Hi,
J35 and VQ37, both engines are my favorite in the 6 cylinder field.
VQ series got award consecutively about 13 years. it is smooth, powerful, torquey and extremely reliable.

J35, I think it has all advantages VQ does. and it has ivetc with great sound.


What do you guys think about these two awesome v6s? Which one is better or you like better?

 

different engines, different characteristics...
you cant compare the two.

one has low end torque
and the other has HIGH end torque

one powers a RWD chassis, the other drives the front wheels.....
Obviously, we're on the Acura forums and we all have the J-series engine.....

 

also the six cylinder honda engines DO NOT HAVE IVTEC!
its full VTEC.

only the honda 4 cylinders have IVTEC

 

the VQ also has Variable Valve timing..... same thing as vtec

 

VQ also powers fwd like Maxima.

looks like VQ has more awards.

is J series as good as VQ?

 

was this your agenda all along????

 

I'm pretty good at smelling bullshit.

 

and your agenda is smelling pretty bad, right about now.

 

I guarantee you're the only person who cares about the VQ's awards.

 

J35 is SOHC vs VQ37 is DOHC

Or am I wrong in this?

you sir, are correct. the J is SOHC

 

The J series is a much more smoother and refined V6 than the VQ. There's no argument there. My ex has a 7th gen Maxima and there's no comparing the 2. VQ feels more raw and unrefined. The newer Q50 I believe finally ditched the VQ in favor of the VR engine. VQ is old and outdated by today's standards. Of course, the J series has been around for awhile as well but much more refined.

 

^thats because they are totally different. and you cant compare apples to oranges!

 

ha, not really, if so, I would not be here.
Before long weekend, just want to have some discussion on both excellent engines. to talk about their features

 

we can have a decent discussion! but once we start going into subjective or opinions, then its not so much fun...as every one has an opinion!! like for example, the awards.... no one chooses a car because an engine won an award...

you'll also get people stating things like...ones smoother than the other, etc.
But if one has never driven the other car, how would one know!? subjective!

both engines are designed very differently. as one poster stated, DOHC vs SOHC

 

Much agree. My limited experience is only with the G37 and 4G TL FWD.

They both get the job done but the VQ37 is not as refined as the J series. Part of the problem might be because of the 7AT transmission which has more of a sporty than smooth shift pattern.

I wouldn't mind owning any of these though.

 

I'm curious why you want to compare the VQ 3.7L to the J 3.5L. Both engines are produced in 3.5 and 3.7 sizes.
VQ is a big bore and short stroke while the J is a long stroke.
Anybody (including Kia) can make a good short stroke engine.
Short strokes are relatively thermally inefficient and usually don't get the MPG as stated by the EPA.
I do like the VQ utilization of a timing chain (although slightly less mechanically efficient) instead of a belt like the J.
The J requires a belt change every 100k miles ($500 to $1,000)

 

Not necessarily....the VQ35 I had in my 2002 Maxima it was one of the smoothest V6 I ever driven, only the BMW inline 6 was (marginally) better. In 3.7 form (and with significantly increased power) it did get a bit more "thrashy"...however the Q50 has improved on this regard compared to the G37. Overall yes, the J37 of my TL SH-AWD was a little bit smoother than the VQ37 of my current Q50 Sport AWD but nothing too serious.

Both absolutely excellent engines among the best V6 around.

 

I had an '02 I35 which is essentially the same engine as the 5th gen Maxima and I agree it was smooth but just not quite up to par with the J series in terms of refinement. And you can't really compare an I6 vs a V6. The inline configuration will always be smoother lol.

 

The Nissan VQ37 (DOHC) is able to generate more hp/liter than the Honda J37 (SOHC).

Unless Honda moves the J-series V6 engines onto DOHC heads, it will always be behind the Nissan ones in hp output from the same engine displacement.

 

100% true, I had a 2002 Maxima and it was one of my favorite cars. It's definitely very smooth and reliable.

 

the same... But different. Nissans/infinitis VVEL is more for fuel economy purposes, as opposed to power. It definitely doesn't have the VTEC engagement sound, like Hondas do.

Honda had versions of VTEC (I believe it was called E-vtec) and it was specifically for improving fuel economy at higher rpm, as opposed to creating moar Powah. This was on civics in the early to mid 90s. Not sure if they still have it. Either way...

 

Not really true. Both engines have peak torque diminished high in the rpm range. It is true the VQ has good low end torque, but I wouldn't say the J series has high end torque. It has high end horsepower. Depending on which version of the VQ, some don't make sense to redline because they lack high end horsepower. J series always have high end horsepower, due to VTEC.
