GOOD cam seals while you're at it. I'm not good at explaining this ****, so hopefully someone with more experience can help out.

 

CTR valve springs you mean?

 

big difference hear . if you already hace other bolt-ons you`ll notice a big change . just tune it and go

Yeah... I'd recomend it. I know Crane and Jun Skunk2 etc. Make awesome springs. I was told to swap them, but I have no clue if you need to. I hope someone else can help...

if you are getting cams..and want to get full potential.. upgrade valvetrain too and buy both cams.

buy the valvesprings and have a shop install them while they do a valve job.

The cam and valvespring install was very easy, but i would recommend a valve job. just to be safe.

 

would you recommend the CTR cams or the ITR cams? I have a guy that is lookin to sell his ITR cams and i'm wondering which ones work better. From what I keep hearing, the B16 responds better to the CTR cams. Any feedback? Also, referring to when you say to buy the valve springs, are you saying buy CTR valvesprings, or buy B16a valve springs?
Sorry about the multiple questions, but i'm about ready to pull my hair out with this motor as far as wanting to do upgrades to it that will compliment the motor to the best of its ability. I don't want to do anything without talking to guys who have done what i'm wanting to do. I've also heard people say that the CTR intake cam and ITR exhaust cam is the best combo that they know of. So many differing opinions... anybody have a definitive answer?

 

Well, the ctr, and itr exhaust cams are the same. The ctr intake cam is better than the itr, so just make sure you get the ctr intake cam, for best results. Ryan

 

Shopping list...

CTR Intake cam.

New BETTER valve springs than what's on the B16A. I'd reccomend the
CTR springs... as they're cheaper than some aftermarket companies. However, any better/stronger spring will work... such as Crane, Crower, etc.

Get a valve job.

New seals.

And yes, you've got it right, the CTR intake is the best.. you can expect a (conservative) 15 hp gain right there. You're good to go as far as I can tell.

 

I appreciate your replies. Quick question; will getting the CTR springs change my redline in any way, shape or form? I'm guessing no unless i change all the internals to CTR internals, but I figured i would ask anyway.

The CTR springs will change your redline because you will be able to rev at a much higer RPM. The stock valve springs on a b16a are not designed to rev past 8K, the CTR srpings will allow higher RPM. The redline on a b16a is directly related to the cylinder head, springs, retainer's etc. The bottom end will rev as high as the springs, retainers and cams will let it.

</TD></TR></TABLE>So basically I would need to get CTR valve springs AND retainers, as well as the CTR intake and exhaust cams to have the same redline as the CTR, correct? And if so, when i get a valve adjustment done, is there any difference when you use the feeler gauges seeing as how I will be using CTR valve springs instead of the stock B16a ones?

 

How to install them

You don't really need to adjust the valves, just make sure yours are in spec.

 

great, now i have someone telling me that a CTR intake cam and a 00-01 ITR intake cam are the exact same thing. Can anybody confirm this please? I'm thoroughly confused now...

they are the exact same, however you wont find alot of 00-01 itr cams, there are alot more of the 97-99 out there.

as far as the springs,
the b16a has the same springs on the intake side as the ctr so technically you only need 8 valve springs from a ctr, as far as retainers i wouldnt trust the ctr/itr retainers, i would get something aftermarket like portflow titanium retainers.

if this was me though i wouldnt do half the stuff mentioned above, there is no reason to rev to 9k unless you are making power to 9k and ctr and itr cams arent going to give you that power up to 9k,

look at my chart, see where i stop making power. there would be no point in spending all the money on springs and retainers, and a new ecu to rev to 9k when u stop making power at 8k

I'm not concerned with revving higher than 8000-8200 if theres no power past 8000.
Ok, so the 00-01 ITR intake and exhaust cams are exactly the same as the CTR intake/exhaust cams. Now there's a guy offering his pair of CTR cams to me for 400. Sound good?

Check that out, great specs on cams.

If you notice the ITR and CTR cams are not exactly the same.

 

so is it a requirement to use different valvesprings when using CTR cams, or can the stock b16a valvesprings be used safely? thats what I really need to know at this point.

 

yes you should get ctr springs

Actually the 00-01 itr intake cams has the same lift as the 98+ ctr intake cam.

 

if you're going to keep the stock redline/rev limiter and you're only changing the intake cam you can get away with not changing valvesprings

if you're going ctr/itr cams for intake & exhaust you can move your b16a intake (dual) valvesprings to the exhaust side and then buy a set of 8 itr inner & outer springs for the intake side.
