I have a stock b16 head and I bought some ITR cams that I would like to put in. Now I know I want to upgrade the valvetrain to accommodate the additional revs I am pursuing so I bought some supertech dual valvesprings for dirt cheap from a guy locally. Would it be ok to run the dual valvesprings with the ITR cams and stock retainers or are upgraded retainers a necessity? Thank you in advance.

 

Anyone have any insight or know where I could look to find out?

 

You should be fine with the stock retainers.

Thanks Steve, not doubting your answer but a second opinion always helps, so anyone else?

Has anyone had any bad experiences running dual valvesprings without aftermarket retainers?

 

anyone?

 

if you have 1st gen b16 retainers, i would not.

 

they are second gen b16a

 

just get itr retainers...do it right the first time so it wont cost more later. plus, itr ratainers arent that much. theres a set of itr/ctr dual valve springs and retainers for 100 bucks for sell here.

 

Oh what happened to yours when yours broke? Will take that into consideration.

 

Get ti retainers at the least. 9k revs.. you want to have a peice of mind that everything is ok....

Simple install.. and cheap.
