2000 VI is now on and running on my 96
#282
Well looking at BOTH fsm's, it appears the terminals #1 and #2 are swapped and #4 and #6(tab connector at top) are swapped.
Resistance is 22-ohm on the 5th gen and 30-ohm on the 4th gen.
Verification for resistance between terminals is IDENTICAL though, so who knows.
You still need the other devices such as FICD that are part of the IACV assembly.

I figured all of this out because i will be putting electric power steering on this summer 5-7 hp everywhere
#284
What's FICD?
I thought you'd already done the electric P/S? Maybe the thread I read was just one where you were planning on doing it. I'm very interested in this as well because I've removed the P/S pump from my DE-k to further quicken installation so I may get tired of no P/S and want to do the electric pump.

On the 4th gen there's a fast idle control cam. Raises the idle based on the temp of the coolant. On the 5th gen one though, it looks like its controlled by vacuum. And another thing that I found strange is the coolant that flows through the 5th gen TB goes around the IACV, not any type of fast idle cam. The way they have it, it makes me wonder why they even route it through the TB at all.
#288
What do you mean? Are you talking about the coolant and the IACV on the 5th gen TB?
On the bottom of a 4th gen TB there is an inlet and outlet for coolant. People commonly bypass this for hopes of keeping the TB cooler and keeper intake temps down. Not proven to help though. Anyway, on a 4th gen the coolant flows in and around a piston that, when cold is pushed out, holding the throttle open a bit. As the coolant heats up, so does this piston or cam and it recesses back, thus allowing the idle to drop.
On the 5th gen however, the coolant flows in in much the same way, but there is nothing (that I can see) that would make a difference to idle whether the coolant is hot or cold. It just kinda flows through the middle of the IACV. There is a strange looking spring with flat coils (as opossed to round) that may do something with relation to the coolant temp but I'm not sure what.
It looks like the fast idle "cam" on a 5th gen is located at the top of the TB. It looks like a piston that is controlled by vacuum as it is connected to the throttle body behind the butterfly. IS this in fact the fast idle cam or am I off in left field?
What I wouldn't give to sit down with an actual Nissan designer/engineer and go over this engine. Man, that'd be cool.
Sorry if I told you a bunch of stuff you already knew. Just trying to expand on the my last post a bit.

#289
Not quite off topic, but I am having a very hard time with all of those vacuum/coolant/fuel hoses on my 4th gen. The 96 FSM is a little vague. Does anybody have any pictures of the hoses?
Kudos to BSwithTF, for telling me where to hook the coolant up to the TB.
Doing an engine swap for the first time, and like an idiot, i didnt mark anything except the fuel in/out.

Why not? Are the two sets of bolts in the way?
Also, any idea what it's going to cost for these?
I'm talking with a fabricator/machinest friend to see what he'd charge for these, but I have a feeling it's going to be too much for what people would pay.
Probably cheaper/simpler to go with a 5th gen throttle-body, so I may just have a couple of those made, if any.

ok i understand that now. the next thing that i got confused on was the bracket part? why do u need a special fabricated bracket to put a 4th gen throttle body on the VI?
and is there anyway to get rid of the low idle speed if i use a 5th gen throttle body?

I will set the price from $135-150 around $150 shipped.

If you don't use the 4th gen IACV, then you have to use some other means besides ecu control of the idle speed (yes, the ecu does control idle speed). The old school way to do this is by using the throttle body butterfly plate adjuster screw. This works pretty well for me, but there is a minor issue of the idle speed being a little low until the engine warms up.

Now you really should concern yourself with the stock valvetrain. The VQ35 retainers are the best option because they're lighter than titanium and only about $3 each from the dealer.
I have been waiting for a good opportunity to realease this information and this appears to be it. The VK45 titanium valves are near identical to the VQ30 valves. The only thing that is different is the total length which can be adjusted with new shims.
VQ30DE Steel valve;
Face In: 36.0 - 36.3mm
Face Ex: 31.2 - 31.5mm
Stem In: 5.965 - 5.980mm
Stem Ex: 5.945 - 5.960mm
Length In: 97.32 - 97.82mm
Length Ex: 94.85 - 95.35mm
Valve seat angle 45º15' - 45º45'
VK45 Titanium valve;
Face In: 36.0 - 36.3mm
Face Ex: 31.2 - 31.5mm
Stem In: 5.972 - 5.980mm
Stem Ex: 5.962 - 5.970mm
Length In: 96.57mm
Length Ex: 94.50mm
Valve seat angle 45º15' - 45º45'
The faces and the seat angles are identical. The stems are slightly different only because the expansion rates are slightly different between the metals. They're both classified as 6mm stems.
The only question that remains is the location of the keeper. If it's high enough on the Ti valve then there is no problem. If it's too low then custom retainers will be needed to make them work.

also i want the titanium valves did you find out if they are in the 56?

P.S if anyone wants one of those adapter blockes ill have a few there

You and 98Blackmaxse. I must hear this thing in person

yeah that is kinda what I figured, I just saw the words "bypassed the rev limiter" while skimming through and was wondering if this was done of if he got the JWT. I would watch those 8K revs though without some stiffer vlave springs.

how much modification is required to install a 5th gen tranny in a 4th gen ?

there is no modification needed. I currently have a 2k1 5 speed tranny in my 97 SE 5 speed. Some say that the shifter sits too low and effects driveability but it doesnt for me. Maybe cause i have a pascetter STS but looking at how it is, i dont think it causes that much issue. Mine sits almost perfectly in the middle. If you want to see a pic, PM me.
2k2+ tranny on the other hand is another story. And 2k+ auto's may take a lot of modification since they involve more computer stuff...

If i can get a good enough deal on VK45 valves I will inspect this. I can't use the VK intake valve in my VQ35 because the face is 1mm smaller but I can use the exhaust valve if I shave the stem to make it shorter. The reason behind that is the VK45 valves are longer than VQ35 valves but shorter then VQ30 valves.
The VK56 uses the same size valves as the VK45 even though it has a much larger bore of 98mm. If the VK56 used ti valves it would be better because I have better access to Nissan parts as opposed to Infiniti parts.
