Car- 1991 NSX auto 45K miles with Z-tek Headers/exhaust, AIS scoop with Uni filter, SOS Big bore throttle body, Comptech test pipes, Zanardi front and rear sway bars, NSX-R Chassis bars.
I think I finally almost got this nitrous install done. I thought others might be interested. It all started with BadCarma and his knowledge. I started with a direct port nitrous and wanted to have a shop with lot of nsx experience to do my install so I drove to Science of Speed in Arizona. They were having trouble installing it direct port so I ended up getting a wet kit installed there. NX wet kit with remote bottle opener, auto bottle heater, Wide open throttle (WOT) switch.
Than finished the install at a local performance shop and added a purge kit, a down pipe(necessary for the track), Fuel pressure safety switch, Guages Air/Fuel and nitrous pressure. and now currently installing a NX/FJO racing Progressive controller that controlls how much I spray at every RPM, has a first gear lock out, Rpm window switch, lot of other features but not as many as The maximizer 2 I should of got where you can controll in each gear what rpms and how much you spray but its real expensive.
First before the Nitrous install I went to Rob in Valancia to make car ready for nitrous use. These steps are crucial before you start spraying.
1. Compression test and leak down test. This is the deal maker or breaker.
2. Change spark NGK BKR7E gaped at 0.35 (one step colder, or 2 if you are pushing more than 100 hp shot, in that case it will be NGK BKR7E-11's
3. Ignition Coil check for spark and intensity- Validate if ignition is putting out enough spark ( OEM LEVEL) make sure check each coil pack is in spec.
4. Replace fuel filter.
5. Install Oem injectors that have been cleaned to excelent flow conditions by RC' Eng. Or if you can afford to pay a little more get them RC' enginering to clean and have them make it peak hold 15% more flow.
6. Install new Fuel pump or you can get the High Flow Walbaro 255lph Fuel pump. I got the Walbaro High flow fuel pump
7. Fuel pressure regulator. Validate pump is working at proper flow level.
Raise the OEM fuel pressure regulator to full time 12v.
8. Dyno to see how the car running. Make sure A/F looks good. ( I did this with a 45 shot and it looked good )

Here is a Dyno Result with just a small 45 hp shot:

Look at the Torque and Horsepower numbers big difference even with a small shot. No other way than NITROUS to make such TQ numbers so quickly.
Now we are installing FJO racing Progressive controller.

And also using my dyno results to determine how much hp nitrous spray to add at what RPM. So I will spray 25-50% hp more at each 500 rpm than the current hp its making now in each RPM. So when the nitrous is activated it will run like a super/turbo charger and be safe as it can be. Might not be able to use it all day everyday but ALWAYS when I need it.
This is a great setup it will only run when the fuel pressure/oil pressure is optimum, only at Wide open throttle, Only at the set RPM 3000-7000 rpms, not hard on the drive train or engine as there is no hard nitrous hit, it progressively increases hp/tq as the rpms/gears increase.
Next thing is go to Rob and get my timing belt/water pump and than ProSpeed and have Brain do my ECU tune up on live dyno and see if I can make the car run even better on and off the nitrous. Than to the track for some quarter mile times on and off nitrous. I haven't used the nitrous yet just on the dyno. I am going to use it when its all done sometime this week. I just thought I would share as I would love to see more nsx's using nitrous. I would love to see a direct port nitrous NSX.
