3.5
Ok I know that a 3.5 is better then a 3.0, but does it really make that much of a differance? 
Is it a direct fit?
Where could you get one, if it is that big of a deal?
Does the stock 3.o tranny, accessories, radiator, and all that good stuff fit?
Thanks in advance

get ready for some flaming.
yes and no, it fits, but some modifications will have to be made for it to WORK.
junkyard, or www.car-part.com
yes, all the accessories fit.
we have an all motor forum for this kind of stuff, dont post until you look around in there, or search first.

you need to take a trip to the all motor section, all the information is sticked in there. . .
but in short. . .
3.5 makes more power than the 3.0
Direct fit (in terms of motor mounts)
stock tranny will bolt up (MT. . . AT I dont know nor do I think so)
radiator will be fine
accessories should be fine also.
if your MT, clutch upgrade will be needed.
You can buy a pre-prepped engine from tilley if you dont want to have to deal with swapping sensors, etc. You'd just have to wire up the injectors, and a few other minor things and you're ready to go (after clutch upgrade).

Over a full second quicker and over 10 MPH faster on the trap speed... on the same wheels and tires.
Stock;
1/4: 15.00
MPH: 92
VQ35 H/I/E;
1/4: 13.68
MPH: 105
Sawblades and all-seasons on both runs.

According to an article I've read the 3.5 is 35 pounds lighter than the 3.0. Me and my bro picked it up with no oil or accessories on it. Never actually weighted it but from what I've read 3.0 is in the mid-200 area while the 3.5 is in the low 200 area.

The 3.5 is quite the powerplant. I drive my 98 Max 5-speed every day and think it is pretty fast.... until I drive my wife's 02 altima 3.5 5-speed.
Holy **** that car is fast.(0-60 in 5.9 sec) My Max can not even keep up (0-60 about 7.0 sec). The altima will run circles around it. The altima pulls like crazy (at any RPM), and gets 30 mpg on the highway and 24-25 in the city. No freakin comparison. 3.5 rules. I still love my 98 Max. She is my baby (175,000 miles, you can't even tell she is running at idle, plus gets 30 mpg highway). The moral of the story is the 3.5L is a beast.
There is my $0.02.

I have a DEK the way to my house with ONLY 8,557 miles on it. Will be going on soon. New alternator, Shorty SS Autochrome Headers, 6 puck Centerforce Clutch, Motor Mounts.

I've pulled 450 miles on a 70/30 highway tank with the 3.5 and no cruise control. Not sure how much more I could have pulled but I just filled it up and ran it until the needle was on Empty. So I wasn't running on vapor.

I read the swap info in the all motor forum. Still sounds as if they need to work the bugs out. This is in regards to the ECU, Timing, and the fuel return. I hope someone will work on a solution for these things. This basically means there is a lot more power to open up.

i think he means that over the years Nissan refined it to perfection then they switched to the 3.5 which is still raw.....interm terms of the little things that add up like usuable power....idle issues....stupid failures that shouldbnt happend that got worked out.....smoothness of revs

True, and to each his own. I decided on the DE-K based on the ease of the swap and that the only hurdle to it is the FI harness. Everything else pretty much bolts on. Then get a harlan switch or get a TS/JWT ecu.
On the VQ35 swap, there's way more work involved, mainly harness/wiring related, and getting the 4th gen ignition component to work in the VQ35.

Back to the question...you should really check out the allmotors fourm...there's a sticky there engine and all that you can get from car-parts.com. It's lots of work but in the end it's worth it.

The 3.5 swap doesn't have lots more wiring, its a bit more difficult, but you still have to solder new injector harnesses on just like a dek swap

Thanks for clarifying. After reading the 3.5 swap faq, I realized that its just way too much work for me IMO. Modding the fuel system, cams, tb, etc.
