I got a question for all of you that happend to get the Cali-Spec version w/ the Swirl Valves installed on the 5th gen LOWER IM, how did you plug these holes???

 

Can you take some open/closed pics of the swirl valves???

 

Yeah it took a couple trys to get it all working properly but I just fixed it finally. It idles about 600-700 with out it jumping all over the place. It's kind of a combination of throttle body and iacv, the iacv controls it in the morning with the cold starts and throttle body stops it from falling below 500 rpms. I had trouble with it dipping all the way down to 100 and some times it just would die on me. But I have it all working properly now

 

Mines idles at 1,500 rpms on cold starts and gradually goes down until it gets warm. Works as if I am still using my 4th gen iacv. And let me know if you need any help this weekend I could come down if I don't go out of town this weekend.

 

This is splended!!

So 5th GEN TB with adaptor plate to block off 5th GEN IACV. 4th GEN IACV. 5th EGR guide tube using 4th GEN EGR. Me likes, so I can finally start on this as soon as I have a bit of cash to buy the adaptor plates.

 

I already broke them off :\ sorry...

I dont get the point of them anyways, when there closed they cover up the entire hole, except for a small about an inch big square to allow air through.. :\

 

I thought I said that?

Apparently not huh?

Ok, so lemme try this again. The 5th gen IACV ends up being in the way of the 4th gen EGR when u swap the 5th gen tb onto the 4th gen upper im right? This problem doesn't occur when the 5th gen tb is being used on the 5th gen upper manifold b/cuz the 5th gen has a diff. EGR system so there is no EGR stuff to get in the way of the IACV on the 5th gen tb right?
So basically these adapter plates are jus for relocating the IACV on the 5th gen tb so it's out of the way when u put the 5th gen tb onto the 4th gen upper manifold right? Pleeeaaze tell me that's right!
The only difference I can see in what u said is the addition of having to block off the 5th gen IACV ports on the tb if you want to use that tb w/ the stock 4th EGR. That right?

The only other part I'm not understanding is this:

Why would you run into a problem using the A32 or Pathfinder tb and IACV? You mean cuz ur using them on a A33 upper im, which has a diff. IACV design than the A32 upper?
I greatly appreciate your patience with helping the newb understand the complexities of custom retrofits!

 

What exactly is it about the A33 upper or tb that makes it necessary to mount the A32 IACV on a plate and run an air supply hose from the back of the plate to the A33 intake manifold?

 

The A32 IACV mounts onto the backside of the A32 intake manifold. The 00VI has no such mounting provisions. Therefore if you want to retain the use of your A32 IACV, you have to mount it remotely and run an air supply hose to the 00VI.

It sounds like some people have successfully converted to the A33 IACV by moving the egr stuff underneath the throttle body and by changing the IACV harness connectors.

 

So since I wanna retain the A32 EGR and use the A33 tb, would I jus have to remove the IACV from the bottom of the A33 tb and block off the A33 IACV ports so there are no leaks? But then how would I control the idle? I want it to function as close to the stock 4th and 5th gen IACV as possible. How does everyone w/ the A33 tb control their idle?

 

Wow...you've really confused yourself man

I'll give a shot at clarifying things for you.

In case you don't know A32=4th gen, A33=5th gen.

You need to understand that the A32 TB does not fit the A33 IM and vice versa. So you cannot "swap the 5th gen tb onto the 4th gen upper im," so that is NOT what is being said.

You have a number of options when doing this swap...none of which uses the A33 EGR (you must either use A32 EGR or don't use any EGR).

Option 1) Use an A32 TB (using an adapter plate between the TB and IM) and the A32 IACV remote mounted using an adapter plate and running a hose into the IM. Using this option can can either use the A32 EGR with the A33 EGR guide tube, or use no EGR at all.

Option 2) Use an A33 TB mounted directly to the A33 IM and remove the A33 IACV which is mounted to the bottom of the TB and cover the hole with an adapter plate, and use an A32 IACV as above. Using this option can can either use the A32 EGR with the A33 EGR guide tube, or use no EGR at all.

Option 3) Use an A33 TB mounted directly to the A33 IM and leave the A33 IACV and rewire your wiring harness to plug into it (this option will not really allow you to adjust the idle...your at whatever the ECU decides). Using this option you would have to relocate the A32 EGR (probably not worth the trouble) or eliminate it.

That make sense?

 

You remote mount the 4th gen IACV and control the idle as you normally would.

 

Nm, I think I may have figured it out. This is where I'd have to mount the A33 IACV onto a plate and run an air supply hose from the back of the plate to the A33 intake manifold right?

 

You mount the A32 IACV onto a plate and run an air supply hose from the back of the plate to the A33 intake manifold

 

not true all you have to do is adjust the A33 throttle body so you can control the idle. And to make room for the A33 IACV you need to take the EGRC-BPT Valve (looks like a UFO) and take it off its bracket and move the bracket holding the group of metal tubes and there should be enough room. Or at least that is what I did.

 

That part I knew. A32=4th gen=95-99 model years. A33=5 & 5.5 gen=00-03 model years.

That part I didn't.

This is the option I'm interested in since I wanna use the already existing A33 tb. So how do you control the idle w/ this setup? Does the ECU control it still?

For the most part yes. Thanx.

 

I think the best route is using the A33 TB, and using the 4th gen IACV, mounted remotely. This would eliminate the need for the TB adapter. Relocating the IACV should be alot easier than relocating the EGR.

 

Oooohhh...This is done because you can't use the A33 IACV w/ the A32 EGR (w/out re-routing a lot of EGR stuff which I don't wanna do) so you "remote mount" the A32 IACV onto the A33 tb w/ a plate, cover up the A33 IACV ports to avoid leaks and run an air supply hose from the back of the plate to the A33 intake manifold. Right or no?

 

I agree, I fabricated a plate to block off the IACV on the A33 TB, so I can use the 4th gen IACV with a plate.

I havn't tested it yet but I cut it out of a sheet of aluminum...




The IACV plate I plan to purchase off someone, I dont think i'll be able to make that one.

 

You make a plate for the 4th gen IACV to mount on, attach a barb fitting to it, and attach another barb fitting anywhere on the manifold after the TB, then you connect a hose (large diameter, or idle probs will occur) In a sense, you can mount the IACV anywhere in the engine bay.

 

You control it using the 4th gen IACV as you normally would.

 

So since I want to retain my A32 EGR, my best bet is to use the A33 tb w/ a remote mounted A32 IACV right!?! Like Nismo said, I bet it's much easier to relocate the A32 IACV onto the A33 tb and block off the A33 IACV ports, than it is to relocate the 4th gen EGR stuff and use the A33 IACV. Do I get it now?

 

Partially. You're not gonna mount the A32 IACV onto the A33 TB. You can mount it anywhere else though.

 

Yes essentially. You don't mount the IACV to the TB necessarily...I'm not sure if there'd be enough room. With remote mounting it you could pretty much mount it anywhere.

 

Yes... I think so... lol you have confused us all...

Fab plate to block off IACV opening on A33 TB.

Make/Buy Plate for A32 IACV and attach a fitting to it, grab air from intake -> A33 manifold.

Mount where you please as long as the connectors reach.

 

Sorry for my ignorance but how is that? I never had to adjust my idle.

 

Just hook it up like you normally would, you dont have to adjust it as far as I know.

 

So where do u guys typically mount it? Where are the stock A32 and A33 IACVs mounted?

 

The A32 IACV is mounted on the A32 Intake Manifold, The A33 has no opening for it, so nissan mounted the A33 IACV on the A33 Throttle Body...

Once you FAB up a plate for the A32 IACV you can put it wherever you want.

 

Who, little ol me??? lol Sorry guys I'm on the learning curve ya know?
And when u say attach a fitting to A32 IACV it means just that, attach a fitting to the A32 IACV that normally sits right next to the A32 TPS on the tb right?

 

Yes correct, you attach a fitting to the plate (or if you buy one it might come w/ it already installed) then attach a hose that goes from that fitting to the A33 IM to feed it air.. and the other tube goes to your intake.

 

Here is one of StephenMax's images..

See the A32 IACV on teh right?(Ignore the TB Adapter you dont need that if you're using a A33 TB.)

 

Buy a haynes manual. You adjust it by turning the black plastic screw on top of the IACV.

You can also buy the plate for blocking off the A33 IACV from maxS (I expect stephen max could do it too)

 

Ok. So then my list for the DE-K VI retrofit onto my DE engine should read as follows?

1) 00 upper manifold and tb
2) a plate to block off A33 IACV ports on tb
3) a plate to mount A32 IACV onto
4) 00 lower manifold
5) 00 fuel rail, injectors and connectors and
6) Summit rpm switch

Am I missing anything major? Other than misc. pieces of vacuum hoses and elbow/barb connectors I can pick up at any auto store I mean.

 

I have one. Just can't find it at the moment. Thanx though.

 

Yup I see it thanx. That's real high quality work on the adapter don't u think!?

 

00 EGR guide tube...

 

What are you doing with the EGR again?

 

Right, forgot about that one!!! Thanks! Is that all?

 

Ummm...is this a test? Nothing because I plan on using it the way it is stock. Right?!? Oh ur asking cuz I left out the 00 EGR guide tube on my list right? lol Sorry bout that, I clean forgot about it.
