I could be speaking prematurely here since we haven't tried to fire up the car yet, but so far from what i can tell this swap seems a little easier than on the 4th gen. Here are some things i have learned so far.

1)PF tb does in fact bolt right up w/ the use of a adapter plate(do not need to mess with the IACV, its the same)
2) coil packs are pnp
3) injectors are pnp
4) VI plug on the 3.5l looks like it connects right up to the VI connector for the DEK
5) DEK fuel rail fits in the ports of the 3.5, tabs just dont line up

This isn't meant to bash on the 4th gen guys, just want to encourage some of you 5th gen guys to look into this since tilley is now making these cam adapters. Even though the 4th gen guys are lighter and can take more of a advantage of the power, this motor deff will add some nutts under the hood that the dek just can't provide.


PS just got done driving my moms 2005 g35 and omg that 3.5L puts the 3.0L to shame when it comes to driving on the street.

 

Coil packs are the same for us too.
I do agree though, more 00-01's should be doing the swap.

 

why not use the 3.5 throttle body and jus convert it?

 

Dunno his reason but my reason will be to retain cruise control.

 

to me it was just easier to bolt up adapter plate rather than ghetto rigging the 3.5 tb

 

You know why alot more 5th gens dont do the swap, Cause there newer cars. Your only talking a 5 - 6 year old car. People only really have 60-120K miles on these cars and are still breaking in. The 4th gen crew are working on a 8 - 9 year old car, and some over 200K miles. So alot of these 4th gen guys, its easier to swap in a 3.5 motor is easier than gettin a new car. Wait a few years and I think youll see alot more 5th gens swapping in 3.5's, plus by then they will be down in price.

cruise control ok? other than that its a 15min job that saves you atleast 100 bucks.but hey it all up to the person doin it in the end.

 

How

 

to a point i agree, but you have to admit when it comes down to people doing this swap it isn't always about people swapping in 3.5L just because there old motor has high mileage. It isn't economical to do ths swap on the 5th gen car since it would probably decrease the value of the car to certain potential buyers, but for the 5th gen guys who are looking for a fairly easy way to increase performance i can't see a better option.



I guess i have different view point being that my car is a salvage car(flooded) and i cant do a trade in.

 

Also people dont have have the time and resources to be doing the engine swap. Rememeber alot of these guys dont have the luxury of having a second vehicle like some of us and need their car every day to get back and forth to work and make money, No car, no money.

 

yep not having a car to drive for three months sucks (i am ready to kill myself)

thats why they need to get a gf that carts their a$$ around everywhere like me

 

Hopefully my swap wont take more than a weekend.
I just need to start saving the money.

 

Personally I think it sucks that 00-01 weight the same as a 02-03 , with the same body style and we got the lesser of the engine.

I didnt know this when I brought my Maxima because I really wasnt shopping around for a Maxima. I was shopping for a 240sx when a SE Black Maxima deal slap me in the face. I didnt even research NOR was I even going to plan to MOD it because I told myself with the New house . I should be spending money else where.... well after a few months and finding this web site. I decide to do (Light mod) which now im obessed to do more.

Altho I spent the last 10-12 years on Boosting my Altima , I had no knowledge of what the VQs can do.

Now I feel like Ive lost out because most 4th geners can do the 3.5L swap and still be faster than my 00.
And most 02's have the advantage.

I dont want to go thru dropping a motor and not having a car , even tho I still have the Altima as a Beater which I need to get it up and running ( non turbo anymore)
My Altima was alot more fun to drive being it was smaller, a fully built motor making 373hp . the Maxima is fast on the Highway when it comes to top end but its missing (turbo) low end power.. not only that Im stuck with a AUTO.

At this point I think I will hang up the Maxima and sell it because its not going to be anywhere near 4th geners (with a swap) nor faster than 02's or 04's...

Unless i drop another 3-4gs on boost.

Blah .. im done ranting.. good luck Chris and to the others

 

the only reason mine has taken so long was because of my whole cam ordeal and then waiting for my turn in the engine swap line

 

Does that mean you can use return style rails on the 3.5L? How are you going to hold them down if the tabs don't line up? Are the injectors of the DEK the same type and size as the 3.5L's?

allen

 

Injectors are same shape and size, psysically..

You can use the 3.5 rail as a return style.

 

If you use an adjustable FPR w/ a T in the line, right? I'm trying to get away from that mess if possible.

allen

 

1.take off the throttle body 2.drill the 4 rivets out 3.take off cover 4.unbolt throttle pulley. 5 swap pulleys from old tb to new tb 5. bolt down throttle pulley 6. put tps piece on and done. make a bracket which i have a template for.that just about it

 

i know what you mean. Once you put the injectors in the ports they are stuck in there pretty good. Now i am not going to say it is 100% full proof but i would just stick them in without bolting down the tabs if you don't have access to a welding machine.

PS allen i can sell you my old rail if you want. I already have the tabs cutt off so you can leave them off or re-weld them in the neccessary locations.

 

I'd be interested in them actually, can you send me a couple pics to turbosforsale@hotmail.com

thanks
allen

 

I just bolted on a DE-K FPR to the back end of the rail.

 

sure will++++

 

To the back end of a VQ35DE returnless rail? How's the fuel get in then?

I'm confused.

allen

 

basically its just like the 3.0 fuel rail but there is a damper instead of a fuel line.IIRC

 

+1

I just wanna know that my car will run fine with the feed line T'd off and putting an FPR on it. Seems pretty easy.

I have an SX7R line adapter on the front part of the rail. The rear part of the rail is a DE-K FPR.

Imagine what Kevlo posted above, but instead of that damper, I replaced it with the line adapter. You can sort of see it in this pic:

 

 

Ok, thanks. That post appears to show two options:

Option 1. Use an aftermarket FPR (adjustable or fixed for 51psi) w/ a T in the feed line.

Option 2. Bolt a stock type FPR to one side of the stock 3.5L fuel rail leaving it's stock feed line attached to the other side.

Then there seems to be:
Option 3. Switch the 3.5L fuel rail over to a DEK (00-01) fuel rail which is the old style return set up with one inlet and one outlet, accepts all VQ top feed injectors but doesn't bolt down without welding/brazing on new mounting tabs.


I'm using Option 1. but don't like the mess of fuel lines and the dorky looking chrome off brand adjustable FPR. So, I'm switching to either Option 2 or 3 depending on further research.



Chris'smax - Sorry to hijack your thread man!

allen

 

Option 2 would be the easiest, but option 3 would be better for fuel atomization.

For option 2 though, you would be better off with the SX7R fitting instead of the stock feed line.


Ok back on topic!

 

Gotcha, so that's like Option 2.5. All you did different then Option 2 was replace the 3.5L's feed line/damper w/ that line adapter. But, why replace it? Nice and clean though, I like it.

allen

 

There is no way I would ever swap a 3.5 into a 5th gen.

Why?

Because I would sell the 5th and buy a 5.5 gen.

I believe that's why you don't see more swaps.

 

That's another option, but not the most cost effective. People could say they would never swap a 3.5 into a 4th gen, and just buy a 5.5 gen. What's the fun in that?

 

True

But the fourth gen never came with a 3.5 from the factory. That was my point.

 

well that is just you.
