Are the MREV 2 worth getting???

[wide]

hi all,

 

Are the Motordyne ISO Thermal MREV 2 Intake Plenum worth the money?

 

thinking of buying both the MotorDyne 5/16" ISO Thermal Plenum Spacer (which i gather is a must) & MREV 2, but need to know im spending my money wisely.

 

thanks for any help. matt

I belive they have some benefit, but the plenum spacer is more noticable. I take it you have a rev up engine? If you do you might as well change both

not that i know of its an 06 GT but not the face lift version.

i just bought it so i'm a newbie to the 350z .

does that make a difference??? thought it was good for both???

thanks matt

It will fit your engine, and you should get a noticable gain. Another member on here will soon be doing this mod, so he'll be able to advise as to how good it is.

who???

GT4ZED, may well be doing this soon!! Here's a link http://www.envisionelite.com/Intake_Sys ... REV_2.html and i have 1 of these for sale myself.

MREV is only for rev-up cars ie 296 bhp. Write up here:

I think yours will be a revup if it's an 06 wide, just don't want you spending your money if the mod won't fit

I know it states that the mrev 2 intakes are only for the rev up cars, but, when i took mine off, i noticed that my '04' intake is identical to the '06' intake, apart (obviously) from the modification. I'm tempted to fit the mrev 2 on mine to see if it works, but if anybody knows why i shouldn't then i wont attempt it.

According to 350z-tech you get good gains from just fitting the mrev2 on its own to a mark 1. Although most with a mark 1 only fit the plenum spacer on its own. However if you have the mark 2 rev up engine you really need the mrev2 AND plenum spacer. Although Im sure someone else will provide all the facts.

Here's some pics of mine and the mrev2 side by side. There is no difference between the two apart from the modification. All numbers and lettering are the same and all bolt holes are identical.

perhaps you're confused as to what an MREV2 really are

 

An MREV2 is simply the lower intake manifold,from a non revup VQ35 DE with some porting done. The main reason it adds the midrange torque vs the REVUP lower intake manifold is due to the longer runner length. Generally speaking, long runners = midrange punch, short runners = top end power. The amount of these differences will of course vary by the specific setup of the car (ie cams/headers/headwork combo). The reason your '04 looks identical to the MREV2, is that it is idential (porting aside). This is also why they offer a core charge rebate if your car is a NONREVUP - they port these and resell them as MREV2.

 

In the US, and I suspect worldwide, the longer runner lower manifold (the basis for the MREV2) came standard on:

 

2003-2004 350Z's (all models); 2005 350Z's (except Track models with manual transmission and 35th Anniversary models with manual transmissions).

 

2005 Manual Transmission Track/35th Anniversary models, and all 2006 350Z's come with the shorter runner lower manifold as standard

Thanks for that Adam, does that mean i will get less of an improvement fitting it to an older model like mine? Would i be better off just fitting my spacer instead?

[wide]

from what i can gather all the older models have longer runs in the plenum chamber & the new revup engines have shorter ones, shorter = better top end worse midrange, so the benefits of the mrev2 are longer runs for the revup = better midrange, but the older model already have this so theres no need to use this mod. so the mrev2 is only good for revup engines.

hope this helps. matt
