Skunk2 site says 03 to 05 . Whats different on the 06 ?

I thought all the VQ beofer 07 were the same ??

Im wondering friend has a 06 and will the plenium spacer work ?

 

If its the REVUP engine, a spacer, all by itself won't work.

OTOH if you use a MREV2 with it on a REVUP engine, a spacer works well.

 

How can i tell if its a rev up motor?? Its a friends car out of town and i ordered up a skunk2 spacer.

What can i look out for and why will it not work ? Ive done some search and turned up nothing

 

If its a manual transmission it is a rev-up. If its an automatic, just the spacer will be fine.

 

Few ok perfect. Yeah its a 2006 6 spd G35. So the skunk2 spacer will work fine. Im going to try to space the strut brace i guess to make it fit.

Were doing this and a AEM and a velocity stack.

 

Hello, did you read MotorDynes post? NO..the spacer is useless with the '06
motor, you NEED the MREV 2 for the spacer to work. Earth to JDMCRX are
you receiving this transmission....Hello!

Ok and read my post after that how do i determine if its a MREV2 motor ?? its a 06 manual

 

Ok i think im missing the point. this is not my car. Its my buddies. Its a 06 6 spd. So what is the MREV2 ? intake??

 

The MREV2 is a lower manifold that replaces the lower manifold of the 6MT revup engine.

Your friend has a 06 6MT so he definetly has the REVUP.

The REVUP lower plenum is a completely different design from the prior generation engine. Nissan fixed the "flow restriction" problem in the new design and it no longer benefits from a spacer.

But when Nissan fixed the REVUP lower plenum design, they also introduced another change. A change they sholdn't have made. They shortened the intake runners. And this changed the tuning frequency. Unfortunatly, they made the runners too short, so now they introduced a completely different kind of problem. The REVUP lower plenum has a poor "acoustic tuning".

The MREV2 is a modified lower plenum from the prior generation engine. It has the better acoustic tuning but it can still benefit from the use of a spacer. The modifications made by Motordyne to the MREV2 lower plenum allow it perform even better.

So the end result is that the MREV2 with a spacer outperforms either of the stock designs. Its basically a stock plenum with all the flaws taken out of it.
Its what Nissan should have done the first time around.

See the plot below. It is the MREV2 (w/wo spacer) dyno tested against the stock REVUP lower plenum.

 

Perfect thanks alot man. So i will tell my friend to look for a MREV2 lower intake manifold. Thanks alot We will send back the skunk2 plenum spacer today

 

so if i have an 03 automatic? does this mean that the plenum space by itself will work fine? im still not too clear on what to look for when buying the spacer.

 

Yeah the spacers alone will be fine for you throughthewire

 

^^you still need the spacer! If the motor is a revup model you need the mrev2 to make the spacer give you gains! However, if i were you I would return the skunk2 spacer and just go with all Motordyne. A huge majority of the forum that has done intake spacer/plenum mods has gone with Motordyne. Very reputable company

 

Thanks dude. I'll look into the Motordyne spacer. Is installing it a problem of could i do it myself??

 

If you can turn a wrench it's really easy.
