Nitrous Build
As the title says, I'm going the Nitrous route with my ls2 Corvette. I have decided to go with a nitrous kit from NX from the forums suporting vendor! I wanted to ask the fellow forum members what else would you all recomend as far as parts & any tips. I want to run a 150 shot with a plate kit but i want to have full NA potential when the nitrous is off. I have been looking into Lingenfelter's LNC-2000 for this.
My following mods are: PRC heads, Cam, Varararam air intake, kooks longtube headers, SLP exhaust, FAST 102 throttle body & Nick Williams 102 throttle body, and an Elite Engineering Catch can.

I don't like the LNC-2000. It's basically a timing tricker that changes the iat signal to trick the ecm into pulling timing. The problem with this is that now the ecm can't see the actual iat's. It will pull the amount of timing you require for nitrous activation but will no longer be able to pull or add any timing based on actual iat's. If you really want full potential when the nitrous isn't being used without changing your tune, I would look at the DSX flex time box. Do you have Hp Tuners? You will need some type of tuning device to change the timing in the tune.
You also probably want to use a fuel pressure safety switch and a window switch just to help protect everything.
Just me personally, I was always afraid of running some of the cylinders lean so I went direct port with my ls6 and a standalone fuel system. At 150hp you will probably be fine, but you don't want your fuel pressure to drop and the standalone is great peace of mind. Otherwise you might look at changing fuel pumps, or adding a boost a pump.

I am not sure where the Fuel Pump Maxes out on a LS2 but being H/C and Adding a 150 shot would be dangerously close. If you are wanting to spray 150+ you should look into a Standalone, Upgraded FP, or Pump booster.
I am only running a 125 shot on my cammed LS3 for now while I am waiting for the remaining parts of my Standalone to show up. Then the sky is the Limit, fuel side at least.
I have looked into the Lingenfelter LNC extensively and think its a pretty cool piece. Being that i'm on such a small shot I am only pulling a few degrees of timing so the NA performance isnt THAT far off. DSTEK's piece is really cool too as long as you have a tuner.

The LS2 fuel pumps are generally good for about 150HP over STOCK. So if you are already H/C, that may affect your available fuel supply for nitrous. THE LNC-2000 is a great little box for pulling timing. It doesn't work by changing the IAT's, instead it actually changes the voltages inside the coils. The LNC has nothing to do with IAT's, so your ECM will still be able monitor them. I would recommend getting your fuel pump upgraded, first. Or, go with a dedicated fuel system that'll take your engines fuel system out of the nitrous loop.

Edit: I stand corrected. I didn't realize the LNC pulled timing after the ecm. It was explained incorrectly to me at some point apparently. I still don't like it as I can't log with Hp Tuners and see the timing being pulled as the ecm is not pulling it. I'm sure it's much better than a timing tricker though as I thought it was.

Andy. The voltage change inside the coils is for the rpm limiter and launch control, but that doesn't affect the timing. Let me know if I'm missing something. My understanding is the timing is pulled with the iat sensor.

The downloaded log can display:

Gear Position
TPS Voltage
Fuel Pressure
Nitrous Pressure
AFR
Nitrous Ramp
Fuel Ramp
Timing Ramp
Also, when combined with the LNC-2000 it makes wiring in the 2-Step much easier, since it uses the clutch input from the NCC.
Without a doubt the LNC-2000 is a powerful little timing retard/launch controller. But, to get all you can out of it you'd need the NCC-002.

Yes I do have a tunner where I live.
So the lnc-2000 will do the job? Or is there another timing box better than this one?
My goal for this is to have a drag race setu-up car that I can turn on the nitrous & have that extra push at the track. Then when it is off be able to cruise without worries of timing

LNC-2000 and timing retard
You can data log the amount of timing retard being taken out by the LNC-2000. The gray output wire is just for that. The gray output wire provides a 0-5 volt out signal that indicates how much timing is being taken out.
As someone else pointed out, you can log this with the LPE NCC-002 nitrous controller since it has built in data logging but many (most) other data acquisition systems can also accept a 0-5 volt input.
The HPTuners MPVI Pro and the EFILive FlashScan cables both have analog inputs that can be used to log this data and then you will know when timing is being taken out and how much. In EFILive they even have a predefined calculated channel configured to convert the voltage to degrees of retard (but it isn't complicated math anyway).

This is how my car is set up. they said I am losing about 40rwhp with a nitrous tune. Still drives just fine with no side affects
