Got this from:

http://your.bamawisp.net/maxima/wiki/index.php/VQ30DE


The VQ30DE became the benchmark V6 engine throughout the world making the Ward's 10 Best Engines list for many years. Though similiar in external appearance to the VE30DE from the 3rd Generation (92-94) SE Maximas, the VQ is based off an all aluminum design with microfinished internals for smooth operation.

The VQ30DE did not feature, like its older sibling VE30DE, variable valve timing. Its light-weight design, however, made up for this deficiency and was able to punch out a nice fat torque curve.

There were three VQ30DE implementations for the Maxima - US Intake Manifold (USIM), US Variable Intake Manifold (00VI), and Middle Eastern Variable Inake (MEVI).

Nissan updated the VQ30DE by increasing bore and stroke along with intake enhancement - creating the 3.5L update VQ35DE for 2002+ 5th Generation Maximas.

So how do I tell once type engine I have? From the VIN?

 

you have a 1998 Nissan Maxima in the US. You have the craptacular USIM. Congratulations.

 

u have a 00vi if u have a 2000 Maxima or someone has swapped ir IM

U have a MEVI if u bought ur car from Iraq or swapped IMs

U have a USIM if u bought a maxima int he US and u car seems like it dies above 5k rpms

 

Open your hood and look I like the 00vi's black color.

 

gosh that makes me want to get a MEVI even more.

 

Go with the 00VI

SWEET! What prize do I get for it being the most craptacular of the bunch?!

 

I can tussle your hair...and call you count crapula if you want.

 

You mean like this?!?!

IS THAT A MEVI!? FTW?! WHERE CAN I GET THAT COVER!!!

 

.. it looks like you have decals on your mevi, the "nissan racing sport."

 

yeah amazing huh

 

Mevi Ftmfw

 

you know it haha. Still looks good budd, I like it.

 

00VI > MEVI

More area under the curve >

 

What is cheaper and easier to install 00VI or MEVI?

 

Ahh shucks! Does that come with a reach around?

BTW: What is that metal bar in the picture above that spans across the engine and bolts into the coil over tops? Why is that there?

 

3.5 > 00VI > MEVI

Dwarfs the competition

 

Get that christmas tree lookin engine bay outta here.

 

Front strut tower bar
Tightens up the front end to improve handling.

 

Obviously you have never seen my red engine bay

 

MEVI is going to be easier to install, but getting a bit hard to find. I believe Courtesy still sells them.

 

It's a front strut tower brace.

 

it says our US compression is 10:1, does the MEVI work better with the higher compression??? i wonder why they would have dropped the compression to 9.5:1 with that intake manifold....

i would assume it would make even more power if they used the same compression.

 

That's the same thing I was thinking...

 

Dont mislead him, its 15% performance and 85% aesthetic.

 

they have mevi in europe. german, austria etc. not only in iraq

 

I agree,....

 

Just about every Gen4 imported into New Zealand from Japan has the MEVI. The Gen4 that was sold new here didn't. Total difference of 29kw - just under 40 HP.

 

3.5 > 00VI > MEVI > *HICCRFPOC > USIM

* hamster in circular cage running for piece of cheese

 

Are you saying I should invest in a Tornado to make my car quicker?

 

Only if it has the upgrade,..... running hamster.

 

A running hamster would count as forced induction and probably yield you some serious gains. I wonder how long they can last in 95 degree summer temperatures...

 

You must do the Cold Air mod.........shaved hamster with ice cube on its back.

 

Shaved Hamster FTW. Plant a fan in front of him too...

 

anyone? insight?

 

According to the info from Post #1, it says that mevi puts down 5 peak hp and 12 peak tq than 00vi. How in the world is that possible? I thought we've already shown enough dyno maps that 00vi dominates mevi everywhere. Dude, weak. I was getting ready to do a 00vi conversion soon. Now this is really making me puzzled.

 

Well, considering how much money were talking about for a 00VI or MEVI, why not just look for a steal deal for a 3.5 from a junkyard and do a total conversion?

 

You've got it backwards.

 

just out of curiosity are you running 00vi nismology?..

 

Nope. Had a MEVI a while ago but sold it. Car is currently totaled. Got my eye on a sterling mist SE-L. A few local orgers are running the 00VI though.
