Plenum Spacers for the 08' 350z...are there any?
hey guys,
i know they def. make plenum spacers for 350z's. unfortuanatly i havent found any for the 2008. i noticed that you have to buy a MREV 2 Manifold TM for the revup engines. anyways, i think i have bit of a problem understanding this becuase of the air intake ports. there are two in my car 08' but the 06' and under only have one. if there are two in my car then the MREV wont be compatable with my 08' will it? and i really want this mod.
all i want is some added power for the price of a plenum spacer etc. i cant find it. i really dont need input about other mods, i just want this one specifically. thanks -john

Welcome to the forum John,
I think you're going to have a hard time getting an answer since your statements are contradicting. At first it sounds like you would take any mod that makes power as long as it were for the price of a plenum spacer:
But then you say you don't want to hear about any other mods other than a plenum spacer:
I can tell you the dual intakes and redesigned plenum of the 08 would not benefit from a spacer. You can be comfortable knowing that your car came with the plenum mod "built in" from the factory or start exploring other options...

we should make a pop up every time someone click on the hr forum that says: the HR engine does NOT need a plenum spacer, it already has one "built in"
but then again, we run the risk of: "can i put the stock hr plenum spacer on my de???"

There is no need to do anything to the plenum..... as said before it is very efficent.... I know you said about the same price, but you didn't want to hear about other mods well..... ask a dumb question. Anyways tests pipes will give a good gain on the HR.... it will still give power w/ stock exhaust, but an exhaust will open it up also..... have fun modding!!!

yea, i didnt have much sleep when i was writing the question. anyways, thanks for telling me that they pretty much have a plenum spacer built in...but if so, why wouldnt the horses be higher than the 03-06 models? the claimed 306 horses. cuase it seems to me that plenum spacers are suppose to add somewhere around 15 horses. so wouldnt that make the 07-08 models 321hp by nissan standards? just throwing out ideas. thanks

Don't get caught up in the numbers, particularly peak output. One reason, the SAE made the rating methodology for HP and Torque more strict in 2005. Nissan adopted the new standards shortly thereafter negating the published gains that otherwise would have showed up.
Just look at the comparison sample of verified drag times for stock Z's for proof of a power increase: https://my350z.com/forum/3035974-post7.html

the same bolt-on's typically gain more power on an hr than a de. but the only intakes to make power on the hr (thats known and proven) are the injen cold air intakes.

Typically the VQ35HR dynos ~20whp more than an equivalently modded non-revup DE. Assuming 15% drivetrain loss, that converts to roughly 24hp crank. You can add that 24hp to the 287 for the DE, to estimate the HR crank hp on old standard, or subtract the 24 from the 306 of the HR for an estimate of the DE on the new standard.
It's not a perfect conversion, but it gives an idea.
