wuts the best kit for the 3.4 dohc (nirtous)

[RedZMonte]

depends on how crazy you want to go, low levels i would run dry but anything like 75+ i would consider a wet kit. I would investigate the ZEX kit, thats what i was gunna run before i went the turbo route.

for some reason i thought dohc engines in general didnt like nitrous. i may be wrong though. i just heard that somewhere

[Superdave]

I don't think Nitrogen dioxide is a good thing to inject into your engine, you should try N2O (Nitrous Oxide).. i hear it's much more effective.

[lumina4doorsleeper]

ha yea sorry.....but i was thinking more along the lines of a 50 shot or so

[Superdave]

wet 75 is as far as i'd go unless you can tune the engine and you have a wideband.

I ran a wet 100 on a untuned ecm... It got me a 13.818 with a stock 3400

My 13.511 below was on my current engine and I didn't have time to tweak the fuel, thats why it says untuned... I did hit 13.7:1 a/f during the run... rut row!

Now I have more invested I'm think of direct port or a 150 shot in the future... if not both.... lol

I should really get a spare motor on a stand... haha

A guy sumwhat local to me ran a 50 and a 75 dry without problems.. moved him from 17's to low 15's (5800ft elevation). Again if you run dry its a good idea to have a Wide band O2. if you lean out it could cost you a motor. Wet will be a tad safer because your adding Fuel as well as N2O, but from what i understand the fuel likes to pool up in the DOHC intake manifold.

Direct port should solve that issue... LOL

I wish I could afford these.



Only $54 EACH!

[lumina4doorsleeper]

Why explain again when Google can do the work...

[Jake91]

would a 50 shot dry yeild the same results as a 50 shot wet?

[3400-95-Modified]

Could if your injectors could support the increase needed by them. And then your N/A running would probably suffer since they are set to run so rich.

I personally don't like dry kits,i've always ran wet.
That's just because I like to eliminate variables for safety.
Narrows down the possible problems (most of which are catastrophic).

As for a good nitrous kit,I honestly don't know which is best.
I've used sniper,harris speedworks and zex products. I really really like harris speedworks.
They are very affordable and the solenoids are rebuildable.

Are you installing etc.. yourself? and have you ever used it?
My suggestion to you would be to pick up a book on nitrous oxide. When I first used it I bought one and read it.
After learning the basics you can easily put together a kit (depending on resources) for half of what they cost.
My honest opinion is that nobody should use nitrous without first having read and understood everything about it.
It's awesome stuff,and really safe when used correctly.

If you've not ever used it and don't plan to buy a book and read it than buy a kit,as they will at least have WOT switches etc.. to guard against oopsies you get from learning nitrous the hard way.
I live dangerously,lol,I've got an arming switch and pushbutton and I purge through the motor when staging.

Purge through the motor? how's that work? I have a second solenoid that I have on a push button that purges out my cowl.
