im putting an engine in my 97 max. the engine that im putting in came out of a 2001 max. i know what your gonna ask and the answer is no... im using the stock intake manifold not the vi. i hope to be done by next friday. ill keep u posted.

 

Take Pix!!

 

Why did you bother then? It's the same engine other than the VI. Did you get a good deal on it or something?

 

i can take some pics but i dont have a scanner. and im lazy. and i dont know how. if someone will post them for me then pm me your mailing address and i will mail them to you.



by the way my other mods are unorthodox flywheel... unorthodox clutch... unorthodox underdrive pulley...stone racing headers...cai...warpspeed y-pipe...catman cat...complete 2.5inch exhaust

 

yeah...i failed to mention i bought it on ebay for 300 dollars. my old engine got 2 holes in the block and 3 rods hanging out. new motors only got 17000 miles on it.

 

Haha...

Without it's VI there's absolutely no advantage to going with the 5th gen engine. But i can name a few disadvantages off the top of my head:

1. No ECU upgrade currently available. That may change soon with TS but we'll see.
2. Less intake cam. (Has slightly more exhaust cam but with the w/out the VI that advantage is negated)
3. No ECU upgrade currently available.

What i plan on doing in the next year or so is purchasing a VQ30DE-K and transfering the VI and the exhaust cams over to the 4th gen engine.

 

i didnt change my ecu...i kept all the stock sensors and wiring harness so i can still upgrade through JWT if i want

 

Cool...

Any particular reason why you kept the stock intake manifold on there??

 

i need my car back and dont have time to fabricate what it takes to make the new one work but i have the setup still so maybe in the future ill do it.

 

So you just put in a replacement motor

 

it has better valve train correct?

 

Forgot where I read it but in the DE-K like 40 or 50% of internal components were changed from the 4th gen. But yeah, why didn't you just do the intake plenum as well? It's not like it's hard?

 

this is the exact same thing everybody was asking me when i had the 2k motor in my car. props to you man for doing it. nothing really that hard about except some hoses and less problems cause you are using a 4th gen IM just like I was. But i always wanted to put the VI on the engine but never got around to it. And you guys might think that it is just a replacement motor, but internals are different on 2k-2k1 and 4th gen engines. the funny things is there is another 4th gen max in front of my house and my old engine in my garage. lol. another swap maybe this time with the VI? just take it to the track though. props to you again man and get some pics uploaded here.

 

What exactly are the differences between the 5th gen VQ30 and the 4th gen VQ30

 

40%-50% different...care to explain?

 

They can't. The differences are minor.

 

i hear that the cams are diffren so im going to measure the size of the lobes on each one since i have the engines sitting next to eachother and i have to transfer the rear valve cover anyway. i let u know what i find using a micrometer.

 

It's already known that the VQ30DE-K has slightly less intake valve lift but slightly more exhaust valve lift than the DE. The duration, IIRC, is the same for both engines.

 

Advantage is obvious! Try finding a 4th Gen VQ with so low miles!

 

okay so ive measured the lobe heighth of the cams on a 1997 VQ30DE...my old engine...and the lobe height on a 2001 VQ30DEK using a micrometer and here is what i came up with


1997 VQ30DE intake cam 44.01mm
exhaust cam 43.98mm


2001 VQ30DEK intake cam 44.05mm
exhaust cam 44.51mm


take into consideration micrometer error and worn parts and i would say that the intake lobes on both motors are the same height and the exhaust cam on the 2001 is .5mm longer
im going to post this on a new thread and see what people say

 

internals are the key to the more horsepower rating on the 2k-2k1 maximas and the VI also.

 

What exactly is different as far as internals?

 

Mike, i guess you forgot so quickly your a noob to this maxima thing, why dont u pay attention and maybe youll learn how to make a car go fast. the different internals make it go faster silly.

 

The rotors are bigger with a stronger apex seal...retard

My DE motor has 161K on it and am also planning on going with a lower mileage motor and am going to go with a 5th gen motor as well and plan to use the VI.

Haven't kept up well with the guys that have done the VI swap, but what do you exactly need to get this puppy to fit and work properly under the hood?

 

i am not exactly sure because i kept the old intake manifold. but there is a huge 13 page thread somewhere on this site. you should search it and it will tell you what you need.

 

To reiterate what i already said in this same damn thread, no, the intake cam lift is not the same. The DE-K has less intake cam lift. Someone has already taken measurements of the lobe heights and posted a chart with the durations. Both engines have the same duration on the intake and exhaust cams.

 

i wouldnt lie to you or anyone on this site and i work on cars for a living so i know what im talking about and what im doing. i measure the cams w/ a micrometer and those are the readings i got. i saw the measurements w/ my own 2 eyes so nothing you say or do can convince me that the DE-K motor has a smaller intake cam. it wouldnt even make sense to have a smaller intake lobe because that would negate the advantage of having the vi anyway.

 

update my engine swap: i had to transfer the rear valve cover and coil packs. although i am keeping the coils from the DE-K motor on the front cylinders. also on the DE-K motor there is a coolant passage that runs underneath the intake manifold so i had to re route all of the vaccuum lines and one of the heater core hoses to accomodate that. the hose connects to the coolant passage that sits above the transmission on the left side of the block and connects to the coolant pipe that runs between the 2 cylinder heads. i hope to be blowing smoke by friday since im off of work. the drag strip is open friday nite so if i get it together i will let everyone know how it runs on paper.

 

You were right. They do have the same lift, it just the intake valves close 8 degrees earlier on the DE-K.

BTW your times won't really be any different, sorry to say. Most of the gains on the DE-K are from the VI.

 

good work so far. did you fab up a bracket thold all those hoses? i had to do that cause there was to many of them. you are going to the same stuff i went through. are you doing this at your house or at shop? are you alone. props to you man. cant wait till you get the # at the track.

 

actually i used the old bracket that held all the vaccuum lines i just had to cut and grind at it to make it fit. then i made all new vaccuum hoses to accomadate for the new location. im doing the swap at my work which is a GM dealership so every day after work i have been picking at it little by little.

 

well then you got the access to a lift and everything you need. i didnt have any of that but oh well. you got any pics as of yet? and there will be a difference even though he is going to be using a 96 IM becasue the engine is different. cant wait to see the # cause i never got around to doing that. what do you have left to finish?

 

I have read things from nissan when the engine came out and heard many times that 50% of the internals were changed.

But as far as wanting a 00 VI i have mine for sale it comes with everything to put the VI on ,even the 4th gen sensors on the IM.
The thing you will need though is a pathy TB. More info in 4th gen FS.

 

i am done transfering everything onto the DE-K engine and i have the transmission bolted to the motor. it is ready to be put in i just have to wait till friday to do it because i have off work. i am doing it at my shop so its been a cakewalk so far. also i dropped the engine and tranny out thru the bottom because it looked like the easiest way to do it. i dont know if thats the way everyone has done it.


by the way i dont have any pics because i dont know haw to post them. however if someone wants to give me their home mailing address i will be happy to mail you some pics if you will post them for me.

 

pkaiser@gmail.com, ill host them

 

i can host them for you. send them to vsamoylov@yahoo.com.

yeah i dropped the engine the same wya. through the bottom and put it on a skateboard and rolled it out of there.
