I was wondering if i could get some ctr or itr cams and use them on a stock tune and use dual springs and retainers as well.

ide say no...

Technically you can. But would I recommend it, no. Im a firm believer in any modifications beyond the usual I/H/E require a tune.

I've installed several sets of R cams on stock motors and they ran very well.

I have to disagree with the first post. I'm personally running a just a CTR intake cam (just purchased the exhaust cam) with my stock valvetrain and basic bolt-ons for going on 2 years. With a unchipped pw0, I was able to achieve 156hp and 109lbs-tq. So if you keep your stock redline you should be fine. Also note that you will get more gains with dyno tuning your setup.

true... i was under the impression it would work fine but not run as well...

it depends what bolt ons you have. if you have i/h/e with a fuel regulator you can turn the fuel up a little bit and maybe advance the timing some.(every car is different so this may not be good for yours). i been running gsr with itr cams without a tune for about a year w/ p28chipped and never encountered a problem. Took my rpms way past 8k to but im not saying that is safe

it should work. you might have to play around with the cam gears to get it to idle right and make the most power through. since people have already done this i would put more weight on their comments than i would others.

I'm not sure why you would "have to play with cam gears for correct idle" as they are an oem camshaft? All the sets I installed used the factory "gear," idled like a stock motor.

I ran ctr cams with my old b17 untuned.. the car idled and ran well for two years before I got it tuned.

racebum

depends on his deck height. if everything is stock that's true. slap together motors with possibly shaved heads are another story. if he'd doing a build one would hope that the surfaces have been trued up.

so, should i get ctr cams or itr cams?? also i already have supertech dual springs and ti. retainers.

ITR and CTR same exhaust cam.
On the older series ITR cams the intake had 3 degrees less duration.

ITR 96-99

Int-240 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift

CTR and ITR 00-01

Int-243 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift

Yes you can, it may not be "in sync" like your b16 cams but it wont damage anything, idle will be fine.

if its power your looking for, dont expect much more until you tune.

CTR cams are more aggressive than the old itr cams. The ITR 00 and newer are the same as ctrs. I have used them on stock valvtrain many times and have had no problems with them. You will have an increase of power and will feel it. But if you want to get the most out of them you need to tune them.

Gosh. Reading this post made me realize how many clowns post misleading information. Raising fuel pressure and playing with the cam gears. Don't listen to these people. They no nothing. They pay people to do their work because their lack of knowledge and skill.

I actually have ctr cams in my jdm b16 now for like a month with a stock ecu and it just ain't runnin right all the time. It tends to bog alittle at like 50 MPH and it smells like its runin rich. I even got a new o2 sensor and it ran fine for like 2 days and then it started doin the same thing. I guess my last alternative to get to the bottom of this is to get it tuned. I advanced the timming today to the mark in front the middle mark towards the front of the car and i guess it made alittle bit of difference by idling a bit smoother but i'm not 100% happy on how its runnin right now.

Sounds like ur timing is off they should drop right in basically

PP the head... Thoughs cams need a little better flow to get the most potential out of them assuming u haven't done this yet

tuck1crx

speed density systems require remaping to run at there full potential. if u dont its at your own risk

the cams wont make more then a 5-6whp difference...not enough to even notice. Ive seen it on many a stock motor with r cams swapped in on the dyno its not a magic power maker.
the stock ecu runs a little rich anyway so the cams wont hurt anything.

It will be an improvement.

I ran fine with Blox As on a stock map for quite a long time before I was able to tune. I kept out of VTEC for the most part, but around town and on the primaries those cams might as well be stock. I'm guessing you've got another problem. Have you checked your engine timing?

crxsi1

5-6 is a little low maybe ur thinkin of the older r cams but there not that much different... I've seen 15whp gains, that is if we r talking about a b16 head... Basically turning it into a type r head or even swapping one on... I'm not including any other parts! The b16a loves thoughs cams with its great r/s ratio it really utilizes the potential... The type r head can handle 9500k very well as well as the b16a well actually it handles it pretty much better then any other motor so imo that combo is great and u will have tuns of fun...

I suppose if you swap in those cams and install some crack in the ecu, those numbers and claims would be realistic...
