Hi, Im getting a 300zx that has a locked up motor, and i have a maxima 3.0 engine sitting at the house, and i just wanted to find out if they have the same block and head.?? does anybody know? thanks
Is Maxima v6 block same as 300zx?

Depends on the years, but the short answer is yes.
BTW, next time if you just cross check the engine names/codes you will be able to answer the question easier. VQ30=VQ30 regardless of model it's in.

agree as well.
so true...
Are you sure? Cause I know the fact that KA24 from 240sx are different from the Altimas', and SR20 from S13 are different from a lot of other SR20 cars.
liar
i cant use anything from a VQ30DETT on my VQ30DET
almost everything is different
the entire engine code has to be the exact same
KA24E = SOHC
KA24DE = DOHC
facebook.com/ballengine
S13 SR20DET 205ps T25 turbo No variable timing
S14 SR20DET 220ps T28 turbo Intake variable timing
S15 SR20DET 250ps T28 turbo ball bearing Intake exhaust variable timing
There are too many difference between the SR20DET used on different cars. But if the RWD SR20 has this much difference already, I am pretty sure there must be difference between a FWD and a RWD VG30, just like VQ35 from Z33 and Maxima are different.
Your point does not make sense...
Also, found this on NICO
I've heard of a couple of differences between the vg30de motors. I don't know if it's specifically between the infiniti and the Z and/ or the maxima too.The oil dipstick on the infiniti motor is by the #1 cylinder as opposed to cylinder #6 on the Z.
I have also heard that the waterpump snout is a different length on one of the motors. This might suggest that the alternator pulley and crank pullies are different too.

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.....
As far as I know VQ from 350z and Maxima is not interchangeable.
Why not? The new Maximas use the VQ35DE and the 350z uses the VQ35DE. What's different?

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
I am not sure on the VQ. My knowledge field in Nissan engine is only in the SR now.
There are AWD, FWD, and RWD SR engines out there, and the block from the AWD and FWD SR are different from the RWD SR engine, meaning you cannot use a GTiR's block and S-chassis transmission to do a swap. That's why people import SR engines to the state. The engine mounts, for example, are located in different location. Not everything fits the same in a RWD platform to FWD and AWD platform. The reason FWD and AWD can do is because the different among them is the transmission. The engine is located in the same position. I believe engine mounts are important because they hold the engine into the engine bay. So, if the position of them are different, they cannot interchange.

#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

depending on the years some maximas are vg30's same motor... just FWD. its like the bluebird sr same motor as the 240 sr but ones fwd and ones rwd... u might be able to make it work.. but itll be alot of work involved...
Former Maxima owner, and lover here also.
Negative. Ones a VG30DETT, and the A32 gen Maxima uses a VQ30DE, which was the predecessor for the motor in the 350 and various other Nissan cars today. Same displacement different motor.
The older, gen pre-1995 Maxima (A31?) shared a the same VG designated motor as the 300zx, but I believe there were some differences between the two.
right there you said it
vq=vq
it was more of a EVERY VQ30 IS NOT THE SAME post.
i was simply pointing out that the VQ30dett and VQ30det (which i own) are not the same.
thats all
you took it too far and literal, i said it as a sarcastic jab...but you got on your high horse.
no big deal.
but your still wrong in your original statement.
And i dont have to spell correctly, this is the internet, not english class.
~subscribes~
~ends self~
no jamie is right in answering the question.He is soley talking about the block. NOT the engine as a whole.Everyone seems to be thinkin a block= engine.just my thoughts. If im wrong the so be it.
I got dinner to goto.
True, but also consider this:
VG30E, not the DE, was used in 84-89 in the 300ZX AS WELL AS 84-94 Maximas. So if the OP has a VG30E block laying around and the 300zx he has is an 84-89, then again the answer would be "yes". Right? Eventhough the 300z moved up to the VG30DE in 90, it still maintained the exact same bore and stroke and displacement of the previous year's VG30E, so therefore it would also possibly be the same block, possibly same heads, just different intake manifold. Again, there are many possible variations like this where a "Maxima" motor is indeed very much like the "300zx" motor so it MAY be the same block too. Follow?
As explained above, there are some differences in some of the VG's but it may not make a difference in respect to the BLOCK and possibly the heads.The older, gen pre-1995 Maxima (A31?) shared a the same VG designated motor as the 300zx, but I believe there were some differences between the two.
300zx and Maximas are the same, in fact the Maxima used the TT block meaning it can handle up to 20lbs or so stock with a single turbo setup running a Z ECU.
Listen, if you couldn't read the part where I said "SHORT ANSWER", ie. generalizing, then why would I expect you to understand that the point WASN'T that EVERY VQ motor is the same but rather that a VQ30DE is indeed the SAME block as any other VQ30DE regardless of what car it came from. I've more than explained myself by now for you to be satisfied that was my point. Maybe I should've chewed everything up and spit it out for all the short bus riders. I guess it's too much to ask that people not split hairs about something so trivial. Then again, this is IA, so it's to be expected.
BFD.....neither of those two motors are available HERE so therefore the OP wouldn't likely have EITHER ONE sitting in his garage and hence his question. So basically you interjected something that did not answer the question posted and merely split hairs about 5 characters I typed that only YOU took 100% literally. Let me just go into a sewing machine discussion and tell them that about boats....i was simply pointing out that the VQ30dett and VQ30det (which i own) are not the same.DUR DUR.
There you go. Just like I stated above. If you hadn't called me a "liar" when I wasn't lying, then maybe I would've let you go off on your tangent about motors that don't apply to the discussion.you took it too far and literal, i said it as a sarcastic jab...but you got on your high horse.
no big deal.
When it is read incorrectly, probably so.but your still wrong in your original statement.
Whatever makes you sleep better.And i dont have to spell correctly, this is the internet, not english class.
Be careful, the guy from Japan where they have motors that are NOT available here is going to come in and argue with you that you mean ALL 300z's and ALL Maximas are the same.....
84-94 maximas had a vg30e FWD. This motor is the same as the 84-89 300zx non turbo motor but the 300zx is RWD. Both the motors in the 89-94 maxima and the motor in the 84-89 non turbo 300zx are SOHC 3.0 liter v6's with cast iron blocks and aluminum heads with timing belts. The 90-96 300zx has a vg30de(non turbo) or a vg30dett(twin turbo) which is a DOHC 3.0 liter v6 with cast iron block and aluminum heads with a timing belt. The 95-01 maxima had a vq30de which is still a DOHC 3.0 liter v6 but has a aluminum block and heads and has a timing chain not a belt.
I used to think that the 95-01 maxima's had the same motor as the 90-96 300zx but they don't. Very different. I always thought it would be cool to put a vg30dett into a 95-01 maxima. It still could be done and probably has just not as easy as I once thought. Hope this helps and good luck with your 300zx. They are fun but expensive. I own a 93 non-turbo. I love it.
-Homeless Ronald
Right, that's because one is a VG30E (and post 91 a VG30DE) in the 300z and a VQ30DE in the Maxima. Just like an SR motor is not the same as a KA motor.
The chassis code is J30. A31 is a RWD Cefiro chassis code.
sorry that was my brother who made this thread and he was refering to a v6 3.0 vq30de engine from 02 maxima and a 92 300zx with vg30de engine. are the block or heads the same on theses engines?
In this scenario, the answer would be no. The VQ is all aluminum and the VG is not. They also have different bore and stroke and compression.
ok so the vq30de and vq30de have nothing in common? correct?
Dude, seriously, read the thread. The VQ30DE is a VQ30DE. Your question makes no sense. I think you meant a VG30 and a VQ30. To that, the answer is....no, they are NOT interchangeable.
wow some people like to make things alot more complicated than it really is.... its a simple answer which was answere din the first couple of posts..
*lol to the guy talkin about sr engines*
yea thats what i ment
VQ30DE
The 3.0 L (2,987 cc) VQ30DE produces 190 to 227 hp (142 to 169 kW) @6400 rpm and 205 to 217 ft·lbf (277 to 294 Nm) @4400 rpm. Bore and stroke are 93 mm and 73.3 mm with a compression ratio of 10.0:1. The VQ30DE was on the Ward's 10 Best Engines list from 1995 through 2001. It is an aluminum open deck block design with microfinished internals and relatively light weight.
An improved version of the VQ30DE is known as the VQ30DE-K. The K designation was for the Japanese word kaizen which translates to "improvement". The engine was used from 2000-2001 Nissan Maxima and adds a true dual-runner intake manifold for better high-end performance compared to some earlier Japanese and Middle-East market versions of this engine. The VQ30DEK produces 222 hp (166 kW). The 1995-1999 US spec VQ30DE was equipped with only a single runner intake manifold.
It is fitted to the following vehicles:
- 1994–1998 Nissan Cefiro (A32), 217 hp (162 kW) and 206 ft·lbf (279 Nm)
- 1995–1999 Nissan QX (A32)
- 1995–1999 Nissan Maxima (A32), 190 hp (142 kW) and 214 ft·lbf (291 Nm)
- 1996–1999 Infiniti I30 (A32), 190 hp (142 kW)
- 2000–2001 Nissan Maxima (A33), 222 hp (166 kW); 227 hp (169 kW) for Anniversary Edition SE
- 2000–2001 Infiniti I30 (A33), 227 hp (169 kW)
- 1999–2003 Nissan Bassara U30, 220 hp (164 kW) and 206 ft·lbf (280 Nm)
- 1998–2003 Nissan Presage U30, 220 hp (164 kW) and 206 ft·lbf (280 Nm)
VG30DE
The 3.0 L (2960 cc) VG30DE produces 185 to 227 hp and 198 ft.lbf. Bore is 3.43 in (87 mm) and stroke is 3.27 in (83 mm).
It is used in the following vehicles:
Thank you, Wiki-san.
- 1990–1996 Nissan 300ZX
- 1987–1999 Nissan Fairlady Z
- 1993–1998 Infiniti J30 and Nissan Leopard
- 1992–1995 Nissan Gloria and Cedric
- 1989–1991 Nissan Cima
You'll notice that there's no Maxima listed for VG30DE? Well, here's why:
VG30E
The 3.0 L (2960 cc) VG30E produced 153 hp and 182 ft.lbf. Bore is 3.43 in (87 mm) and stroke is 3.27 in (83 mm). In 300ZX form, it produced 160hp and 174lb-ft. 1988 saw the 300ZX gain 5 more horses for a total of 165; however, torque ratings remained the same. In 1989, the Maxima received the 160hp rating, but also used a variable intake plenum that let it make 182lb-ft@3200rpm. Strangely, the 300ZX never received the variable intake plenum.
It was used in the following vehicles:
- 1984–1989 Nissan 300ZX/Nissan Fairlady Z
- 1984–1994 Nissan Maxima
- 1987–1988 Nissan 200SX SE
- 1990–1991 Infiniti M30/Nissan Leopard
- 1990–1996 Hardbody Truck
- 1990–1995 Nissan Pathfinder/Nissan Terrano
- 1992–1999 Nissan Gloria/Nissan Cedric (179 hp)
- 1992–1998 Nissan Quest/Mercury Villager (modified to become a non-interference design)
I hope this answers EVERYONE's questions.
Edit: Ok, I re-read it, and realized some of you won't get it. You'll notice that the VG30DE was never used in a FWD application. Only RWDs. VG30E (SOHC version) Was used in FWD's and RWD's, the block is identical but will obviously have minor differences such as mounting points (Fixable) and accessory positioning (Fixable). Short answer: If you want to swap a FWD to a RWD VG30E you can do it, or vice versa, with enough time and a decent knowledge of the differences in a FWD and RWD set-up. VQ30DE and VG30DE are different beasts, however. You'll notice that VQ is 93x73mm, while VG is 87x83. Different blocks, different heads, totally different engine. Also, a VG30DE and a VG30E are the same block, so if you wanted to make a VG30DE with a VG30E block, then you'd need to do a head swap. Not exactly brain surgery if you're already mating it to a tranny, rebuilding mounting points and accessory drives.
Do I think you should do it? No, because very likely it's a lot more work than you think it is to try and do it. Is it possible? Sure, it is possible.
