hey guys.. i hate to do this, but it seems like i cant find a answer to suite what im looking for.

im working on planning out this build.. its going to be an ls vtec, sleeved to 85mm (2.0L basically).. going for a compression of about 11.5-12.5(havent decided exactly, depends on cams) on 93 pump gas, trying to decide on cams.. ive been through the all motor dyno thread numerous times looking at peoples builds, and what cams worked for them and what people are using.. it seems like ALOT of people have skunk2 cams.. as of now i have buddy club spec 3's in my b16, waiting to build my ls block and get it sleeved here soon.. i kind of had my heart set on buddy club spec 4's until i noticed a TON of people running skunk2 cams and making power.. since my motor is going to be a 2 liter with high compression of course im able to run a bigger cam. but how big? and whats reasonable? .. i noticed that the BC4's have basically the same lift as skunk2 stage 2.. i would like to NOT have to rev this thing past 9,000.. my car is NOT a daily driver(but is a street car), however if i choose to take it out for the day or drive it i will... which cam would make the most power out of those.. i was thinking about skunk2 pro series, but i have a stock cast b16 head, does that matter?, and dont plan on porting it any time soon.. just trying to make the most power (would like to get over 200 realistically, dont expect no more then 240 but it would be nice).. would love to get an 11 second pass if that isnt too much to ask for, but i would be happy with 12's, the car is a crx...

if anyone here is running buddy club spec 4's would you mind posting your build? same with the skunk2 pro2

edit:is not a daily driver but is a street car, and want it to stay streetable.. changed to pro2

Jun3/S2S2/M22x/Pro1/Toda B/C would all be good profiles, maybe even a Pro2 or M24x but would probably need to rev past 9 with those camshafts. What intake and header are you using? What are you tuning with?

 

i have a skunk2 pro series manifold, 2.5 inch intake cold air intake going to get a new filter K&N of course, and i have hytech replica headers.. i have KMS valvetrain in it now, seems to work fine with the BC3 cams, dont know if i would trust it with larger cams so after i decide on cams, i guess ill go with there brand of valvetrain, or supertech..

edit to clean rice: ... have you heard any good things about the BC4's?

My advice would be to run S2 VT with S2 cams, Rm VT with RM cams etc.

I don't like BC products but it's just my personal opinion. I will not elaborate as I am not the one who has done the testing, if he wants to chime in then he will.

 

yea im most likely going to match the valvetrain with the cams i choose.. what do people think about pro 2 cams with 12:1 compression, and non ported head? .. im just trying to get the most power from my build (2.0).. mid range an top end

 

I've consistantly seen and tuned 2L B18C/C1/C5 and LSvtecs make 215 to 230 whp depending on the manifold, header, and exhaust with pro2 cams.

 

wow, i like the sound of that.. my goal was 200 with jsut the lsvtec (1.8) then i was ehh i think im going to bore it out an sleeve it an just go all out with 85mm... what kind of manifolds, headers, and exhaust people using making that kind of hp.. as of now i have a skunk2 pro series manifold, hytech replica and a 2 1/4 in exhaust.. i know i should get a bigger exhaust, but when i got it, it was a stock b16 so it was fine, still does the job, as of now its still a b16 with bolt on's and head work.. going to be starting on this 2.0 build soon.. i would like to hit over 200 with the header, manifold and exhaust i have now but i dont know.. i like the performer x manifold, but ive heard theres troubles into a crx with them being sooo long.. but any input about manifolds, headers, exhausts, and camshafts are still welcome, id like to have a thread with some good information.. i should of named the thread something different.. but one more thing.. how much compression is recommended with the pro 2 cams? i was aiming for about 12:1 give or take.. and i cant afford to port my head anytime soon so hopefully i can still reach my goal.. thanks guys

 

S2S3 vs. bc4.

wow that is a big difference in that link you sent me, i heard about that thread but could not find it.. i had faith in buddy club, i have there spec 3's now an was going to go to the spec 4's.. and then i seen alot of people making good power with skunk2 pro series cams.. im soo confused now, i dont know what to do because every build is different and he had itb's etc etc.. ill just have to keep doing my research and looking at how successful other people are.. too bad most people are running the skunk2's an not many with the BC4's.. i would hate to have to buy both of them to see which is better lol i dont have money for that..

 

The manifold and header you have are fine. The 2.25" exhaust is not so good. I recommend 3". As for a cam, BC4 and sk2 Pro2 are both good and will get the job done.

You have to take into consideration all the "parts" that made that setup work. It wasn't just thrown together with random madness.

+1

Consider this..
That test is s2s3's the tuner series vs the bc4's..
The pro2's would slam the bc4's just a fyi..

 

anyone here no of any comparison's of the skunk2 pro2 vs BC4. i keep hearing good about both.. my decision is between the Buddyclub spec 4's and the skunk2 pro2.. ive kind of thought about jun3, havent realy looked too too much into them but i hear a bunch of good things about them as well.. but i would love to see a dyno comparison between the BC4 and skunk2 pro2 if anybody knows where to find one.. or if anyone has went from one to the other would like to share there thoughts

 

im running the buddy club spec 4's and i love them. alot of ppl dont really like them but wen i built my motor i didnt hear much about them so i tried them and they worked out good for me. my tuner was really surprised also he never worked with buddy club cams and he liked them motor was b20vtec 2.0 liter high cr, 12.5. i made 226whp on 93 octane with a ported head though and im swingin up just over 9000 but ide made great high end power. and im on jdm itr header, 2.5 inch exhaust, and a type r manifold w/ stock b16 tb. i would have to reccommend them but if i was to change out my cams to make more power ide prob go with pro 2's

 

oh and as of comparing the bc spec 4's and pro 2's i belive the pro 2's make more power and are better from what i hear but they are for a really aggressive setup. i think the bc cams would do u well.

 

They're both great cams.. I just dont believe that their a aggressive setup cam..
They're not.. now the BC5's or 6's.. ya thats like pro5 terrority..
but the pro2's will do you better **** i'm trying to switch out my s2s2's for pro2's..

 

have you ever tried the bc 4's and how much hp did you make with your headwork

 

i made 212whp 158tq on my b20 vtec setup stock sleeves eagle rods JE 11.5 cpr pistons built head with buddy club spec 4 cams and it made that much power with a stock b16 header and stock intake. with a blox manifold.

 

I guess this whole argument of Cam "X" beating cam "Y" (i.e.Pro2 cams "slamming" BC4s) really depends upon what you're looking for out of the cam. Some people want to get the biggest "power punch" of peak power for their particular style of racing. Not all people want to do that, and would rather (do the smart thing), and tailor the type of cams they want to THEIR needs, and not just to impress others. Perhaps I'm just too old, but choosing cams is like choosing a turbocharger. They attempt to do the same service, just at different levels.

Thanks. BC4's work, regardless of what people that haven't used them want to say

I think you have put that notion to rest, permanently.

 

the reason for the question, sk2 stage2's vs bc4's is because the specs on the bc4's sound great (i know it all sounds good most of the time until dyno) vs the sk2 stage 2 which are really the underdog. well... a friend of mines went to CFT to tune his type R integra (black factory outside still, no ricin). his built is a b20 bottom 11.5 eagle rods stock b16 head, type R manifold, type R cams, ebay headers (ls tranny(he took the type R head off cause he didn't think it mattered...)
So anyways... he dynoed and made 190 hp @130 trq. the guys @ CFT saw the potential in the motor and told him to try th sk2 stage 2's. So...He got them 20 mins later we put them in, went to do a next dyno pull and she dynoed at 220 hp and then 237hp 170 trq.
So.. if you dare to compare bc4's to sk2 stage 2 you can see he made an extra 50hp gain with just a cam change.
I'm really looking for someone to show me much better gains with bc4's and i'll, be impressed!


OH... AND FOR ALL THE SCEPTICS THIS IS NO B/S, I SAW IT WITH MY OWN EYES.

 

i'm sure ur friend made 237 on a dynopack. those figures equate to roughly 196whp. the important factor in determining whether or not cam x is better than cam y....is average power. peak numbers are meaningless
