i wanted to ask you guys if a valvetrain upgrade is needed or anything else with these cams?

thanks

 

not really, maye some stiffer inner valvesprings

 

I checked the part numbers on the valve springs a while ago and the type s and base where the same

 

interesting... I'm curious though, how did you get the part numbers for the JDM springs?

 

are there any marking on the type s cams, my bro just purchase some and i think he got ripped off. when he put it in it made his car go slower. went from 12.9 on 91 to 13.0 on 110. please if you can post some pick of the cam. thanks.
