So i just picked up some crower stage 3 cams for H22a, was trying to go JUN but could not pass on these, hella good deal. These cams need lots of compression to work properly so I am hoping to use some prelude type s pistons along with single layer head gasket and MAYBE some flat top valves to get a little more compression. My questions are: Has anyone used these cams before, if so what compression u at? Will I be at the right ratio with type s pistons/thin head gasket/flat valves? Thanks.

 

Your setup sounds good man, I used them on stock compression and they definitely wanted more.

Anywhere above 11.5:1 would be great, if it was me I'd shoot for 12:1 or so, that way you can account for sketchy gas so you can street it.

 

So what valvetrain did you use? I knew when I bought the cams that I was not going to be able to run them on stock H22a pistons, even if they are the slightly higher JDM ones. How do they feel with the stock ratio? Did you even feel a difference? How does your car idle? Thanks.
