OEM cams: exhaust vs. intake?

[fiznat]

Just wanted to doublecheck with you guys before the head gets shimmed the wrong way: the exhaust cam is the one with the orange stripe on it, and the intake cam has the green stripe? Its always this way?

mod gets owned by searching :

How-to - Dual-Exhaust cam swap for KA24DE engines:

....

-Use two exhaust cams (the ones with the orange paint on them) from a 91-93 KA24DE 240sx (don't argue these are the ones you need, forget about the Altima myth).

Dang guys... lol... Someone was posting under my name, I swear!! I knew that already anyways jeeezz!!

Besides, who beleives what Greg says about KA cams!??!

[DjPantsSpecR]

our general rule of thumb is to NEVER EVER trust the paint on the cams.

but on every S13 KA (excluding 94's) ive opened up the orange is on the exhaust, but i've heard of other situations too.

if possible just double check the pin position and the first lobe position

Sorry for the late response (email didn't notify me ppl were responding).

And Foster, Greg just article'd the thing, it was posted by 98S14inAZ, we can trust him, hehehe.

And to pour salt on the wounds... one of the articles you posted (diy overboost protector on the 13th, Greg already article'd it on the 10th... DUPLICATE!!!!!)

Orange is warm color, while green is cooler. This is really stupid sounding reasoning, but you won't forget.

Well, then if one is not to trust the cam colors, what is a sure fire way of identifying your cams?

Measure lift and duration like any sane person would.......

[Chezedik]

Care to explain where one finds a DOHC degree wheel, and do you have a manual to tell me where lift is measured from?

DOHC degree wheel? Don't you mean crankshaft degree wheel?Summit racing comes to mind......I would suggest following the FSM.As far as measuring lift I just take them into my machinist (at Tito's machine shop) that does my regrinds, so i really couldn't give you the answer to that one...... Have a hard time figuring what cams go where sometimes, easy refrence.

OOPs failed to mention lift of valve which isn't determined till after I tell him what the specs are for shimming on my buckets, usually stock.

Damn I swear youre more up on this article thing than most of us doing the work are! lol

[InsanityInc]

You shouldn't even need a degree wheel. One cam should have lobes that are noticably larger.

[:: orion ::]

but i thought i heard someone saying that its reversed on s14's

Correct...

I've posted this MANY times in the past:

S13 cams: GREEN intake, ORANGE exhaustS14 cams: ORANGE intake, GREEN exhaust.

To tell which is which...Identify the INTAKE cam, then look at color.

Intake cam has the dowel pin at the 12 o'clock position when the #1 cam lobes are facing straight up.

It is supposed to take a special CAMSHAFT degree wheel for DOHC, the one summit sells is made by Mr. Gasket for Cam in Block designs.
