Cold Fusion...they do look just like TNT dont they? I always have a hard time telling them apart.
Dont know what its worth...the noids are new as are the custom polished rails, and all fittings. The NOS Noszles are used, it will also come with a 10 lb bottle and feed line. Ill probably put it on ebay with a $999 reserve. The LS1 intake and injectors are just for mock up and shipping. This will fit an LS6 and FAST intake since its a Noszle kit. Just take it off this intake and install it on whatever its going on (LS6/FAST). I will test fit it on my FAST intake to be sure.

I havent tested it yet. Its not the cups thats the problem on the NXL. Its the rails/lines themselves.
But I did add a few things to these rails to lessen the lean spike issue. The nitrous passages are a bit larger in diameter than the fuel passages. This should slow down the nitrous and soften the nitrous hit upon initial activation. I had these rails custom made to my specs. You can also do alot of other things to be safe with this setup and avoid the lean spike. You can mount a FPSS at either end of the fuel passage. There is a threaded hole that the FPSS could go in on both ends. You could install the FPSS in this hole and wire it so it controls the nitrous noid. Adjusting the fuel pressure activation point up or down will alow you to "tune" the lean spike out. In other word...the nitrous noid will not open until sufficient fuel pressure is built up inside the fuel rail passage. This delays the nitrous momentarily avoiding the lean spike. This is common with alot of direct port setups.
The Cold Fusion noids work great. Never had a problem with them.

initially these rails were for regular nozzles that have fittings above each other. So the two set of holes on either side of the rail are mirror image. But with the Noszles they are side by side and that just they way they had to be hooked up. They are still nitrous to nitrous and fuel to fuel.

Well..I guess the solenoids are capable of about ~175 hp shot per side even though they are rated to 200 hp. So I would say about a ~350 max using these noids maybe a tad more. Swap to the next larger noids and it would be 500+.
