Hey Z1. ETA on those headers?

SPOHN

I do know a lot of shops use a 350z lower manifold. That's one thing.

Now Z1 will not tell anyone anything about this there personal mod. So months ago I decided to find out. After many talks to other shops and research it came down to ONE of TWO things or BOTH. As I said before the 350Z lower intake manifold is one. I did learn that Z1 only charges for labor for there mod. So that got me thinking. Do they swap the 370Z LM for the
350Z LM with a even core charge? Maybe that's one of two. But after discussion with many shops and researching all NA mods along with FI mods that deal with vacuum/ pressure it comes to my conclusion that the PCV valve check valve is being bored out and when combined with a tune the extra power is extracted. Tell me I'm wrong?
