Emanage Ultimate. Maybe a VAFC, but I'm not too familiar with those.

 

Cool thanks

 

im hittin the track on sunday. i was there at the same time last year and i ran a 15.3 hopefully i hit 14s with the VI

 

Hello, this seems to be the correct thread to post in, seeing as people in here seem to be knowledgeable about the 00vi swap. A few years ago, i did the complete 2000 DE-K motor swap. My car runs great, no check engine lights or anything. However when i did the swap, i never added the adjustable FPR on the fuel rail, im wondering if this could be my problem? My problem is that in cold temperatures, basically anything below 40 degrees Fahrenheit the car, starts, cranks over, catches but will not stay running unless i give it gas for 3-5 seconds and this only needs to be done once for the first time being started for the whole day. The car never stalls while driving nor is this issue ever replicated throughout the rest of the day. I'm thinking its either the FPR or possibly maybe something to do with the IACV / IACV adapter plate.At the time i did this swap, the 4th gen IACV was the best route to go, so if things have changed and there is an alternate/better route to go and some one can shed some light on it that would be great. If anyone has any information on how to fix this i would be greatly appreciated.

Thanks

It's probably your IACV. The symptoms of a bad FPR are inconsistent throttle response and even some backfires. That was the case with my car and it is still completely stock. The functions of the IACV and FPR will (or should) be the same whether you have an 00VI or not.

 

Thank you for your response, i want to say it's the location of the IACV along with the length of the hose. What size fitting do people use for their IACV adapter plate ? I have the adapter plate madeby stephenmax, i want to say that it uses a 3/8" barb which may be too small to support the proper amount of airflow.

 

I'd bump that up to 1/2"

 

I am currently gathering my parts for the 00vi swap. I have the im, lim, fuel rail, clips, valve cover & rear coils coming this week. not sure what tb I wanna do). I will be getting a vafc to take care of the tuning & rpm setup.

I have one question, besides the adapter plate (IACV), egr blockoff, is their any other plate or fab I need to do to the parts?

There is alot of info on the forum. Just want this to be painless as possible.

 

any updates?

 

I believe a.bop for the throttle body coolant path as well and you'll be set

 

Ok I have searched for info on this subject and have found advantages/disadvantages all over the place and power output, etc... but I have a question as to what exactly is variable. I know the runners are but are the length or width variable? Plenums? Valves? I may have overlooked it somewhere as there is a lot of info to look at but I figure it cant hurt to ask.

 

The 00VI varies the length of the intake runners, that's all. It changes shape to act like a long runner during low RPMs, then becomes a short runner at high RPMs.

The 00VI big advantage is that it gains everywhere, down low and up top.

Disadvantage is only one: it's a complicated install.

MEVI is way easier to install, but it is a compromise design: the MEVI transfers the midrange torque to the top end.

00VI improves mid-range AND top end over stock.

 

So for this I gotta have the 5th gen throttle body? Or can I use the 4th gen one??

5th gen lim
5th gen uim
5th gen valve cover
5th gen coils
4th gen fuel rail
4th gen injectors

So far thats what I have, I still need block off plates.

 

dude seriously???? you cant use 4th gen rails and injectors for the 5th gen lim. if you dont want to tune you have to flip your 4th gen lim 180 and do some modifications so it can bolt together with the 5th gen uim. even then your going to be iirc 1/16th off alignment of the two which you could grind down off of the vehicle. check out the thread your posting on......idk maybe read it

 

I don't have a complete setup yet but I'm gathering parts. So far im thinking 4th gen lower, 5th upper, tb, and iacv. But I have a quick question.

I'm wanting to run the 5th gen tb with the 5th gen iacv. I'm wondering what to do with all the plugs on the 4th gen iacv? I know ones for the egr and the brown one is for iacv. But what about the other two? They are red and purple. Will they have a place to go or will they be left hanging? Will they throw codes for not being plugged in?

I'm not opposed to running a 4th gen tb and iacv I just wanted the 5th gen for a cleaner look. Wanted to figure this out before I order the rest of my parts. Thanks!

 

Thanx for the input bro, I already got the 5th gen rails and injectors ;-) as far as throttle body ill get it too ;-) now I need to read and find out if I can just get all the egr plumbing ;-)

 

Just did a dek swap and have my 5th gen iacv hooked up. Works pretty good thus far. Question is I wired up vafc to control fuel. Have an adjustable for as well. But do I still need a rpm switch to activate the solenoid to close the butterflies in the uim? Or can I control that with my vafc

 

You can use the vafc to control the vias. I have not done the swap yet I'm still piecing it together. So i dont have an explanation on how to wire it up.

Any check engine lights running the 5th gen iacv? I'm trying to not use a remote mount 4th gen iacv to keep from cluttering up my engine bay. What did you do with the other plugs on the iacv such as the red and purple ones?

 

No codes. Just leave the other two plugs disconnected.

 

That's the route I will take thanks Schmelly. All I need now is an a33 throttle body and I'm set.

 

When using the 4th gen rear valve cover instead of using a 90' elbow for the pcv has anyone ever got a pcv that is made with a 90' elbow? I'm going to try to find one that works and ill post up the part number if I do.

 

yeah. Just wired up the connector for the 5th gen iacv and no codes. I started the 4th gen iacv and block off plate, but didn't have any problems with the 5th gen set set up. Leave those other two unplugged. And in regard of the vafc, I have it wired up, and have it set to 5k but it's jot working for me. Gonna buy a rpm switch anyways and c what happened.

 

If there were no problems with the 5th gen iacv why switch to the 4th gen?.. Sorry I can't help you with the vafc I have no experience with it yet.

 

I just wanted to c if jsutter idea worked and if worked better. My 5th gen idled fine then would idle high after warm. But was a vacuum leak. So b4 I figured that out thought it was a problem with 5th gen set up. So tried 4th gen. Works good too, just extra hoses and adapters. So just got rid of it. Works fine. But other people have issues. Have the adapters if u want them. Cost me about 70 bucks to make, u can have it for 35. Or I'll just return the fittings and get that back at least.lol. good luck

 

Set it at a lower rpm just to test it out, say 1500 or so. Then mess around with the vacuum lines going to the vias. I had issues getting my vias to work when I first installed the 00vi. I think what ended up working for me was running a vacuum line straight from the nipple beside the vias solenoid to one of the vacuum hose barbs coming off of the intake manifold.

 

I don't even have the vias solenoid connector hooked up. The vafc is on and working. But not sure how to hook up the connector on the solenoid. Maybe u could tell me or a pic of how it's is ran. Found no thread on this. So having a bit of trouble

 

Update. Hooked up vafc to vias. Can see activating at 5k. Thanks. Now if I can fix this idle I can get this thing tuned

 

So what needs to be done to have the idle close to stock?

 

I saw you got it working, but I'm going to post the link anyways. There is info in this thread: http://forums.maxima.org/all-motor/5...1999-se-l.html

 

I just got my swap done and it's untuned. Am I supposed to be running rich? My wb only shows that it runs rich like 10:1 with a nice smooth, albeit high idle only when my MAF is not connected. I found out I couldnt rev past 2.7k or so, I was like, "I forgot to connect the darn Maf" lol so then I turned it off, connected the maf and started it up again, and it idles pretty rough with about 18:1 afr. Also with maf not connected, it idles smooth, but high something like 1.4k rpm or so. I already tried adjusting my 4th gen TPS using the feel gauge method and I got continuity at 0.012" and no continuity at 0.016"...so what's the problem. I blocked off the egr and deleted the vias btw. But I don't know if that's why I'm running so lean/rough. Is the maf toast?

 

if the maf was toast you wouldn't be able to rev passed ~2.5k rpm also. iacv? i had a rough idle for like 4000 miles because i hadn't hooked up the iacv

 

Is the walbro fuel pump the one specced out for NOS, SC or turbo applications?

 

carsnwomen91, thanks for your reply man.
I have the 4th gen IACV. I also have 5th gen everything else..
I just cleaned my maf and it still didnt fix the problem. However, I notice quite a loud hissing from around the intake manifold, is that normal for when at idle with gutted 00vi?

Not quite sure that I follow you...but thanks.
Anyone have any tips here because its pretty annoying that I could drive my car if this problem is fixed. I did reuse all the IM gaskets from the junkyard that came with the 00vi. I notice that some places sell a throttle body gasket, and mine only has a skimpy looking rubber band gasket, nothing else, so is that complete or am I missing a throttle body gasket?

 

Whats the model number of your walbro fuel pump?

 

I don't have one, why are you asking me this? Unless the oem is walbro.

 

Doh! my bad..I thought when u said wb you meant walbro, but now I see you meant wideband........nevermind.

 

Doh! That's cool man. But do you have any ideas about my situation though?
Nm, I got it werkin. I forgot to attach the alternator circuit so the car was basically running off the battery. I got a 550-600 rpm idle with a 14.7 afr. This was pretty frustrating. I need to tune I suppose.

 

Got my 00vi on and she runs good. Doesnt like to idle when cold but idles fine when warmed up. Decided to go with all 5th gen except for coils and valve cover. I'm tuning it this Friday with a vafc. Can't wait!

Anyways I cannot decide on a good spot to place the evap solonoid and canister... Where does everyone have theirs mounted? I could easily mount it to the top of the manifold but that will prevent me from ever using a strut bar...

 

I bolted mine to the top on the im, I will see if the strut tower bar will fit and post a pic or two.

 

If you have OEM 4th gen injectors then you should expect the mixture to be slightly rich. That's by design from factory.

If you have 5th gen injectors then you should be running really rich. The 5th gen injectors are more powerful (potentially) so the 4th gen ECU doesn't deal with them perfectly.....hence the really rich results.
