I'm very seriously close to buying this kit. Someone tell me why I shouldn't. And If I should, what last words do you have for me? What do I need to know? What other accesories to the kit should I purchase? Excuse the questions, but I'm about to make a life changing decision!

 

haha none you will be fine. if you dont feel like doing it take it somewhere to have it installed. you can buy the spark plugs for $20 and kit is cheaper to buy on ebay.

 

Last words for you: do NOT get power-greedy, especially with a higher-compression 1.5L engine. If you do, you WILL ruin it.

You may also want to check your valve clearances more often, since nitrous likes to eat exhaust valves.

EDIT: This doesn't mean "don't buy it", it means be careful how much power you try to get out of it.

 

At the lowest setting, you will get quite a bit of improvement in acelleration. It will put a big smile on your face. Like Scratch said, don't get used to it and then want more. Use it sparingly. The stuff ain't cheap to fill all the time. When I first got my nitrous kit, it was all gone within one day.

Don't forget to send us a pic of that big smile when you use it for the first time.

 

yep people blow through nitrous, i fill bottles and have a guy that fills up 5 bottles every friday and he mainly uses it for purge because i installed the rapid fire module and led light from ZEX

 

I assume you can refill the Zex bottles anywhere that has a nitrous pump? Doesn't have to be a Zex dealer does it?

 

thats correct... all bottles are the same from neck down, other manufactures use different valves(hiflo,etc.)

 

I ran the Zex kit for a few months on my fit. It ended up pooling in the intake plenum and blowing up. It was quite impressive, actually. Scared the everloving daylights out of me. Fireball over the windshield and everything. I'm still running that motor, actually. Compression of 215 across the board.

Nitrous can be safe as can be, but it's way easier to half-ass a nitrous setup than it is a turbo or supercharger.

 

Does that mean you were running a wet kit?

 

Wow, that would have been awesome to see. Pics?

So, the nitrous didn't vaporize and you had predetonation. Good thing your engine survived. Where along the intake was the nozzle placed?

 

Yes. If there's a dry kit that manages fuel correctly, and provides enough, then it would be superior. Dry just means it uses the stock fuel system to add the fuel required for nitrous. It's actually safer than wet, as you can't get a nitrous backfire from a dry kit.


EDIT:
I missed the rest of your post - There was no preignition, or detonation (they are separate phenomenon). What I had was a pooling of FUEL in the intake, and along with the gaseous nitrous oxide (it boils immediately upon exiting the nozzle), it created an explosive mixture in the intake plenum. When I let off the gas, I had an intake backfire (which is actually pretty common), and it ignited this mixture.

EDIT x2: The nozzle was 4" before the throttle body, just as the instructions stated.

 

Thanks. I'm trying to keep the noob questions to a limit, but I'm 99% sure I'm going to get the kit, so it's just nice to be able to get all this info from experienced users on fitfreak.

 

whatever you do, if you run a wet kit, make ABSO-FUCKING-LUTELY SURE that the nozzle CANNOT, UNDER ANY CIRCUMSTANCES shift left or right. I think mine shifted and started spraying at the wall of the intake pipe causing my pooling problem.
