One of the guys at Stillen was telling me that if I want to run N20, i need to diss the JWT ECU and put the stock one back in. what do you guys with N20 think? Are you running the stock ECU when you run your wet kits?

 

N20 and advanced timing is not good. You could run a small shot with the stock ecu. Or send the ecu back to JWT for a reprogram and a daughterboard addition for the nitrous

 

too much money............i already looked into that. I wanna put a 100 shot in and my question would be: can I run a 100 shot with the stock ECU?

 

No one is holding a gun to your head nor is it physically impossible to hook up everything. So you can do it.

IMHO. If you want to run a big 100 shot, you had better not skimp on the supporting equipment. You're pretty much guaranteed to blow the motor up. Just a matter of when.

 

yes i agree with jeff92se u cant run a 100 shot on ur se with out proper fule manegment and timing retard and secondly u might even need block guard remember the ve has an aluminum block unlike the vg wich uses a cast iron block be safe not sorry :P

 

Whatcho talking about Willis?? VE30DE uses an iron block. Not that makes any difference as his pistons/rods would turn to soup before the block goes. heh

 

O.o ve dosent use aluminumblock/heads i thought it did :\
and i thought the vg used ironblock/ alumn heads most dohc motors use aluminum blocks i thought i guess im misstaken

 

Going off what Jeff said, I wouldn't run the 100 shot off a JWT no matter how much fuel your adding to the motor. If you need a spare VE auto ECU I have one but it sounds like you have one too. You could probably safely run a 35 shot or so with the JWT, but I dont think anyone ever has (well with the tune you have). Might just want to be safe and put the stocker back in.

SR20DEN ran a 125 shot on his car for a long **** time and never had a problem with reliablity. Yes it's a different engine, however we can look at the Z32 and see how they are responding as our engines are similiar. I would be more concerned with your tranny. I forget, do you have the Valve Body mod?

Another thing, I would start out with a smaller shot and work your way up. not soo much for the car, but also learning what it will feel like with the additional power.

 

If you want, I'll trade you my spare VE 5-speed stock ECU for the JWT

 

beat me to it, LOL

 

If you want to run a big shot of n2o I suggest using a progressive controller. I have the JWT n2o program so all you need is a dry kit and it alters the timing/fuel curves. Something like the NX maximizer would rock for a 100 shot.

 

I was already opening that door with my ECU suggestion

 

Why? Because you think JWT's program is crap? If that is your implication, and that's what you are implying, state the reason(s). Why can he run a 35 JWT shot and not a 100 JWT shot?(not counting the actual engine strength) What's the difference inbetween the programs for the 35 vs 100 besides the obvious timing and fuel maps?

 

guys guys,.......according to Ben at JWT, they only make a tune to run a 65 dry shot........nothing more, nothing less. I know I am going to have to get a bigger fuel pump (walboro fuel pump) NGK copper plugs, and a fuel pressure regulator. If the N20 wet kits are run the right way, IT IS TOTALLY SAFE AND RELIABLE. i know this already from witnessing it on other cars (mainly V8's). In the meantime, I need to know if the stock tune on our maximas from the factory, are good enough to run a 75 or 100 shot.
Acccording to one of the guys at Stillen, it is. I don't really trust this guy though, and I don't think he knows what he is talking about.
So I'm going to have to go out and do my own research: with you guys.

 

I wouldn't trust a Stillen salesmen any further than I could throw him down the street. So as previously suggested, work you way up with small shots. I know a guy that ran a 100 shot but I don't know the setup.

I wouldn't actually go as far to say a 75-100 shot is totally safe because you saw it done on a V8. Apples to oranges comparison.

 

The N20 program that JWT makes is only good enough for a 65 dry shot, am I correct? And it utilizes the stock injectors and fuel pump. Kinda risking it if you ask me.
Does NX make an appilcation for the VE's or are they all the same?

 

just as an idea, the stock vg bottom end should handle about 300-350 hp. having a cast bottom end makes it a bit harder to tell how much power it will handle but that's gerenally the number that floats around when talking about the vg power capabilities.

i'm not sure on the ve, but if it has a forged bottom end then it should handle quite a bit more. there's probably a bit more to it than that when dealing with nitrous so i'll let the people who know nitrous continue on from there.

 

I believe you have to consider the strength of the rods (pretty strong from what I gather) and the strength of the pistons (maybe not that strong) Especially if it ran into a lean condition.

 

I have been seriously considering adding nitrous to my VE Auto. So, for the past year or more, I've been doing quite a bit of research.

I've always liked the route Jime has taken. 5ltrbeater, go to the nitrous section and read everything you can. Especially, anything that has to do with Jime.

My potential setup will have a basic NX wet kit. You won't strain your stock injectors or fuel pump b/c it's a wet kit. Next, remove that JWT ECU you have and put in your stock ECU. You need to make sure you don't detonate. With a 100 shot, I would go atleast 1 step colder plugs. Also, consider using 100+ octane gas if you plan on safely spraying that kind of a shot at the track. Since it's a wet kit, you won't have to worry about extra fuel since it's already provided. All you need to worry about is timing and detonation. Detonation is what is going to blow your motor. So, I would retard the stock base timing from 15 to something like 12 and then make sure you have colder plugs and high octane and be careful. Basically, what I am saying is, do more research. Read everything you possibly can on the internet about nitrous applications. Read everything you can in the forced induction and nitrous forums. Don't rush into this if you want to take care of your car.

Start with a 35 shot of NX and then slowly work your way up to 100.

 

As an addendum, do you think there would be any issues with fuel puddling in the VE 5-speed's variable intake with a wet kit? That's one worry I have about going to a wet kit sometime down the road. Otherwise, I agree in using an NX kit a la Jime.

 

I wouldn't run a 100 shot off of his current ECU program because of the timing advances. I do think he could run a 35 shot as long as he's smart about it. I thought I said that but I guess not. Either way I'm running late so I'll reread all this later.

Mizeree, highly highly unlikely, again i'll touch more on that later

 

This is where it gets confusing.

 

from what ive read the stock fuel pump will not support more than a 75 shot

 

I have never heard of fuel puddling in any Maxima unless the driver did something wrong. If you spray above 3K rpm at WOT, I don't see how fuel can possibly puddle to any extent. I have heard of some people spraying at idle on accident and some people spraying at WOT in 5th gear at 30mph!!! hehe I have never heard of anybody blowing up their car or motor unless they did something wrong. If you use nitrous like it's intended and be safe about it, the chances of blowing up your motor are slim.

 

I only ask because I have read that using a wet kit with a variable intake system poses extra risk because of the plate inside the manifold that directs the air down the two different paths. In theory, when you shift, the plate will change positions and could trap some fuel in the process, which then could be detonated. I know that when you shift and let off the gas the nitrous nozzle shuts off, but there is always lag in a system, and so some fuel will probably be in the manifold when the plate moves.

 

I am talking about his current ECU program, which for the sake of understanding, lets assume is the same as yours (minus the AT crap)

 

Oh. That's what I thought. Unfortunately, it's not what you wrote.

I'd just send the ecu back for a reprogram for a 65 shot I guess. $100 or so for a reprogram from what I read.

 

1. there is only 1 path, the VI just shares it, it in effect simulates shorter runners, but it really isnt *that* great, its not like that VQ35 pathy intake manifold, IIRC (I believe it has the true 2 runner design).

2. The plate stays in a vertical position until the solenoid allows the vacuum to pass. Assuming the automatic upper intake does not have the cutout like the 5spd does, when the plate closes, the VE VI essentially turns into the same design as the VE auto intake manifold (assuming the auto does not have a cutout like the 5spd, which I am pretty sure is the case).

 

It's not my fault you cant read my mind

 

Do you know if MSD makes an ignition retard switch that enables me to control the timing from inside my car instead of constantly having to retard it from outside the car. Again, i know they make them for mustangs and camaro's; but what about our beloved VE's?

 

i know the 300-350 hp is for the crank. the rods will handle it but the pistons i'm not so sure about. as long as there is no detonation they should be fine (just as any pistons) to a certain extent. i know that there is a Z31 guy running around or over 500 whp on the stock bottom end. i'm pretty sure he has different pistons though. i'm positive he has stock rods and crank. the block he's using is a pathfinder vg30e block but to my knowledge there is no difference between that and the maxima vg. i wouldn't personally try hitting those numbers unless i had lots of backup engines.

 

If you want to go big with n2o I'd suggest doing a setup simular to how Jime has his done. Or run a direct port setup do you wont' have to worry about puddling or anything like that. NOS and NX both make bolt on universal direct port kits without drilling. Remember with n2o a 100 shot at 4000rpm would produce the same torque gain as a 200 shot would at 8000rpm. The trick is to spray just enough to hook off the line and then up the shot during the 1/4 run.

 

yes, just look for one that works with a coil over plug design and supports 6 cylinders. I think their DIS system works but I haven't really looked too much.

You cant use the 6BTM's unless you get 6 of them, or get 3 of them and figure out how to set up a waste spark setup.

 

you guys rock!

 

is it possible to install nos w/ an automatic? and if so is it really bad for the tranns because of them being so weak , is it possible to strengthin the ban ds in the tranns or get aftermarket valvebody's?

 

 

the tranny wouldn't last too long with nitrous as they don't last too long with stock power, however you can get them built up to handle the power... you just have to dish out some money to do that. aaron seems to be the local auto guru (aaron92se). you might ask him about your options of building one up.

 

You can build up any tranny, pretty much. Search for NRH transmissions or check out www.maximumtuning.net. For $2500-3500, that should get you a nicely built auto tranny for the Maxima that can hold over 400fwhp.

 

hmm i think a fresh built ve with JE 87.5 high compression z32 nitrous ready pistons should handle a 100 shot. monday they will arrive.then machine shop for polishing of journals bore and honed then assembled and heads P&P. im gonna prob run a 75 shot zex maybe 100 on race day.

 

the stockers work with a 150 just fine so im sure the JEs will take 100 like its nothing
but youll get bored with a 100 i still have lost to a few bolton LS1s and spraying 5.0 mustangs
