to those that have a evo ix with cosworth 272 cams did you upgrade ur valvetrain, lifers and head studs. curious to know because i have these cams and want 2do everything correct

 

+1 ^^^^ id like to know 2 befor i get them

 

I believe you need to upgrade your valvetrain if you are tuned and revving over the stock limiter.

 

from what i understand, cuz i want them too. If you are going to keep ur limiter to 7000 rpms, you will be fine, but headstuds, valvesprings/retainers and headgasket would be a safe way to go, i think.

 

yeah im gettin retainers and springs with my cosworths.........you should anyways since you will be working in the area. i might even do my valves and pistons

 

You will not NEED valvesprings and retainers for there lower lift cam. I would highly recommend headstuds.

If you are doing something like an M3 that has a high lift you do need to do the springs and retainers.

wat about jam non ticking lifters

 

you should be fine as long as you're not revving over like 7500rpm...

 

these cams have been proven to be fine on stock springs and retainers up to 7800 rpm

I believe that is the rpm cut off TTP uses and they push these cams

 

should i run headstuds

 

since u will have the cams out definetly replace the head studs cuz u will be working in that area anyways. i have the m3 cossies. i purchased the spring and retainers along with the head studs and new head gasket. i will be taking my head off for machinework and 1mm oversized valves. but if u just want the cams installed u will be fine without the springs and retainers just have them set ur rev limiter to about 75-7800 rpms as everyone else has stated above
