ctr cams in b16a2 question


The type R springs are not stiffer by much. The point is they can handle the extra lift while keeping the same margin before springs are fully compressed. B16a springs with type R cams you have only 0,5mm (more or less) before the spring is fully compressed while you normally have around 1,5 mm.

Type R cams with A2 maps I bet you are runing lean (around 14 or more) past 6500 - 7000 rpm.

With the type r cams and a2 ecu was idling fine with b16b type r ecu idles at 1600 cold and 1100 warm
 
"Best" is a relative term in cars. It all depends on application. Go do some research into Pros and Cons of Type R manifold over B16A manifold. Pay attention to where things give gains in powerbands and what you plan to use the car for.

The Type R cams will not be affecting your idle.

Ps doing research is not continuously asking questions. It is looking for and reading info that there is plenty of about.
