I need to know if I have to install HKS Cams with HKS springs and retainers. Or if thats not the case, do i have to match the brands to get the best performance? And other question, on the Evo 9, could i install the cams without aftermarket springs and retainers. thanks

This is really old hat around here dude, you should search.

you wont need springs and retainers if you keep the stock rev limit.

HKS Cams don't have a big lift 10.2-10.8. You can run on stock springs.

People will say yes, no maybe so... It is cheap insurance to add better springs.

i wouldnt go with hks cams anyway....but with the stock rev limit you should be fine with the hks'

Honestly, if you're asking these questions, you shouldn't be doing the mods. Good luck.

smartass

lol..

You should prob. add what kind/brand/size your wanting to know these ?'s to...

dude, I'm actually not going to mess with the head for now because i just wanted to get some knowledge from the forums and getting smart remarks from you is not exactly what i had in mind so if you dont wanna help a bro out then why bother.

Well maybe you should'nt ask these ?'s for one if "YOUR NOT GOING TO MESS WITH THE HEAD" and if you wanna ask a ? that is that vague then your ganna get flamed and smart *** remarks...

ha ha i dont need someone telling me what i need to do or not, if what i asked is to the point where nobody would even think of replying me, then u should comment and tell me what i did wrong, otherwise you should mind your own business pal

MInd my own business..lol....what a tool!

I would say replace everything since you have the engine open some bit. Eventhough your car is fairly new you should replace or upgrade those particular parts of the motor at the same time. It dosen't make sense to do it one part at a time. I know your just doing cams but since you have the head open, upgrade your springs an retainers, you never know what direction you are going with the car. As far as brands it really dosen't matter just do your homework and don't buy crappy **** then you should be fine. Good Luck with the car and have fun!
