i searched and haven't come across a thread that answers my question:

can i use the motordyne MREV 2 lower collector in conjunction with the powerlab 3/8 plenum spacer on my 06 revup 6mt touring 350z. i'm assuming i CAN, since the mrev2 fits with stock angled spacer and the powerlab bolts onto stock parts as well.

also, how does the 3/8 plenum stack up against the 5/16 motordyne spacer?

 

The subject is about 8 years old and well covered. Seems that if a 1/4 inch spacer is good than a 1/2 spacer is better. And if a 1/2 spacer is gooder, that adding a upper plenum is the best of the best. Oh how I wish it was that simple.

 

 

Erm, the 5/16th spacer was found to be the best balance.

The 1/2 inch is available, however it's gains are right at the top of the rev range, i believe it doesn't gain as much mid range as the 5/16th does.

The MREV2 is a modified stock lower from the DE engine, i don't believe there will be any fitment issues.
