nos on an si

thmper4u · 08-05-2006, 03:59 AM

I just bought a zex nitrous wet kit for my 06 si and with the fly by wire throttle there is no way to put a throttle contact on it so Im guessing Im gonna have to wire into the TPS somehow, does anyone have any experience with this or know how to go about doing it?

Kurt · 08-05-2006, 01:29 PM

top. I have the same kit and installed it last night but couldn't find the TPS

thmper4u · 08-05-2006, 04:02 PM

So was you able to get it to work with the full throttle method or are you still workin on it? thanks

Kurt · 08-06-2006, 12:24 PM

I'm finishing the install today. I'll let you know how it goes and what I had to do

thmper4u · 08-06-2006, 02:17 PM

Thanks Bro, that would be a tremendous help, I checked the tracking # on mine and its scheduled to be here in th morn.

Kurt · 08-06-2006, 08:02 PM

Man, that was easy once we found where the TPS was. Just clamped a wire into it and turned on the zex box and held the pedal down for 10 seconds and it was programmed.

talk about a whole new car now.. and im only spraying 55

I'll take a picture of where i tapped into the tps in a few minutes

Kurt · 08-06-2006, 08:31 PM

ok, it's really hard to see but the tps is right behind the throttle body on my car (R18) we had to pull off the rubber cover and there were a few wires for the plug - the wire we tapped into was yellow

it's hard to take a picture of, sorry

Tom1222 · 08-09-2006, 10:55 AM

Is the ZEX kit for the R18 and the Si the same? Also I can see it work well with the R18 but aren't you worried about the Higher Compression in the Si?
Seems to me that it would run a higher risk of detonation. I bet Nitrous is a lot more effective in the R18 than it will be on the Si because Nitrous accellerates the combustion process and increases compression which could be dangerous on an already High Compression engine as the K20 in the Si.

Be sure to hook a laptop to your car so it can tell you if there is "Danger to the Manifold!" Monicaaaaa!

Did you get it installed yet? How do you like it? Do you have a part number for the kit? I am very interested. Do you have to drill into your intake?
I have the Injen Cai on mine and wonder if it would work with that?

**twistedframe** · 08-10-2006, 11:54 AM

as long as you are getting enough fuel, whcih you will be b/c you are using a zex wet kit, you should have no worries about detonation especially on a small shot. (small shot = <100)

Tom1222 · 08-10-2006, 12:08 PM

excellent! Do they make a kit especially for the 06 Honday Si or do I just order a universal kit for Honda?

thmper4u · 08-10-2006, 05:38 PM

well the part # for the kit is 82021p and thats the wet kit in which you have to tap into your fuel system and no I dont have it installed yet, Im goin to Nopi in knox. this weekend to show my car and didnt wanna tear it down before hand, I just went today and got my friend that works at the local honda dealership to print me off where the throttle postioning sensor is and what wire to tap into on the si, and I have zero experience with Nos so I dunno if it may be more harmful putting it on the K-20 or not but I did alot of research about the different kinds of applications and kits and Zex claims it can be put on any engine safely if used correctly, the kit came with several different jets for different horsepower and I'm only gonna put the 65 shot jets in it which is considered to be "no danger" heres some of the things I read up on the zex kit:
The ZEX "Wet" Nitrous System has the most advanced features of any "Wet" nitrous system on the market. All components, such as the solenoids and activation electronics, are factory pre-assembled inside the "Nitrous Management Unit". This ensures you will be spending less time in the garage installing the system and more time out having fun. The patent pending "Fuel Shear" technology used in ZEX's nitrous nozzle places the enrichment fuel directly inside the high-speed nitrous plume exiting the nozzle. This results in the most complete atomization of enrichment fuel possible. Super-fine atomization of enrichment fuel ensures maximum horsepower and eliminates fuel puddling that can cause intake backfires. Even the way ZEX activates the nitrous system is unique. Instead of relying on crude micro-switches or push buttons, the ZEX "wet" nitrous system uses advanced electronics to "learn' the throttle position sensors voltage curve. It then programs itself for your specific vehicle and, when armed, will only activate the nitrous system at wide-open throttle. This ensures perfect engagement every time the nitrous system is used. Advanced features like this make the ZEX "wet" nitrous system the easiest to install, the most powerful, and the most reliable system on the market.

*

Designed to work safely on stock type engines, but is also engineered to perform flawlessly on highly modified turbocharged and supercharged combinations. The ideal nitrous system for any fuel injected vehicle.
*

All major components are factory pre-assembled inside the "Nitrous Management Unit". Easy, plug and play, two-hour installation.
*

ZEX Nitrous Systems have an advanced, patented feature called "Active Fuel Control". This feature monitors nitrous bottle pressure and adds or subtracts enrichment fuel so the engine never runs too rich, or too lean, when you engage the nitrous system.
*

ZEX "Wet" nitrous systems activate at wide-open throttle using advanced electronics that monitor your engine's throttle position sensor. This makes using your nitrous system very easy and reliable.

And it lists the si as a suitable application so I hope it turns out alright, I'm not very hard on my engine either, I mostly granny it around and never run it above 5 geez, I ran it 4 passes at the track and that was the only 4 times its ever touched 8000, I usually shift at 7500 if I am gettin into it so I'm not gonna be using it much, mostly just wanted it to bring my quarter mile time down in the 13's for bragging rights, I just dont want my car smoking and looking ragged out by the time it has 30,000 miles on it.
