Is Maxima v6 block same as 300zx?

First, don't call me names because that usually motivates me to do what is coming up next....

Second, you obviously didn't understand the part where I said "short answer", so I'm going to give you the LONG answer which will in turn show you why I was RIGHT in the first place.

As it fits in this discussion, and your lesson to not ever call me a liar, Nissan's V6 motors and engine code variations goes a little something like this:

1989-1994 Maximas GXE's used the VG series motor, as in the VG30E. Which was 160Hp/182tq btw. It was also the same series used in everything from Infinity J30 to the 300zx NA and TT to the Xterra and Frontiers of today. It was phased out in the Maxima and 300z's, but still in use in the Xterras and Frontiers. Engine codes ranged from the VG30E to the VG33ER in the Eaton supercharged frontier. SAME block, hence the reason for the SAME VG prefix. These were all Aluminum blocks with Iron heads.

1992-1994 Maxima SE's used the POS VE motors. They upped the HP to 190, but the Variable intake runners and timing was a PITA. Probably the main reason why the 300z's STAYED with the VG motors thru these years. There was some differences in the BLOCKS of the VG's vs the VE's, probably why their parts are not interchangeable. DIFFERENT engine codes. Aluminum block with Iron heads.

1995-present Maximas sported the all new VQ series motor which is also used in the Pathfinder, 350z, Altima, and Frontier. It has designations of VQ30DE from 95-99 in Maximas. They went to VQ30DE-K in 2000-2001, which only changed due to variable intake manifold. Then in 2002 to today they are using the VQ35DE, which is the same motor that is in the 350z as well. The VQ35's have most of the internal parts totally new, and therefore different than the VQ30's on top of the obvious displacement difference and THEREFORE NOT interchangeable with each other even though they share the VQ badge. This motor series is ALL aluminum.



You want to still question me and call me names?

A VQ30DE is indeed the same block as a VQ30DE in any other model. There can be differences in HP/TQ and some other things, but that is due to other differences. Same thing applies to the VG series as well.

So now that you have the LONG answer, I hope it helps. I still stand by my initial comment. Look at the engine codes and if they match, they are likely to be the same in many other ways INCLUDING the block and possibly the heads.

I don't like to be called a liar. Especially when I've OWNED and more importantly MODDED several MAXIMAS.....

Now
let me restate my statement

Your a liar
Nothing from the VQ30DETT will fit a VQ30DET
(other than random small ass things)

read carefully.

you stated all VQs are short answer...the same right?
and my short answer
is your wrong

#1. Learn how to spell. It's YOU'RE, not your.
#2. Please quote me where I said "all" VQ's are the "short answer". I said the short answer to "Is Maxima v6 block same as 300zx?", which is what this whole thread was about, is yes since in SOME years they indeed are the same BLOCKS.
#3. If he'd asked specifically certain years, then my "short answer" may have been different. Since we have no clue what year Maxima nor what year 300z he is referring to, we are left to assume certain things.
#4. The reason why parts off a VQ30DET and DETT do not interchange is because one is a RACE engine that is not available in U.S. production cars. Is like comparing a Honda race-only engine to a Honda street production engine. They're both Honda, but not interchangeable.
#5. Take the VQ30DE and compare it to the VQ30DET and compare the differences. Same bore. Same stroke. SAME BLOCK. Only difference is compression ratios. One has 9:1, and the other has 10:1. So in FOR THIS THREAD'S PURPOSE, the answer would be "yes". Take the VQ30DE and the VQ30DE-K. Only difference between the two is that the "K" added a dual runner manifold. BLOCK IS STILL THE SAME. So again, in THAT example the answer again would be "yes". VQ30DET vs VQ30DETT, both which are not even available here nor available on Maximas so it's moot , the answer would be "NO". Get it? Probably not.
