I have a 1st gen b16a head with stock valve train and GSR cams. I can pick up a set of low milage used CTR springs and retainers for a good price. My question is it worth it? I am soon to be boosted so I am wanting to keep my GSR cams,

 

yes its worth it, do it

 

yeah do it, i read somewhere that GSR cams are good for boosted motors

 

thanks...and yes I too have heard the GSR cams are good for turbo apps.
