Looks like its between a Zex system or Nitrous Express? I like NX throttle positions switch, which allows the nitrous into the motor only between a set rpm range when the switch is on. Plus the fuel pressure switch which switches the nitrous off when fuel pressure drops. Whichever system I decide on I'll definitely install the following two or four-degree cooler plugs, bottle heater, purge kit, blow valve and tube, remote bottle opener, and pressure gauges at the bottle and remotely on the a-pillar. Also I will probably install some type of inline fuel pump helper (ZEX) and a spark enhancer (MSD) just to be safe and have a backup. I already have a high flow no cat exhaust system and custom plug wires. I'm only on planning running a 35 shot to be safe at first. The next question to answer is single nozzle wet or dry or direct port injection? All above for use on 99 Protégé manual transmissions. I'd like to keep material cost under $1500.00, I'll do the installation myself to save on labor.
Thanks for the ideas and suggestions,
Dave

 

Under $1500 huh? You would be shocked how fast you can go for that amount of money. That's about half of what a good turbo kit would run you and you would still be faster!

You always start with the smallest jetting unless you know what your doing. I start at 50hp, but that's me and I have done alot of cars before.

Without getting techincal or using any bias, I'll let you decide for yourself. Simply put -

The job of a nitrous nozzle is to atomize fuel and nitrous together.

Some companies do this better than others. NX just happens to be the very best at it.

The reason why NOS came up with it's dry manifold system was MAINLY because their 1st and 2nd generation nozzles didn't atomize the fuel/nitrous mixture well enough and caused fuel puddling in SOME engine, not all. This would cause a backfire though the intake and results in a hole or many small parts depending on what your intake manifold was made out of.

NOS is soley the most popular nitrous system because of marketing. Open up any major automotive performance magazine and what do you see? A brightly colored ad which by the way isn't cheap to put in national magazines. I know this from trying to promote my business myself without the needed funding.

ZEX's nitrous system is based on NOS dry manifold technology. They just cut down on installation time by mounting the regulator and TPS control unit inside one case.

Edelbrock's JG Dry kit were designed by the same guy that made NOS' dry kits. He has since moved on...

Anyway enough of that. Price is also important right?

Nitrous Express will be the best money spent on performance for your car, period end of story.

If you wanna kick some major booty, copy this or print this out -

Nitrous Express Mazda EFI single nozzle kit

Nitrous Express GENX2 upgrade (purge,bottle heater,gauge,etc)

Nitrous Express Remote Bottle Opener

Nitrous Express "Freddie" Progressive nitrous controller

15lbs bottle upgrade

100hp jet upgrade

MSD "Windows" RPM switch

You only need 1-2 ranges colder plugs! Not 4.. Autolites and NGK's work very well and are much cheaper than ZEX's plugs.

The Progressive controller will be your "unfair" advantage on the street and allow you to use more nitrous more effectively. Trust me, when you install this and set it correctly, you wonder why more people don't have one. While everybody else stuggles for traction, you'll be half way down the street/track...

This IS the best nitrous system you can buy, period. You don't need any fancy computer monitors, just common sense. For what your getting the Venom is over-priced and you have just as much control here.

Total Cost? $1300-1400

Of course you'll start at 35hp, that's the smallest setting. But with full bottle pressure, I wouldn't be shocked if you picked up as much as 40-45hp with the 35hp jetting!

thanks for the ingo anthony ,, you just opened my eyes wide lol

Anthony,
Thanks a ton for the info. I've been heavy considering Nitrous Express since I first had the idea of running N2O. Now I'm sure, a NX system with everything that you suggested. What is the part number of the Nitrous Express Mazda EFI single nozzle kit? Or should I just call up nitrous warehouse and let them give me the hook up?
Now if I could just confirm that a Mazda Miata (year?) flywheel is the same as the one in a 99' Protégé manual trans? I’ve been waiting on Indigo to make one for a while now with no luck. Along with a stage 1 clutch I'd have one fast mother of a Protégé. I’ve completed all kinds of suspension, traction, control, and safety work on the car.
I'd do the custom turbo but nobody in my area will touch it. And that’s a project I'd rather leave to some with more experience than I. And by the time one is available as a kit I’ll probably have blown my 1.6er and swapped it with a 2.0L.
Again thanks for all the help. I’ll probably call on ya again when it comes time to installation but it looks pretty straightforward. I’ve run N20 on both an 87 Toyota truck and a VW.
Thanks

 

If you have installed nitrous before this isn't any harder, just more stuff! It will take you longer, but you can still do it in a day.

That's another reason I suggested the Progressive controller. It will allow you to use more nitrous on the stock clutch.

If your clutch will hold 50hp, it will hold 100hp with a progressive controller.

Trust me, you won't need much more than 75hp to kick most people's asses. I would use 100hp or more for the heavy iron..

If you spend an extra $100, you can get the fully programable controller, install your 100hp jets and set your final nitrous flow at 50-60%. Need more? reach in the glove box, called up one of your ten settings and bling, bling another 30-40% power increase....

If you get the full kit, man.... You have no idea. Making this much horsepower is almost too easy.

As for a turbo system. Doesn't a manifold from a BP series engine fit? If not a custom one shouldn't be that hard to make. It would cost around $400.

A good street turbo would be a T28 with a larger turbine wheel. That why you have quick spool up and have enough flow for about 270-280hp. Inovative can set you up for about $700.

Couldn't you use the LINKsystem replacement ECU for fuel and ignition control?

Turbocharging isn't hard either...

Oh yeah.. yes Call www.nitrouswarehouse.com, order everything or part of everything I told you and they will be more than happy to answer any of your questions. My buddy's kit was just shipped out Friday..

 

Only prob with a wet kit on the newer protege 1.8 and 2.0L is the way the intake maifold runs fuel puddling is a problem unless you go direct port with is the safest N2O method by far in my opinion I am running a 50 shot along with my turbo and it runs fine and I love it!

 

Eeeee. wrong, Puddling only happen with NOS' 1st and 2nd gen Fogger nozzles. To prevent puddling you had to move the nozzle as far back at 8-10 inches from the throttle body. The problem was that those nozzles didn't atomize like they should have. It took NOS' 4 years to come up with a nozzle they would consider selling in a single nozzle kit (90 degree soft plume). But why do that when you have the public snow-balled into thinking that DRY are the safest way to go?

I have run Nitrous Express in many cars, along with a few The Nitrous Works and Top Gun. The worst thing that has ever happen to me personally was a burnt clutch...

I have known two cases of the nitrous solnoid "sticking" open and causing a nitrous backfire through the intake. NX has since fixed that problem and warranties their solnoids for 2 years if memory serves me. That shows you how often I had to send them back (never..).

In any case, dry is okay, but not the best way of doing things are you're always limited in output to about 80% duty cycle on your injectors, which in a Protege should be right around 70hp.

NX kits from NW cost less than any dry kit available brand new, you make more torque, make more horsepower and have one of the best atomizing nozzles you can buy. NX are so good, they hit just as hard at your throttle body as they do 10" back from it...

Since you have a dry kit, I would check out Crane's Digital Nitrous Controller. Very slick unit, in fact I like it better than Venom's VCN-2000 progressive/linear program.

Seriously, put that thing on and your ET's will drop like a rock. You can also dial-in more horsepower as the RPM go up. Nitrous in itself is dumb, progressive controllers make it very smart...

 

OK, here's my question....

After we installed the ZEX kit we learned very quickly that we needed to upgrade the spark plugs. We bought a set of the ZEX plugs and everything seems to be running alot better. I have heard from a few people that we should upgrade the spark plug wires, do you guys know how much this really helps?? If you think it would make a big different which brand would you recommend. Has anyone used the Magnecor 8.5 mm wires?? I just really want to know if it will help the performance and save the engine in the long run.

 

for the most part, people will tell you no, plug wires don't make a big difference. it may or may not deliver the spark better. no ones really tested it. the zex kit tells you to run colder plugs in the instructions. :| i like the denso iridiums i bought (even though a bit pricey) for two ranges colder. if you feel you want to be on the safe side for the wires... go for it, get em.

 

Denso's are pointless and over priced, just get a set of maybe 1 or 2 range colder NGKs

I have NX, and HAVE NOT had any problems with it.

I know MANY people with NX Wet kits that have been running them for at least a year, no problems, one guy has a 75 shot on his D16 SOHC Civic, never had a problem

if you think about it a NX Wet Kit will be safer, Fuel and N20 going into the engine mixing with Air and more Fuel. No Wet shot = N20 alone going in with Air to mix with Fuel, uuhhhh.

I was running a 50 shot, (I resintalled it myself, PIECE OF ******* CAKE! cant believe i payed 200 for this ****) as of yesterday im running a 75, and MAN felt like my car automatically hit a new gear or something, with NX you can more than feel the difference in power from a 50 to a 75. I'll go get it dynoed for yall this weekend .

oh and Anthony Thomas, we have Coil Packs, not plus wires. in the Protegés, , theyre good for 400 hp.
