Is there anyway to visually tell apart gsr vs b16 cams?

 

USDM B16 and GSR are the same, no need

 

Wrong. Looking for pic. BRB.

Dammit...site's down. Email Katman and ask him for a picture of the two.

 

b18c cams are larger than b16a 5 speed
b16a 5 speed cams are bigger than b16a automatic cams

 

JDM B16 2-3 gen is a 240 45/15 intake cam LiKe TypeR y0 according to Gspeed/powered by honda page (old school) the first gen is a 230 40/10 cam, same as the 92-93, 94-02 GSR intake cam so I would assume the USDM spec is also the same for USDM B16a2, considering most guys purchase a ITR/CTR intake cam to mimick the 2-3gen JDM B16a:

< backing up my previous comment

the kid with the GsR y0

question... why do you need to know the difference for very little if any difference between the cam aforementioned... curiousity? IF you intend to use one or the other, get an ITR or CTR and you'll see a difference for sure...

the reason why I ask is cause I let my "friend" borrow my GS-R cams for his b16 when I got my crower cams and I am getting them back now and I wanted to make sure that they were my cams not his b16 cams 'cause I am pretty sure that they are differnt at least from the older b16 cams. thanks for the help, although if anyone has pictures comparing the two that would help as well (I emailed katman, hasnt responded)

 

Sorry everybody but I just thought about this... to MikeSarr_GSR man you gotta get your old avatar back... that VTEC valvecover was bad ***.. Too bad we all lost our **** when H-T was doing whatever they were doing... Oh well... Peace

 

They are identical. Ive seen numerous charts showing the b16 and b18c cam specs being the same.

 

Seems like there is a little debate here.... So you're sayin that 1st Gen B16A cams are the same as 2000 B18C1 cams???

 

yeah, http://g-speed.com/pbh/b16a/

 

That chart may SAY they're the same, but guys have dyno proven that they're NOT. I have 1st gen b16's in my car now and have some later model GSR's going in soon, I'm going measure the lobes and see for myself if there's a difference.

 

This is exactly what i've seen... I really don't think that the cams are the same but several charts that I have seen state that they are... I had some old specs awhile back and they were different... I mean especially 1st Gen B16A, those were like the first VTEC cams ever made and revisions have been done over time... I guess it's just gonna come down to mic'in them... I can measure the lift but I have no dial to measure duration... Oh well, sometime when I get really bored i'll see what i can do... Peace

 

yes there is a way.
You can peep my B-series DOHC VTEC cam ID page here:

although it's due for an update.

 

Same cams, different motor, the b16 and b18c do not have the same rocker arm ratio! That means the same cam will have different lift at valve depending on which rocker arm is used.

 

So people that are swapping their B16 cams out for GSR's and NOT changing the Rocker arms really AREN'T getting gains?
I'm not arguing, but I've heard/seen people gain power by swapping between these 2 cams I will get the R/A ratio's for both today and post em.

 

holy jees man, the spec is the same. anyone can dyno prove something... if we are talking 2-3whp c'mon. the 2-3gen JDM B16 has a intake cam with the same valve closing/opening specs as ITR. that and .2 cr was good for 10 more hp in stock trim. look at the spec. why not just get an intake cam from an ITR or CTR and really gain something solid? I dont understand what you think you will gain by researching these cams further outside of the knowledge you would gain from mic-ing every lobe honda ever made...

 

Ya, no need to argue. Im pretty sure they are the same cams. Also, GSR cams would be in demand for B16 owners if they were different. Try selling some GSR cams. You'll sit on them. But back to the original topic of you telling them apart visually, I dont see how you could unless they have different numbers/letters marked on them. The ITR 00+ ITR cams are a great upgrade for the b16 or GSR. I got about a 10 hp gain.

I don't get where you're getting at with this statement, are you saying 2nd/3rd gen B16 intake is the same as ITR or not? My point is, the cams ARE NOT the same, B16(any gen)/GSR.
People are swapping out B16 cams and making more horsepower with the GSR's- this is based on FI setups, btw. Go to the FI board and you'll see proof. If it were only going to net 2-3hp, I wouldn't bother. Also, the rocker arms ARE the same for GSR's, and the B16(2000 civic to be exact) so any gain realized has to be because of the cam.

 

B16 cams are made for a 1.6L motor and the GSR cams are made for a 1.8L. Obviously they did not use the same cam for these motors which are different . Read katmans page once again. B16a cams are the weakest period. Note B18c is not in that statement.

 

if you can, try and see if you can look at both sets up close, check the vtec(middle) lobes, if a certain set seems taller or looks like it has more duration, thats your set.

 

I've measured both cams and they are NOT the same. Even by looking at the specs in the service manuals, the have different lobe heights. The exhaust are very similar, but the intake cams for the GSR have more duration and .2mm more lift.

 

No they are NOT the same.That one guy is smoking crack.Gettin all mad and meanwhile he's wrong.Wonder how that feels. . . . .

there are different markings, but the specs posted here
are simliar if not the same. as far as my statement of the
2-3gen B16a being different, check the Intake profiles. they in turn
make 170 at the crank compared to the 160 of the B16a G1.
Duration spec is larger, LIFT is almost (10.6/10.7) the same.
My only point is that the cams between USDM B16, JDM B16a G1,
and B17/18C is negligable if any. If anyone is making power with
any combinbation of stock cams it doesnt suprise me, cams can
wear

 

I'm not researching them for gains in my car, but I let my friend borrow my GSR cams for his crx and he has now sold the b16 that was in the crx and I want to make sure that he took out my cams and put his back in when he sold the motor. I Just want to make sure that there is no difference between the two so that I don't get the b16 cams back vs my og cams.
