370cc injectors

I'm gonna run the 3.25 pulley with moded auto on my 5th gen(v2)...you think 370cc injectors are enough? To much? Anybody have anything else to say? Any company suggestions would be helpfull to.
Thanks

your stock injectors can handle that pulley no problem.. but if you do get the 370cc injectors.. what are you going to do to lean out the fuel?

So you don't think I should change them at all?

Using different injectors required ecu changes that may/may not be available. There are others that are using smaller/same pulley sizes and pulling alot more hp. You just have to RESEARCH and find out what they did. There is a thread that is very,very specific on this. You just have to find it.

Tai Mai Shu Jr.: no need for coments like that.

Jeff92se: I am doing the ecu. Thats one of the reasons I asked this. I also did search and found alot but not really enough specifics like this.

SprintMax: The tranny is giong to be completly rebuilt. Think thats enough Also I just want everything to run optimumly so I thought changeing the injecters would squeeze out a few more ponies

if you are getting an ecu done.. then hey.. why not go for the injectors too.. JWT has injectors .. http://www.jimwolftechnology.com

might want to invest in a new fuel pump too.. if you have not already done so..

do a search JET does a modified ECU for the 2000 maxima.. just tell them what you need and they will do it.. takes a day

Let me know what you find out about the injectors. Once I get everything sorted out, I want to find out just how much power a maxima motor can take with enough fuel. I'm already taking care of the drivetrain with an upgraded tranny, prototype LSD, and prototype axles, so I want to see just how far the VQ will go. Plus I have a hookup on any injectors I need, so cost isn't an issue, I just want it to work. I tried Don, but he's too busy to answer emails right now.

Why not find a wrecked Max and bench test the VQ? This would be much cheaper than ruining your awesome ride Shadow. Don't flame me anyone, just an idea.

now now.. JET does great reprogramming.. its their add on chip that has problems.. the reprograming is the samethign JWT and UPRD does.. changing the air/fuel and ignition mappings.. nothing special..

Went from not knowing there was one for the 2k max to not liking it????????

Why not jet. Some says it works some say no. But they do have a good rep and even if it gets no power (kinda odd) If it does change everytyhing else thats worth it.

No, no. I'm not going to destroy the engine, I just want to find out how much power I can have safely. That's all. I've talked to a lot of people who know about these things, and they've given me some hpnumbers to aim for. I've done so much show stuff, I want some performance now. And you know how I like to push things. But it's not going to be done stupidly, trust me, a lot of dyno tuning will be involved. I just want as much power as possible.

the JET CHIP the add on chip to the ECU is the one with no gain.. the reprogramming of the ECU is a different story..

pump.. not sure if the pump we use will work for the 5th Gen.. but i would get a high pressure pump.. just to be on the safe side.. not sure if the stock pump is that good.. well thats just to be on the safe side.. i maybe wrong.. and it wouldn't be the first time

So JET can reprogram Maxima 97+ including the newer 2000 maxima?

Ok, good to hear Shadow, don't want you destroying your pimp ride. Oh, by the way, how are the Type II's doing? Any word yet?

Wow so much proof! hehe. Where are you on that? Just make sure you don't get just a sticker. I thought the later ecus needed a totally new daughter board in order to work? What makes you believe JET can do something for us?

well all they have to do is reprogram the mappings.. i didn't get it because they can't do the daughter board like JWT to keep me from detonating while on Nitrous.. so i didn't do it..

Well according to others, there are like 4-5 different ecus for various maximas so they would have to be able to do all of them. Plus I thought wjt and uprd had to get Nissan daughter boards for even na mods. Nissan ecu codes aren't the easiest to crack so I hear. So JET can do this? Why not ask JET to repogram the na 1997+ maximas? They would make a killing. I haven't seen any good dyno info on them though

N/A Z injectors are 330, and should work great for what you're doing. turbo Z injectors are ??? cc/min, but they'll also work.. just plug a number into the ECU and you're set.

you can usually pick 'em up used at a junkyard for under $200/set.

well i was going to be the test dummy.. but matt strongly advised against it because i was running Nitrous.. they say they will do it for $399.. aparently no one knows about it.. only one person i know with it is not on the board..

Would an adjustable fuel pressure regulator work? He can decrease the fuel pressure, but would have to spent few hours on the dyno.

You could but that would be a crude way of getting the cold start and part throttle setting back to normal. And then there's the problem of how to get the fuel pressue back up when the boost hits. As far as I know there isn't a FPR that can do both decrease and increase fuel pressures based on vacuum/boost conditions.

Just tune the FPR at WOT for the SC, it will be rich for part throttle. No biggie..bad emission and wasting gas shouldn't be an issue

I don't know. Offhand, I would say fouled plugs and crappy part throttle accerlation would be a result. There is a better way for his set up though

hey

juss wanted to inject some of my input into this. remmeber injectors for a 4th gen and 5th gen are different. For a 5th gen you have much more choices while 4th you prolly only have the 300ZXTT injectors as an option.
