Performance Camshafts?

[red_dog007]

I have noticed that TheZStore has 6 stages. I never looked into a performance camshaft to help get more out of my L24.

Stage II does look the best for what I want.

Though what I am looking for is what are the differences from the stock to Stage II cam? Does it increase HP, and generally how much? Or does it just basically shift and/or strengthen the power band?

Man I need a high paying job. :hurt:

more lift+duration = higher flow = higher HP potential.

i have a stage 2.5 cam collecting surface rust if you're interested.....

The tips here include good info on cams.

In brief, more lift helps power but there are mechanical limits on what is possible. More duration shifts the power band to higher RPMs but usually cuts the peak torque a bit.

Stage I and stage II are the best matches for the RPM capabilities of an otherwise stock L24.

I have a new 480/274 stage 2 cam that I'll give ya for $75. That's half price from MSA.

but like any stage 2 or higher cam, you'll need new lash pads and valve guides, or something like that.

Stage 2 is the second stage of wussiness, still a very small cam. Yeah, there are coil bind and lash pad and valve stem seal issues to deal with, but it's worth it in my opinion.

with two different guys having new cams and wanting to sell them, i have to ask why did you change your mind about installing them? too much trouble, or what? i looked at adding headers to mine, and was told that if i didn't change the cam, that the headers alone wouldn't do much. still learning here and i had to ask.

I did a job for a friend who owned a few Z's, he gave me the cam for a payment. He bought the cam for one of his Z's but wrecked the Z before installing the new parts that he bought.

I already have a stage 2 cam, ceramic 6-into-1 header, 2 1/2" exhaust, Mallory Unilite Infra-red Distributor, MSD 6A ignition, Triple 40 DCOE Webers, and a couple other things. The cam really made a difference after the Header and ignition install. I LOVE the LOPEY sound and performance increase around 2500 to 5500 RPM. I get accused of having a V8 all the time while sitting at red lights.

I accepted the Stage 2 cam as payment because I was gonna build another motor but the finances are shot after school shopping for 5 kids.

Wait a minute, I'm confused. Does that mean "wussy is a good thing"? :stupid:

picked up the cam from ebay; waitied til i got a new head to install.

buuuut.... picked up a head with a stage IV cam/schnieder valvetrain preinstalled, so the cam is just sitting there now

EDIT- i should also add that it's a reground stock by american cams, so high zinc oil isn't as necessary. and it's a solid cam

SORRY, I had the cam on Craigslist for 2 weeks and it just SOLD.

Maybe next time,

Dave.

Hi

I also have a stock engine, the MSA 6 into 1 header and nothing else more, them it`s all stock. I would like to increase a little bit the horsepower of my 240z too, so what the best cam I should buy to do it?

how many HP, should I get with all that modifications?

Thank You

I see on the Z store the full valve setup for a set price, doesn't matter which cam you buy its all the same price. I am tempted to get a Stage 6 cam (although it'll be a street car and maybe an eventual race car) but I can't justify 6k-8k RPM on the road. But if I go into vintage SCCA racing with the Z and bail out on my BMW 2002 I'd feel like a fool to buy a whole new valve setup jsut for a a crazier cam... I want my car to be as race ready as a road car can get (minus the exception for dirty playing on the exhaust and going straight pipes no muffler (probably a bad idea)). My reason behind this is the Corinthian Vintage Racing club wants their cars to be period correct and original. This makes it manageable for a teenager like me so I don't have to get into some major stuff like a big fancy gear box; they wouldn't allow because it wasn't made in '72, we can only run the 4 speeds or if you find the rare BRE 5 speed. Thats ok though, from what I've seen, the one Z at the track only had triple Mikuni's, headers, MSD, and probably higher comp. for race fuel and kept up with the deep pockets of the Porsche owners which had the 5 speed. And the Z guy was even running the wrong gearing for the track, and stock cam. :0 Sexy!
