I was wondering if 2001 itr cams would fit in my b16a3? And what kind of gains that will give me

 

Ya they should fit but not sure if you need to upgrad valvetrain do think you need to but not sure. Basically any different cam besides the b16a's are an upgrade,b16's are not really aggresive cams besides the b. If you dont want to waste to much money but get a slight upgrade go with gsr's which are cheaper.

 

Yes the cams will fit. As long as you don't rev above the stock limit, you don't need to upgrade your valvetrain. They can give you mild power gains IF you get a tune.

 

stock limit of the cams or the b16?

 

the stock limits of the b16. you need to upgrade valve springs if you want to rev past your stock rev limit. ITR cams are a great upgrade from a stock cam

 

Ya what everyone else says not sure what I was thinking about the valvetrain but good thing people know there stuff. Like stated before you obtain the best gain from camshafts when you get tuned.
