This as probably been asked about a 100 times but I don't know what to type in the search to see. So my ? is I know it can be done but is there any benefit? I can get some really cheep.

 

yes I would go for a set of 94+ gsr cams they are slightly better than 92-93 gsr cams and usually have less mileage. I would only buy gsr cams if you were gettin them for 50 or less or if you just dont have any cams at all to use. The benefits are so small thats it is hardly noticeable. Your looking at maybe a 2 hp gain at the most. Save up and get some itr or ctr cams....

 

First gen b16 cams are the worst dohc vtec cams out. GSR cams are a cheap upgrade and really work well with boost.

 

There's a pretty good gain when you're boosted,,but N/A it's not very noticeable..
The guy from evans tuning did a b16a vs. gsr cams dyno test..

B16 cams are dotted lines,gsr cams are the solid lines, in an stock block lsvtec with a gt30r turbo..

 

ok, it don't even seem worth the work to put them on. Thanks for all the help.

 

your kinding me my buddy measured the lobes on his b17 gsr cams and set of b18c1 cams and there the same

 

ok. so you would rather have a set of 92 gsr cams than 00-01 gsr cams? go for it. I always understood that there was a slight difference between the two. Just because your "friend" measured his dont mean squat. I was simply saying that the new ones or most likely gonna have less mileage.

Are you sure about that?..I mean the b17a cams are in a b16 pr3 head..And the b18c1 cams are in a p72 head..So I would think they'd be different..I always though the b17a cams = 92-95 b16a cams..Or maybe the 94-95 gsr cams = 92-93 b17a/92-95 b16a cams,,and its the 96+ gsr cams that are different,???

 

we checked they are the same

 

I put a set of 98 GSR cams in my first Gen B16, replacing the auto B16 cams that came with my longblock. With tuning on the dyno using only a FPR went from 124 to 147whp. The GSR cams are worth it if you get them cheap. The 2nd gen B16 cams are a nice upgrade as well. The 1st gen B16 cams are the worse. I have a set of 2nd gen B16cams just sitting, if you are interested PM me.

BTW, after the GSR cams I then installed the CTR intake cam with the GSR exhaust cam, car is now making 158whp

 

whatever u guys say
b17a, b18c1 cams are all the same i would assume b16 cams are the same aswell

The 89-91 B16A cam lobe profiles are the weakest of the bunch. All of them are weaker - whether you have a 1-series or 5-series 89-91 B16A engine. If you can get a set of newer cams, I highly advise it. (NOT EVEN TO MENTION THE SORRY *** AUTO CAMS)
• A majority of the 92+ B16A/B17A and 94+ B18C (JDM +US) cam profiles are pretty much the same. Although, the 94+ B18C cams seem to put out a bit more power....just a little bit. Dyno-testing is the best way to tell between these stock cams. Again, 'R' cams are best to have over these....
• Your best bet over any of the stock cams is to purchase a set of 'R' cams. Those blow away any of the stock cams - about 7hp on an naturally aspirated VTEC engine. Of course, if you want more cam power, try Spoon or Toda. Just make sure you get the proper valvetrain to work with those bigger cams or else you can end up with damaged valvetrain components!

• One thing I'd like to mention is that, JDM aftermarket VTEC cams were mainly designed for circuit racing (roadracing in laymen terms). I always here people complaining about the high prices of JDM cams and engine parts. People need to understand that these are high quality parts and a lot of R&D is involved. The Japanese are all up on the road course racing tip and not too much into drag. Although, there are a few Japanese drag race companies, but I'm compelled to talk about that. My point is that, when people dyno their cars with these JDM aftermarket cams, such as Toda or Spoon, and they don't see the top-end power that they were anticipating to see, they should know why. Most of these cams are designed for mid-range power, which is needed on the circuit. So, not all JDM aftermarket cams are the right ones for your type of racing.

^That is a quote from FFSquad (except for the Bold, which was added from my own dyno experience)

 

hey see I was right they are the same but I wasn't sure about the first gen b16 cams

 

mine is a 2end gen B16a from a del sol. So if I can get my hands on some 94 and up gsr cams I could bake a little more power. This motor will be turboed later. I may just get some skunks.
