Hey guys i just bought the MD spacer 5/16 for my g, i got a question tho. If i get the lower plenum from a 07 350z and install it in my 04 coupe will i see some more hp gains? sorry for my noobness

Thanks in advance

 

nope

 

can u tell me why it woulnt help?

 

no, your 04 already has the lower plenum that produces power gains with the 5/16 spacer.

You only need to replace the lower if you have a Rev-Up engine.

 

correction i bought the 5/8 blox spacer... not md.. dont know if it makes a diff

 

ill sell you my 06 revup lower plenum for 40$ shipped

 

i dont need to buy one.. the reason i was asking cuz a buddy of mine was asking me if i wanted his since he wrecked his z.. and i just wanted to know if it will help or not..

 

No it wouldn't help

 

Didn't the 07 Zs have the HR motor? If so the lower plenum wouldn't even fit.

Edit: Yes it did. Here's everything you could want to know and more about the HR motor. http://www.350z-tech.com/wiki/index.php/VQ35HR

 

lol because NO /thread

 

like Blue Dream stated above, 07 350z's have an HR motor, the entire plenum on those are completely different, so the lower plenum wouldn't fit. If you was to get a lower plenum from a Z with a regular vq35de the lower plenum would be exactly the same as the one on your car already. therefore not changing anything

 

While not as useful on a 2004, doesn't an MREV2 ported lower plenum improve flow a bit?

 

^yes - the MREV2 is just a non rev lower plenum that has been modified by Motordyne (port and polished) they remove some material from the front runner as well so as to not starve the front 2 cylinders of air flow like the stock design does. Plenum spacer helps w this starvation problem as well.

I have a non rev lower plenum w a 5/16" spacer on my Rev Up. Almost as good as MREV2 plus Spacer, I've read
