Props to Klumzyee for not wasting your time and not making JBKFizzle45 feel lame for posting his Q by saying..... "uh, go search".
Thats the most retarded thing. IMO: If you don't wanna ANSWER the Q then dont waste the time or effort in a lame response.

The fact of the matter is most Forum Based Search engines are awful. I know my snowmobile forum has a minimum amount of letters to be used so since there are a lot of acronyms to search for it's almost impossible...and any time I search for something on here I end up wasting a lot of time.
It really makes my day to see guys take 5 minutes to post a thorough and thoughtful answer like Klumzyee did!

So talking about the MREV for the non-revup motors (MREV++??), has anyone installed one on an 05/06 5AT?? Also I was looking at the thread discussing this bt all the dyno pictures dont work anymore. Can someone tell me what kinda gains(rwhp) to be expected with the 5/18 spacer and the machined lower plenum on the 280hp motor. TIA

With the 5/16th Spacer (Vs. the 1/2), I believe you can still use a Crawford V5 Upper Plenum as well.

G35 6MT) rev up
The FULL mRev Kit includes a Lower Plenum [AKA part of the intake manifold that houses the runners].
To keep things simple.. How air flows from your intake tube to your combustion chamber can have a BIG effect on performance. (Hence why people Port and Polish heads or have a Head Job Performed on their fully raced rebuilt motor). Our intake manifolds have 6 runners that are housed in the lower plenum. mRev simply modifies the runners for more of a Street use.. From 2005 and up the 6MT (298hp) engine has been redesigned to rev up to 7,000RPM (Done by adding stronger rods and rod bolts) now for Infiniti to take full advantage of the new 400rpms they re-designed their intake manifold with shorter runners for more top end power. To gain this top end power they sacraficed alot of low end torque.. "eh? how?" think of your engine as a giant air pump.. now if a runner is longer it'll allow air velocity to increase.. because our cars are not equiped with a supercharger or turbo it depends on velocity to push air into the combustion chamber.. Cause Infiniti shortened the runners it caused the air to loose some of its velocity.. kinda like sucking on a straw.. try breating through a straw.. easy huh? okey now go get a toilet paper roll and breath through that.. Now do the same thing but while running. To keep it simple.. Infiniti allowed the engine to breath easyer at higher RPMs (more air) but in return caused it to loose some of that low end torque (loss of velocity)..
mRev replaces the long runners with shorter runners like the 03-04 BUT they add a twist to it.. If they were to simply replace the long runners into shorter ones you'll loose ALOT of top end power. but in return you'll gain ALOT of mid range.. around +25tq at 4000RPM-ish on a dynapack.. BUT you end up loosing alot of HP in the upper 600RPMS since the engine isnt getting the amount of air it is designed to (valve lift, cam shaft..) So to keep things simple.. you've turned ur 2005-06 6MT G35 back into a 03-04 6MT... to fix this motordyne's added a 5/16th spacer and machined part of the runners for #1 and #2 cylinders. by doing so they've increased the total volume of the intake plenum allowing the engine to breath at the upper RPMS (more horsepower). So why do we only use a 5/16 and not a 1/2"? the 1/2" will slow air velocity down too much and ruin that nice mid range torque and hp... but by using the 1/2" you bearly loose any top end if any at all (if i recall it was like 1-2hp) with a slight increase in mid-range torque.. since daily driving is done at 2-4k rpm and torque is what gets you out of the hole its not worth using the 1/2"
So to answer your question.. mrev includes
a lower plenum and 5/16" spacer..
add-ons include
ISO THERMAL KIT: manifold gasket and a Coolant control valve
Copper ISO THERMAL KIT: manifold gaskets and a copper throttle body heater
IMO if your in a warm area (that doesnt snow) get the mRev Plus with ISO Thermal kit.. you wont regret it

All revup engines benefit from the MREV and spacer combo. Then new NGK iridium spark plugs and an Uprev tune by me and it'll feel like a brand new car. Better throttle response, more power, better driveability, plus fun stuff like launch control, rolling anti lag, and the burnout mod. Plus map switching so you can have multiple maps you switch through on the fly

The reason the 2007 model wasn't mentioned is because you replied to a thread from 2006, before your car was even built
