Camshaft S40 T4
 

Hi, I heard that the B4204S complete camshaft cylinder head is perfect for attaching the Volvo S40 T4 from the year 98. Do you need any modification? Thank you

NA cams are generally longer duration and higher lift that turbo cams, not sure if that's the case specifically with the t4 though.

there was a forum user, Vulvas40t4, who said he had it installed, but I can't find the link

It is important for me, since I have the car around 300 HP and I want a little more stretched
