HKS is releasing another camshaft option for the EVO. Intake 280 duration 10.8 Lift with a exhaust cam 280 duration 10.2 lift. These new cams are being matched with their Step up cam packages they have had existing for some time for GTR's ect. No Pro step up kit was offered unfortunately which has valves and guides. For now only the 3 cams 264, 272, 280 and you can package them with springs and retainers. The larger cams cost the same as the older ones !!!

 

dang when are they coming out

 

280

 

will it idle louder than the 272's?

 

when are they released?

 

That's pretty freaking cool! They're definitely gonna need springs and retainers, though.

 

YAHTZEE!!!! good thing I haven't bought my cams yet.

 

They are out in Japan so we should be able to get them shipped over !!

 

for what around $550 a set?

 

can't wait to hear some results

 

Do you really need springs and retainers? What does HKS say about that.

 

i am sure results will be pretty impressive for us big turbo guys! but springs and retainers are def. going to be needed

damn this car game. i have valve springs and retainers for my 264/264 setup (not installed yet). i guess when the 280's come out ill sell the 264's. i have to have it.

 

You should not need springs and retainers for this cam set. The valve lift is no different from the other two sets, only the duration. What you WILL need however is a cam gear set.

But going to a substantially longer duration set may not be in your best interest. Bigger is not always better. Be advised.

 

Man, I looked closer and you're right. They're still keeping that same lift with those 280s. You'd think they'd get a little more aggressive with lift if these are supposed to be their "hot cams". Meh, well.
