I don't know if this has ever been discussed before why is there such a significant price difference between the two? I have z6 head and I know I can use the y8 one with modification to timing and other methods, it would just be easier to buy the z6 one. I tried to search it but there are too many different search results trying to look it up. Anyone have good results using the crower 2 na cam in a turbocharged setup? I know ralph11sec had the zspeed copy of the crower but just looking for others.

 

I'm sure it will be best if you get a reply from somebody who actually has the cam. In the meantime, you may want to compare the cam to another that is designed for FI as well as to stock. NA and FI have different overlaps between intake and exhaust. My guess would be that just by comparing overlap between stock and an FI cam you should have a decent idea which direction you will be heading.
