I'm planning on doing the MD 5/16" spacer and the Mrev2. My question is are there after market upper plenums that I can add to this setup to make the most of the setup? I figure I might as well do it all at the same time while I have it apart.

 

No. That is a very optimal combination. Anything more in that area would be a waste of money. Nice choice. Shows good research!

 

I have an 05 5AT coupe, which from searching leads me to believe I do not have the Rev Up motor. Can these be used on my motor?

 

You just need the spacer since you don't have a rev up motor.

 

Can I not use the Mrev on my car or it just won't be as effective?

 

mrev is just a non-rev lower plenum

 

I was unaware of that. So the lower plenum on my car is a better unit then what came on the rev up motors?

 

yes it is, also a mrev2 is a modified lower plenum, which you also wouldnt need.

just get the spacer and call it a day.

 

No that's incorrect. A non rev up lower plenum is just that. Motordyne's MREV is made using a non revup lower but is not the same thing.

 

With your setup you only need the MD spacer.
Don't bother with any other brand.

Call Tony from MotorDyne and he can answer any combination of ques you might have.
Tony's really cool, I called him 1/2 dozen times when I was looking to install my setup.
Really helpful.

The stock lower plenum from Rev up is better for high end and non-revup is better for low end.

 

Note: the average power in each gear, no matter how you shift, is higher with the MREV2/spacer combination.

High end, low end or midrange.

 

I spoke with Tony and he said that even with my non revup motor the Mrev2 will still show decent gains. He gave me some charts of dyno runs done on an 04 G showing the difference between stock, spacer, Mrev2 and Spacer/Mrev2 combo. Anyone with a non revup motor have this combo that can give me some feedback?

 

I'm sure someone will be curious to see the dyno links you refer to so I am re-posting them here.

Below is a comparison of Stock Vs Spacer Vs MREV2 Vs Spacer with MREV2. All of this testing was performed on a 2004 G35 Sedan with the non-revup engine.
