Told you it would be cheaper to just buy the book. Can't beat $10 delivered. You'll like it. Very informative.

 

Are you going to buy their kit.

 

im thinkin of puttin a NOS kit on my Jazz, i got a 1.4 idsi A/T, probably a NOS Express, do u think my tranny will hold on a 50shot?

 

Yes it will hold 50shot. I have already bought a kit, and I will start first with 25shot and go up. Are you going to order from abroad.

 

No im gonna gettin it locally they have a dealer for NOS Express here, so i just wanna know wat i need to do and wat i need to know, before i install it

 

I think you will need to use colder plugs. Also buy heater that will make the pressure higher, so you will have better performance.

 

Anybody using NOS on CVT? How is it?

 

Any update on NOS in Fit.

 

I just read the book and it has real good information about NOS. Trev the owner of Wizards of NOS and writer of the book explains a lot about NOS. I suggest people to buy the book if they are interested in NOS. I also suggest to go to video clips section in his site and check the Jag with NOS that beats very fast cars. I love this clip so much and everytime I watch it, it makes laugh.

 

So is 1200 best pressure.

 

**Zombie Resurrection**

There was a LOT of excitement in this thread 7-8yrs ago. Has anyone else ventured out and did a nitrous setup on their Fit? Wet or Dry? What 1/4 mile times have you gotten?

This was a very pleasant read. I'm considering getting something pieced together since I'm out of N/A modification ideas at the moment and tuning is not an option. I have plenty extra bottles. May as well call around tomorrow and get this moving. And yes, the CVT would be a concern. Already researching a lot more into that as well.

B.S. predictions are telling me a 14.6 1/4 mile with a 35hp shot, 14.2 1/4 mile with a 50hp shot and 13.8's with a 75hp shot. Now THIS is funny.

If I do get a kit, I'll be running a wet shot and one step colder plugs then stock (If going over a 50hp shot jet). 92-93 octane of course. Nothing I can do with timing advance at the moment.

I've toyed with this idea for years, in for resurrection.

Zex has a "kit" for the Fit but i'm sure it's nothing you couldn't put together piecemeal.

 

Awesome! I didn't realize this. Thanks!

Zex Wet Nitrous Kit

I've sent them an email and am awaiting their reply. Only concern is of the fuel supply since I've read direct injected engines have very high fuel pressures.

Trying to reach username Lyon[Nightroad] on his impression of nitrous as well. And a couple others that had it installed here. Really interested in before/after 1/4 mile trap speed (and time but not as important).

 

**Quick Update**

Zex's reply to the email I sent them.


So my concern was confirmed about the fuel pressure and hooking it up to their purple box. *sigh*

On the flip side, my concern for a dry kit is that it usually relies on the fuel pressure to be bumped up through the fuel injectors. You ain't bumping fuel pressure up on an already high pressure system. Wouldn't know how if you could.

I have some more homework to do on this one. Gonna look at how nitrous is added to other direct injected applications (If it is). Your input is valued!

Here's my original email to Zex. I thought I asked them about the fuel pressure issue but that was my email to DynoTune Nitrous -->

This was on a GE... and I'll say this much... he eventually went through 2 engine swap/rebuilds.

 

That was from the turbo though wasn't it?

One blew around 18psi, I wasn't aware of the second motor

 

That was the second motor... he bent a rod and then pieced parts from the original and second engine for the rebuild.

https://www.fitfreak.net/forums/2nd-...-rod-pics.html

I think he blew a head gasket in the first motor due to a little too much happy gas... though he only found out later, after removing the nitrous oxide system..

 

Got it, thanks for the clarification.

It's fun going back to read through those old threads, lots of good information.

 

I just searched a majority of his threads for this information and could not find it. Here is what I found though and this was before he did his turbo build and before removing his nitrous.

At first he said this -->

Then he said this later in the thread -->
So no problems with his nitrous from what I can see. I do like the fact that he was using an auto (I'm an auto junkie) and that it seems on a 55hp shot, he was right where I'm at now. I'm dying to find out what I could do on a 55hp shot, let alone a 75hp shot (max). Baby steps! The compression ratio of 11:5 is no joke. Too bad he went with a Focus ST. I'm very interested in his feedback. He was last on a month ago or so.




As for this direct injection setup, I've been searching all over the net with no confirmation on anyone that has been using this with direct injection. I'd feel safer with a wet kit. Apparently, direct injection setups have two pumps. A 'normal' pump that pumps to the high pressure pump, which pumps to the injectors via high pressure lines. Maybe there is a way to tap the first pump that is not high pressure, without impacting the pressure it is sending to the high pressure pump. Research!!

 

My experiences with NOS is about 10 years ago at least. I ran it in my SOHC nonVtec civic. Best times I even ran on an 80 shot was I believe in the high 13's like 13.8-13.9. Being the D16's have a better head then the L15 and a better weight I don't see 13.8 on a 75 shot. Hell I could be wrong. One thing I will say is wet NOS is better then dry. I learned that the hard way.
