Question for my Protégés?
Which N20 system for our Pros would you use or are you using?
I.E. NOS, ZEX, Nitrous Express, TNT? Wet or Dry system? What shot are you using? What type of control i.e. on at WOT only or with an RPM range set, or an arming switch that lets you use it whenever.? Any problems experienced in accelerated engine wear do to using the N20? Would you or do you use any ignition upgrades i.e. Cooler plugs, MSD spark enhancer etc?
Thanks

I'm running the NOS EFI kit and it runs great. A little complicated to install but well worth it. Not running anythign extra just teh NOS kit alone is all you need same if you got the ZEX kit. If you are looking for a kit with history behind it and great tech support go with NOS but if you want simple install go ZEX. DO NOT go Nitrous express as I have seen 3 guys here blow there engines with that kit from solenoids sticking.

I have the ZEX kit, mostly because I found a good deal in a group buy. I do like the simple install though, and the control unit uses the vacuum operated fuel pressure regulator to increase fuel pressure when nitrous is being used. Simpler than a wet setup, and just as effective for the levels I feel safe using on our stock engines.

I have a Zex kit. My engine is toast. I beleive it was the way I hooked it up(Vacuum lines). Make sure you do it right! It was fun blowin away Acura 3.2 TL's while it lasted! I wonder if it will work on the FS-ZE Engine......

ZEX here and I use the ZEX Nitrous plugs as well. No problems as of yet and I am enjoying every minute of it. The ZEX kit comes with a activation switch and then the control module activates the N2O at WOT. So it has both a switch and activates at WOT, just to let you know. My plugs look like **** to me but I took them down to a Pro that runs N2O in all of his drag cars and he said they look fine. Anyway have fun with the laughing gas and you will find out why they call it that after you smoke a couple of cars you never thought you had a chance against. hehe

Yep, it was the way that I hooked up the vacuum lines. I talked to a Zex Tech today about it. If I run it on the FS-ZE enine, i will probably run a smaller shot (35-45). This would be possible with nitrous/fuel jets from Nitrous Express or Nitrous Works. Supposedly (the Tech said) they are the same ones that Zex uses. the engine runs rich, so I hope that would help. The one concern I would have is timing of the US-spec ECU.

chdesign

You should be fine on the timing of the US ECU as is is not as advanced as the J-Spec ECU...also as long as you get fuel to the engine you can run a 50 shot general rule on dry shots is you can go half your engines rated power safely this is what the NOS tech told me and I take them pretty seriously...they know their shiznat. Anyways...do run too rich though too much fuel can be just as bad as not enough fuel....Remember its not N2O that blows engines its the detonation from runnign extremely lean that blows engines.

I installed my NOS EFI kit this weekend, gonna run like a 55 shot or so... All the wiring/plumbing is finished in the engine compartment, all that's left is to mount the 30lb. bottle in the trunk and run the N20 line from the bottle to the engine. I'll probably get around to that on Monday or so (damn, Monday's like my only day off).

I'll take some pics if anyone's interested, and prolly post them on my site somewhere.

I'd like to get a 3 guage A-piller pod to put EGT, A/F Ratio, and N20 Pressure guages, but I guess Mitch is working on that. A pod from an MX-3 wouldn't work will it? Also, what brand guages should I pick up? I want stuff that looks cool

Oh, as originally asked... There's an arming switch, and a pedal plate that activates at WOT.

30lbs Bottle????? Geez what are you going to use that for plus its gonna run you 100 bucks to get it refilled each time.

Inimical_01ES

I'm a lazy ***, the less often I have to refill the damn thing the better

Besides, maybe we can strike up some kind of "Big Johnson NOS Bottles" T-shirt idea... lol

chdesign

I didn't even know NOS made a 30lbs bottle I thought they only went to 20lbs

Inimical_01ES

Now that you mention it, I haven't even looked at the bottle all that closely (I did the engine install, my buddy mounted the bottle) Lemmie go look.

Inimical_01ES

Well, the sticker on the bottle says "Weight without gas - 14lb. 24 oz."

"Weight of gas - 10lb."

Whatever that figures out to.

Either way... thanks for the correction!

chdesign

Its a 10lbs bottle thats what every NOS kit comes with stock.

First, I have never like the way that NOS and ZEX use methods to jack up fuel pressure in order to get enrichment for the amount of nitrous injected into the engine. That's the band-aid method of doing things...

But if you must have one, then any of the current kits on the market will work just fine. Just remember it's not any safer to use a dry kit over a wet kit and I can outrun you with a wet kit at the same hp setting every single time.

I like wet kits personally because they create more torque than dry kits.

If your buying a kit based on price alone, you should do some research first. Going with this or that company has little to do with how good a kit is. Tech Support isn't everything either. I can atest to how BAD NOS' tech support can be. Venom's isn't much better.

If you want to base it on that, I would say The Nitrous Works, Top Gun and Nitrous Express are all top noch.

Based on retail pricing alone, The Nitrous Works kit wins hands down in most cases. But who pays retail?

If you want the lowest price for a new kit, visit www.nitrouswarehouse.com and talk to either Julie or John Steward. All their single nozzle EFI kits go for under $500.

Here's a basic shopping list -

At least one set of 2 range colder stock plugs or NGK plugs. ZEX plugs are over-priced...

Magnecor 8mm or 8.5mm ignition wires (stocks are junk)

MSD, NOS or Mallory "Windows" RPM switch. Not a must have, but I would run one...

NOS, ZEX or Nitrous Express bottle heater. Again, not a must have, but you want your nitrous to work it's best at all times right?

Other upgrades I would consider -

Larger cat-back exhaust system or replace the stock muffler with a higher flowing unit.

Nitto or BFG Drag radials

If your running a dry kit or you know little to nothing about nitrous in general. I suggest picking up Sport Compact Nitrous by Joe Petit. You can find it at your local book store that carries automotive related books.

Nitrous is highly tunable and the cheapest form of induction there is.
