Sweet so u are on this board..i just replied to your other message...
I have a few questions...
what would u have needed to do to get rid of your CEL's??
I guess i have been reading about the vtech and still not quite sure what or how it works.. or what u would have done different to be honest..

well i think i've got my money saved up, i'm looking at a 3.5 for $700 with engine harness, now i think i need dash harness, its going into a 00 auto, i've been quoted 12-15k in labor so about 25k should do me good??? or there's more parts needed???

For $12k, you can pretty much BUY a Maxima with a 3.5.

this writeup was amazing, im actually using the 1st half of it to pull my engine to rebuild it. though im considering just going through with the swap instead. but i have a question first

WHY do you have to swap the timing components from the vq30 into the vq35?
someone please PM me with an answer.

I'd rather post the answer hear, and maybe discuss my plan that is in the works.

In order to run the 3.0 ecu, you need the 3.0 cam sensors, which means 3.0 covers and cam sprockets.

Anyone have a link to some oscilliscope readings of a 3.0 cam sensor? I know I have seen them before, and I don't think the 3.5 ones are as hard to obtain so I can probably find them on my own.

I believe there are some 3.0 ones in one of the original EU threads by Dandymax

I thought it is pretty obvious he missed the decimal point.


1.2-1.5K in labor and about 2.5K total.

hehe Anyone want to do the swap for me? I am pretty lazy when it comes to projects like this at times.

I already have a complete 08 3.5 motor i aquired with 18k on it.

Amazing write up for starters.

But i had some questions. Maybe i missed it. But doesnt the VQ35DE have a VVT system not present in the VQ30. So swapping out the Timeing components and not using the VQ35DE ECU eleminates this VVT system correct?
Is there a write up out there for a complete swap. VQ35 Swap with motor/ECU/Tranny into a 4th gen. unless using the VQ30 ECU is the best way to do it. Im really trying to get this swap done. im ready to purchase motor. Im just having trouble finding a manual tranny (either VQ30 or VQ35). what do you suggest is the best tranny to use? Can i use the 350Z Tranny or is drivetrain difference an issue? i hope you guys can help.

and agian thank you for write up. I feel 90% smarter about the swap than before

ajcool2

iTrader: (43)

Yes you lose VVT with this swap. No there is not a writeup for the full swap including the ECU but theres enough info here to do the swap. Search ENG92's post. No you cant use a 350Z transmission since its rear wheel drive.

3Point5L

thats what i figured but i had hoped my noob mentality would be wrong, lol. I was checking out eng's posts as far as the ECU looked extremely dificult and seemed as if they were talking gibberish. Im going to disect it a bit more. Im just thinking about the loss of VVT system. Would the swap still be worth it without it? still a comparable gain from VQ30 to VQ35. and how much of a difference is it without the VVT system (VQ35 swap). extremely noticeable or is it like...ahh, a difference, buit no biggie, im still moving

pmohr

iTrader: (26)

Yes, you would lose CVTC. Yes, you still gain power even with a hybrid swap.

Most don't feel the difference because they choose one swap or the other, they don't change things up after a while (with an exception or two I can think of). It can be a substantial amount of power difference, depending on how you set up the cam adapters (assuming hybrid with VQ35 cams).

3Point5L

I think im going to just go for with the VQ35 swap and VQ30 components and ECU. there is a write-up for that exact swap that is extremely detailed, nicely put together. now my only issue is finding a damn manual tranny. Im going CRAZY OVER HERE!!! lol.

I just got mine done a few months back may be I can answer some of your questions...ask away ...

sergofast

iTrader: (22)

Would you mind elaborating on this? I am debating doing the full ECU/harness swap. Mainly because I have seen some pretty low HP figures compared to the 3.5 w/the ECU.

I already have a 2001 AE VLSD tranny so Im keeping that and I have the fidanza lightened flywheel and JWT ECU w RPM raised but I can always get it re-flashed if necessary. These things are what are making me lean toward the vq35/vq30 timing hybrid. (along with simplicity)

tommymax

I was wondering the same thing.

sergofast

iTrader: (22)

Crap...i thought you answered my question....is been up here for 3 days...doesnt anyone visit the all motor thread?

anyone?

Snowbiker

do you have to use a vq35de out of a maxima or can or can it be out of another vehicle that has a vq35de?

AWD engines (Murano) works too since it's also transverse-mounted.

excellent write up for sure!! question though, what oil pump will be used? the one from the 3.0? or the one from the 3.5? i'm assuming 3.0 since all the timing parts will be swapped over to the 3.5

Weimar Ben

iTrader: (5)

You use the 3.5 oil pump. It's not a timing component. You can also use the rev-up oil pump, which allegedly flows more.

phatboislim

iTrader: (27)

ok thanks for the info. i'm going to get all of my necessities, which isnt much seeing as though i have my de-k, then work on getting the goodies. want my car back on the road within 2 months, 1 month = better

Crusher103

iTrader: (10)

You have to use that ring(i forget what its called) off the 3.0s oil pump because the 3.5 timing chain is different from the 3.0 chain. The both of them should slide right off, they have been covered in oil their whole life so it should be that difficult to get off.

phatboislim

iTrader: (27)

i wont be doing much of the work although i will definitely lend a hand, unless you are wanting to do it for me with all the help i can and a few packs of beer and pizza and all sorts of junk food lol

It isn't mention in any of these stickied threads that there is tuning required. Am I missing something?

ajcool2

iTrader: (43)

Its pretty much a known fact that when using DEK or 3.5 injectors with our stock 3.0 ECU's you need to tune the car.

skweaky

iTrader: (3)

The write-ups for the 3.5 swaps do not include tuning devices in the parts list for a complete swap. No tunning info is included in any of the write-ups. There is in-depth coverage of every part of the build from timing changes to fuel pressure, but no mention of A/F tuning. I just think a full swap guide should at least mention that.

P.S. I love the guide posted here. I am not knocking it or saying that it is "incomplete". It is just that one step from being 100% encompassing.

ajcool2

iTrader: (43)

I think the purpose of the write up was to help get the engine in the car and running correctly. Tuning and other mods are not exactly required. There are other threads discussing how to tune after the swap if you decide to.

skweaky

iTrader: (3)

Mention of tuning be optimal for the swap is all I am asking for. I know it has to be tuned, but people use these guides as a pretty huge part of their swap process. It would be a great addition to put a small note somewhere about the A/F ratios with swap being pretty far out of spec.

But go ahead and post again if you really feel you need the last word. I am sure everyone here knows by now that you have the biggest "member" on the site.

ajcool2

iTrader: (43)

I simply responding to why tuning wasnt included in this swap. I hope anyone doing this swap wouldnt stop at this write-up and research how to get the full potential out of thier motor.

You could always contact the OP and ask him to add it since its such a big issue for you.

Crusher103

lulz, n00bs.

Relax, before you start thinking somebody is trying to get on you realize that he has done a couple of 3.5 swaps he knows what he is talking about, he is just trying to make sure you dont make any mistakes.

AFRs for all NA cars is pretty much the same VQ, low 13s is pretty much where you want it. High 12s if you want to be more on the safe side.
