What is the difference between the VE and VG engine and I know about the power increase with the y-pipe, how much do you get with adding a b pipe as well?

 

First off..the VG and VE engines were used in the third gen Maximas (89-94). One of them was DOHC and produced 190hp while the other one was SOHC and produced 160hp. I don't know which one is which as I always get confused by them.

The 4th gen Maxima (95-99) and 5th gen Maxima (2000+) have the VQ engine which is totally different from the VE & VG engines. The VQ is all-alluminum, has a nearly flat torque curve, and is DOHC. It also produces 190hp in the 4th gen Max and 222hp in the 5th gen Max.

For a full details on it, check the FAQ on this site as they have a very good article written on it.

Hope this helps.

 

The VG30E engine is used in all 89-91 Maximas. It is a 3.0 liter(2960cc) V6 SOHC engine that makes 160 hp@5200rpm and 182 ft-lbs@3200 rpm.

The VE30E engine became available in the 92-94 Maxima SE. It is a 3.0 liter (2960cc) V6 DOHC engine that makes 190 hp@5600 rpm and 190 ft-lbs@4000 rpm. The 92-94 Maxima GXE models retained the VG30E engine.

 

In all honesty it's cool that you post, but in the furture you should check the past post to see if this topic has been covered before. I'm not ******* you just making a suggestion. You might even get a better explanation.

 

While on the subject... I noticed that the VG gets all of its torque (182ft-lbs.) down at 3200 rpm while the VE (190 ft-lbs.) gets it down at 4000 rpm.

I know the performance numbers decently for both engines, but what am I missing? Is the VG a whole lot slower than the VE? I know the horsepower numbers are pretty damn different, but the torque numbers arent, shouldn't that make both engines yield near identical performance numbers? Any type of enlightenment here is appreciated. I'm a bit confused when it comes down to this subject. Thankyou in advance.

 

Most of the differences have to do w/ breathing ability. The VG have 2-valve heads while the Ve has 4-valve heads. 2-valvers are good for low end torque but don't seem to breath well up high. 4-valve heads breath really well up high but have torque generating problems down low. There are other differences but this one fact is responsible for most of it.

 

So with that in mind, would you say it's easier to spin the tires in an '89 SE versus a '92 SE?

 

i have beaten a few ve's off the line but once they get in 2nd or 3rd, i start commenting how nice their tail lights look.

 

I read a very good article concerning torque vs. Hp. I don't remember where I found it, but it stated that horse power is a product of torque and RPM. It even gave a formula that I also don't remember. According to the formula, there is a certain RPM where the torque and HP are always equal(2525 rpm i think). Anyway, if I read it correctly it could be summarized like this: For sports cars, torque is good but horse power is better. Making alot of torque is good, making torque at higher rpm is better even if peak torque is not quite as high. In fairness to the author of whatever I read, I should try to find it and post a link because I am not sure about my translation. I will start searching.

 

Does anyone know what the differences are between the VG30E and the VE30DE? I know the VE is DOHC and the VG is SOHC and the VE used direct-fire coils and all that jazz. I am very familiar with the VG30, but I know nothing about the VE30DE. I need to learn because I have to take some stuff apart to get to my coolant leak, but I would really like to talk to someone who knows the VE30DE inside and out.

Do they use the same or similar blocks and rotating assemblies? What's with the wierd dual-stage intake? Is there a specific RPM the VTC's come on? Etc...

Please don't take this the wrong way. I could write a 3 page essay on the differences between the VG and VE, but it wouldn't even come close to addressing your coolant leak problem. If you are really serious about learning the differences between the VG and VE, but the Nissan FSM for your year. It will cover the VG and VE both and be most valuable for your repair requirements also. Best $70 or so I ever spent.

Here is that write-up that I was thinking about.
