WELL IM A NEWBIE FROM NYC I GOT A 2001 SE AND I WAS WONDERING IF THERE IS A PROGRAM THAT IS OUT IN THE MARKET THAT I CAN BUY TO REPROGRAM MY ECU... ???? HOPEFULLY THERE IS SOMETHING OUT THERE

 

there is the Jet chip, which is an ECu piggy back. However, some say it doesn't do anything, while others say it does. There is no clear judgement on it either way. Instead of ECU, save your money and get intake/exhaust first.....


BTW, caps off please

 

Doesn't the Jet Chip just remove the rev limiter and speed limiter and adjust the fuel/air ratios??

 

It also changes the shift points a little,and if you have some good mods going then adjusting the air/fuel mixture could be big. Basically it's not a mod just for doing a mod it's self. It's a mod that improves and makes all the other mods work better together and optimum efficently...or at least it's suposed to.

 

so in other words before i get the ecu upgrade im better off upgrading the rest of the car first...thanx alot fellas
sory about the caps

 

yes... get intake/y-pipe first.... SC maybe?

 

Yeh and on another note, little mods like y pipe, intake,exhaust and all will make a diff, but a little diff. If you did everything but a supercharger that you could do you'd spend around 3k and gain around 40-50 hp...but for a little more on a supercharger meaning 3700 you could have 80 hp more. Looking at a price per hp look i think it's better to save up and just get the supercharger. Plus if 80hp ain't enough you get a 50 buck pulley and get more power. Can't beat that.(nobody mention turbo's).

 

but if i decide to get a SC is it just a bolt on or do i have to do other mods before i SC it

 

Depends, if you have a 5 speed you can bolt the sc right on along with the other fuel devices that come with it. however at some point its good to upgrade the clutch flywheel and do a short shift kit.

If you have an auto to help not kill the tranny up front it's good to have a tranny cooler and vb mod. The valve body mod goes for between 400-700 depending where you send it.

 

Are you referring to $3k worth of engine mods? I have intake, y-pipe, and UDP and it all cost less than $1k. I know there's further exhaust mods I can do, but I don't see them adding up to more than $500-700. Am I missing a good mod somewhere? As far as best bang for the buck goes...how about a 75 shot of nitrous? Less than $1k for a good kit, and 75hp without the constant wear and tear on the engine (provided you can stay off the stuff some times). It's just a little more volatile for your engine than a s/c.

 

However, a supercharger will void the warranty without any doubt for all kinds of engine and tranny problems, while the classic NA mods (intake, exhaust, y-pipe, etc.) will have a much less chance of causing grief at the dealership if the car develops problems.

I assume this would matter based on you having a 2001 Maxima.

 

The numbers are just an idea to get see what gives what numbers for what price and so fourth. But to get the power a supercharger can give you look at these things:
Full exhaust (headers, y pipe, b pipe, cats, muffler prob around 1500 w/ 25hp
CAI 400 w 7hp
camshafts 600 w/15hp
port and polish Im not sure but like 1g possibly 10-20hp
You can see where i'm going
One mod s/c 4gs but 80 hp from stock less down time.

Nitrous yeah but it is harder on the engine than a s/c mostly cuz so many people do it at wrong times. Plus you gotta say "hang on let me get my bottle filled" who wants that crap.

Yes the s/c will void the warrenty's but try to have some of the stuff replaced anyway and watch them not want to warrenty it. Plus if you wait for the warrenty to expire thats a bad time to do it you gotta put the s/c on when the engine is newer so it don't already have alot of wear and tear.
A few precousins and taking care of the car a s/c will not hurt much if everything is maintained and watched over and hooked up right

 

There's camshafts out there for us? That might be a good idea for the next mod...where do you find those?

 

I think the 300zx cams fit. Maybe that was only the last gen max's. But you could mod the factory ones. still be the same effect.

 

Where would you go to get that done? A machine shop or something to that sorts? I know nothing about some of this stuff....

 

I'm not prolific with it but yeah I think you can take it to engine rebuilders and they can do it easy.

 

"""Full exhaust (headers, y pipe, b pipe, cats, muffler prob around 1500 w/ 25hp"""

Headers have proven not to give much if anything. The rest might give you 15 hp(flywheel)

""CAI 400 w 7hp""

Sounds about right. $400? Not that much.

""camshafts 600 w/15hp""

What cams?? None are availabe. 300z is a completely different engine.


""port and polish Im not sure but like 1g possibly 10-20hp""

Probably not. We are not dealing w/ old muscle car pushrod heads w/ massive casting flash and crappy port design. If the machine shop doesn't know what they are doing, you will probably lose power. Gains might be 10hp max. And only with altered ignition/fuel maps(currently not available for 5-gens)

SC. Proven, proven hp for the money. A long way from the above theory mods.
