See sig for my mods. I want to add a wet nitrous kit, but I am stuck between NX and TnT. I don't know anything about nitrous, but I have been told to add a Walboro intake pump, and to stick to a 100 shot. I am currently at 414RWHP/387RWTQ. I will add a NX bottle heater, purge, either a WOT switch or a NX TPS switch(which is better?), window switch and a fuel pressure safety switch. I wouldn't mind having a remote bottle opener but the NX one is the best, so I have heard and it only works with the NX kit unless you modify it. What do you all think, Nx or TnT. With my current power and the use of a 100 shot I should at very close to the limits of the stock bottom end.

 

Walbro intank is a must. I would consider a window switch a must at your HP level as well along with a FPSS. I would consider something to take out some timing at that HP level as well depending how much timing your seeing now. If your on the ragged edge of detonation running NA you will definately want to pull a few degrees or run race gas.
As far as which kit...hmmm...thats a toss up. TNT and NX are both quality kits IMO.

 

I have the TPS switch in my car and it is bad ***. You dont ever have to worry about the lever on the WOT switch moving around and possibly not activating the kit. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I have a NitrousWorks EFI kit that is wet (441.25 from Summit). I have to buy an extra fuel line ($25). I use Harlan's window switch and the microswitch that came in the kit. This kit is has jets from 25 to 100HP. I bought a second set of jets for up to 175HP, but only use 150HP. I was told that the stock pump is OK of up to 150HP of wet shot. Dry nitrous guys need the extra fuel volume to keep up. I have several passes on my system and not a hint of problems.
