vtec dub

Hey 1 2 NV.

duration lift duration lift duration lift
Type3 INT 60 (240) 6.5 76 (304) 12.0 63 (252) 9.0 0.17 1004M-H003
EXH 63 (252) 8.7 76 (304) 11.5 60 (240) 6.2 0.19 1004M-H103

If this is my spec on JUNspec3. At what crank degree should I then have max lift on my cams?? As this only tells me the duration and the lift.
Plse help

i wish i could remember. i had those exact cams but forgot the crank degrees they want them dialed in at.

a quick search with a post asked by me 3 yrs ago revealed that the cam centerline is 110IN 110EX according to the guy that answered my question.

bringing back a old post!

I'll bump it again. Reason is cause you can't always go by the cam card. Just last week I was degreeing a customers car using S2 Pro 1's and the opening and closing specs were way off. Called them up and spoke to one of the tech's and he told me to try a different set of spec's on both cams. Come to find that they were closer than the card but still not perfectly on. I don't have the numbers here in front of me but they were off by at most 7 degrees on the wheel in one case.

Also very important. I dont think it's mentioned here and not in S2's "how to". Be sure to keep in mind that opening and closing specs will be at .050" lift.

Great thread BTW

Where did you guys purchase your cam fixtures/degree wheels ?

Thanks for this write up, I am looking forward to using it to degree in my pro1s in the future.

Not necessary but the correct way to install IMO.

this is a great write up but im still having trouble figuring this out....

heres my cam specs for my skunk2 pro 2's


now which numbers do i actually need?
primary?secondary? and do i use the spec for the lift at .050''
thanks in advance for anyone that think they can help me out!

ef92b

use the VTEC lift and duration figures and @0.05"

rh76pogi

Those numbers won’t help you. Call skunk2, ask for the Peak Lift specs or the opening and closing specs @ .050” lift. That is what you need…

Noob question for you guys: If you take a look at the link i've attached, can i degree my cams in using the values for the primary/secondary lobes? or would it still be better to use the VTEC-only lobe values?

insidiouseg-6

I just read both pages of this thread and i have a few noob questions (bare with me)

First question, i do not know what the abreviations stand for

Intake Cam:
BTDC
ATDC
ABDC

Exhaust Cam:
BBDC
BTDC
ATDC

Pretty much i just don't know what the A and B's stand for. I figure TDC is top dead center and BDC is bottom dead center, correct?

2nd question, if you check the v2v and p2v clearances (i read the entire other thread covering both subjects) is it even necessary to clay your motor? It is my understanding you clay a motor to check those clearances but if they are already found whats the point? If i am wrong please correct me.

Please don't flame, still a noob when i comes to checking clearances. In the upcoming months i will be building my first motor and i want to make sure that i do everything correctly so that it runs properly

Before Top Dead Center
After Top Dead Center

vtv to is valve to valve, i dont know where you got ptp. You check ptV (piston to valve) by claying.

God, i really need to start re-reading what i type. I meant to put p2v not p2p *facepalm*

This link https://honda-tech.com/forums/all-motor-naturally-aspirated-44/how-v2v-p2v-1891614/

12nv doesn't clay to check the p2v. If i were to do the same i would be able to avoid claying?
