Hey guys,

I found a sweet deal on a set of Cosworth 272's for the IX's and I was wondering if I needed to purchase any valvetrain upgrades like springs and retainers, etc. Could some of you guys running these fill me in? Thanks a lot!

 

im not running these, but from what i've read it is recommended. i have seen some pretty sweet deals on them lately myself though.

 

no you dont need valvetrains upgrades for the cos... it is a good thing to do them but you dont need to.

 

To clarify, I will not be revving further than 8K, and would like to keep boost at 22-23 peak.

 

then you are good to go

 

Thanks for your help guys!
