Hey guys, I am thinking about getting one of those, and wanted to ask your opinions on which one to get. Whats the benefit of those and one on top of another. Thank you. Any info is appreceated.

P.S.Don't know if I am going SC or not later if that helps.

00VI is cheaper and makes more power at all RPMs;
MEVI is much less of a potential headache, especially with the install.

The 00VI takes more work, some of it custom, and they have occasionally been known to develop cracks (because they're plastic). MEVI just bolts up and wires up, and you're done.

Supercharging would exaggerate the power difference, i.e. the 00VI would be even better if you were supercharged.

 

^^+1. The 00VI is great for low, mid, and top end. Where as the MEVI takes power from the Lower Band and shift it to the top end.

 

Incorrect. The MEVI causes a loss in mid-range torque, not low-end. This is a common misconception.

 

I'm guessing u need to have a full exhaust system put in including headers,ypipe, and catback to get the full potential of an oovi rite?

 

an exhaust would help, but is not necasary, a y pipe would be the most beneficial, with my mevi, it seemed like I gained a little bit about 6000rpm when I put a catback on

 

what i've always wondered is is it easier to simply swap in a vq30dek rather than trying to retrofit the 00vi on the vq30de? i don't have much mechanical experience but if the dek bolted up easily wouldn't this be a better path?

 

What do you mean, "get the full potential of an 00vi"? You need those to get the full potential out of any engine with any intake manifold....

If it's super easy for you to pull your engine out, then a DE-K swap might be slightly less of a headache. Otherwise, the 00VI swap will definitely be less work.

 

Are you guys finding these 00vi's off of wrecked vq30de-k's or can you actually order the intake from a nissan dealership or something?

 

Wrecked/disassembled motors.

 

man it sucks i have called all the import junkyards around me here in minnesota. And they either have full motors ( which i don't need, unless someoen wanted to go in with me that needed the lower end stuff) or they just don't have any.

 

take note that the mevi is useless without an extended rev limit ecu.

 

Approx total cost to put in an '00vi at a shop?

i have an 00vi for sale if you're interested. pm me.http://forums.maxima.org/showthread.php?t=476727

 

so my JDM installed MEVI is next to useless, dang I'll have to complain to Japan.

 

i think he meant with a Maxima...

anyways for a few clams more you can get a 3.5 and drop that bad boy in assuming you do your own labor...

much less hassle than putting in an 00vi...(or so I've heard)

 

funny story actually my friend had an 00vi crack on him after he got it installed which he said was a "complete pain in the ***." Haven't heard much but supposedly he swapped in a 3.5 and said it wasn't that bad "not like that damn 00vi." lmao, I think he's still waiting on some stuff though, to be fabricated and for parts I'm assuming..

Could be a bunch of crap.

 

Installing the 00Vi is not hard at all. As long as you tag what hoses are what and do a little research you can install this in the weekend. It took my only 20 hours over 3 days to install this bymyself. I only had to go to the auto store once.

 

see thats where ur wrong....u still get a signifcant power gain from 4k to redline which is past 6k....so with out crazy stupid long gearing that 2k+ RPMs is stil signiicant when our cars make no power past like 5k and feel like dead dogs....now the extended rev limit of the JWT ECU only does help but it doesnt mean because u dont have it its useless....u just see an even greater gain

 

^^ Exactly. It's not that the MEVI doesn't do anything for you. It will make better top-end power than stock whether you have an extended rev limit or not. It just also happens to make a little less power in the midrange, so that's why people seem to think their cars aren't any faster "overall".

 

I have a full DE-K swap and I had a crack in my IM as well. Given where they tend to crack (somewhere in the back), it can definitely be a PITA to find.

As for whether the 00VI swap is more of a PITA than the 3.5 swap... I still don't see how that's possible, even if you have to track down a crack in the IM. The 00VI swap takes simple wiring and some minor custom work for the TB and IACV. The 3.5 swap takes all that, PLUS either timing chain and cam stuff (if you use the 3.0 ECU) or a LOT more wiring (if you use the 3.5 ECU).

 

 

Gah. I knew that, and somehow I typed low end anyway. :

Thanks... Post duly edited.

 

IIRC, there had been talk of the JDM A32's with MEVI having a different tune on their ecu's, so the loss in the midrange isn't as pronounced. All konak was saying is that without an ecu, Maximas with just MEVI installed haven't been any faster in the quarter mile. In other words, you spend ~500 and aren't any faster.

 

This theory still holds no water due to lack of proof (data)
Are you kidding me?

 

00VI Ownzs!!! Ftmfw best mod ever.

 

As I said, I read that theory and by me saying "there had been talk" I merely was introducing a theory that I had come across on the .org. Nowhere did I say it was fact.

Am I kidding? The last time I read the MEVI faqs (which was a long **** time ago), it stated what I had stated. I had also seen that statement reguarding a non-ecu upgraded MEVI equipped car before as well, citing that with the MEVI advantages and disadvantes, the power only shifts to a different part of the rpm range, and doesn't necessarily make the car faster in the quarter mile. (The only person to prove this theory wrong on the dyno, and not yet at a track, is Zack - and then there is people who believe it to be a fluke ~to generate as much hp as he had without an ecu upgrade~)

AGAIN, from what I've read on this website, and NOT speaking from personal experience, a MEVI equipped, non ecu upgraded VQ30 will make more power, but because of the loss in the midrange, overall acceleration remains almost the same.

I'm going to go read the MEVI faqs to try and find what I read before.

Edit...eh...unfortunately I can't search as well as I would like to in order to find the thread that I got my info from. Did DaveB run .3 seconds faster and 3 mph higher with or without an ecu upgrade? In that thread, it never stated his current mods.

 

the mid range loss is negligable compared to the 4k up gain...this should be in All Motor anyway

 

Anybody that says the mevi does absolutely nothing for you with out the extended redline has never driven in a Maxima/I30 with one installed... the difference is night and day.

 

OMG THANK YOU......every day on my way home i could jsut imagine what my car would feel like about 4k without the $hitty USDM manifold...it feels like it just dies

 

Exactly... it feels like it dies. I have a friend who has a 96 with every single mod I have except the mevi and I shutter when I drive it and feel that loss. Funny thing is that the fool nearly pisses his pants when he drives mine.

 

So, are we all on the same page now?

 

us 3 are......

 

IBjustbecauseyouguyshaveMEVI's

 

i dont have one....but i plan too

 

I still don't understand how anyone can argue with a relatively easy mod that:

1. Turns your roller-coaster power curve into a smooth, unrelenting build-up to a screaming top end
2. Makes power in a section of the power band where most intake and exhaust mods are doing their best work, thus increasing the benefit of those mods
3. GREATLY increases your total power potential

Sounds like a pretty good deal for ~$400 and no custom work.

 

but the 00vi makes more power than the MEVI even in upper end, right?
i'm just gonna use just the upper manifold but i havent decided if i want to buy the valve cover and coilpacks and stuff from the 5th gen.

 

It makes more power than the MEVI virtually everywhere.
