Well I'd rather have metal nipples that I know I secured. Just that I'd feel more comfortable having the metal nipples jb welded on there and know they won't break off like the plastic ones could. Plus I need to drill holes for mine anyway.

 

matty i dont know? you know me just trying to follow instructions, through most of this its been like watching the amazing race on tv, picture me going in the wrong direction, with map upside down, screaming I know what im doing, while everyone on tv is screaming turn around dude your going the bloody wrong way !

to me though, example one seems to best example how to cut that part off, and then drill/tap it.

and do we use the same technique on the EVAP nipple.

 

hold up ! is that the only reason we are doing this ? because some people would prefer metal over plastic ? i thought it was because the nipples were to small ?

 

OO damn. The diameter of the plastic nipples are too small. The nipple on top of where the TB attaches to the UIM need to be 3/8" so you can connect one of the EGR/EVAP hoses. I forget which one it is. That the one on the side usually is the bypass hose for your IACV. In this case you will definitely need a nipple that is fairly large.

OO by the way I'm using a plastic 3/8" elbow for the top nipple 10,000 miles and going strong.

edit: Cut it in example 1

 

It's 1/2 nipple for the back one right? For the IACV I mean.

 

I don't know. I'm using the 00IACV.

 

speed racer, how you using the 00 IACV? w/ the 4th gen plug? does it still function normally?

 

from what i understand that is correct. pat was saying its the same size as the nipple in stephenmax's IACV adapter plate he makes.

 

Thanks Ceasar. I'm glad you posted this btw. I'm about to do my swap and it's really helping me out. Progress is looking good too.

 

cool, i start back in a few days on mine. just trying to get everything done right the first time. Moving on to phase two now. Find more information by clicking link below.

My 00VI Project: For Vacuum Hose and troubleshooting: Part 2: http://forums.maxima.org/showthread.php?t=502605

 

Yeah I like this thread because it's helping me make sure things will go right the first time.

 

Do not plug vacuum to the VIAS left port, unnecessary. Reason being is when you provide vacuum sure as soon as you start the motor it will open the VIAS fully, but when you start to give it gas and/or go WOT there will be no vacuum in the manifold aka the flap will close again. You wont need vacuum even after you add the RPM switch/VAFCII into the equation because of the already mentioned scenario. Just leave them open or plug them up.

I used #2 as vacuum for my EVAP canister, which on a 95 FED its in the engine bay. The fitting is perfect, although on a newer style EVAP I used #3 with a larger metal fitting tapped in place and plugged it there.

 

So leave the the two VIAS plugs open or what?! I'm confused with that post.

 

yes, open.. my RPM switch wouldnt activate the VIAS with vacuum supplied, as soon as I removed vacuum presto..

 

Hmm ok. Pat do you have them unhooked as well?

 

mine does w/ line running to midpipe

 

I suppose that could work.

 

Well it seems inbetween on the hoses or not. Some seem to have the left nipple to the midpipe and some don't. Guess that'll just depend on my car.

 

I was just thinking about these hoses again. I wanted to tell my plan to you experts and see if I would be ok. Ok so the nipples from left to right are 1-5. #1 is brake booster, #2 I was going to drill a 3/8 nipple for the PCV. #3 was going to be left as is and I'll be using that nipple to t all the small hoses off. #4 will be replaced with new 3/8 nipple for EVAP, and #5 will be a replace 1/2 nipple for IACV. Is that going to be ok? How many little hoses need to be t'd off? I was looking at the pics but I'm not sure.

 

Hey I also need to know something else.

This is the TB I have. It seems to be different then what other guys are using. I think it should work the same tho. Are the tubes on the bottom for coolant?
All the way on the left behind the bracket is the bolt the holds the CC and Throttle brackets on. The tip of the bolt seems to be hitting the back of the buuble on the VIAS.

This picture shows the block and the VIAS. You can see the bubble I'm talking about.

My questions is, I'm going to trim that bolt down and I was thinking of shaving the bubble fromt the VIAS. Is that ok? I'm not sure how thick it is. I'm only talking about an 1/8 or so of shaving so the bolt holes can line up for the TB and block. Any help would be great.

 

Anybody know?

 

If your using the 4th gen IACV than you need to make a block off plate for the 5th gen TB. This would mean your coolant lines will be by-passed.

Try to cut the bolt a little shorter. I wouldn't try shaving too much off that bubble valve. It might not be functional if you mess it up.

Also, on the UIM... there seems to be a hose missing or closed shut. If its closed shut, than your going to have to tap into that. That is one of the major sources of vacuum for your hoses.

 

Well far left wil lbe brake booster. In the middle you can see where the spot was jb welded by krismax. I'm drilling that for a 3/8 nipple for the PCV. The nipple next to that will be used for an extra vacuum to t off all my smaller hoses. Next to the block will be redrilled for a 3/8 nipple for EVAP and then there is a brass nipple under the block I was going to use for IACV. Other than fitment issues the TB should work right? I will be using 4th IACV and TPS. Not sure I can make a block off plate. I was planning on just running those coolant lines anyways. If they have a spot on there why not? What do you think?

 

I don't know if that's possible to run the coolant lines through there and still not have a vacuum leak. I would recommend a block off plate. You can just get sheet metal to cut. You will have fitment issues if you keep the IACV under the TB. This would mean that you will have to remove the vacuum gallery underneath and unbolt the egr valve.

 

I thought T'ing off the hoses meant getting rid of the vacuum gallery? The IACV connects to the back of the block so I wouldnt keep on there anyways. How thick should the sheet metal be? Just the sheet metal and sealant will be ok to block it off?

 

Yea, T'ing off the hoses means getting rid of the vacuum gallery.

I don't know how thick it is, but its the one you can cut with special scissors, but I don't know how it will hold. I'm just trying to give you a cheap solution instead of buying the usual 1/8" aluminum sheet and than cutting it.

 

Yeah I appreciate it speed. I'll try to find some sheet metal. Maybe something a little thicker. I have tools to cut it so that won't be a problem. That and the sealant should be ok. Other than that the TB shouldnt have a problem right?

 

nope I think your set.

 

Sounds good. I'll work on fitting this weekend.

 

I forgot to ask before. I know a hose is supposed to run to the bottom of the TB. Which hose exactly is it? I have a nipple under the block but I wasnt sure what hose went to it. I'm wondering this if I have to put a nipple in my block off plate on the tb. Thoughts?

 

Jsut wanted to bump my last question and say that I did trim the bolt on the TB. It fits good. Just trying to get the bottom plate off now...

 

Can someone please sticky this thread? I just got my 00vi today and it is helping me tremendously.

Thanks

 

I have a '99. If I were to use basically all '00 parts, could I just snag an '00 ECU to run it all with as well?

 

What would be the benefit of this? It can be done, but it's more trouble than it's worth. pin by pin, get everyone talking the same language

 

I figured they would run the same harnesses...and you'd just have to wire the IM switch

 

different harness. Not worth the trouble of a $40-50 rpm switch.

 

I just want to thank ceasar for making this thread, and everyone else who participated in it, in particular 97maximus, gtr rider and speed racer. I finally got around to doing this over the weekend, and with the info in this thread, and other threads that I dug up through the search, I got it running without having to ask a single question. No codes or cold start problems either. To any DIY person who may be considering this but having second thoughts, just go ahead, take your time, and do it, trust me!

 

I need help with a dek engine swap not the 00vi swap, please any assistance will be deeply appreciated
