DE-K swap threads
Hey guys, I have tried searching for some DE-K swap threads on here and through yahoo and all i've ended up with are some broken links. I'm looking for some general info on the swap and if possible, a detailed how to. I've never done a swap so I need as much info as I can get. If someone can please be kind enough to post some links or help out in anyway, I'd really appreciate it.

Unfortunatley I can't think of where write-ups are off the top of my head but swapping in a DE-K isn't the most efficient choice. It'd be better for you to swap over their Intake Manifold (00VI) since it's a variable intake it gives the vq30 much needed power at the top end. The only reason to swap in a DE-K would be if it were a much lower mileage engine.
Essentially the VQ30DE and the DE-K are the same, so swapping one in would just be like the same swapping procedure as it would be to swap in a VQ30DE.
Although, if you are looking to do an engine swap and have the money I'd recommend a VQ35DE swap. Much more power since it's a 3.5 and a better perfomance choice.
Also a lot of the links are broken and the mods know, but they have a lot of stuff that they have to attend to. So be patient because the links should be getting fixed.

i got a dek in, things like the EGR, runnin vaccum lines, different injector clips, then for idle you can use ivac off the 4th gen or mod the plug to work on the 5th gen ivac which is electronic not manual. If you need i have the block off plates and ivac relocation plate for 4th gen ivac use. Cold starts and low idle but the engine is great.

if you have a de-k engine just do the swap, its not hard and there is much more different internally than just the intake manifold. buying a used de-k compared to an 00vi setup isnt much different in cost for parts. there are write ups in the all motor forums.

no....its a little more complicated, you need to know about the coils, fuel rail, fuel injectors, rpm switch, egr, iacv, throttle body, other stuff (cant think of it all now) but its not just a simple swap of the intake manifolds. do some research in the stickies and all motor forum. its not too hard with all the right parts but its definately not as easy as you quote.

This is what I was thinking. I've heard some horror stories about 00VI swaps and unless you know how to do it yourself, I've heard of some ridiculous labour charges. Seems more practical to source a low milage DE-K and just swap the whole damn motor out. I'm hearing about VQ35s going for pretty much these days so I would assume a DE-K would be quite reasonable. And now, thanks to Dandymax, it almost makes you want to get a DE-K.

ok this thread is filled with stuff I just wanted to set straight.
First, an 00vi is from a 2000 or 2001. These are the years of the DE-K engine. You can not swap in just an upper and lower IM from a 00-01. You need to do a lot more work. Horrer stories? I don't know about that. I guess it can count since a lot of new guys think its easy to do, buy parts then realize they dont know what the f*ck they are doing and their cars do not work and they come here to people that don't want to help 24/7 because it was written for people in the first place.
On the engine...DE-K is a different engine then the VQ3.0 in the 4th gen. It is somewhat similar but has different stuff (i don't feel like getting into it) that make it better (IMO). The DE-k puts out over 200bhp so swapping it in will give power to your car. Doing an 00vi swap on the VQ3.0 is less work then the engine swap but still is a lot of work. Both require customization, work, and know-how. If you don't know what you're doing swapping them in, you won't be able to fix them when problems arise. The 3.5 obviously puts out much more power and is great in the 4th gen because its light and the 3.5 is a beast on torque. You can choose which engine you would want to swap because the 3.5 is a tough swap. Engines can be found all over so price can range. I have a guy selling a de-k for $375 with 70K on it. I really want it but don't have time to swap it.
Point is that there is a lot to the question and you need to do the work to find the information on it all. Start looking.

The DE-K is no different internally in ways that would matter performance or reliability-wise. The main internal difference is slightly larger main bearing clearance for slightly less NVH. The cams are indeed different as well, but all else being equal a DE with 00VI has better top-end power potential than a DE-K due to the DE intake cams having 8 degrees more duration (later intake valve closing).

Fastest and quickest n/a 3.0L-equipped maxima - DE with 00VI
Highest n/a 3.0 dyno w/stock cams - DE with 00VI
A DE-K with DE intake cams would be the best setup overall as far as not having to rig anything up to get the 00VI to work is concerned (plus the fact that DE-K exhaust cams have slightly more lift), but tearing into the motor just to replace intake cams wouldn't be worth it for some.

Wow, you guys dissapoint me. So much Nonsense and Crap while trying to answer such an easy question. Here OP is the answer you Seek.
http://tatanko.boredmder.com/
That is the Only Link You Need For Setting Up An 00vi Swap. Unless you really wanted pictures of.. Oh that bolt goes here and that one there.. Its all Very Strgight Forward.

Also, Tatanko's site is for 00VI swaps, not DE-K swaps.

So did you get the NATS equipment aalong with the ECU/harness/engine? THe same key as well?
Sure you wired up the NATS system properly?
If the key/NATS/ECU came from different cars, you need to tow your car to a Nissan dealer to have them reprogram the system.

man you should of done your research.
but like everyone else said ckps cps ground. I would suspect the ground up by the lower before anything though. especially if you have it grounded on the upper. also does the cel light come on when the key is in the on postion(not running) or im not sure that would even happen since you are running 01 ecu

I had a similar problem at first, and it was the ground. On the DE it goes to the LIM as stated, but there's not a similar mounting location on the DE-K. In order to get a good ground I ended up bolting the ground to the front valve cover, and then using a wire to ground the valve cover to the block. I know it should have got a ground off the valve cover, but it didn't, or it wasn't a good enough ground. After that it fired right up.
When you turn the key on do you get a buzzing noise from your relay box in front of the battery? Mine did.
