would a gsr cam work in an ls head? and what kind of power would it make over the stock ls cams. valvetrain upgrade needed? just an idea that i thought could work...give some input

 

No. I don't know. Substantial.

Whole different ballgame.

You want to put vtec cams in a non-vtec head, you tell me how thats gonna work.

 

the vtec part of the cam wont engage but the duration and lift are different on the gsr cam so ud think it might work

 

Does a vtec cam have 2 or 3 different size lobes?

 

its got the secondary vtec profile

 

So 2 or 3?

Here, I'll help you...

 

i'll go ahead and say 3...but ur talkin to the kid with the ls

since the gsr cam wont swap in wat brand of aftermarket cams do u think would work best for street use

 

All stock vtec cams have 3 seperate lobes. One that it idles on, the "secondary" is a midrange lobe, and then you have the vtec lobe. If you're looking for ls cams I would look into Crowers or you might be able to find some JG's. Save your money and do a head swap, or do some mild cams and add a B16 or gsr tranny if you want your car to go faster.

 

Are you talking about grinding the vtec lobe on a ls cam or putting the whole vtec cam in. If the whole cam that won't work all you have to do is count the cam bearings the ls head has 6 and the vtec has 5 it won't fit. Dan

 

the bearing journals on the vtec cams do not line up with the bearing caps on the ls head..

your 100% wrong. it uses the 2 lobes untill vtec, then uses the middle lobe.

 

the man is right

Yeah no ****, I think I knew that guy.....way to state the obvious.

 

clean rice you are right all 3 lobes use seperate profiles primary secondary and high lift. as oppose to the ls wich uses 2 of the same.

There are only two different profiles. The two primary lobes are the same and then a higher lift and duration is on the vtec lobe in the middle there is no primary, secondary, and high lift. There is only two different profiles not 3. A non vtec on has only one profile because it uses no change in duration or lift.

 

on rainforest and cleanrice

 

Tell me there are only two lobes here on these cams.

This right here says it all you ****** stunna. Know what the **** you're talking about before you open your mouth guy. Jesus, talk about

 

I gotta bump this up just so people can see that these guys think there is only 2 lobes.

 

im sorry your feelings are hurt.

and also im sorry this concept is making your head hurt.


the 2 outer lobes are the primary lobes.

the single inner lobe is the vtec lobe.

quit getting all butt hurt.

^ he rreaaaaally wanted me to see this....

 

Yes Junior, I understand the functioning of a god damned vtec camshaft. It gets under my skin REAL fast when some ricer hopps on here and argues with people(you) like they know what the **** their talking about. I understand the term "primaries," but I'm seeing this as you and your sidekick Tyler saying that there are only 2 different sized lobes when obviously there are 3. And who the hell are the two of you thinkin you're gonna try to teach me something here?? You kids got a long ways to go, be careful who you're directing a "" towards, they just might be, and in this case are, worlds above you in knowlege. Please. Yes I do know that there are some cams out there that have only 2 different sized lobes, but we're talking about oem cams here...and they have 3. End this stupidity.

 

You have got to be ******* kidding me! vtec cams have 3 different profiles LS cams have 2 and only 2. The cam journals on LS and Vtec cams are completely different. They cannot and will not interchange. The reason they have 3 is for swirl at low speed. one valve opens farther than the other to optimize burn at low engine speed. When the Vtec is engaged all 16 valves operate off the center lobe. I have pictures too if you want to argue more.........Newjack

 

dont waste your time with the "vtec" bullshit. Buy a set of crower 404's and be done!
