MRev Manifold houghts

[Twizz]

Wassup guys,
I was looking to get as much power as I could from bolt ons before I go get a tune done. I have a stillen catback and an injen CAI. The car moves when you hit it off the line and when it starts to get higher speed. But in the middle, it kinda lacks power for my liking. I read somewhere that this mod would help with that. I don't know much about it though. Would some of you guys be able to give me some insight on this ? Thanks

With a full tune you might gain 2whp? Its a great mod for the rev up engine, which the M's never got. Only 6MT G35's and 350z's had it starting in '05. There have been varying reports of guys gaining a few ponies with it on the non revup's, but nothing concrete and for the price I would definitely NOT recommend it.

The Motordyne MREV2 manifold and 5/16" plenum spacer together could gain you up to 25HP, and with your other mods if you got these as well and then get it tuned you could probably gain quite a bit. There is another member here with similar mods and he gained over 60HP.

The MREV is a mod that benefits the REVUP version of the VQ35DE. No M35 has ever come with it. They come with the non revup version and do not benefit from the MREV enough to make it worth the $$. Please don't guess when giving someone advice... This topic has been beaten to death on other forums...

Im not. Also the newer, higher rev version isnt called a VQ35DE.

keep in mind, since the VQ35DE engine is the same as in the G35 coupe, it's easy to find used parts at a reasonable price -- just search this forum or other Infiniti Forum classifieds.

the Z-tube and stock air box (with or without K&N drop in) will do just fine
-- I didn't go the route of a CAI (stillen) since I've had prior experience with a 'similar' CAI when I had a modded BMW 325i (did an M3 engine swap) and installed the Dinan CAI. It looked nice (the Carbon Fiber tube) which the cone filter sat just near/behind the fog light. To me, it felt like it was a delay or lag for air to be brought to the engine -- during cruising, but at WOT and on the fwy it was good...Just didn't feel the need to try and get the CAI for the Infiniti...

NGK Plat Spark Plugs

the 5/16 Plenum spacer works great
-- great mod that provides mid and high end HP/TQ

the MREV2 with the Motordyne lower plenum gasket
-- improves upper midrange end HP

Berks HFC's
-- great mod: reduced weight compared to stock cats...better flow, provides aggressive sound to exhaust system and provides better torque

Megan Mid pipe & Axle Backs
-- easy plug and play, better flow and sound

Motordyne xyz pipe
-- replaces stock Ypipe for better flow (I currently have the xyz w/Resonator module, but waiting for the HFC on order) -- the HFC module will help with the Berks.

Grounding Kit
-- stealth mod that improved my electrical system as well as the transmission shifts

**Headers would be good, but will cost a lot for install...

Uprev Tune
-- you can do yourself or have your car tuned at a Pro-Tuner w/dyno
I got my car dialed in with Uprev and all the performance mods that I added is all balanced to provide HP/TQ, MPG, and proper Air/Fuel ratio...as far as measurable gains, I think after all the mods were installed and getting the tune, I gained at the wheels approx 63hp/35tq over my baseline run...

...sounds like you're on the fast track to modding your recent purchase --

There are two version of the VQ35DE. The non revup, which came in every automatic and the 03-04 6MT's, and the revup, which came in the 05+ 350z/G35 6MT's before the newer, high rev motor that you are referring to was released. That one is the VQ35HR.

The OP's 2007 M35 has the first gen, non revup VQ35DE, and will not benefit from the MREV. The M's didn't get the VQ35HR until 2009.

Im not going to argue about it anymore with you. I have posted dyno shows and experiences others have had, all you have shown is your words about how it doesnt do anything. Post some dyno shots of it not doing anything or go post somewhere else.

The VQ35DE and VQ35HR are two different engines, not different versions. The HR model not only has dual air intakes but also has multiple changes inside the engine that you cant see just by looking at them.

Dude, have you even read any of my posts??? I agree that the VQ35HR is a completely different motor. I'm telling you that there are two different versions of the DE motor.

****Update****
So I went to the shop on Monday, and I asked the person that tunes the cars and builds engines about this matter. He said that getting it wouldn't be a bad idea. He said that it would basically provide a better and more even middle of the power band. So I will look into getting this done. It's pricey though. The MRev itself is like 500 plus the install and tune and the planum spacer as well. A lot of $$$$

Of course he'd tell you that. lol. He's trying to make money to feed his family.

[seymore4]

assume 25% profit margin on the part = $120 profit
conservative 1 hr labor to install = $100

Minimum $220 profit for the shop, assuming you only have it installed. Add in tuning and its more like $500.

I agree with the guy at the shop, it can't hurt and if money grew on trees I'd say for sure you should get one. But I do not believe that the minimal gains justify the high cost.

Just look for a used one online.... G forums sell them all the time... I got mine used and paid less than 280.... If I remember correctly. I installed the MREV2 myself so my overall savings was great ... My gains were good and I really felt the difference before and after... LOL, I'm actually getting my car retuned as I'm posting!!! I'll post other pix of my current exhaust set up.... Prolly tomorrow

Lol. Well he wasn't really trying to sell me on it. I asked him n he have me an honest answer. They make more than enough money even without my measly $600
