I am considering having the speed limiter removed from my 2000 GXE(5-speed of course) and would like to know just how much more top end would I pick up. It seems to me that the generation four would do around 143 or so. I am hoping for about the same out of my car. Can this be done by getting an ECU from an SE?

Also... my car is still riding on the stock 15 inch wheels. How much of a change in performance can I expect going up to some 17's? I know it will handle better but will I loose some acceleration? And while I am asking what is a decent size to run?

 

Get the 17s, especially since top speed is something you seem to like. 17s hurt acceleration a bit, but the benefit you get from high speed stability is WELL worth it. With 17s on my car, I could happily cruise all day at top speed if the road allowed, but with 15s, the car feels a bit skittish up there.

I don't know about the 5th gen swapping of ECUs, but in the 4th gen, that would do it! I imagine the 5th gen would be the same.

 

I cruise pretty fast most of the time, usually around 120 or so. Depending on where we are going and if the kids are in the car. My wife gets ****ed when I go over 110 but she has gotten used to it. You are right about the skitish at high speeds. Not to mention that it handles like crap. I really want a set of the factory 17's but since there are not too many Maximas over here (Italy) I will have to wait until I come back to the States.

 

120mph is not crusing my friend...its crazying...hehe

What's the speed limit?

 

a limiter? what's that?

my car didn't come with one at least...hit 155 once when i was going to Vegas...

 

Yes your correct in that statement

 

how u gonna get the limiter removed.......JWT or G force?

 

u sure u have one?(the limiter, of course..)
there have been some reports that GXE 5-speeds are NOT equipped with one..including mine..

i'm not going to ask u to do a test..since it's kinda dangerous..but i don't think JWT or G-Force makes ECUs for our car..

 

155

 

I live in southern Italy and there are no speed limits to speak of. My car hits a limiter a 135 MPH every time. It may be that my car came with the 15 inch steel rims and "H" rated tires, thus the limiter. If your car is making over 150 MPH I am assuming that you had all of your mods at that time. My primary concern is just removing the limiter. If that can be done by grabbing the ECU from an SE than that is all I will do. Maybe later down the road I will look into the Y-Pipe and some other bolt on parts. Right now I just want to make sure it stays reliable while I am over here. I do not trust the Italians to work on any of my cars. Way to many horror stories.

HOW DO YOU INSERT A JPG INTO A POST?

 

I have a GXE auto and it limits at 132 because of the tire rating I believe. Make sure you get some better tires before you're out there continuously cruising through triple digits, Chief.

If your jpg isn't on the net, you have to attach it. If it is, hit the "reply to post" button on this post and see how I did it.

 

Your car is the exact same as mine. I had the fog lights and spoiler installed. I did not get the alloy wheels which I wish I would have done. Of course I paid about $19200 for my car. I bought it there in VA at POMOCO Nissan. My wifes family owns the auto group so it makes it kind of nice.

 

nope! only power train mods i had on my car at that time was Stillen intake and y-pipe..that's it...no pulley, no cat-back, no fuel pressure regulators...

could have gone maybe a tad bit faster, but ran out of straight roads and it started to drizzle a bit..

 

What rims did your car come with from the factory? I am thinking that maybe cars with the crappy 15 inch steel rims are limited and those with the 16 inch alloys are not. I suppose that it would all depend on the speed rating of the factory tires. I know that the Camaro
Z28 is limited to 108 unless you get the upgraded tires. If this is true I wish that I would have known when I bought my car. In the long run it really does not matter. I will get the limiter removed and do some mods when I get back state side. For now I will leave it stock to make sure I have no problems. Have you ever had your car on a dyno? Just curious as to how much power you are putting to the ground. When my car hits the limiter it is still pulling pretty strong at 135 so I feel confident that it will do 145 or so. I honestly thought that it would be redline limited well before 155. What size tires were you running when your spedo indicated 155? It is possible that it could have been off at little.

 

See the pic and the link in my sig. It may work for 5th gens too. Someon has to just step up and try it.

 

Rather than start a new thread I'm just going to ask my question here. I rarely take my Max past 130kph (80mph) but last night on a long straight stretch of highway I was leading an integra on a testosterone-fuelled speed binge and I hit approximately 190kph (120mph). How long does it take to increase your speed at that point because I did not seem to be accelerating much (if at all) despite WOT? I was at about 4000rpm. Is it possible that I can't go any faster? I never got a chance to find out because I had to turn off of the highway. I have already found my maxima's acceleration to be somewhat substandard.

 

Even an exotic has trouble increasing speed from that point, rapidly. You only have 220 or so HP.

Your expectations are not realistic!

As an aside - what are your experiences if you brake from that speed? Even Ray Charles can go fast in a straight line!

 

uh...from 80-120mph...well, we're not the fastest accelerating cars in this category..but then again, exotics(Lambo, Ferrari, Aston Martin)do not have trouble in this speed range..unless ur idea of exotic is a PINTO..

 

150 here....stock.

 

If you guys are all getting 150 or better than I guess these things are alot faster than I thought. I may hold off until I get some better wheels and tires. To be honest I like the factory 17's that come on the SE's. Surely someone will have some for sale when I am in the market. Until then 135 is all I have. BTW when you cruise at 110 or so these things still get about 21 mpg which I think is still pretty damn good. I drive an Alfa 164 with a 2.0 four banger and it will get over 30 mpg at the same speed. Not really important but I found that to be very impressive.

 

i think someone's selling the stock rims in the for sale forum.
i'm selling mine too..

 

The reason I asked is because I felt it would take an extremely long time (if ever) to reach the speeds other people are recording in stock maximas (i.e. 135mph+). I mentioned that my car's acceleration seemed substandard because 8.22sec is my best 0-60 so far (measured with g-tech/pro) and I'm still concerned that there is something amiss with my particular maxima. I can't just blame Calgary's altitude.

As far as braking from that speed it was not a problem. I didn't try braking hard but why would I if I didn't have to?

 

believe it or not..altitude gives u more trouble that u think..

 

I lose about 30hp for the altitude, but I should have gained about 10hp for the -4 degrees C ambient temperature. So I have been operating at about 205hp. Would that account for 0-60 in 8.2 sec and top speed under 125mph?

Check out http://members.home.net/rabeveridge/html/about_hc2.html for the hp calculator I used.

 

I was just asking about speed limiters and ECU swaps in another thread. I'm fairly sure that JWT and G-Force don't make ECUs for the 5ht gen. I was also told that puting a SE ECU into my 2000 GLE was imposible. Jet supposedly makes a piggy back ECU (400), and Haltech makes a whole new ECU (1145).

Does anyone here know anything for sure about swaping an SE ECU without a limiter with my GLE ECU?

Your car hit 155 with a intake and a y-pipe? Sweet! I have the stillen intake and S-03 tires, and my car is just begging to be taken fast. Unfortunately it cuts out at 130.

How did your car handle at 155? Could you have reasonabley gone faster? Also, how big of a difference did your y-pipe make when you put it in?

 

I think another reason for the difference in achieving top speed you're talking about is due to the fact that you have an auto, whereas the others have 5 speeds. So above 100 mph, the quickest way for the 4 speed auto to reach top speed is to s t r e t c h 3rd gear all the way, and then when 3rd is finished, switch to 4th. SInce your gears are spread out a little more, acceleration won't be as great.

With the 5 speeds, we go in 4th gear, to 120 mph rather quickly, switch to 5th gear which will still go to 130 rather quickly, then the stretch (not as long as auto) to top speed. The 5th gen has a variable intake manifold, so top speed is probably achived alot quicker (from 130 mph) than my 4th gen 5 speed. The 4th gens seem to top out around 143 mph with a few mods. 5th gens obviously higher.

yup..just an intake and y-pipe. that's it!
the car was rock solid at that speed(i had my suspension mods at the time minus the Tokicos)..i had to let up the gas pedal cuz i was running out of straight road really really fast(at 155, everything looks like blur )..i guess i could have squeezed a couple more mphs..since the car was still accelerating(although quite slowly at that speed)..

 

I also have 2k GXE 5spd with 15 steelies and hubcaps...Car just doesnt feel safe on the highway, it is all over it. The fastest I went so far was 120 mph. I have started saving up some cash for some inexpensive rims.

 

Damn, you make me want to drive on those west coast roads real bad.

DW

 

i can only do this when i'm going to Vegas...in Cali...that's kinda crazy...hit 150 once in cali...in over 2 years...

 

Yea..I can't wait to get rid of the steel rims on mine. Sometimes I would like to leave the Maxima totally stock looking and put all of my money into making her faster. You know make it a sleeper. But then I don't think that I could stand to look at it with those little tires and rims. Plus like you said the thing handles like a pig. It resembles a hippo with tiny legs from the back. Oh well someday she will have decent rims and tires.

 

i miss my 15inch wheels and fat tires tho...the car was soo plush!

 

I hit 150mph on my 2000 5spd GXE. Mine doesnt have a speed limiter either.

 

it seems like all manuals don't have one...only auto...but that's just a guess...don't quote me on this...

i said the above cuz there was a debate that all non-SE models came with a speed limiter(what a load of manure)...then it turned out that Kev's car had one, and more SE auto people came out complaining their car hit the limiter..so, my guess is that it's not the trim level, but it's ur tranny that determines how fast u can go..

 

i wonder what kind of ride when car is equipped in 17's...

 

it gets a little stiffer(lower profile tires) and little bit noiser(depends on what kinds of tires u use)..
but it handles better.

 

My max is a 5-speed and it does have the damn limiter. The fun police kick in at 135 every time. I can cruise at 134 but if I go for 135 it is like someone shuts of the ignition.

One possible explanation as to why some have one and some don't is what tires the car came from the factory with. Mine has the sucky 15 inch steel rims and "H" rated tires. It is possible that cars with 16 inch tires and wheels do not come with a limiter. Just a theory but it would make sense. Could also have something to do with the build date. I bought my car in late 2000 after the 2001's were already released. Had to cash in on the rebate since the car had not changed from 00 - 01. Again all are possible but who really knows.

 

No. You're exactly right. The speed limiter is put on because of the tires the car came with from the factory.
