As I have had period of inactivity for the past couple years, I have not come across that post;
Thank you.

 

I don't think anyone was saying that, or at least I wasn't. Your cams have more lift and most likely more duration than the Equinox cams, and don't have the phaser differences. Your cams w/o the fuel lobe are 5-6 times the cost of the Equinox cams though. That's all that's being explored here. It could be a ZZP Stage 0.5 cam that has the fuel lobe change and is half the cost of the Stage 1... that would be tempting .

Edit: and I just saw Matt's 2nd post about the actuator being reversed.

 

OH crap!

I posted on page #2 over there!

whoops!

As a point of disclaimer, but not totally trying to excuse my memory lapse, I was in the early stages of wedding talk at that time...

 

Before coming to this thread, I was looking at their cams, and for the stage 1, the enlarged HPFP lobe was a $150 option (iirc).

Matt ftw lol. Finally someone in here that knows this ****. Because I didn't know about the oil holes either, I was just going off the measurements that were taken.

I'm on here everyday and I've never came across that lol.

 

I'm not claiming ZZP's cams to be the Equinox cams in any shape, form, or fashion. I'm not comparing ZZP's cams. I'm comparing to STOCK LNF cams, and the intake cam I have in my car aligns perfectly. I have the stock LNF exhaust cam in the car.

 

Right the 2010 DI intake cam is different than the 2011 and up. It lines up perfectly. But with no fueling lobe I think its a waste of time

 

It was worth a try I believe. I'm wondering which one I have. It has the fuel lobe and I swear everything lined up. I will get out there and check it again tomorrow.

 

So which year is the year that lines up perfectly with the lnf?

 

I've heard the 2010 for the one that fits. I heard it had a slightly better fuel lobe so looks like there is a lot of clashing opinions here.

 

My curiosity got the best of me today, so I decided to compare the intake cams I have. I didn't compare exhaust cams because I've already established the Equinox cam I purchased has less lift. I have pictures.

Before I begin, THE LIFT ON THE FUEL LOBES ARE EXACTLY THE SAME. I did not worry with taking pictures of the lift on the two because the HPFP is already installed on the head, and I'm not fooling with removing it.

First, I will address the point that Matt M brought up in one of his posts, which is the oil holes in the end of the cam not aligning with the key hole and the cam lobes aligning. The cam installed in the head is the Equinox intake cam that I bought. The cam on top is the stock intake cam.


Here are more pictures of the cams showing the lobes are aligned.





Sorry for the large pictures. I will show the cam lobe lift difference in my second post.

 

Second, I will show you the difference in lift between the stock LNF intake cam and the Equinox intake cam installed in the head. The first pictures are of the Equinox intake cam at 0 lift and max lift.

Equinox intake cam at 0 lift:



Equinox intake cam at max lift (.245"):



Now for the stock LNF intake cam, sitting inside a removed stock LNF head I have on the shelf.

Stock LNF intake cam at 0 lift:



Stock LNF intake cam at max lift (.237"):



Again, this is only an intake cam comparison. I have not compared duration because I do not have a way to do so here at home. I compared exhaust cams, but the Equinox cam had less lift from the beginning. Currently, I have the Equinox intake cam and the stock LNF exhaust cam installed in the engine. The engine is not in the car currently, so I cannot provide information pertaining to that.

 

The cam part #'s that I purchased are:

2010 Chevy Equinox LS
12608300 - intake cam shaft
12604896 - exhaust cam shaft

I purchased these items from gmpartsdirect.com.

After I looked some more, the intake cam on the 2011 Equinox has a different part number, and it's more expensive. Here's the part number:
12634207 - intake cam

I don't know what the difference is and why it's more expensive than the 2010 intake cam. According the GM Family II engine - ecotec information, the 2.4 liter Direct Injection LAF is the same in the 2010-2011 model Equinox. The intake cam between the 2 have different part numbers. I'm not really willing to spend the $100 to order one, as I'm satisfied with the ones that I have.

The 2012-present year model Equinox have the LEA engine, which is also a direct injection engine with slightly lower compression ratio and E85 capability.

 

My buddy has one too. He got the 2.4DI motor. Runs pretty good. They should have tossed the LNF in it though.

I recently saw the new malibu has a 2.0 DI turbo with just about 300 ft-lbs stock. We will be in the market for a small suv soon and I definitely want one with a 2.0 T. Period. Haha

 

Definitely! Once you go boost, you can't go back!

 

Bump. No one cares to discuss this after I've provided picture proof?

 

I'm down lol. Thanks for looking into this, but I am a little new to trying to understand this. So are you saying the fuel lobe is the same for the 10 equinox and stock lnf? Also, what does the lift change? Better airflow?

 

I may gonna do this. I looked up in Ebay that part# you had posted up and only for that Equinox intake cam for about $80 and shipped! That's crazy!

 

Interesting. However consider that ZZP has tested their cams and determined what will be good for the engine. Not saying that this cam isnt different, I am saying that ZZP has designed a cam to make more HP. If you are serious about doing cams, save up for one that will help you achieve your goals. My $.02

 

x10000

I don't get why people are so quick to look for a cheaper untested alternative for such a critical component as cams lol ZZP already did the R&D, they gave the specs and performance gains ect.

Sure you might find a super cheap stock cam that's compatible, but it's not specifically designed for the lnf and ultimately it's not going to perform as the stage 1 cams will.

Why not support the company that's been pushing the boundaries for our platform, whom already come out with stage 1 and 2 cams with proven gains and R&D behind their product?

This is all IMHO, not trying to start an argument or anything, this is just how I see this cam situation I guess. I personally have stage 1 cams with the lobe and will probably get the stage 2 or 3 if they ever come out sometime down the road...but I'm going for redemptive all out power kinda sort of so yea lmao

Good discussion

 

I'm not cheap by any means guys. I'm definitely not out to smear any vendor on here. I'm simply experimenting. I understand supporting the community, and I'm not against that. Don't get me wrong.

However, I also like to explore all of my options and post what I find. I'm not going to sit around and be a follower. I don't see anything wrong with installing a cheap set of improved "stock" cams. I look at it as the "airbox mod" of doing cam work. How many people do you think on this forum have a huge hole cut in their airbox for more airflow? That's just one way I look at it.

Thanks for all of the input.

 

Because Cobalt community........That's why half the ppl with high horsepower cobalts can't get out of the 12s, won't spend the money on proper setup.

 

Because Cobalt community. 95% of this community will not explore options like this. ZZP is not the only group of people able to R&D a particular product, especially something as important as cams. I mean I understand folks would rather just go with the flow of everyone else.

Go outside of this community and you will find individuals, as well as shops of course, doing their on research and finding what works best for their vehicle.

 

oh i agree there are other shops, such as FMSR doing his R&D. but like you said, people would just rather go with the flow of a shop that has been around for a while and doing this longer. this car is still a young platform so give it time and im sure there will be more serious shops that pop up doing different cams and head work type things, but even then, zzp will still take most of the business im sure. the cobalt community is too cheap to spend money on serious ****, there isnt enough demand for other shops to invest time into this platform in my opinion.

 

Interesting. We have several 2.4 DI cams here and none have the correct configuration. Is it only the 2010 that did fit? I would be happy to map them out for duration and valve timing if someone wants to get one checked.
