degreeing cam on sohc?
« on: August 23, 2009, 04:31:38 AM »

ok so i feel like a complete dumbshit i know when i had aftermarket cams on my b-series motors i had to have the motor degree'd..

i have a sohc D16Y8 vitara in my integra.. i recently blew the ass out of my headgasket so i said screw it while its off ill buy the head ish. i got a crower stage 2 turbo cam and everything else.. long story short... is it needed to be degreed or am i smoking crack? i have searched and found nothing.

Did you compare the distributor drive end of the cams in reference to the keyway.  I'm under the impression that the stock y cams are cut incorrectly from the factory and have been compensated for in the p2p map. 

When switching to a aftermarket cam I'm fairly certain this issue is alleviated. 

But when it comes to degrees you'll shift the powerband higher by retarding it.  Lower when you advance it.  Make sure you adjust your distributor to compensate for the changes you make to the cam.  While you have the timing light out, point it at your cam gear while it's spinning that will give you an idea if you're in the ballpark...

Playing with cam timing on a sohc is way easier that a dohc.  No overlap/lobe centering/valve to valve clearance to dork up.

That's the most worthless writeup ever.  It's a SOHC with an easy-access gear, it needs a degree wheel and dial indicator like Spiker needs someone popping his hemorrhoids with a needle.

Did you compare the distributor drive end of the cams in reference to the keyway.  I'm under the impression that the stock y cams are cut incorrectly from the factory and have been compensated for in the p2p map.

You are under the impression that the p2p ecu actually functions like you think it does. Rather than pull timing if it senses knock, it adds timing if everything looks good. Also the y7/y8 cam gears make up the 4* difference between a 92-95 cam.


I'm all for rules & such, but I really got sick of the demanding porn in caps from ohmt. And for that matter, the rules aren't even listed. You will catch more porn with honey than vinegar... O0

Foowee does not have false ASSumptions.  Take a second look at the P2P maps and mentally process how to set the ignition timing on a D16Y, and you'll correct whatever impression it is that you're laboring under.

but if youve been reading hmt and posting since before hot-rex had herpes then i dont see a point in being a newbie and doing the "kewl newbie requirements" just cuz it has a different web address and shit is different dont make the people behind their computer any different. i have learned and taught hmt peeps... so yeah im not really intrested in the porn or as such.. im here for the reason that jeff frank made hmt with his first zc and t25... to learn and spread knowledge.. the whole reason hmt was invented not to gawk at my computer screen aimlessly about boobs (dont get me wrong its great, but i dont need it every half second)

im confused, timing is set through my tune not through preset mappage; right? im saying i dont understand how a sohc can need to be degree'd to the fact that a sohc has a set turn which couldnt be that far off +/- a degee or 2, where as a dohc engine can because the cams are exactly that in 2 seperate pieces.

jd - im sure you know the answer can you plz tell me ?

Mental process be damned, all 96-00 manuals specifically state 12* for d16's auto & manual, and 16* for b16. They didn't mis-print it twice in each manual from each publisher. Even if the cam is off 20* - if you can adjust it back, 12* on the crank pulley is 12*.

Regardless, you can't use ignition timing to make up for an advanced or retarded cam. Miscut keyway, yes, but it's going to run a whole lot different with the cam lobes all 4* off. And if it hasn't been taken into account, the cam gear keyway will be 4* off on the y8 aanyways, as it's gear is half a tooth off VS 88-95 gears.


When you think about how retarded it would be to re-design the cam gear & change the timing maps rather then have them tell the pre-production to change the keyway spot, it would not make sense to just set the entire timing map a few degrees back. I can't prove the way the knock sensor changes timing in a p2p, and quite frankly nor can you JD - not with the hard evidence you ask others to provide in these situations. If you can, I'd really like to know.

The more important thing would be to measure your p2v and v2v clearances. Then go on the dyno and play with the gear within your range and find what's best.

Degreeing really only saves some time on the dyno, especially on dohc's. Not much will be saved with a sohc because there isn't such as a wide range of degrees to mess with on either cams as there is with the sohc.

Post porn. No one cares if YOU want to look at it. It's not for your viewing pleasure.

Ok now I'll share my 0.02 Degreeing the cam on a stock everything sohc really isnt needed. Put the cam and crank on the marks and be done with it. If youve got mismatch of all kinds of dseries parts then get it in mechanical time to the marks and then do this. Set the low cam map to 12 degrees if it's a y set it to 16 degrees if it's anything else. You have got to have the block timing cover and harmonic balancer be from the factory together.  Ok with a timing advance light zeroed set the distributor. Then add in 12 or 16 degrees advance into the timing light and shoot the cam gear marks with the light. if it lines up your good if not then the timing belt is a tooth off their pretty much nothing else that can mess that up mechanically.

   Now if youve got the block decked and some after market cams and stuff you probably need to degree it. Or you could pull the J Davis and center the distributor and then shoot the timing light on the crank marks and adjust the cam gear to bring it into time.

  Mechanical timing and ignition timing are two differant things and one can't help the other d12crzy's way is how I would handle gettin the cam gear right. Common sense and shade tree engineering go way farther in reality then a long technical discussion between people who have no idea what their saying "honda tech"

Re-read what I disagreed with.  I was at no time arguing about the Y8 being indexed like a D15 or '88 D16A6 camshaft. 

Foowee's point is that the distributor drive *is* off, and you can think you make a point by saying that the P2P maps are minimum timing maps which was originally pointed out by me years ago, but when the ignition syncs at 12 degrees and the base timing on a corrected P2P map is 12 degrees holy shit he's right.

-To deliver mail in it.

-To go through the short line at Rallys/Checkers.

-To easily flick cigarettes at people at stoplights to instigate street races.

-To impress people on ht.

-To hook better.  If you put the driver on the opposite side of the chassis as the engine you will have a more equal distribution of weight across the front tires... 

-Birth control...  This one is a stretch, but if you experience a flywheel explosion, I doubt you'll be having anymore kids.

i get the david blane thing alot in life, i was him i wouldnt be working on my own car though.

everyone builds their car by choice and like certain things others dont, me personally would never make my car RWD unless that included the FWD portion to it as well. to each they own they say. i love being different, its why my car is rhd, its why it has a single cam in it. most people would agree on this site, your car defines you and i wanna be the person that makes you wonder "what the fuck?!"
