i like consistency so i'm going with Motordyne full bolt-on. the ART pipes will most likely go on last, next up is the shockwave v2 tdx exhaust

are you doing the install or paying to have it done? it's not that hard at all, and was actually quite fun to see those parts of the engine that you never do get a chance to see. just give yourself a full day to take your time and you'll be a happy man when you tighten up those last few spacers on the strut bar, close the hood and fire her up!

Just got my mrev installed....holy $hit. The car goes like a freight train. Unbeliveable.. Let me say it again.. Unbelievable. If you have an 06 MT6.. Its a must have. Driving back from shop and wreck'd house on a older vette.

Got it installed today at my shop However one thing my mechanic noticed before installing it was that some of the upper plenum bolts were lose i had installed the 5/16 spacer first two years ago and did it myself and followed the instructions so I don't know how they came lose...oh well, he buttoned everything back up and loctited and torqued everything again back into spec so all is good. like the guy above me posted, the car pulls like a freakin beast + the new brakes help me to stop on a dime

I recently installed the MREV2 and the spacer onto my 06 Rev-up~

I didn't notice much gains even at 4,000 Rpm, it felt close to stock but I dunno.....It might just be in my head~

The manual says to check for hissing or leaking noise near the engine bay area (After Installation of mod) and I think I hear something. My mechanic tells me it's the injectors pumping fluid that's making the sound.

I would really appreciate feedback from owners on this, do you hear a hissing sound near your engine bay?

I have an 06 with MREV2 and spacer (which I installed first) and the throttle response seemed quicker and more power, however I really felt more after I installed the Bassani exhaust seemed to respond better. Hope it works out.

how are gains with the MREV2 and spacer on NON REVUP 03-05?

Caledan

iTrader: (7)

You do not need the MREV2 for Non-Revup engines~ Just the spacer itself is good enough for gains~ The MREV2 provides minimal gains if not any for the Non-Revups~

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.
Also note on this plot here the MREV2 is referred to as MMP in the plot legend.










Also see this link to an independent test on a NON-REVUP engine. This test was performed by a forum moderator.

with the dyno sheet the gains and lost are diff from the 350z and the 4dr g correct? from the dyno there is a gain 13hp with the mrev v2 and space with the 350z

Yes, but its not that the results will be different specifically for a Sedan, it more of a demonstration of how results vary from DE engine to DE engine.

This is normal to see with any bolton.

By pasing inspection to you mean all 50 states. I live in CA and we have ridiculously high restrictions for smog. Please let me know thanks.

Erwin06Z

It does. Don't listen to nonsense like that man I don't care how many cars they claim to have worked on. Yes no matter what you upgrade on your car you never feel the full effect until it's tuned. Osiris reflash or w/e. But to say using a spacer alone on our motor is useless when knowing full well the tapering of the front of the intake plenum is robbing the two front cylinders of air is borderline noobish. Significant difference no lol but with mrev2 it makes a big difference. Either way use both

Oh, they both make differences, positive differences, used on their own, used together.

I'd say at least one of them is a must have on your 350z, no matter the year.

Sorry to revive an old thread but thinking about getting an mrev2 for my 05 DE. I currently have intake, catback, 5/16" spacer, HFCs, and Osiris flash. I'm guessing if I get the mrev2 I will have to retune.

I don't hear much of the DE guys doing the mrev2, is it that people just don't post or are they not doing it? Also, for those of you that are installing it yourselves? how difficult is it. I've done supsensions and audio work before, and I did do my own spacer. Getting my front brace/sway bar back on after the spacer was a real PITA tho and I'm not sure I want to go back down that road. Any advice? thanks.

I got mine earlier this year and it pulls so much harder in the mid range. I notice it the most from 3k-6k

F2CMaDMaXX

So, on a DE, yes, it does improve things, just not as much as it does on a later motor.

I would retune, yes, though i wouldn't worry about doing it immediately.

It's really simple, when you installed your spacer, and stopped at the spacer part, you just take one more part off, and then put the MREV2 back on instead. It's a good opportunity to install the heat gasket to help prevent heat transfer.

Thanks for your input. Much appreciated. I think I will put this on my list of winter mods.

I'd stress having your 350Z tuned after making any intake manifold modification - the MAF typically can't compensate for the increased airflow. I was running low 14's Air Fuel Ratio under full throttle with just a 5/16" Motordyne Spacer before Osiris tuning. Pretty lean.

Not saying it's the same as the MREV2, but I snatched a used non-rev DE lower plenum and went to work on it myself...took 5mm off of the front 2 runners and smoothed out all of the casting lines.





Mine is an 03 DE, but still saw a decent gain throughout my entire powerband. Both HP and TQ. I'd say it's definitely worth doing if you're running a Revup...I'm curious to see what my plenum would do on a Revup.

I was also running a 5/16 spacer during that dyno testing both before and after the plenum work. Only change was the plenum.
