I'm wondering if I asked about minor details from year to year, like MPG changes, transmission changes, etc., if anyone would know these kinds of little details? Just wanted to ask before typing out a long post.
Here are a few that I am aware of; although this list is not all inclusive:
1995 was the original model year for the B14 Sentra
1996 - OBDII was used in all cars (my understanding is that not all 1995 Sentras were equipped this way)
1997 - ???
1998 - New front end to the cars, honeycomb grille
1999 - Base model Sentra eliminated; low-end model became the XE, GLE also eliminated; Limited Edition package made optional for the GXE instead, Front end reworked again with clear headlights, new plastic cover to the grille (maybe not the world's greatest description), 1999 was also the last year Sentra where at least some models were built in the USA--production went exclusively to Mexico (at least in the North American market) starting with the 2000 model year. 1999 was also the last year for B14.
As stated above, this list is not all-inclusive. It is my best attempt, from what immediately comes to mind. If anybody else can think of other changes, please feel free to join in.

Also about the cams.......they are not measured in ratios. They are measured in lift and duration. The cams from the 91-93 SR are actually much better than later years. The lift is the same but the duration is quite a bit more. A cheap and easy mod for around 6 hp.

Thanks guys, but I wasn't asking you to list all the changes you knew. Sorry. I just wanted to see if anyone would know these kinds of details before I spent the time asking.
I'm looking to buy a '95-'98 200SX SE (1.6L) 5 speed, though I might take a '95-'99 Sentra if I came across a good enough deal. I'm tired of driving my current gas guzzler and am planning to make a lot of long trips, so I'm hoping to hit about 40 MPG. I'm having trouble figuring out the exact gas mileage on various years, and why it changed. Half of the reason I'm asking is because I'm just curious. Note I'm only talking about the 1.6L with 5 spd manual transmissions.
Edmunds and fueleconomy.gov don't agree exactly on gas mileage on the 200SX/Sentra.
fueleconomy.gov says '95-'96 Sentra/200SX (it doesn't list them separately) is rated at 30/40 MPG, but the '97-'99 went down to 29/39. Is that true? If so, I'm just curious what change made it go down?
Edmunds.com, however, says the '97-'99 Sentra still gets 30/40 MPG. Edmunds also lists the '97 200SX at 30/39 MPG and '98 200SX at 29/39 MPG, but I think it should be the same as the Sentra.
Is Edmunds often wrong? It seems they are since nissannews.com lists the '97 200SX at 30/40 MPG, and because the Sentra and 200SX have the same engines I don't see how the 200SX could be rated lower. I think the 200SX even weighs a bit less than the Sentra. Unless the 200SX's rear spoiler hurt MPG (or wheel size?). Again, I know that isn't much different, but I'm just curious (if that's true) what changed.
Note that autos.msn.com also agrees with Edmunds for the 200SX (39 MPG in 97 & 98). Perhaps they just get their data from Edmunds. Anyone know?
A person giving a review here says they only got 33 highway MPG in their '95 1.6L 5 speed Sentra. Is that normal? Or do some people actually get 40?
Changing from 14" tires vs. 13" shouldn't change it that much. Besides, the 200SX and some of the Sentra models came with 14".
BTW, Edmunds says the '95 Sentra has the same engine as previous models, but from the '94 model to the '95 model, the highway MPG went from 35 to 40. The engine even got 5 more HP in '95. Is that right? Was the '95+ engine really improved/tuned for MPG? Different gearing? Was the newer body design much more aerodynamic? This says the drag was .33 for '95-'99. I don't know about before that (they dont list them). Anyone know?
Was '95 that the year they added NVTCS (Nissan's Variable Valve Timing Control System) to Sentra/200SX?
I'm also wondering why the 200SX weight changes were so strange from year to year.
This and this say the '95 & '96 SE curb weight with manual = 2366, and auto = 2427.
This says the '97 SE curb weight for manual = 2456, and auto only 2399.
How could car with the manual gain so much weight from 96-97 yet the car auto lose weight, and how could the car with the auto end up weighing less than the manual in 97?
This goes back to being normal, with the '98 SE curb weight for manual = 2418, and auto = 2474.

Re the fuel milage.
Yes there were differences in tires and front end styling. You are also talking about 1 mpg.
If I remember some cars had a mpg change (and a slight HP change) going from OBDI to OBDII.
30 mpg means 29.45 to 30.44 29 mpg means 28.45 to 29.44
And as they say your milage will vary....
My 97 GXE 5sp did 35 to 38 mpg on long trips when it was new. now with higher speed limits and wider tyres I get around 32 or less.
Re: curb weights. I think you have just found a typo or error.

In general its difficult to get the Highway or city mpg because the test does not mimic typical driving. The speeds and acceleration curves are very low.
I suggest you look up the driving cycle and if you can drive like that, then you might get the 40 mpg.
Yes, the later engine with 5hp extra was a improved version. I believe Wes said it was the head and intake that was improved.
No the VVCS was added earlier.
I dont know about the Aerodynamic improvements, but if the top speed is 60 then I dont think it will make to much difference. Clearly at higher speed it has much more effect. (drag is proportional to speed squared or worse.)
Link
So what change did they do in '98 to make it go down?
your link says the tyres are now 185 14's instead of 175 / 13's
Other than that I dont know. I dont believe there is much difference year to year from 95 to 99 as far as mpg goes. your driving style and speed will make far more difference.
14" tires already came on some models. It's saying they then also came on the base models.
Yes agreed, and my understanding is that EPA milage is typically tested on the car of the manufactures choice, which is usually the lightest and narrowest tired model they have. They dont re-test all the trim levels.
You are still worrying about 1 mpg here, when your driving style can and will move this number by 5 or 10 mpg down.
Sorry. I just wanted to see if anyone would know these kinds of details before I spent the time asking.
