Finally got to test out my nitrous system from nitrous express. The kit itself was not too hard to install. I think the worst part was mounting the selenoids. The directions you get with the kit are good, self-explanatory and straight forward.

Also, for the installation, make sure that you tap the throttle body elbow carefully. Don't want to position the nozzle and not be able to close the hood. Another tip for the installation is when tapping in for the fuel. Myself, I tapped the fuel rail itself. They said in the instructions to either cut the line or tap the rail. Well, the hose clamps they give you are for silicone and vacuum hoses, and I just didn't trust the two clamps to hold my fuel hose together running about 40psi. So, i tapped the rail, which was easy by the way. Just make sure that you clean it up good before you reinstall. With tapping, make sure to use the "lock-tite" you get with the kit. It is some good stuff.

Now to give out things when I experienced it. By the way, it is a 35 shot I had in. For fuel, all I have is a Walbro 255 with stock injectors. I turned the AFC back to a little more rich than what I usually run at, and turned the boost down to 15psi. For the run, which was just on the highway so I have no times, I slowly increased my speed till the WOT switch kicked in. Boost went up to about 17-18psi. There was a little punch when it finally kicked in. Not tire-squealing punch, but a nice jolt. From 100 to 120mph, that was the fastest increase speed wise.

Then made a second pass, but this time held a good top speed. RPM's were at 5000, then punched it down to WOT. The nitrous punched the car forward, with the RPM's staying between 5000-6000.

All in all, I think the kit is worth it. Personally, I expected a bigger punch, but I only had a 35 shot in. I have to play with the fuel a bit with my pocketlogger (just got it today :D ). Probably once I get it tuned nicely, it will feel like a big increase. Nitrous Express is the way to go for a wet kit. There was no problems after I ran the car as well.

Also, thanks goes out to DSMtalk for all the guys on here who helped me out deciding on a kit, installing it, and reading about your own personal experiences with nitrous. DSM's rule :cool:
 
Thanks for the review. I'm just curious, did you have to wait a long time for the kit? I sell (sold) NX stuff and I basically gave up because of the wait customers would have to endure because NX would take so long sometimes to send out the stuff. They were very inconsistent, sometimes extremely fast sometimes very very slow.. Just wondering how it went with you.
Thanks
 
Good to hear you got good results. Your right about feeling it a lot more above 100mph. Mine makes a big difference above 90mph. When you have some race gas try a 75shot from a fourth gear roll. When it comes one it pushes you hard against the seat :D ..
 
Well I have an automatic so it's a little different then they way you would do it. I power brake and hold the rpms at 3000, then I just floor it on green and the nitrous comes on right of the launch.

Please elaborate on how you tapped the 2G fuel rail.

Where exactly did you tap it?
What kind of fitting did you use?
What technique did you use to tap it? Drilled through or whatever?

Thanks

The way I tapped the fuel rail was drilling it. First, and obvious, I took it off the car. I made the tap on the top of the rail as you look at it when it's in the car. So, the line for the fuel runs out the top of the rail. I then drilled for the correct size fitting, starting out with a small bit and working my way up. I used one of the fittings that came with the kit. But you can also get a fitting at any auto store to fit the 4AN hose.

After that, I cleaned out the rail with just water and a small soft brush. Dried everything out with rags and an air compressor. Then put the fitting with the lock-tite that you get with the kit. Tightened it up nicely and put the rail back on. Ran the line from the rail to the selenoid and I was done.

Any other questions, please don't hesitate to ask. Hope this helps.
 
I'm a bit hesitant to drill into the fuel rail.

Couldn't I just use a "T" off the high pressure hose going to the rail?

You could get the B&M Fuel Pressure Gauge ($35) that mounts on the Fuel Filter and add another "T" their, for the fuel solenoid.

just a thought

Are you proposing this:
....._____

Either put the "T" on top of the other "T" like you did. Only drawback would be the height with the gauge. Or you can put the two "T's" sided by side.

can you just get a fitting like that and take off the banjo bolt? if so what size, that is the best way to do it seems to me
