I am looking into doing a swap and was wondering if it is worth it. First off is the 04-05 Intake a VI intake? I know ihave heard the 3.5 can be stufed into the older Maxima's if you use the 95-99 intake and do some adapters for the cam gears but can you put a 04-05 intake on a 95-99 3.0? If it would gain me some ponies and soem Fuel milage I may just do it. Chime in if you have done this swap. I have a partial 00vi setup but would go with the 04-05 if it is worth it.

 

is 02-03 intake same like 04 05??

 

I do not know. I have read up on the Mevi swap and the 00vi swap but have seen very little on a 02-03 3.5 swap for an intake.

 

i didnt see anythink about swapping 04 intake

 

its all about the upper manifold on 00-01 you want

 

So the 04-05 intakes are just a normal every day intake then nothing special about them.

 

I was pretty sure all VQ35 engines had a variable intake manifold. Either way, you wouldn't gain anything from attempting to use one over an 00VI, and you'd need the 3.5 heads in order to use it anyway, making it all the more of a headache for not much benefit.

 

3.5 IM is nothing special, it's a bit better than the regular 3.0 4th gen USIM, peak power is about 5600 and it drops off hard after 6200-6300 or so, while the 4th gen drop off is more around 6000, but the one you want is the 00 VI. It peaks around 6400 and doesn't really drop off until 7k. The "special" IM for the 3.5 is the 350z intake, which has an amazingly flat tq and power curve, but it doesn't fit FWD applications, unfortunately (can't close the hood).

 

so you saying that better si 00VI than "04VI"

 

I'm a bit confused on why you would have to use the 3.5 heads. I can stuff a 3.5 into a 95-99 by using the intake from the 3.0 and all the rest ofthe parts with it. There fore a 3.5 intake should fit the 3.0 with no major problems right? I guess there might be clearance problem or 2 but a grinder and tig welder can fix that problem.

 

For a 3.0L the 00-01 VI is the best possible option. Great mid range power, super flat TQ and HP curves, and excellent flow all the way to 7000 rpms.

 

How difficult is the swap to the '00vi? is this something a weekend hobbyist can do? or is this serious engine labor?

 

easy for a weekend hobbyist, its not too bad.

 

The 3.5 intake manifold will not bolt up to the 3.0 heads. The heads are different. Also, it hasn't been "proven" per se, but certain people believe the 3.5 heads flow better. I'm not saying that's fact, merely what some people believe to be true.

 

So if a the 3.5 heads are different how can you bolt a 3.0 intake to the 3.5? I have seen 2 with the 3.5 in them using a stock 3.0 intake.

 

That's because they're using the 3.0 heads.

 

I'm am sure all they did was use the spacer to set the cam gears off to get the proper alignment up for the chain. I am im them both now to see if that is correct but I know that's what they both said.

 

Why would anyone put a 3.0 intake on a 3.5 engine? Isn't that like buying too small of a condom?

 

Intresting thead.
So just so I am crystal clear, The 3.5 intake is NOT a VI, correct?

I would guess not. You can't beat cubic inches. HA!

 

Why would anyone put a 3.5 in 95-99 Maxima? Because they can and it's a sleeper if you don't know about it.

 

You would guess wrong. It is indeed a VI.
No, they're using the 3.0 heads because the intake manifolds don't line up, IIRC.

 

this is a great thread, very informative

question: what else would you need other than the 00vi to do the 00vi swap? I imagine you will at least need a new gasket, anything else? anybody? thanks!

is it worth it to do this swap? sounds like it is better than stock 4th gen intake

 

you will find more info in all motor forum

 

thanks for clarifying that for me.

Just out of curiosity, are there any good pics of the 3.5 IM on the org?

 

Yes there are ...

 

Any more comments on This?

 

What else is there to say?

 

owned.
now ---> of thread. lol jk
