Ok - So howcome there are no spacer talks for the Z?
 

I know that in the VQ35 community - a very cheap and effective mod was adding a 5/16'' plenum spacer from companies like motordyne etc etc... how come the G37s and 370zs have no mention of this sort of mod? I am assuming our VQ37 engines also have an upper and lower plenum.

Also - I havnt seen anyone make replacement plenums for the Z / Gs ... what gives?

I believe that the 350z had more restriction in their intake plenums. They fixed that issue with the VQ37, so a spacer is now ineffective.

ahh i c... but with more breathing mods + more tuning.. you think it might start to show its limitations?

I think that has yet to be seen. It's possible, but it definitely isn't going to be a cheap and easy mod for quick HP for the VQ37

Ahh - Ok - Yea I was just wondering as the G37 has been out a whiles now and there is NO talk of anyone doing that mod... I for one loved what it did both response and sound wise to my G35

a lil off topic..but i would love to see motordyne make an exhaust for the 370z...they seem to get good reviews in the "other" forum

If I am not mistake, I believe the plenum on the VQ37 is a single piece now bonded with an adhesive... I believe I saw an image from Forged when they dismantled a VQ35HR and documented the changes from the DE series.
