i recently bought these cams and i really didn't look at it till i got home seller told me they were hks 272. I was looking at em then realized they werent hks brand so i need to know what these are. If anyone has an input of what these cams are please let me know would be happy to know before i drop in.

 

are these evo 8 or evo 9 cams? I don't remember if my oem cams had those counter balance weights, but my Tomei cams looked like those were grinded off. I don't know if aftermarket cam manufacturers generally grind those off or not though.

 

Those are Evo 8 cams you can tell by looking at the ends of them. They look like cosworth m2 cams to me and it says [m]2 on the end of one of them. If they are m2's then they are 272 cams with 11mm lift. You need to upgrade your springs for these cams if I'm right.

 

If your talking about the 2nd pic I think that says [11] 2. But if they are cosworth they will have a laser etched cosworth and serial info on the black portions. They may be brian crower bc0112 cams. I would contact brian crower or another of the cam companies and see if they can help you pinpoint the brand on the identifying marks and provide the specs for them.

 

they are 8 cams

 

Yes thanks for the input i might just have to do that im scared to drop them in with out knowing if i have to upgrade valve springs and retainers

 

Yeah I would be too, good luck.

 

They look like stock cams.

So they could be a Delta Regrind based on the HKS 272 Cam grind.

Measure the base circle of the cams. Most 4g cams have a base circle of 1.180

Delta regrinds have appox 1.140 base circle.

 

Time for a visit!

 

i thought stock cams had the holes on them these dont unless there are different kinds? im very unsure

 

visit where? lol

 

The big give away that they are stock cams if the letters I and L behind the #1 cam journals.

As far as I am aware there is no new aftermarket cams that come with those markings

What holes are you talking about?

 

all hks cams have hks stamped on them , what size is the bolt hole in the sensor end of the exhaust cam they look like stock evo5/6 cams

 

i just saw a couple of pictures with an evo 8 cam with holes in em like these http://i219.photobucket.com/albums/c...oFSPics093.jpg

but thanks alot for that link that helped alot

 

Why do people have to be like that why cant they be upfront with another fellow evo owner and not rip him off. Thats BS,
