Evo VIII Cams in DSM? [Merged 5-9] 8 cam

[acidxrain]

My friend is upgrading the cams on his evo VIII so he'll be getting rid of the stockers. Would the stock evo cams be a good upgrade for my car (97 gsx)?

One major difference between Evo cams and DSM cams is the location of the CAS. It is on the exhaust cam of an Evo. You would have to have a slot machined into the intake cam on for a DSM.

Another is the fact that the intake and exhaust ports are reversed on the Evo. I'm not 100% sure, but I would think that the profile of the cam itsself would be different being that it is operating on valves that are at a totally opposite angle than the other.

If I were a betting man, I'd put my money on them not working without major modification.

Thank you for your experienced opinion.

The EVO8's cam can put in DSM motor. My friend did it on a 2g. He also use the EVO8's spring and retainer. The car pulls hard on high rpm. The degree for evo8 is 256 and 260.
The stock 2g is 23? something.

Here is the link for some pictures. I don't have detailed pictures. He installed 1g intake manifold, TB and 1g head into 2g. Then put evo8 cams.

Thanx.
What are the characters in the circles?

So they will also work with a 2g 4g63?

 

[dsm-onster]

Don't draw any conclusions until those numbers are researched...

Thank you very much, mitsumissle. I reversed the color on the picture and, on the intake cam, the number 130 is clear. Is this number there?

Stock evo 8 cams will fit with MINOR modifacation. At Torquefreaks (Thanks Jason) I compared a set of HKS evo cams waiting to be installed with my 1g cams. The firing order is the same on both cars, The #1 cylinder is at the cam gears. So the cam lobe orientation is the same. This means that the rotation direction is not a problem. The cam bearing journals are the same diameter, and in the same place. The thrust length/width is the same. The cam seal area is the same diameter. In fact the cams look very much alike. I offer this to you people, Look at crower.com's catalog they will show the stock specs for the evo 8 and dsm cams. hmm. I think the evo cams look good as far as an upgrade. HOWEVER the dowel pins that locate the cam gears are not in the same space.
NOW the hard part. the cam angle senser on the evo 8 is the 97-99 eclipse type were it screws into the cam. The evo 8 is screw in type on the exaust cam. Were the 2g cas screws into the intake cam. I recomend that you slot the end of the evo cam in acordance with a 1 g cam angle slot in the cam. GOOD NEWS, the cam bearing on the cam bearing cap does not actually use the whole width of the machined surface, So you can grind in a slot that will not screw up the cam bearing surface. The slot is 1/4 inch deep and make sure to center it. Now i have no easy ### to align the slot right but since a 1g cas is adjustable you can afford to be off. I will leave the slot machining or grinding to the brave who own dremels or a machine shop.

Since last time I wrote I got a few pairs of E8 cams when I aligned them on my head I was wrong about my previous line up method. I just mark were the lobes line up on the head with the stock cams. Then line up the E8 cams to match.
And when the stock cams are lined up the CAS slot is horizontal so mark the E8 cams at the cam cap part line and it should be very close to right on. and those cams in the previous pictures are E8 cams they have the hollow cam es along the camshaft.

PEACE!!!!!!!!!!!!!!!!

The Evo8 cams will work.You have to degree them i have 272s in my 1g. the cams are ground on the same blanks, the profile is the same .the only thing is that the pin placement on the nose of the cam is is wrong for a 1g and you cut for the cas on the intake cam. i will post picks of them in the head and side by side with 1g cams tomorrow when i get to my shop.

My car has been running for a few months now. With the evo 8 cams. As soon as i get the dsm link back I will dyno at torquefreaks, but it runs good, till the knock sets in, thats a whole other issue.

What process did you use to fit the CAS?

 

[Evo8MRdude]

I read some where that the Evo cams are upgrades to 1g stock cams-is this true? f so I can get a set really cheap. Even if its only like 5-10hp, its worth it. Or is it just a total waste of time?
Sorry, I tried a search, but came back empty handed.

Thanks-Jeremiah

Well, at least the Evo cams are hollow. I guess that you would benefit from less rotational mass.

IF the Evo 8's cams will work in an Eclipse, and that's a big IF (I personally don't think they would) The cost of retrofitting them to work will probably cost more than a set of HKS bumpsticks. If you're looking for milder camshafts, a set of Evo 3's or 1G turbo cams (for us 2G guys) cost chump change.

Ok since the evo 8 cams work. I was wondering what would the evo 8 272 be like in our motors??
The reason I ask is because I have a e8 272 exhaust cam.

Nice Info!!

Pin placement is wrong for the 1G? What about the 2G? Do you also have to cut for the '97-'99 CAS? What happened to posting pictures?

It should be the same as a DSM 272. IF the advertized duration and lift are the same. . . And i don't see why they would not be...

 

[Fox1486]

So I assume by reading this thread that there is only one advantage to putting in the E8 cams. Less rotating mass. They have the same specs as a 1g/2g cam? I'm sure grinding the cams down would prove even more helpful since it would still have the hollow camshaft to help.

 

[TurboTalonAwd95]

ok, 1st off I know there is a few threads on this already. I would just like to have a wiseman or some one who HAS installed them put in there comments and oppinions.

I've been doing some research and would let to know IF they will fit AND work properly.

Specs are as Follows...

4G63 ( Eclipse/Talon Turbo Camshafts)
Adv. / Dur. Dur. @ .050 Lift (in) Lift (mm)
248°/248° 200°/200° .349"/.350" 8.86/8.89


4g63 ( Evolution VIII )
Adv. Dur. Dur @ .050 Lift (in) Lift (mm)
248°/248° 200°/200° .386"/.367" 9.80/9.32


I have read and heard differetnt specualtions from differnt people some saying they will NOT work. But other have said they will work but the different is that the CAS on the evo 8 camshaft is on the Exhaust where the 2g is on the Intake. IF im not mistaken You need to use a 1g cas for the reason it is adjustable and has some give.

I know that the Evo cams are hollow so that creates less powerloss on the top.


As stated i would like some REAL!!! input. I dont need to hear any how you think they will or will not. i would like Proff on working or not and why.

Thanks . i recently got a set of "evo 8" cams and would like to know how much work it would take to put them in and if theres a big improvment.. also. does anyone know what the cam should say on the side? what numbers or lettering..

 

[prostreetdsmx1]

just the work and time it takes to do it isn't worth the gains if any at all. I have a customer that is running EVO cams in his DSM.

Invest the $305 on some Brian Crowers and you'll be happy.

We just make camchucks out of the stacks of stock EVO cams we have.

Could you or someone tell me the number sequence on the side of the Evo camshafts?
