Has anyone installed a NITROUS EXPESS 20923 Stage 1 EFI Kit?

THis is a wet kit for u newbies...

I own a 2002 mazda protege5 2.0L engine
With a intake and aerospeed muffle w/ cusom axel back piping.

If i run a 35 shot will i wind up w/ problems down the road?

My car has only 18000 miles!

thanks

there's always a chance you will end up with problems. If the kit isn't installed right it could break somethin. Also if you spray all the time you'll put alot of stress on the engine.

If you want to run NOS, even a 35 shot, be prepared for some problems. You may end up being one of those people that dont have any trouble, but I wouldn't count on it. Just about any form of FI or NOS has its drawbacks, but if built properly an engine can handle about anything you can throw at it...... trannys are a different story....

What i have really noticed from being in this forum...is that most people who blow their engines using Nitrous:

1. Driving a MP3! which as everyone knows the advanced timing is the problem!

2. The Run Tooo Large of a shot of Nitrous on a stock setup!
-or spraying alot over a period of time!

3. Use the wrong set of plugs(platinum) and wrong gapping!

4. Using cheap fuel (89) instead of 91 octane!

Any juicers have any suggestions for me to keep my car running in good shape while i am squeezing????

Please HelP!!!!!

That's a classic case of people not following directions...

Advanced timing is not an issue. Just increase the octance rating of your fuel. You can use a good booster like NOS' Racing Formula or find a local gas station or speed shop that has 100 octane unleaded and mix a couple of gallons in with your 91-93 octane.

Using higher octane is a better option that using ignition retard.

Never use Platinum plugs with nitrous! Platinums were designed with long term durability, not excessive heat generated by using nitrous oxide. Contary to popular thought, Platinum plugs are NOT performance plugs. All racing engines use a standard plug...

Running a 25hp shot will cause as many problems as a 50hp shot, if the directions are not followed.

First I would suggest with any kit you buy, get a bottle heater. Not only will it help maintain top performance with nitrous, it also keep the bottle temp in the right range for the correct fuel mixture (900-1100psi).

Any engine in good running condition car use up to a 50% HP increase without any long term issues. So on the Protege that would seem to be about 65hp, but using a slightly larger nitrous jet to get 75hp (only 10hp) is NOT a big deal at all.

For 50-75hp, I would suggest investing in better tires or slicks if you can afford them. People forget that your not only adding 50hp, but about 70-100ft of torque also, which leads to traction problems. I would also upgrade the exhaust system, since most factory exhaust systems are marginal to start with and will quickly be the cause of some serious backpressure when you increase the power from about 110hp at the wheels to around 180-190hp.

A 50hp shot will knockoff at least a second, but more is possible if you address the traction problem. I've seen almost a 1.5 drop in ET from a 50hp with slicks or drag radials and an additional 1-2 tenths from a free-flowing exhaust system used with nitrous.

Feel free to e-mail me with any other nitrous related questions..

I am having someone proffesionally install it...

I have already worked on my exhaust and intake

right now i am running a reactive warm air intake..

and for exhaust i have an aerospeed exhaust axel back

i believe our protege's are 2.5" for exhaust. or maybe that's the mp3?

well..anywayz...what is a good spark plug to use?
I heard NGK's are good...

also...what do u mean by a 2 deegres cooler?

If i picked up a set of spakco wires do u think it would help?

Also what's ur email adress?

For octane...the best around me is 91octane

so could i just add octane booster to the mixture?

Save your money and do it yourself, you might learn something.

Intake is not an issue. You'll run the same times on nitrous with teh stock air box in place. As for your exhaust, 2.25" is the MP3's exhaust. I would guess the standard is 2.0". With a 50hp shot, it will be fine. However with a 75hp shot, you might loose a little power overall. Nothing you will notice, but something you can see on a dyno.

See above

Same thing

Again..

NGK's are fine. They cost a bit more, but they work fine. So do Autolites.

You'll want to run a spark plug one range colder than stock. But usually stock plugs are just fine. You can use a "colder" plug but it's your choice.

Better wires would help, as the factory gives you the cheapest plug wires they can find.

Well, I believe P5's are rated for 87 octane. So just moving up to 93 pump is more than enough. A booster isn't needed

I am worried about installing it myself....

I am very new to nitrous...but you are correct...i should do it myslef....

about the plugs being one range colder...the auto store will know what i mean?

also...can you explain the wet kit to me...

I heard the difference..is that the shot of nitrous is added w/ the fuel lines..and shot in that way...so that you won't lean out...

is that true...or am i missing something?

thanks

Yes your correct about how a wet system works. A dry system uses your OEM fuel injection system to provide the extra fuel needed or enrichment. One side of the nozzle is marked fuel and the other is marked nitrous. The nozzle then mixes to two together into a "fog" dense enough to not allow puddling.

That was, and I stress WAS a major problem with NOS' first and second gen Fogger nozzles. That's why they developed a dry injection system, because they thought with all the new intake designs that was the route to take, but if you notice only two or three other companies make dry nitrous kits. The others solved the problem at the nozzle and haven't looked back.

Without getting too indepth, let's just say going with NX isn't a bad idea. Other kits that use simular nozzle designs are Top Gun, The Nitrous Works and Edelbrock. NOS' "Soft Plume" nozzle is just like NX's and the others and is offered in NOS' new Universal wet nitrous kits.

You also need torque with an automatic transmission, so going with a wet kit is another good reason. Wet kits produce more torque because your adding fuel at the nozzle and at the injectors, not just at the injector like with a dry kit.

Yes a good auto parts store can help you with plug selection. Look into your owners manual. It should tell you what your OEM spark plugs are and their gap. If it's larger than .035 then you need to regap your plugs, as a gap too wide might lead to a misfire and poor performance.

Again as for installing, there's enough information, tech numbers and web sites not to mess it up. NX's directions are layed out pretty well.

did you get it put in yet?
