Plans for nitrous
 

I've been debating for awhile whether to do heads or nitrous.. and after comparing dollar for dollar and the gains, I'm going with a NX EFI Plate Kit.

I actually plan to spend quite a bit of money. First off, here's what I want..

NX EFI Plate System
GenX-2 Kit
NX RPM Window Switch
NX Remote Bottle Opener
and probably the 3 position switch by AM.

I'm thinking the highest shot I'm going to be able to run safely (I will have a nitrous tune on the dyno) is going to be 100. Obviously I'm going to need a few other upgrades to go with the extra power.

Fuel pump? What should I go with... is the focus fuel pump the best option? What other things will I need with this fuel pump to install it?

Injector sizes?

Spark plugs?

Anything else?

As always.. me and my dad will be installing. Anything else to make the install go easier?

Btw.. I'm not doing this until probably the spring, slicks and skinnies come first :D

First off shop around for kits there tons out there.

You dont need the bottle opner either. Just mount it at the back of the rear seat like i had to (mach1000) and you open it yourself from the drivers seat, saved you 200bucks.

The SVT focus pump is all you need, hell the stock one works fine at 100hp but a focus pump will help make the lean spike not so bad. PLus randy sells them for $93 shipped to your door (it was a year or so ago when i got mine) its just a simple drop the driveside of the tank, open the top pull the cover off and remove old pump and install new. Even the connections are the same so no splicing needed, Yeaaaa.

You need a one step colder plug, i have always used NGK TR6's they are cheap and are copper and work well. Part number 4177 at any store that carries them.

Your injectors dont change as the nitrous kit will add the extra fuel for you.

Since your a manual get a MSD window switch (trust me) you will enjoy it. I can powershift threw the gears on the bottle.

I will say this also, i hated my FPSS i got rid of it and have a FP guage instead. So thats up to you but me i think they suck.

Other then that. I love nitrous and so will you. and dont worry that 100 will turn into a 125 or a 150 one day.

Oh and plan to upgrade that clucth cause with all your mods and a 100shot your car is goiong to make some nice power (i see a spec stage 2 in your future).

how do you think those plugs will effect my N/A performance?

Also, how does the msd windows switch differ from the nx window switch?

thanks :)

i am a nitrous noobie

Not one bit. I have been using them for over 5 years. Only thing is that when the car is cold it can be weird for a min or two. Thats it. But only on cold days once the plugs get some heat its the same as always. And thats only right after start up for a few secs when you hit the gas. could just be my car though.

Lincoln Aviator fuel pump flows more. The focus svt pump is maxed out at around 425rwhp give or take. The lincoln gives you more room to expand since you are swapping anyways. Another choice is the Ford GT fuel pump. They are all pretty close in price to the focus for more flow.

The MSD one is a fully digital one that all you do is wire ti up no tach adaptors needed. and you set the rpms with buttons not pills.

The NX one also made by MSD is the old pill style that requires a tach adaptor. Get the MSD digital one. there is one on www.fuelslut.net for 80bucks right now in the for sale section.

As for the pump while the aviator flows more its more money and you really dont need it. Also i dont know if you know this or not but the pump upgrade WONT require a retune by itself. so feel free to grab one and install it ahead time if you wish. The ECU will varry the voltage just like the stock pump to keep the correct fuel psi.

Oh and for the bottle be sure you look to see where you drill so you dont drill the tank or lines, and use a large washer on the bottom to help keep the bolts from being ripped out. if you are ever in an accident you wouldnt want the bottle to fly forward and kill you.

Thats all i can think of right now, hope i helped you out.

Heres' my 2 cents...

1. Spike has it all lined out for you. All good info there Spike:worship2: I agree that the FPSS is a waste of $ on a returnless fuel system.....save your money.

2. The Aviator pump does in fact flow slightly more, but cost about double what the Focus pump does. Once again save your money , you don't need it.

3. I just ran 12.73 @ 105 N/A with TR-6's gapped at .035...so no problems runnign N/A:breakdancesmilie:

4. With those cams stay with the 100 shot

5. Traction will be your biggest problem....keep this in mind:shakeno:

If you think youll run nitrous for awhile and stick with it. Then Id go ahead and get a direct port system with a fuel cell. This is the kit Im looking at right now, http://nitrousoutlet.com/catalog/pro...product_id=367 I wish I had gotten that in the first place. Eventually Im hoping to run that kit, with this fuel cell, http://forums.modulardepot.com/showthread.php?t=83036 Im also planning on a short block similar to the MMR Mod 900 with all ARP stuff. But my block will probably be built by Steen Racing along with their heads and my VT stage 2 cams. And a built 4R70W by BC Automotive. All of this wont happen for years, but I like planning ahead.

The NX EFI Stage 1 Nozzle and Plate kits can spray a 200 shot. However, our cars cant really handle that amount through a nozzle. I actually wouldnt go over 150 on our cars even with ported heads and aftermarket intakes.

Just make sure you think this out and plan for the future.

Yeah.. I'm going back to my original idea of 26x10's for the slicks

I thought those direct port systems were a little too harsh on stock bottom ends? I won't be upgrading my internals for awhile

You can run a 100 shot through that direct port.

Remember those plate kits have pretty bad lean spikes. So Id say the focus pump is a must, and you might want to get a longer nitrous line from the nitrous solenoid to the nozzle. On that fuel cell link I posted, DadsYellowGT got that fuel cell made because he couldnt find another way to cure the plate kits lean spike.

26x10's will cover the traction issue:breakdancesmilie: Direct port systems have their own problems...keep it simple....NX is as good as it gets:boink:

Educate me please. Im just starting to research this option.

Also, make sure you gap those plugs to .030, not .035.

I also have to agree with this direct port just isn't the greatest route more chances for mechanical failure/blockage. Keep it simple...Last time I heard of problems with direct port systems is that they cause lean conditions due to poor fuel distribution to each cylender. And if you know what this means its going to throw off the computer and screw up all aspects of the fuel distribution. I know someone now that even after buying a new built motor put on a holley direct port system. Now is having issues and has to sell her car due to insufficient funds to fix.

Guess Ill have to keep researching. Its not going to happen for awhile either way.

Good info guys,

how about some info about installation?

You're kidding me right? Pretty much the same thing, just a plate instead of a nozzle. http://www.dndgarage.net/nxinstall.htm

Thats a walk in the park after reading a little bit. Just keep the wiring clean and neat and you'll be good to go.

sweet, I'm inexperienced when it comes to nitrous, but I've heard install isn't bad with plate kits. :D

Oh yeah, what about the lean spikes from plate kits? Does the new fuel pump and tune pretty much take care of that blowing your engine up? lol

I've heard mixed reviews of the plate kit....some people had issues with a lean spike and some had issues with the plate with the fuel not being evenly distributed or something like that. Something some of the other guys can fill in on.

Oh and the fuel pump dont think its going to push out fuel harder think of it as protection against running out of fuel to the motor. The focus fuel pump will be able to keep up with anything you'll be throwing at the motor.

The plate kit jus thas a nasty lean spike thats way worse then the regual fogger nozzle that is normaly used. Skip the plate kit get a regualr fogger nozzle setup and spray the shit out of it. No tune will fix the lean spike, they can try to help bring it down some thats it.

As for install, like i said about the bottle do that. And I ran my nitrous line under the car from the back as it was easier to drill the hole and run it with the other lines under the car and zip tie it out of the way. For wiring well its not bad at all. I can give you a little wiring diagram if you want.

i saw your post on another board about the new n/a best. Thats a kick ass time man congrats.

hmm.. ok


any recommendations for gauges?

fuel pressure, nitrous pressure, oil pressure, egt. In that order.

why is fuel pressure more important than knowing oil pressure? just curious, i thought oil was more important, but im a newbie

As far as nitrous goes. I'd go oil pressure and nitrous pressure no order of importance. A FPSS will save the motor if fuel pressure drops. EGT is almost pointless at this point.

And I saw it stated earlier and I think I should reinstate that a focus fuel pump or any fuel pump for that matter will not help with the lean spike issue. It's simply a mechanical limitation of a returnless style fuel system. The computer can only react once it realizes that the fuel rails are sucked dry from the activated fuel solenoid, and up the voltage to the pump to supply more fuel.

well I plan to go with the nozzle system now, getting the svt focus fuel pump, and a dyno tune. sound good?

True and not true, the higher flowing pumps recover faster from the inital hit then stock one.

you need a Fuel pressure guage if you arent going to run a FPSS (i said how i feel about them). and a nitrous pressure so you know the pressure the bottle has and when its getting low.

Oil pressure is just a good guage to have in general as well its kind of important for the life of your motor.

I don't see why they would. Could you explain that in more detail to me? I don't see how a higher flowing fuel pump will react quicker to fuel demands when the computer is what tells the pump when the added demand happens?
