muffler man

Greetings.
I have read articles about degreeing on the Skunk2 website. But from reading forums I have read something about "locking the VTEC while degreeing" can anyone elaborate on this? Does the camshafts get degree'd in, then lock in the vtec and re-degree? I am planning to get my camshafts degreed in soon and I would like to know if I need to inform the installer/builder any special info. Thanks for everyones time.

Oh and one quick question, is "degreeing" and "dailing" in the same thing? Thanks again.

search for a thread, by the user 1 2 NV. He did a whole write up on cam degreeing..

honestly the best way to degree in a set of cams is on the dyno AFTER you have checked v2v and p2v clearances and created a chart of safe cam gear settings. Play with them on the dyno within this safe zone until it yields the best results.

also, 12nv has a great write up on v2v and p2v

Ok. Thank you. So after I check v2v and p2v, I degree based off of the VTEC lobe? Therefore locking in VTEC then degree off of the spec sheet?
My specs I have are
Intake: 270/12.8 @ 1mm/0.00 lash.
Exhaust: 276/12 @ 1mm/0.00 lash.

V2V will be more of a concern than P2V in most cases, so focus on that.

this also

and yes you base it off the VTEC lobes

thanks for all the feedback everyone. the builder im bringing my motor to mainly builds domestic motors, but he also built my cousins motor (2.0L B18C with toda b's), and to the builder a motor is a motor. I know for a fact he knows how to check P2V and V2V, I just hope he understands what i mean by he needs to "lock" the VTEC when degreeing the cams. wish me luck..

BMo Tuning

You certainly need to stress the fact that vtec must be locked

If he doesnt know how to do this or what it means, find someone else that does.......or at least print him out the 1 2 nv article on p2v and v2v

You could ship your engine to me, I'll build it for you

He probably doesn't. What needs to happen is that the rocker responsible for activating the vtec lobe needs to be "locked" in position as though VTEC were engaged at the time of degreeing. You need to Contact Skunk2Brian for complete specifications as I recently did. It was a WORLD of help

muffler man

anyone have videos or step by step pictures on how they locked the VTEC? I read 1 2 NV's article on the V2V and P2V article, but it lost me at step 4..

There are two ways that I know that you can look the vtec on. One is the belben degree kit comes with some pins that you will need to install on the rocker arm to look the vtec. The second one will be to simulate vtec engagement by injecting pressure air to the head, this is explain on the service manual. We used the second one since the first one requires more work before and after degree in the cams.

muffler man

where would there builder inject pressure to, unbolting the rocker shaft and shooting air into it? and if its in the service manual, what manual is it in? because i believe he uses helm manuals.

The degree kits come with BBs. You take the shafts out of the rocker arm and place the BB in there, replace the pin, reassemble the 3 rocker arm assembly and voila, VTEC is locked.

I wish I knew more about how to lock it w/o disassembling the rocker arm assembly.

muffler man

I wish I knew as well. I found out about the Honda OEM Air stopper tool. I figure I will ask if he has one in handy, if not i will purchase one and tell him he needs to use when degreeing and the Helms manual will show how to apply the tool.

Bb's are the best bet. When you slide out the rocker arm shafts, slide them out just enough to remove the number one cylinder rockr arms.

found this thats a good vid

Someone else beat me to it

I use to swap the pins between rocker arms and that would also lock them.

Thanks Tonio (and the guy that posted it) for that video its good to know how to do it another way. Since I will have my engine on the stand and my rockers are already out I will just switch the dowels like 00Red_SiR mentioned. I will use the method in the video after its in the car.

96dxB16

This is how i did it

C_Rock77

So, do you take the pin out of another VTEC rocker and slide it in place of the shorter pin from the primary rocker?

Only problem I see with that is having to pull more than just cylinder 1 rocker arms out. The BB is simpler, IMO.

You only have to pull cylinder 1 & don't have to mess with inserting more than 1 cylinder's worth of rocker arms.

Now, if you had another pin laying around...that's another story.

If you swapped the pins, wouldn't that just lock 2 of the rockers?

I guess I just like the BB method. It works. It's simple. More than 1 way to skin a cat

96dxB16

Just swap the pins, locks only 2 of the rockers. Didn't have any BB's.

00Red_SiR

exactly....and only locking 2 pins doesn't matter when you're checking VTEC lobe measurements and only one cylinder for v2v/p2v etc.

bambam

Agreed. If you're using belbens kit, the pin swapping method only works on the exhaust side due to where belbens kit mounts. This method only locks two rocker arms. On the intake side, using this method, you'll be locking the vtec rocker and the rocker closest to the time belt, while belbens kit has the dial gauge mounted on the retainer closest to cylinder 2.

great info in this thread. thanks everyone.
