I was wondering if I got these cams for my b16 head if I would need to upgrade my valve springs? On a budget and don't wanna do it if I don't need to. Any input would help thanks

 

yes

 

 

type-r valvetrain would be sufficient? no?

 

no. Stock cams=stock valvetrain. Performance cams = performance valvetrain. ITR= stock

 

lol technically its an upgrade for some cars

i know forgot isnt the tuner 2 the biggest cams you can run on ITR valvetrain before upgrading?
i think skunk 2 said its recommended but not required for tuner2.

 

Tuner 1 cams are the largest you can run on stock or ITR (stock) valvetrain. Tuner 2's and up are all performance valvetrain. Even then, you can only run the pro 1's on the tuner series valvesprings, pro 2 and larger has to be run on pro series valvetrain. ITR cams are the best "stock" upgrade you can do before you go aftermarket performance but they are still considered to be stock parts.
