Hey all. Sorry if this is the wrong place to put this but I'm brand new here. I have an evo IX mr with all bolt ons except turbo and its on e-85. Was wondering if I would be able to install cams safely without building the motor. I also had arp head studs installed when I switched to e-85. Currently I'm sitting at 373hp and 382tq. Any help would be greatly appreciated. Thanks !

 

Yes you can.dont have to build the motor.

 

I had a set of 264s without issue in my 05.

 

You don't need to build the motor but depending on the cam lift you may need non OEM springs.

 

For 272s would I need springs?

 

Depends on what 272's you install. HKS 272 no, kelford 272/jun 272 yes. It depends on the particular cam specs and lift.

 

Cool cool. Thanks for the quick answers guys! Real helpful

 

It all depends on how high you will rev your engine,what type of racing you will do.i have s2's on stock valve springs without issue.
