How can I tell if I got a 91 cam?

Hey guys!

I recieved my new cam today (supposedly from a '91).

The markings on it are: 13001 93140
8 M B(?) LYD 8 D

How do I know that these are actually from a '91 car? Thanks!!!

I had the same question when I bought mine a couple of months ago.

I could not tell the diffrence when put next to my 99 intake cam..
But I did notice the diffrence after I threw that bad boy in the engine

hit 4000 rpms and you'll know what I am taling about.

Haha,

Did you install it yourself? How long did it take?

Yes I installed it with the help of my father...

Install took about 1 1/2 hours with the correct wood jig.

May be a n00b question...but what does the 91 intake cam have over the stock?

10 degrees more duration.

It adds about 7hp to the wheels. Nissan changed the cams to a 'lowport' around '94 to meet emissions better.

Easy swap, so they say. Worth the power for the $. I got mine for $55 bucks to my door.

"Install took about 1 1/2 hours with the correct wood jig."

Ah yes, the infamous wood block that's supposed to keep the tensioner in the right place. I'm glad you got it to work, because when I made one it didn't work. If you ask me, it takes less time to remove and reinstall the damn tensioner than to make that wood block.

lol ,

That is so true...
I didn't havw a wood block for the 91 intake cam install and everything that went erong did.

So when I installed the S3's i said I might as well make the wood jig because I had a little wood block sitting around..

So what kind of wood jig do I need? You guys are starting to worry me

can't you just ziptie the chain to the sprocket?

Don't worry about the wood jig, take the tensioner out and pop it back in after you're done. However, before you pop the tensioner back in, push the plunger back in and hook it, so as to hold the plunger back. Insert the tensioner, and after closing up everything, manually crank the car (if you cant, here is an alternative: put the car in 5th gear and push it 5-10 feet).

For easier-to-understand removal and installation instructions, click the link below:

EDIT: take the tensioner out before removing the VC. That way you won't risk anything falling inside in the engine.

Here goes the wood jig I made

Harris · Jul 30th, 2003, 08:54 AM

Not bad actually!

However, I still say its better and safer to just take the tensioner out, IMO. Its a better precaution, with no chances of anything falling in.
