Is Maxima v6 block same as 300zx?

[DaRussian]

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.

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:

• 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

Thank you, Wiki-san.

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.
