I can't understand the complaints about the N/A V6 engines in the Xterras. When you compare the specs with other mid sized SUV's, the engine size 3.3L and 180HP is about average.

It is a truck after all. I don't think many SUV's are going to throw you back in the seat when you punch the gas. They just aren't built that way.

Perhaps it's because we are higher up off the ground that we don't notice the speed as much compared to driving a Honda civic.

I have the Automatic N/A V6 and when the stop light turns green, I shoot ahead of everybody without even realizing it.

Keep in mind that I was driving a 4 cyclinder Kia Sportage before I got my X so believe me, my Xterra is a huge improvement in power and much quieter.

If you want to pass on the freeway, just hit the O/D off button for quick horsepower.

It seems like a lot of people don't appreciate what they are driving. It's a 2 ton truck! not a fiberglass corvette!

Your 4x2 has a slight weight advantage...

I dunno. For me, I enjoy the combination of the supercharger and the 5 speed. Makes it a very fun, enjoyable vehicle to drive. I love surprising assholes on the freeway who think I'm in a "big lumbering truck".

And every morning I have to dive for the carpool lane I am doubly thankful for the supercharger/5 speed combo. That extra merging power is much appreciated.

I drove an NA Automatic for a week and it was drivable - but there wasn't as much room for error - you definitely had to pay attention and plan ahead.

You guys who say the 3.3 is slow don’t know what your talking about, before this vehicle I had an 86 Isuzu trooper that wouldn’t go over 50mph on flat ground with a top speed of 75 down hill, and it wasn’t that bad being that you can only drive 55-65 anyways. If you want to go fast get a sports car, but the Xterra with a 104mph top speed (mine anyways) isn’t bad at all.

You are all nearly at sea level, as am I (419 feet, to be exact). Drive your Xterra to, say, Denver and report back on your acceleration impressions.

Many of the folks on this forum live in mountainous or higher elevation areas and that takes a major toll on the available horsepower.

Hahahaha..
I live around sea level (on long island) and the power is acceptable, even with 33's.
However it flat out sucked when I went through Colorado and Arizona with 8k foot plus altitudes.
Can you say 2nd gear going 30mph on the interstates creeping along?!
I'll stick with sea-level, thanx!!
BTW.. I have an air raid intake and a HKS cat back exhaust. So I cant even imagine if the truck was stock..Not fun..

SuperCharger isn't bad at altitude. Even with the auto.

But we do get the folks that don't like the bad drop in power when coming from sea level up to here.

We tend to get a lot of those, as half of California is relocating to the Front Range of the Rockies.

We came out there in the fall of '03 (Broomfield area) to do some work. We brought our Chevy 3500 duallie with us. It's a bad-ass beast here at home (has the 8.1L gas engine), easily smoking the duals from a stop.

We were using it for some testing out there and could hardly get the thing to chirp the rear tires without resorting to power-braking it.

As someone who is considering moving to the front range area (no, not fron Cali) I'm curious if the altitude changes can be dialed into the X somehow to improve performance at altitude?

Bumping timing, making sure it's all dialed in and little things like that will give a bit back. But there's no substitute for atmospheric pressure and oxygen.

Cyclemut,
Does Nissan (or dealerships) install a different PROM or re-program the ECM to deal with the lack of Oxygen?
I know that other manufacturers do that to help with the lack of power.
Im just curious. And I dont plan on moving to the front range. I like it right here at sea level.

It takes oxygen to furn fuel. High up there in CO, there is less oxygen, so you can not burn as much fuel. Less fuel = less power. about the only thing you can do is add oxygen (think a slow blead of NO2), or boost of some kind (SC/Turbo)..
High altitude is where turbos shine.. they are designed to give a set ammount of manifold pressure, so at high alt the turbo spins faster, and has the same boost.. wastegates are cool... superchargers are limited by engine rpm's, you set one up gor peak boost at 8000 feet, you are going to break stuff if you drive down to sea level.

Lower octane fuel seems to help when going into the mountains...higher octane can make it worse.



Sort of a temporary timing change.

I did notice in CO for example that regular octane was lower octane rated than regular octane in NJ, etc...so it looks like the gas stations take the altitude change into account so a rig set up for regular in NJ will run OK in CO (At least after re-fueling...)

You cannot compare the horsepower without also comparing the weight.

I always thought the height made the truck feel faster than it was really going. I get in my '02 Altima and can barely tell I am going 75mph, My X feels like its flying apart at that speed.

As one of the few who have the S/C I can say I'd never have an X without it. It serves my purposes and I had a hec of a time justifying it to the wife when we bought it, but I think she appreciates the umff that it delivers.
Recently on a trip to California I had my Mom drive the first leg and I was astonished that she didn't give it enough gas to even engage the S/C. So I can see where there would be a market for the N/A engines. She currently drives a KIA Sportage and It scares me because it is soooo underpowered.
I guess it boils down to what you want. I would have saved about $1500 bucks on the sticker without it and would also be saving about $50 bucks a month on gas if I could use plain old regular, not to mention the price difference in tires for the 17" wheels, but I like the HP and wouldn't live without it.
OH, It wasn't an option to have the 5-speed in 03 if you were wondering. It was on the Frontier but not the X. I tried to get it that way and they couldn't do it.

Ha! I used to drive a Kia Sportage(5 speed stick shift) and it wasn't so bad, the engine was louder than a bus engine though.

what SUV's are you comparing it to? Because vehicles like the Highlander are FWD, and were never meant to see anything but a paved highway -- so that cannot be the same class.

But the real reason is simple : Numbers mean nothing. It's all the way it's geared, it's weight, and a bunch of other small factors that make the vehicle useful. Afterall, max HP is hypothetical -- and only happens under certain conditions... How does it perform in the range that you're gonna use it. My opinions of the 3.3L 180HP V6 is that it's adequate. Definitely not more than you need -- and less than what I'm used to. "Sluggish" comes to mind.

I don't think it sounds healthy either and this one is an automatic. I remember getting on the freeway once with her in CA, very scary seeing the traffic come up on you at 80MPH.

There's nothing wrong with the N/A V6. It doesn't have much power, but it has a ton of torque, and it'll go right up hills no problem. Remember, this is a truck, not a sports car. When I have a need for raw power, I drive my volvo.

Does a '04 2wd Xterra really weight 5,000 lbs? I thought it was about 4,000 lbs...

I haven't weighed it personally but I quoted my source as edmunds. Interesting, to note some other sources.

2WD, 4WD, dry weight, curb weight, max loaded weight..
can go from just under 4k, to almost 5.5-6k..
keep in mind, after market front bumper, winch, sliders, full skids, and a tire carrier, full tanks of gas.. you are going to be overloaded when you sit inside it.

The X's GVWR is 5,200 lb...anything more than that is over the rated load capacity, and that includes cargo, passengers, fuel, etc.

The curb weight for my X in the manual/plate is 4,200 lb (4wd 5 spd V6...) leaving 1,000 lb to add a driver, passengers, cargo, armor, etc....to get up to 5,200 lb.

Winch, bumper, skids, sliders for me added about 440 lb, I weigh around 220, leaving 340 lb...My two college kids weigh 250 + 150 = 400 lb, so I'm already 60 lb over GVWR w/o the svelt wife or her not so svelt luggage getting on board...throw on some tools, spare parts, highlift, FLIR/UV/XRF equipment, a picnic basket, etc...

If I get around to getting a rear bumper/carrier for the 33" spare to make some room in back...

I'd be at close to 6K pretty easy.

I am about 3 weeks into my 2004 Xterra NA V6 ownership.

I had been driving my wife's Windstar previously.

Now, the Windstar has power. It has a larger engine (3.8L), 200HP and about 230-240FTLBS. Step on it and it takes you away.

Did I feel the difference switching to the X? Sure.

I had the choice of either a Frontier SVE (crewcab long bed 4x4) or my X. They didn't have SC Xterra's left. I decided to go with the X.

The main reason is this : I don't want to pay for premium gas.

All in all, I'm pretty happy with what I have.

It's not a sports car, but has enough torque and power to get me to work and back on the highway. And I drive it to Tahoe with no problems.

I live in Evergreen, Colorado at approximately 7800'. No, Xterra's are not the quickest off the line at a stop light, but I have driven much, much worse. The problems with altitude come when towing, typically cutting the tow rating in about half. To make up for the thin air, I use intake and exhaust changes so the engine can breathe better. I also run synthetic everything, so the engine has less Parasitic drag. Seems to help.

Just my 2 cents worth.

You are correct. Mine doesn't even quite make 5000 lbs and it has about 700 lbs of extras on it bringing it to about 4850 or thereabouts.

As far as the engine goes, the 3.3 is an excellent unit and I would never "bash" it, but I will never turn down more power either. When the truck was new and still weighed 4100 lbs I thought it had plenty of power, but now I wish I had more, even if it is technically "enough" right now.
