Plenum spacer anyone???

Has anyone heard of a plenum spacer for the 370z?

I'm not 100% sure, but when I looked at our intake 'plenum', it looked like it doesn't come apart with bolts like the earlier ones on the 350's. Looks like they glued/melted/whatever the two halves together on our cars. So there probably won't be a spacer, although I suppose someone could make a complete replacement.

I haven't heard anything about I don't think it has been mentioned either. Now I know from researching that the 03-05 350z got a HP bump from plenium spacer. Then the 06 I believe had fixed or basically was added from the factory which is why the hp bump went to 300hp then with the HR motors a plenium spacer did not add any gains. The VQVHR is basically a evolution of the HR so I don't know if it would have any gains or not from a plenium spacer.

The plenum spacer corrected an issue with the upper manifold design on the early VQ's.. the front cylinders suffered from starvation due to the original design, a plenum spacer would correct that, and offer some decent gains.

This design element has not been present for current motors, including the 370Z, so you won't see the need.

Reviving this thread instead of creating a new one...

I haven't heard anyone talking about Takeda's plenum spacer for the 370Z. I saw one of their teaser videos, so I was wondering if anyone thought about or inquired about it.

True statement, the starvation of cylinders 1 & 2 with the 03-05 models was the same issue with the 06 model which came with a reshaped lower plenum. Motordynes upper and lower plenum kit included a swapped out original lower plenum with a reshaped 03-05 Z33 lower plenum.

I could not believe the Z34's upper plenum is plastic. Reminds me of something Skunk or Kinetix would mfg and those were known to crack. Fingers crossed for a tight seal and cold air.

Interested, could you link us with the video?

The Z34 plenum looks like the same ones that come with '07+ 350Z HR motors. I don't recall hearing anyone complaining about cracking the stock plenum. Who knows what forced induction would do to it in the long run.

The Takeda spacers are different. It's not the "gasket" that surrounds the plenum, but it's the area with the 6 hole cutout into the engine. O_o I'm not sure how it all fits, but definitely curious.

Correction: I meant the Skunk and Kinetix plenum spacers were known to crack with the VQDE engines 03-06 models. I have not heard of a single HR motor plenum cracking.

Def interested in Takeda, doing a search know for any info. And if they produce any type of gains like the 03-06 engine models. Then I am in for more info as they were one of the best bang for the buck mods.

Interesting. Did it actually make it to production? I haven't seen any vendors announcing its availability for sale or anything. I could've missed it though.

Not necessary with the VQ37VHR AFAIK. Was a definite issue with the VQ35DE, but I think it was resolved with the VQ35HR.

Still want a complete manifold for the 37 though

Cosworth made a nice one for the DE, maybe we'll see one down the road for the VHR..?
