There's more to the engines than just displacement. Unless other differences like VVEL, 11.0:1 compression, intake manifold design, twin throttle bodies and the reinforcements and changes to the block design that trickle down from development of the block for the GT-R don't matter.

i hope this thread turns into a primer on torque vs hp, and how it relates to vehicle performance.

No.
Sure, some cars have boatloads of torque (Viper, ZR1, CTS-V, etc.)... but unless there is the HP ALSO to back it up, the acceleration will be dissappointing... look at any typical high torque/low HP diesel setup. One can lust after the 560 ft/lbs of torque in the a Viper, but there is also the 600 HP to support it in the higher revs. For instance, there are lots of fast cars with high HP/low torque ratings (M3, F430, etc.)... but there aren't fast cars with high torque/low HP ratings... |

Yeh, what sense would it make to put a truck engine (designed for torque) in a sports car? Hmm, I guess they did it in the 240SX and Mitsubishi Starion? Oh, and the Viper. I could be wrong. Anyway, I digress. You could add volume by more bore and less of stroke so you do not add the extra length and weight to the crankshafts. Or go a head and stroke it and use some titanium rods to lighten things up so engine will spin. Anyway, I am delirious from the flight I just took here from Germany and suffering from a cold so I could be talking nonsense and wouldn't even know it.
2. The Viper's V10 is based on the Ram V10 which is itself derived from Chrysler's LA engine, but the Viper's block is cast in aluminum instead of iron. Not to mention 1st and early 2nd gen cars had forged internals which took to boost quite well. The motors share some similarities, but there are enough differences to differentiate them from one another. It would be like comparing GM's Vortec truck V8s to an LSx Corvette motor. |

1. Everyone agrees that the 240SX is a dog compared to its CA and SR powered JDM bretheren. Find me one person that would rather have a stock cast iron block KA over a stock aluminum block and turbocharged SR20DET under the hood of their Silvia/240.

i have a feeling nissan is going to offer the 4.5L V8 in 2-3yrs. thats probably why they didnt bump the Hp from the 3.7L V6.

__________________ Am I the only one here who noticed that the new FX got a 5.0L V8 in place of its old 4.5L unit? And am I the only person here who expects that engine to find its way into the redesigned M creating an M50 to replace the underpowered M45? And am I the only one here who sees the 4.5 on its way out the door which means that there won't be a 4.5 to stuff into the Z or...no wait...yah I'm the only one who notices these things. |

i think of it this way. Smaller engine or displacement makes for a quicker revving and faster response. Bigger engine or displacement although it is very powerful once it gets going will not be as quick in rev timing on the start. Slow moving yet powerful enough for a truck will not work as a sports car. Im sure they can make it happen for a Z..i was just wondering to save $ they should of just made it out of the 4.0 instead of developing a 3.7.

In the future of the 370z though we all know the engine is probably going to be used in the maxima,altima as well. What kinda ticked me after the fact of buying a Z was that i expected to have the Z with an engine that no other nissan should of had cause on the road although the Z looks sexy technically it's a 2 door maxima. If it is going to be a "sports car" dont use the engine for a family car as well.
If you remember the older infinite i or j30's they also had the 300 zx engine NA of course, but you know what i mean. |

Besides, the Z's motor since the introduction of the HR in '07 (and to a lesser extent, the introduction of the Rev-Up) is exclusive to the Z throughout the Nissan lineup so I really don't see what the big fuss is. Yes the HR is used throughout the Infiniti lineup, but in that sense, it's not being used in Nissans "lesser" than the Z. If anything, it's being used in a car "lesser" than Infinitis and in that regard, Z owners should be thankful that Nissan didn't sabotage the Z's output to give the G37 a "hp edge." |

This engine has been used in the G37 coupe since the 2008 model. The transmissions, 14" Akebono brakes, suspension design and many of the other "new" features (nav screen, push button start, bluetooth) of the 370Z are all inherited from the G. The 370Z is basically a shorter, lighter, sportier version of what you can already get with a G37 coupe. Since the Z returned with the 350Z, it's shared the vast majority of it's drivetrain components with the G and will continue to do so as long as it's financially viable for Nissan. |
Wow every thread turns into an argument over some crap.
"get my facts straight" you said huh? So you tell me if im wrong that the 3.5 engine is or is not used in the Z, Maxima and the Altima not to mention the FX plus g35 as of today? Sure the manifolds may be different but the break down is the same damn engine. So what facts are you telling me to get straight? Different as far as looks, style and chassis yes, but the engine is the same damn one. I know that the 3.7 has appeared in the G37 and now the Z, but it will eventually make its way into the Altima and Maxima yet again. I can't only complain about Nissan doing this. Remember the Lexus SC400? Had the NA Supra engine in that baby. Honda if you ask me had the most multitude of different engines in the 90's to split between Honda and Acura with the SOHC/DOHC 1.6 or 1.8 or 2.4 (5 cylinder Acura Vigor) Vtec and non Vtec and the 2.7 V6 Accord was available as well. I dont care about the platform what im specifically talking about is the engine itself. Dont get me wrong im happy and i love the Z, just knowing the engine is the same urks me so to say. Its like ok we know the GTR is a super car. But if the Z competes with say the Evo's or the STi's or the S2000's..what im saying is you dont see a civic with a s2000 engine or a normal lancer/galant with an Evo engine, or a regular WRX with an STI engine. Z is the normal mans Sports car then make it different besides it's looks. the main fact is yes, Nissan will save money this way. We all know that. |

well it took 5 years to go from a 3.5 to a 3.7, so a Z with a 4.0 should come out in roughly 2016

The VQ in the Maxima shares some basic architecture but you can't even swap the block. It's designed for a transverse application, you cannot take a block from a Maxima and drop it into the Z or vice versa. The heads and cams are different. They share the VQ designation because of the engineering principles but they're not the exact same engine. However, the VQ from the Z IS the same as the one previously used in the FX, G, M, etc.. because it's the same platform. The Maxima is the A platform, Z is the FM. Engines are not universal between the two. |
