JDM B16 Cams

[duckey]

hey guys,

in regards to the AUDM B16A2 cams and JDM B16 cams...are they the same? is there a point is replacing them?

regards,

duck

IMO no point going from 16 to 16, better off going B18 Typer R or aftermarket.

[NightKids]

Are Type R cams an upgrade for B18C2?

Are Type R cams an upgrade for B18C2?

Yes, they are.

But my understanding is that if your putting in more aggressive cams into a C2, it's best to raise compression too?

Duckey:

B16A2

Int-230 dur. / 10.6mm lift
Exh-227 dur. / 9.4mm lift

JDM B16A

Int. 240 dur. / 10.7mm lift
Exh-227 dur. / 9.4mm lift

Very, very, very marginal difference. Short answer, no, you will probably not see any benefit from changing over to these cams. However, if you were to change to JDM B16B 98 spec R, then there is a noticeable difference.

Genunine question or sarcasm..?

[NightKids]

Genuine. I've only been reading on aftermarket cams

[dougie_504]

Yes ITR ones are an upgrade for C2. My friend is running full ITR head internals in his C2, pulls much better. They're a good OEM upgrade for the lesser B-series if you don't want to splash out double the money or more for aftermarket parts.

For B16A I would only bother using ITR internals or aftermarket. I use the Skunk2 stage one, great for daily/street because it's not too rough etc.

Yeah the guys are right. Also apparently ctr ek9 cams are similar to itr cams? I think the ctr cams are more aggressive from memory correct me if I am wrong.

But I know for sure the 00+ itr cams are more aggressive than the previous models. U can tell which is more aggressive cause one has an extra ring on the cams and the other one doesn't.

If your gonna upgrade b16 cams fo for ctr ek9 or it's cams to notice a difference and may swell get valve springs and retainers done too while ur there

[kriZy]

Bah let me correct myself iPhone fail. I can't edit cause im on taptalk. Upgrade to ctr ek9 cams or itr cams to feel a difference.

Has he done any bottom end work at all? I'm interested in doing something like this.

Correct. I do believe that EK9 Type R cams are the most aggressive OEM B-Series cam Honda brought out.

No, just head for this engine (N/A engine) - enlarged ports, 3-angle grind, re-welded combustion chambers, full ITR internals and IM/TB, matched manifolds. But he also has another B18C with full head & forged block build which he's about to run in for his turbo setup :)

The CTR pistons can also be used in the B16A for higher compression :)

I've recently had installed CTR cams and there is an increase of about 8whp. Vtec comes in harder and I've hit the rev limiter a few times. This didn't happen before because the car stopped making power up top. If my OEM rev limiter is increased, the car would continue to make power over the last few 100 rpms.

Good mod. And yes the CTR valves and retainers should be used.

[NightKids]

Can the EK9 cams be used in the B18C2?

[kriZy]

Can the EK9 cams be used in the B18C2?

I would never guess for anyone to ask this question. Interesting. I reckon it can. Dont see why not cause if the itr cams can fit in b18 and b16 then the ek9 ones can too. It's all b series were talking about here

[NightKids]

They're really expensive aren't they the CTR cams? There's none on eBay right now....

[dougie_504]

Yes they're all interchangeable in B-series VTEC. CTR's are rarer than ITR's and even ITR's aren't 'easy' to find.

[Frosty-Civic]

how much are ITR cams

[kriZy]

$400 mark.

[dougie_504]

yeah about that or 500+ for full cams + valvetrain

[Riced_Civic]

OP, think about it this way.
if u do find it, will the amount u pay for the cams and install do u reckon its worth the price for the small amount of gain.

[dougie_504]

Yeah if you're paying labour for somebody to build your head (and porting, 3-angle grind etc) may as well just spend a bit more and get some stage one cams with adjustable gears...

[Vvvtec]

Agreed with Dougie on this.

BuddyClub Spec 3 (entry level BC cams, don't be fooled by the name) are around $550 from the US now.

[Vvvtec]

Alright, they are a little dearer since I last checked, but for about $600 you can get these/or the BuddyClub equivalent.

Factor in say another $500 for Adjustable Cam gears, springs/retainers etc and you'll has a very nice street setup. I will most likely go down this route eventually.

They also market them as being straight drop-in which is also good. However if your going to go this far it would be silly not to get a tune aswell.

Anyway, I'm getting offtopic haha.
