Ok I'm planning on swaping out my itr cams for some buddy clubs spec III. I've been doing research and I'm still uncertain on how to properly match a cam for target hp. My goal is to get around 200 to 210 whp.

My question is will these cams be a good sutible option.

Will the stock valve spring and retainers be good with these cams.

Anybody using these where is you're vtec engaugment points set to. I know with the spec IV people have to set them higher.

Any info or if you can point me in the right direction would help tramendously

 

Sry more info is I will be upgrading to 310cc injectors to acomidate for the high duty cycle stress that will be put on the stock injectors along with fpr. I intend to use the oe fuel. Other things are the cyl head is stock I will be port matching the heads intake and exhaust ports. Along with cleaning up the head.

 

The Buddy Club IIIs need at least 11.0-11.5:1 compression, with uprated valvetrain above the ITR OEM valvetrain, and you need some tuning management to be able to get the best out of those cams, and not just something that changes VTEC points or a V-AFC Neo or whatever. You can keep stock FPR if you use 310cc, but to get best results, 440cc with good management is BEST

 

Up for more info, because I'm about to do the same.

 

Buddyclub specs out 10.0:1 to 13.0:1 on the site, of course 11.0 is probably beneficial it's not required. It's not necessary to upgrade the valvetrain either, if using dual valvesprings, although it's always a safebet to do so.

 

I've read on some other forums, and dead threads from 04 that the itr springs are sufficiant. Any recomendations on springs.

 

There has been some back to back testing of the BCIII on an ITR engine and there were minimal gains.

If you search the forum you will find the results I believe the user was was RedSTD or something like that

 

oh damn
i just bought a set for my b18c5 too

 

Ive heard the same thing about not needed to upgrade when switching to BC3s, anyone have any actual experience?

 

A long time ago on Buddy Club's web site, it said say use "ITR valve train". It no longer says that, why not sure?
But I have read up on guys trying to run BC SPEC 3's on GSR valve trains droping valves. Wonder why.
Maybe because the ITR springs are stronger and the ITR valve is lighter. If Buddy Club actually ran these cams in there race cars with OEM parts they where ITR and CTR parts NOT GSR parts.
I honestly think it was a marketing trick. Someone said sure it will work with GSR springs and sales increased. Do you think Buddy Club USA paid to repair anyones head or engine that was damaged?
Just something to think about.

 

i run bcIII cams on my 2.0 build. supertec springs and retainers 12.3:1 compression. made 236 and 160ft lbs. bought some pro2 cams so swapping them. my buddy clubs only have 60 miles if any of you are looking to buy a set

 

Weren't there Spec III that were ok to use ITR valvetrain, and then there were the Spec III+ that came out a little after? I think the III+ required better than ITR valvetrain.

 

i thought they were the same cam.. then again maybe they found a way to improve the bc3. mine are the bcIII+

 

I dont know about the USDM ITR motor, but in my nephews JDm ITR motor, it made 193whp. Mods were intake, edelbrock headers, fujistubo exhaust, and only a mild tune! DEF more to give, but without full tuning, cant expect much.

 

my friend is running the same cams but on a gsr head with itr valve springs.. 4k and counting. there not a high lift cam. long duration therefore they dont need as high a spring rate like skunk2 cams. unless your taking it past 9k rmps then youd prolly need new springs on stock cams anyhow. just my .02

 

Buddy Club III+ need the uprated valvetrain. Possibly not so with the III. But why skimp out? Its your motor for heaven sakes. And yes, I've used both sets, and I would uprate the valvetrain.

 

oh yea i did email buddy club usa about this few weeks ago
hello,
I have a honda civic with a b18c5 in it, i was wondering with the
buddy club spec3+ cams can i just run stock integra typeR valve springs
and retainers? or do i need to get the buddy club valve springs and
retainers too?

thank you

Hello James,

It's highly recommended, but not necessary.

Cool thanks for the info. Its still hard to decide, what cam to go with. But I've decided I will upgrade head components. The list and price goes up, but engine safety is a big thing to me. Plus I can do complete engine work. Helps keep cost down which is always nice :D

Any recomendations on springs and retainers. I will be reving to prolly 9200-9500

 

supertec or skunk2

 

I would suggest not to play games with BCIII+, you risk very much dropping a valve, simple as that. I have them for 5 years now, and they even managed to break upgraded valve train. To be more specific, they broke two small VS on exhaust side.

Which brings us to the point, BCIII+ are ABSOLUTELY MASSIVE on exh side primary (compared to TypeR), I am not talking VTEC. Their exh side primary is larger than typer cams on VTEC. Think about this for a second, VTEC size lift on IDLE, all the time, and you will realize why GSRs love to drop valves with these, you can bet your money it is EXH valve every single time, being single spring on GSR.

Type R EXH spring combo is the same as GSR intake spring combo and not enough margin for piece of mind, so this is what I would do:

Run TypeR intake spring combo on both EXH and INT side.

In my opinion this is the best choice with low installed seat pressure, enough ability to handle what this cam does and at least I know that OEM springs have QA as part of the process.

Aftermarket, lets just say that I would not run ANY aftermarket spring with these cams for longer than 1 year, maybe 2 if I feel lucky.

Anyway, just my opinion.

Regards,

Nino

 

Interesting. 10 years on one car with uprated valvetrain and 13 years with another. Maybe I'm just not driving hard enough with the circuit events I do. Perhaps its my maintence schedule that's kept my engine alive.

I'm curious as to where you're basing this information from outside of just your personal experience.

 

It is personal experience, and once burned it is all it takes. Something like VS, unfortunately, has a tendency to destroy good deal of things when their failure happens. Either way, just my opinion like I said, mileage will be different for everyone.

Regards,

Nino

 

'hey is this normal for buddyclub spec3+ cams?



i got mine used, and was talking to the buddyclub usa guy Jerry and he said "some imperfections in casting is normal" i thought man they looked chewed up. He said maybe to try to polish it out, but he'd use them.

I'm not sure what's going on. Do any of you other bc spec3+ guys have this on them? this is on my exhaust cam.

 

not on mine. not yet anyways. there smooth as they were new

 

what are the required degrees for these again? i was told -1E +1I
