You will have to run lower boost, on non engine builds... if you are able to add boost at all. But more importantly are the internals better since they are raising the compression??

Maybe this engine has a better potential for NA mods. More responsive to NA mods anyway....

Could you change the head gasket to lower the compression to make it more FI friendly?

Finally Got a 2007 350Z at our dealer i got to PDI it. Then test drove it to the gas station. Most def has a faster pick up and it def throws you back into the seat and pins u there when accelerating. Still rides very smooth and handles great. You can def notice a diff.
